refresh rate on lcd monitors manufacturer
It’s natural for anyone shopping desktop monitors to be swayed by size, shape, resolution and color quality. But depending on your business needs, you may also want to consider a less flashy feature: the monitor’s refresh rate.
Refresh rate is the frequency at which the screen updates with new images each second, measured in hertz (cycles per second). The content may look steady on the display, but what the viewer can’t see is how fast the content is changing — up to 360 times a second. The higher the refresh rate, the smoother the visual quality.
Super high monitor refresh rates aren’t all that important for office workers focused on lighter computing like word processing, spreadsheets and emails. But in more visual professions like creative production and game development, a high refresh rate for monitors is invaluable.
The standard refresh rate for desktop monitors is 60Hz. But in recent years, more specialized, high-performing monitors have been developed that support 120Hz, 144Hz and even 240Hz refresh rates, which ensure ultra-smooth content viewing, even for the most demanding visual processing needs.
Just buying a high refresh rate monitor doesn’t mean the display quality will magically improve. The monitor’s refresh rate reflects the maximum rate at which the display can change the visuals. What happens on the screen depends on the frame rate of the output — the number of video frames that are sent to the display each second.
The majority of Hollywood movies, for example, are shot and produced at 24 frames per second (fps), so a 60Hz monitor will easily offer smooth playback. But having a 120Hz monitor (or even faster) won’t provide any visible benefit to playback quality.
A 120Hz monitor has obvious benefits, though, for modern gaming platforms that animate at 100 fps or higher. A high refresh rate helps the screen keep pace with the high-twitch inputs of players and translate them into super smooth actions on screen.
When refresh rate and frame rate are mismatched, it can result in something called screen tearing. If the computer’s graphic card is pushing out more frames than the monitor’s refresh rate can handle at a given moment, users may see two half-frames on the screen at once, bisected horizontally and slightly misaligned. In short, it doesn’t look good. Games are usually configured to automatically match the PC’s graphics capabilities to avoid tearing, but running high-action visuals more slowly than intended makes for a compromised viewing and playing experience.
Response time — the time it takes for a pixel to change color — also plays a role in refresh rate. A monitor can only refresh as quickly as the LCD display can make those rapid-fire color shifts.
Particularly for fast-paced visuals, higher refresh rates and faster pixel response times reduce ghosted visuals, and ideally eliminate them. With slower tech, a high-pace action sequence may come with trailing images that result in softer, even blurry on-screen visuals.
The appeal of high refresh rates is obvious for at-home gamers looking for a responsive, hyperrealistic playing experience. And this leisure use is part of a vast global industry. SuperData reported that the video gaming industry generated roughly $140 billion in 2020, up 12 percent from $120 billion in 2019. Statista estimates there are now more than 3 billion gamers worldwide.
The nascent esports industry is already worth more than $1 billion, and companies of all sizes and sorts — including casino operators — are scrambling to establish esports gaming zones and arenas for fans to watch and play popular games like Overwatch.
In the U.S. alone, the video game industry employs 220,000 people across all 50 states, according to the Entertainment Software Association. That’s a lot of game developers, graphic artists and playtesters working in front of monitors, most of them in need of optimal visual quality and speed at their workstations. While 60Hz refresh rates may work fine for people in finance and human resources — and even the clerical side of gaming companies — people on the visual and testing side need at least 120Hz to do their jobs well.
And it’s not just gaming. While the film industry has long produced movies at 24 fps, that frame rate is a relic of times when there were different technical restraints on cameras and projection, so a faster frame rate required more expensive film. The 24 fps standard has stuck around largely because that’s what the public is used to. Today, filmmakers are increasingly pushing frame rates as high as 120 fps.
High-performance monitors with high refresh rates come with obvious visual improvements, but monitor upgrades in general bring a broader range of business benefits.
Higher-quality monitors — notably those with Quantum Dot enhancement film — offer an immense color palette and extreme color accuracy. Users don’t just see red; they see the exact shade of red the artist intended. High dynamic range (HDR), featured on high-resolution monitors from Samsung, clarifies every element of every scene — even the brightest highlights and darkest shadows — so the smallest details are fully discernible and distinct.
Premium monitors also come with built-in (adjustable) technologies that can reduce eye strain. Manufacturers, led by Samsung, have increasingly introduced curved widescreen monitors that equalize the focal distance of every part of the screen. The left and right edges are the same distance from the viewer’s eyes as the middle of the screen, reducing eye strain, as viewers don’t have to adjust their eyes as they scan the display.
High refresh rate monitors with high response times also tend to come with other premium features, such as full support for USB-C connections. With a single cable, the user can connect their PC to a monitor that functions as a USB hub for peripheral devices. This negates the need for expensive and often clunky docking stations, and can significantly reduce the number of cables at each workstation. In addition to tidier, streamlined workspaces, this also reduces the demand for IT support. With fewer connectors and devices, you tend to get fewer problems.
Around the workplace, anyone in a visually creative role will see immediate benefits from a higher refresh rate. And while those in non-visual roles probably won’t see any difference, the key may be futureproofing.
When IT and information systems (IS) teams plan capital purchases, they need to look several years ahead for potential technical requirements down the road. While high-refresh monitors may have a defined user community right now, it’s likely more use cases and worker needs will develop. Monitors with low refresh rates can’t get better, but higher-refresh monitors can serve your display needs both now and in the future.
As you consider making a monitor upgrade for your team, walk through the market drivers, societal shifts and technologies of the reimagined office in this free guide. And no matter what your industry, Samsung’shigh-performance monitorshave you covered.
Displays with a 360 Hz refresh rate and a 2.8 ms frame time are the best gaming monitors with high refresh rates you can get today. But that will soon change. Two leading makers of LCD panels are developing display panels that feature a 480 Hz refresh rate and a 2.1 ms frame time (as well as lower overall latency). These panels will be ready sometimes in 2022, so actual displays will arrive in 2023.
Both AU Optronics and LG Display are working on LCD panels with a 480 Hz refresh rate, according to two reports by TFTCentral (1, 2). LG Display is reportedly working on multiple 480 Hz panels with the first one being a 24.5-inch with a 1080p(1920x1080) resolution. The unit is projected to be ready for mass production sometime in Q4 2022, so if everything goes well, the commercial displays based on the panel will be available in the first half of 2023. AU Optronics is also developing a 1080p panel with a 480 Hz refresh rate and aims to start mass production in 2022, but there are no further details.
Not a lot of information is available about AUO"s and LG Display"s 480 Hz panels now, which is not particularly surprising given that they are so far out. Today"s ultra-high-performance 360Hz displays use a TNpanel, though the brand new 390 Hz LCDs use AUO"s AHVA (IPS-like) panels.
To handle a panel with an extremely wide variable refresh rate range — think about 30Hz ~ 480Hz — a very high-performance display controller logic will be needed. This set of chips (or one highly integrated chip) will have to include a very high-performance image processing unit, an appropriate overdrive processor, a very fast TCON (timing controller), and a general-purpose processor that will manage operation of the said units.
For example, modern 360HzG-Syncdisplays use logic specifically designed by Nvidia. In fact, the logic behind high-end displays is just as important as the panel and the backlighting, which is why development of expensive monitors takes so long.
These 480 Hz panels are designed for monitors aimed at professional gamers who want maximum performance to maximize their potential in various eSports competitions. The market of such displays is rather small, yet lucrative. Furthermore, such high-end displays serve the same purpose as other halo products — they promote the manufacturer"s brand.
As of Test Bench 1.2, there are two separate test boxes that we evaluate, and they are tested at the same time. The first is the Refresh Rate box to determine the display"s native and max refresh rate depending on its connection type and the signal sent. We test it with a test PC using an NVIDIA graphics card, usually an RTX 3000 Series card, and the test is done at the monitor"s native resolution.
As of Test Bench 1.2, there are two separate test boxes that we evaluate, and they are tested at the same time. The first is the Refresh Rate box to determine the display"s native and max refresh rate depending on its connection type and the signal sent. We test it with a test PC using an NVIDIA graphics card, usually an RTX 3000 Series card, and the test is done at the monitor"s native resolution.
The max refresh rate denotes the maximum frequency the monitor can refresh the image, as supported by the manufacturer. It includes the factory overclock that comes with many gaming monitors. Note that this only looks at officially supported overclock modes; it may be possible to overclock most monitors through overclocking tools and custom resolutions, but we don"t check for this.
We check this max refresh rate with both DisplayPort and HDMI connections, and this is done by sending an 8-bit color depth signal. For many monitors, you can only achieve the max refresh rate over a DisplayPort connection because DP 1.2 and 1.4 connections have higher bandwidth than the older HDMI 2.0 bandwidth, which is still found on many monitors.
We repeat the same tests to determine the max refresh rate, but by sending a 10-bit signal. It"s important for HDR games as HDR requires 10-bit color depth, so with this test, you can see the max refresh rate at which you can play. Due to HDMI 2.0"s bandwidth limitations, many monitors have a limited refresh rate over HDMI, and once again, you"ll likely need to use the DisplayPort connection to use the monitor to its full potential.
The second test we do is to determine the VRR formats and the range at which it works. We use PCs with RTX 3000 Series and RX6600 XT graphics cards to test the G-SYNC and FreeSync support, and we also use NVIDIA"s G-SYNC Pendulum Demo and check games to make sure VRR is working properly across the refresh rate range of the display. The Pendulum Demo can be used to test any VRR format supported by the PC and monitor. We look to see if there"s any screen tearing or other unusual artifacts in the demo.
Unfortunately, we don"t officially test for HDMI Forum VRR support like with TVs, but you"ll know if the monitor supports HDMI Forum VRR if the VRR feature works with the PS5 in the PS5 Compatibility Box.
We check for FreeSync compatibility with a PC with an AMD Radeon graphics card, usually RX6600 XT. This test is important if you"re planning on using the variable refresh rate feature with an AMD Radeon graphics card or with an Xbox One S/X or Xbox Series S|X. There are three possible results for this test:
Yes:The VRR works, and most monitors that work with AMD graphics cards fall under this result. As long as the manufacturer advertises FreeSync support, or if AMD has it on their list of supported monitors, then the monitor gets a "Yes". We don"t specify whether it"s FreeSync, FreeSync Premium, or FreeSync Premium Pro certified, we just know that it works.
Compatible (Tested):If the VRR support works with an AMD graphics card, but it isn"t advertised on the manufacturer or AMD"s websites, then it"s considered "Compatible". Not many monitors are like this now, and as long as the VRR works, there isn"t a difference in performance versus a monitor that has the certification from AMD.
Like the above test, we check for G-SYNC compatibility with a PC that has an RTX 3000 Series graphics card. This test is only important if you"re planning on using the monitor with an NVIDIA graphics card. Unlike with FreeSync support, the different results can have an impact on the monitor"s performance with an NVIDIA graphics card, and NVIDIA is tighter with their certifications.
No:Some displays simply aren"t compatible with NVIDIA"s G-SYNC technology as there"s screen tearing. This is becoming increasingly rare, as most monitors at least work with G-SYNC.
Compatible (NVIDIA Certified):NVIDIA officially certifies some monitors to work with their G-SYNC compatible program, and you can see the full list of certified monitors here. On certified displays, G-SYNC is automatically enabled when connected to at least a 10-series NVIDIA card over DisplayPort. NVIDIA tests them for any compatibility issues and only certifies displays that work perfectly out of the box, but they lack the G-SYNC hardware module found on native G-SYNC monitors.
The simplest way to validate that a display is officially G-SYNC compatible is to check the "Set up G-SYNC" menu from the NVIDIA Control Panel. G-SYNC will automatically be enabled for a certified compatible display, and it"ll say "G-SYNC Compatible" under the monitor name. Most of the time, this works only over DisplayPort, but with newer GPUs, it"s also possible to enable G-SYNC over HDMI with a few monitors and TVs, but these are relatively rare.
Compatible (Tested):Monitors that aren"t officially certified but still have the same "Enable G-SYNC, G-SYNC Compatible" setting in the NVIDIA Control Panel get "Compatible (Tested)" instead of "NVIDIA Certified". However, you"ll see on the monitor name that there isn"t a certification here. There really isn"t a difference in performance between the two sets of monitors, and there could be different reasons why it"s not certified by NVIDIA, including NVIDIA simply not testing it. As long as the VRR support works over its entire refresh rate range, that means the monitor works with an NVIDIA graphics card.
Yes (Native):Displays that natively support G-SYNC have a few extra features when paired with an NVIDIA graphics card. They can dynamically adjust their overdrive to match the content, ensuring a consistent gaming experience.
Like with certified G-SYNC compatible monitors, G-SYNC is automatically enabled on Native devices. Instead of listing them as G-Sync Compatible in the "Set up G-SYNC page", Native monitors are identified as simply "G-SYNC Capable" below the monitor name. Like with FreeSync, we don"t specify if it has a standard G-SYNC certification or G-SYNC Ultimate, as both are considered the same for this testing.
For this test, like with the two previous ones, we make sure G-SYNC is enabled from the NVIDIA Control Panel and use the NVIDIA Pendulum Demo to ensure G-SYNC is working correctly. If we have any doubts, we"ll also check with a few games to make sure it"s working with real content as well.
This test represents the maximum frequency at which the variable refresh rate feature can be enabled and work properly. We test this using the NVIDIA Pendulum Demo, and most of the time the "VRR Maximum" is just the same result as the "Max Refresh Rate", but there are some cases where the overclock causes some issues with the VRR.
Our VRR Minimum test checks for the minimum frame rate at which the VRR feature is still working properly. Like the previous test, we check this using the NVIDIA Pendulum Demo, gradually reducing the frame rate until the screen starts tearing. If a monitor supports both FreeSync and G-SYNC, we also check the range of each. If there"s any difference between them, we put the widest range as the result and note the difference in the text.
Because we test for the effective frame rate and not the actual refresh rate of the display, our minimum refresh rate is frequently lower than the minimum reported by the manufacturer. It"s because many monitors support a feature known as Low Framerate Compensation (LFC). If the framerate of the source drops below the minimum refresh rate of the display, the graphics card automatically multiples frames to bring the framerate back within the refresh rate range of the display. Since we look at the effective VRR range, we don"t differentiate between monitors that use LFC and monitors that can reduce their actual refresh rate.
We repeat the tests above over both DisplayPort and HDMI connections and list which connections the VRR feature works on. Most of the time, the VRR works over both connections, but because the maximum refresh rate can be different over HDMI, we also include in the text if there are differences in the range. Also, we"ll include in the text which connections you need for the G-SYNC or FreeSync VRR to work, as many G-SYNC compatible displays only work over DisplayPort connections, but higher-end monitors with HDMI 2.1 bandwidth now support G-SYNC over both connections.
While refresh rate has the biggest impact on the clarity and fluidity of motion on screens, you also need a good response time to have smooth motion handling. We measure this as part of our motion blur test, and it refers to the time it takes for the display"s pixels to switch from one state to another across a variety of transitions (for example, from showing black to showing white).
The relation between them is found when looking at what we call frame time. The frame time refers to the length of time a frame is shown on screen. For example, a 120Hz monitor has 120 cycles per second, so every frame appears every 8.33 ms. If your screen"s average pixel response time is higher than this, it can cause blurriness since the pixels rarely have time to complete their transition before switching to displaying the next frame. Because of this, it"s important to consider our entire motion section and not only the refresh rate to evaluate the motion capabilities of a monitor.
The refresh rate also has an impact on the input lag of a monitor. There"s more of a direct relation here than with the response time, as the lower refresh rate helps result in lower input lag. A 60Hz monitor results in a frame time of 16.67 ms, and because we measure the input lag in the middle of the screen, the minimum input lag for a 60Hz display is 8.33 ms (it takes half the frame time to refresh in the middle of the screen). However, a 360Hz monitor has a frame time of 2.78 ms, which a minimum input lag of 1.39 ms, so you get a much more responsive feel with a higher refresh rate monitor.
There isn"t much to do to enable the maximum refresh rate of your monitor. It"s mostly a plug-and-play affair and doesn"t require much tinkering to get working right, as long as your graphics card can take advantage of the maximum refresh rate.
Change the refresh rate setting on your computer. You can do this either through your graphics card"s driver settings or in Windows through the display adapter properties panel found in your display settings.
Some high-end gaming monitors have an Overclock feature that allows you to boost your screen"s refresh rate beyond its standard rating. You can access this in the monitor"s on-screen display menu. You will need to change the refresh rate in your operating system to match the overclock afterward.
G-SYNC and FreeSync also have to be enabled through your graphics card"s driver settings. These can easily be accessed by right-clicking on your desktop.
Some games and other applications that execute in full-screen mode ignore the system setting for refresh rate and might require you to enable your monitor"s maximum refresh rate through their internal settings.
The refresh rate is the number of times the monitor"s screen refreshes every second. Higher frequencies produce smoother and clearer motion and enable more responsive interaction. It"s most important for video games, but it offers an improvement for almost every type of usage as long as the content or device supplies a matching frame rate to the refresh rate of the display. We test to see the maximum refresh rate the monitor can function at its native resolution, and we also check to see which variable refresh rate formats it supports, as well as the range at which it works.
The recommended refresh rate for an LCD monitor is 60 Hz. If on-screen disturbance occurs, you can set it up to 75 Hz to see if that removes the disturbance.
A 24-inch PC monitor with the ability to update its image 500 times per second will be available soon, Asus and Nvidia announced Tuesday. The monitor should boost desktop monitors from the 360 Hz max native refresh rate they see today while putting a mysterious new spin on an old panel technology.
Aptly named the Asus ROG Swift 500 Hz Gaming Monitor, it manages high refresh rates with lower resolution. The 1920×1080 screen leverages a new take on TN (twisted nematic) panels called E-TN, with the "E" standing for esports. According to Asus, the E-TN panel offers "60 percent better response times than standard TN panels," and in its own announcement, Nvidia claimed the E-TN panel brings "maximum motion and clarity." But neither detailed how the technology differs from regular TN.
Standard TN panels have been becoming less common among PC monitor releases as IPS (in-plane switching) and VA (vertical alignment) panels continue catching up in speed while being known for stronger viewing angles, in the case of IPS, and larger contrast ratios, in the case of VA. Those opting for TN are willing to sacrifice some image quality in the name of speed or, often, lower prices. It"s unclear how much sacrifice E-TN may require (besides a max resolution of 1080p) or how much of a premium it"ll have compared to today"s standard TN monitors.
Today, you can buy 360 Hz monitors, including some that can overclock to 390 Hz, but 500 Hz is a new level. The panel maker behind the monitor wasn"t specifically named, but Nvidia"s announcement made a point to note its work with partner AU Optronics, which we recently showed off in 480 Hz monitors and laptops, with the former coming in the 24-inch TN variation. BOE has also been linked with a 500 Hz panel that uses an oxide TFT (thin-film transistor) active layer rather than the more common silicon TFT active layer.
So who needs the fastest PC monitor yet? According to Nvidia"s announcement, "this benefits every game and gamer, not just competitive games and esports pros." Although, if you prefer a sharper image over the fastest speeds, don"t have a powerful enough system to push 500 fps, or play graphically intensive games where 500 fps isn"t feasible, you won"t fit in that "every games and gamer" category.

Nvidia claimed that when paired with a system that can push 500 frames per second—which, of course, is no short order—you would be able to track movement more easily. In a video Nvidia shared claiming to demonstrate the benefits of 500 Hz, it showed a virtual character moving across the screen on a 144 Hz, 240 Hz, and 500 Hz display, and motion appeared jumpier with the lower refresh rates and framerates.
In Nvidia"s virtual keynote for the Computex conference this week, Jeff Fisher, senior vice president of Nvidia"s GeForce business, said Asus" 500 Hz monitor has the "lowest latency" of any monitor with Nvidia G-Sync. Nvidia also pointed to a system latency challenge it recently conducted with Steam players of various skills levels gaming with 25, 55, and 85 ms latency levels. The challenge led Nvidia to conclude that lower latency "improves your score regardless of aiming skill" and made "difficult aiming tasks possible."
In addition to Nvidia G-Sync, which helps fight screen tears when your Nvidia graphics card"s framerate and the monitor"s refresh rate don"t match up, Asus" 500 Hz monitor will have Nvidia"s latency analyzer, Reflex. Nvidia claimed that playing a game on the monitor that also supports Reflex "can further reduce system latency," which you could then measure with the monitor"s Reflex feature.
The upcoming display also supports Nvidia Vibrance Mode, which is made for gaming and "allows more light to travel through the LCD crystals, giving colors new levels of vibrancy and allowing you to pick out details and highlights that might give away an enemy’s position," Asus claimed.
Neither Asus nor Nvidia shared a release date for the Asus ROG Swift 500 Hz Gaming Monitor. Asus demoed its first 360 Hz monitor in person in January 2020, and those were available later that year; although, as of writing, there doesn"t seem to be in-person demos of the ROG Swift 500 Hz yet.

A significant point is that the phosphors on a CRT screen have their "persistence" designed to support a particular fairly narrow range of refresh rates. The phosphors could be made to have really long persistence (seconds), so there would be no serious flicker down to even maybe a 5 second refresh interval, but then, since the phosphors can only be "turned on" and not "turned off", you wouldn"t be able to see motion much faster than that. (Some early CRT terminals used long-persistence phosphors, with the characters "drawn" on the screen instead of scanned. This didn"t provide very fast "refresh", but it only had to be as good as a 10 CPS Teletype.)
LCDs have the property that they can be turned on or off, at some relatively high rate, and once set one way or the other they have a relatively long persistence, on the order of a second or so. For this reason they can support a wide range of refresh rates.
LCDs are "scanned" via an X-Y matrix of wires, with a pixel at each point where two wires cross. Only one pixel can be manipulated at a time. The voltage on a pixel must be maintained long enough to "charge" the pixel, so that it will hold the charge until refreshed, and all pixels must be visited on each refresh cycle.
And, in addition to the charge time, the liquid inside needs time to mechanically reorient its crystal structure (though, at a physics level, this reorientation is tied at least partially to the "charge" time). Both of these factors place an upper limit on refresh rate.
How many times have you tried to record a video being played on your LED screen with your phone or camera, only to find those annoying lines preventing you from recording the video properly?
Recently, we often have customers ask us about the refresh rate of led screen, most of them are for filming needs, such as XR virtual photography, etc. I would like to take this opportunity to talk about this issue To answer the question of what is the difference between a high refresh rate and a low refresh rate.
Refresh rate and frame rate are very similar. They both stands for the numbers of times a static image is displayed per second. But the difference is that the refresh rate stands for the video signal or display while the frame rate stands for the content itself.
The refresh rate of a LED screen is the number of times in a second that the LED screen hardware draws the data. This is distinct from the measure of frame rate in that the refresh rate for LED screens includes the repeated drawing of identical frames, while frame rate measures how often a video source can feed an entire frame of new data to a display.
The frame rate of video is usually 24, 25 or 30 frames per second, and as long as it is higher than 24 frames per second, it is generally considered smooth by the human eye. With recent technological advances, people can now watch video at 120 fps in movie theaters, on computers, and even on cell phones, so people are now using higher frame rates to shoot video.
Refresh rate can be divided into vertical refresh rate and horizontal refresh rate. The screen refresh rate generally refers to the vertical refresh rate, that is, the number of times the electronic beam repeatedly scanned the image on the LED screen.
In conventional terms, it is the number of times that the LED display screen redraws the image per second. The screen refresh rate is measured in Hertz, usually abbreviated as “Hz”. For example, a screen refresh rate of 1920Hz means that the image is refreshed 1920 times in one second.
What you see on the LED video wall is actually multiple different pictures at rest, and the motion you see is because the LED display is constantly refreshed, giving you the illusion of natural motion.
Because the human eye has a visual dwelling effect, the next picture follows the previous one immediately before the impression in the brain fades, and because these pictures are only slightly different, the static images connect to form a smooth, natural motion as long as the screen refreshes quickly enough.
A higher screen refresh rate is a guarantee of high-quality images and smooth video playback, helping you to better communicate your brand and product messages to your target users and impress them.
Conversely, if the display refresh rate is low, the image transmission of the LED display will become unnatural. There will also be flickering “black scan lines”, torn and trailing images, and “mosaics” or “ghosting” displayed in different colors. Its impact in addition to video, photography, but also because tens of thousands of light bulbs flashing images at the same time, the human eye may produce discomfort when viewing, and even cause eye damage.
A higher led screen refresh rate tells you the ability of a screen’s hardware to reproduce the screen’s content several times per second. It allows the motion of images to be smoother and cleaner in a video, especially in dark scenes when showing fast movements. Other than that, a screen with a higher refresh rate will be more suitable for the content with a more significant number of frames per second.
Typically, a refresh rate of 1920Hz is good enough for most LED displays. And if the LED display needs to display high speed action video, or if the LED display will be filmed by a camera, the LED display needs to have a refresh rate of more than 2550Hz.
The refresh frequency is derived from the different choices of driver chips. When using a common driver chip, the refresh rate for full color is 960Hz, and the refresh rate for single and dual color is 480Hz. when using a dual latching driver chip, the refresh rate is above 1920Hz. When using the HD high level PWM driver chip, the refresh rate is up to 3840Hz or more.
HD high-grade PWM driver chip, ≥ 3840Hz led refresh rate, screen display stable and smooth, no ripple, no lag, no sense of visual flicker, not only can enjoy the quality led screen, and effective protection of vision.
In professional use, it is critical to provide a very high refresh rate. This is especially important for scenes geared towards entertainment, media, sporting events, virtual photography, etc. that need to be captured and will certainly be recorded on video by professional cameras. A refresh rate that is synchronized with the camera recording frequency will make the image look perfect and prevent blinking. Our cameras record video usually at 24, 25,30 or 60fps and we need to keep it in sync with the screen refresh rate as a multiple. If we synchronize the moment of camera recording with the moment of image change, we can avoid the black line of screen change.
LED display refresh rate of not less than 3840Hz, the camera to capture the picture screen stability, can effectively solve the image of the rapid motion process of trailing and blurring, enhance the clarity and contrast of the image, so that the video screen delicate and smooth, long time viewing is not easy to fatigue; with anti-gamma correction technology and point-by-point brightness correction technology, so that the dynamic picture display more realistic and natural, uniform and consistent.
Therefore, with the continuous development, I believe the standard refresh rate of led screen will transition to 3840Hz or more, and then become the industry standard and specification.
One thing we should be aware of is that, unlike grayscale, there is a certain risk of too high a refresh rate. When the refresh rate gets higher, it demands more and more quality of LEDs. If the quality of the LED is not good, it will not be able to withstand the impact of high refresh rates and will be easily damaged. Normally, we should set the refresh rate below the maximum value set at the factory, such as 3840Hz, if the refresh rate is too high, it will affect the life of the LED.
Whether you want to use an indoor or outdoor advertising LED screen for branding, video presentations, broadcasting, or virtual filming, you should always choose an LED display screen that offers a high screen refresh rate and synchronizes with the frame rate recorded by your camera if you want to get high-quality images from the screen, because then the painting will look clear and perfect.
If you are searching for a monitor or any other kind of display hardware, there is going to be a lot of jargon to contend with, but one of your biggest questions is likely to be ‘what is refresh rate?’ As you continue your search, you are going to come across this particular terminology over and over again, and it is important to take the time to learn what it means and what it actually affects.
When reading about monitors or starting to compare the different options, refresh rate is something you are likely to come across quite often. But what is refresh rate and how important is it for determining your choice of display hardware? Does it impact the quality of your picture, and can a low refresh rate contribute to eye strain?
“The number of times a display’s image is repainted or refreshed per second. The refresh rate is expressed in hertz (Hz), so a refresh rate of 75 Hz means the image is refreshed 75 times in a second.”
However, it is important to provide some additional information too. Refresh rate is produced by the monitor itself and not the processor or graphics card. In this sense, it differs from another similar term, which is that of frame rate.
One way to think of it is that these two different performance metrics need to work in tandem. For peak performance, you need a monitor with a high refresh rate and a system that can produce a high frame rate too. If either is not up to standard, the quality of the display may be impacted, and you will not experience the full benefits.
Until recently, 60 Hz was regarded as the standard refresh rate for a monitor, and for some users, that may still be sufficient. However, refresh rates of around 60 Hz are associated with a flicker effect that may contribute to issues like eye strain, making it uncomfortable to stare at the screen for long periods. For this reason, even for fairly basic uses, 75 Hz is now regarded as a better starting point for a computer monitor.
Professional designers, especially those working in VFX, motion design, and 3D animation, deal with heavy workflows that require top speeds and high visual quality. While 60Hz or 75Hz will be sufficient for most jobs, people who develop and test multimedia content or graphics need at least 120Hz or 165Hz to do their creative tasks well, meaning finding a professional creative monitor can really make a difference to your workflow.
The biggest improvement from a high refresh rate would be the motion resolution. No matter how fast the moving images are, higher refresh rates increase the sharpness of the picture quality and remove any image stuttering. This feature allows for almost zero loss of image detail and quality, which is crucial for video editors and animators. So, whether you’re cutting footage or checking a slow-motion B-Roll, every single frame is perfectly crisp and vivid.
Effectively, if you do invest in a monitor with a refresh rate of around those levels, you need to ensure that your graphics card and processor can produce a high frame rate. Only then you can experience noticeable improvements to the picture quality and apparent smoothness of movement.ColorPro’s range of professional monitors are equipped with high refresh rates to ensure your work always looks its best.
For esports or high-definition gaming, you are going to want an even higher refresh rate and 120Hz may be considered a better starting point. As Digital Trends highlights, at this kind of refresh rate, assuming your frame rate is solid, you should even notice improvements in terms of how smooth mouse cursor movements feel.
High refresh rates are critical for fast-paced games as they affect how clear and correct the visuals are onscreen. One key impact is reducing input lag. For the smoothest gameplay, a lag time of under 10.9ms would be ideal and a 120Hz monitor can deliver about 8.33ms. This can be a huge difference-maker, especially for serious gamers in competitive esports.
A higher refresh rate also reduces monitor ghosting and screen tearing. Monitor ghosting is almost like a motion blur, where a previous image continues to appear onscreen on the next frame. And screen tears occur when the monitor shows two different frames simultaneously. In which case, having a high refresh rate of 120Hz will be able to support 120FPS to eliminate any possibility of ghosting and tearing. This means any graphics will appear more fluid on the screen.
Refresh rate is a crucial consideration when buying a computer monitor because it determines how often the display is refreshed. Unlike frame rate, which is produced by the system, the refresh rate is produced by the monitor itself. Nevertheless, the two concepts work side-by-side, and both need to be broadly in line with one another.
It is even more important for those who work in the creative field or are serious gamers. A higher refresh rate eliminates image stutters, monitor ghosts, and screen, which makes for pictures that have higher contrasts and sharper details. Professional creators should look at monitors with at least 165Hz, and esports players will require 120Hz or more.
Having a monitor with high refresh rates will mean nothing if your graphics card is not equipped with high frame rates. Read to find out what is the difference between the two in this article, or explore ViewSonic’s range of monitors equipped with high refresh rates.
When comparing 60 Hz vs 75 Hz refresh rates, the answer is quite clear: 75 Hz is better. A refresh rate measures how many times a screen can update in one second. Higher refresh rates are associated with better video quality, reduced eye strain, and even improved gaming experiences. And while 60 Hz has been the bare minimum for decades, a 75 Hz monitor offers an accessible upgrade.
Refresh rate measures how many times a display can update the image on the screen. Video is actually a series of still images that change so quickly that they give the illusion of movement. The faster these images change, the smoother the video appears to be.
A screen’s refresh rate is measured in hertz (Hz), which is a unit of how many times something occurs in one second. Therefore, a refresh rate of 1 Hz shows a new image on the screen every second. A refresh rate of 75 Hz shows 75 separate images in a single second.
Generally speaking, a higher refresh rate results in smoother and more lifelike video so long as the frames per second match. (Ever wonder how many images per second the eye can process?It turns out it’s up to 500 Hz.)
Measured in frames-per-second (fps), frame rate also describes how many images get displayed on the screen each second. The difference lies in the source: refresh rate is determined by the display while frame rate is determined by the computer’s processors.
To fully take advantage of a monitor’s high refresh rate, it’s important that the computer’s central processing unit (CPU) and graphic processing unit (GPU) are able to produce enough frames per second. And on the other side, a high-performance graphics card would only go to waste if paired with a monitor with a slower refresh rate.
Sometimes more is just more. When it comes to refresh rates, a higher rate results in smoother video, less strain on the eyes, and even improved performance in competitive gaming. Even if that jump is a modest increase from 60 Hz to 75 Hz, there is a noticeable improvement in media quality.
So much of modern work deals with viewing and processing data. A smoother display makes a huge difference both in eye health and quickly understanding what’s on screen. A faster refresh rate makes it a much nicer work experience by reducing motion blur in text, graphics, data, and even your cursor.
Higher refresh rates result in smoother, more realistic on-screen media. More images per second can also significantly reduce motion blur, which can make a huge difference in video quality and gaming experiences.
Clearer and more natural motion on screen can go a long way towards better eye health. In fact, at lower refresh rates you may even start to notice aflicker, which can cause a wide range of vision problems and challenges.
A big part of effective ergonomics – for work and for play – is a high-quality display. A higher refresh rate on your monitor goes a long way towards protecting your eyes. Even a small difference like 60 Hz vs 75 Hz can make a huge difference over time.
Though there aremonitors specializing in gaming performance, it’s not always possible to get a high-end monitor just for entertainment. However, raising the bar by just 15 Hz can make a world of difference in not only game enjoyment but also performance.
Together these three factors can make games way more fun to play and even improve accuracy in high-paced games. But unless it’s a dedicated gaming rig,even hardcore gamers feel high-performance monitors aren’t strictly necessary for anything but games.
When it comes to monitor refresh rates, bigger is definitely better. However, 60 Hz represents a bare minimum while anything over 120 Hz is more appropriate to more demanding users. More modest screens with a 75 Hz refresh rate offer a middle ground.
The best — and easiest — way to know what refresh rates your system can support is by playing games and seeing how they perform. Use a frame rate monitoring utility like Fraps to display your current FPS (frames per second) as you play. Most frame rate monitoring utilities will have the ability to benchmark your average FPS , which keeps track of how your system performs over the course of a gameplay session.
Ideally, you’ll want the game’s frame rate to match the monitor’s refresh rate 1:1 for an ideal experience. For example, your system should be outputting 144 FPS to get the full benefit of a 144Hz monitor.
That said, you can still enjoy a higher refresh rate, even if it doesn’t reach the limits of what your display is capable of. Playing at 110Hz is better than playing at 60Hz, and you can always upgrade your CPU and GPU later to get to 144 FPS.
If your system struggles to run games higher than 60 FPS, it’s unlikely you’ll see much benefit from a high-refresh rate display, but it might be worth investing in one if your PC is capable of producing higher than 60 FPS.
In the event you don’t own the game you’re hoping to play yet, you can test similar titles and extrapolate. Games released in the same year, belonging to the same genre, or built in the same engine oftentimes have relatively similar performance requirements. You can also research other player’s experiences and compare your hardware configuration to theirs to get a sense of what to expect.
What does refresh rate mean, and how does it affect gaming? We explain 144Hz monitors and beyond, and why more hertz isn’t always better (but usually is).
For years, the refresh rate has been the go-to number for gamers when buying a monitor. But what exactly is refresh rate and how does it relate to other aspects of monitor technology, such as panel type and response time? Read on to find out.
The refresh rate of a monitor is the speed (rate) at which the monitor’s image changes (refreshes). The faster the refresh rate, the more times the image can update every second and the smoother the image will look. This number of changes per second is measured in hertz (Hz).
The generally accepted level of refresh rate that leads to a satisfying image depends on the application. Cinemas run at just 24Hz, while the old TV standards of PAL and NTSC ran at 50Hz and 60Hz respectively. A typical PC monitor will have a refresh rate of 60Hz, but the latest gaming displays can reach all the way to 240Hz.
The pursuit of faster refresh rates is crucial for gaming, since it allows the screen to keep up with the rapid movements of a player. For instance, a modern mouse can report its position up to 1000 times a second, while modern PCs can run competitive games such as Counter-Strike: Global Offensive or Overwatch at hundreds of frames per second. Having a monitor that can keep up with all that can potentially give a gamer that crucial split-second advantage.
However, there are diminishing returns. For a long time 144Hz was the de facto standard gaming monitor refresh rate (because it’s 6 x 24Hz) but now we’re seeing 240Hz panels. We’re yet to review such ultra-fast panels, but early verdicts suggest that only the most competitive of gamers will gain an advantage. This compares to the leap from 60Hz to anything over 100Hz, which even fairly casual gamers will notice.
Moreover, once you’ve reached such a level of refresh rate, other factors become more noticeable when it comes to trying to get the most clear image. Factors such as response time and motion blur.
Response time is the time it takes for a pixel to change from one colour to another. Generally measured in milliseconds (ms), it’s directly related to refresh rate in that a monitor can only really refresh its image quickly if the pixels can respond quick enough. A 16ms response time translates to a theoretical maximum of a 60Hz refresh rate 1s/60 = 16.6ms.
Response time is the reason that gaming monitors still use TN LCD panels with poor viewing angles, when most other monitors and LCD screens in phones, tablets and laptops have moved onto better technologies such as IPS and VA. TN can respond as quickly as 1ms, whereas the fastest IPS screens are around 4ms and most are 8ms or longer.
Meanwhile, response time is the big advantage that OLED displays have over LCD panel, and is the reason that many of us are so excited about them eventually being cheap enough to replace LCDs in computer monitors. LCDs work by physically moving tiny crystals embedded in the surface of the screen, and so are relatively slow to respond. OLED displays, on the other hand, are purely electronic, making them several orders of magnitude faster – a typical OLED panel has a response time of just 0.01ms.
Something to keep in mind when looking at monitor response times is there isn’t an accepted standard of measurement. It’s generally measured by a figure called grey-to-grey time, which refers to the time it takes for a pixel to transition from grey to white and back again, rather than all the way from black to white to black, which takes longer. But there isn’t a hard and fast standard that defines this.
As such, you can sometimes end up with situations where the monitor may say it has a 4ms response time, for instance, but it can look far slower than that. Unfortunately, there’s no way to really test for this other than to read reviews by people that have actually used the displays.
One of the effects of having a slow refresh rate or response time is that an image can look blurred. This can happen for a couple of different reasons.
The first is due to response time. With a slow response time, pixels can take a while to fully transition from their previous state to their new one. This can result in there being a trailing, or ghost, image behind the new one. The slower the pixels take to respond, the longer the trail and the less clear your image.
This was a particular problem with the AOC C3583FQ, for instance. It has a fast 160Hz refresh rate that initially, at least, means the image responds quickly. However, the VA LCD panel’s slow response time meant that it had very long, distracting trails that made the display feel nowhere near as responsive as typical TN gaming panels.
The other type of motion blur is eye-tracking motion blur. This is where your brain can perceive an image to be blurry because your eyes naturally track the movement of an image on-screen, but because the image is actually static – even just for a fraction of a second – your eyes end up blurring the image as they pan across it.
This can be reduced by having a faster refresh rate. However, of even more benefit is a technique known as black-frame insertion. This is where a completely blank image is inserted in between each frame, reducing the time it’s displayed for and masking the effect of your eyes tracking the movement. It effectively doubles the refresh rate, but without the need for any extra image information, which is why it works when watching fixed-refresh rate video on TVs too.
How this is achieved depends on the type of screen technology. OLED screens can just turn on and off, but with LCDs it is the backlight that’s turned on and off instead.
The interesting thing about this effect is that it can be just as effective on displays with fast response times. That’s because it’s to do with how long the image is displayed for, not how quickly it can change, which is why it’s still effective even on OLED displays that have super-fast response times.
So are fast refresh rate gaming monitors worth it? Absolutely. If you play fast-paced, competitive games, the responsive feel of a 100Hz+ monitor with a sub 4ms response time is undeniable and can bring a real competitive advantage.
Be honest with yourself, though. If you don’t actually play competitive multi-player games – particularly FPS – then you’re better off prioritising image quality over refresh rate and response time. Indeed, that’s why the likes of the Asus PG279Q and Acer XF270HU have proved so popular: they strike the perfect compromise between all these factors.
Since many gamers now utilize high refresh rate displays, featuring refresh rates ranging from 120 Hz up to 165 Hz, Some manufacturers have begun development to push refresh rates even further. According to TFTCentral, both LG.Display and AU Optronics have stated their goals to create a 480 Hz LCD panel, although no specific production dates have been officially released, LG.Display does currently have its 480 Hz display listed for production in Q4 2022.
Many gamers have been utilizing gaming monitors that offer fast refresh rates ranging from 75 Hz, just 15 Hz above the standard 60 Hz, all the way to 165Hz, increasing the refresh rate by 100 Hz. Many eSports gamers look to have the highest refresh rate possible. This is because having a high refresh rate and fast reaction time can significantly increase your performance in games like Call of Duty or Fortnite, where fast reactions and quick thinking are critical.
While many gamers get a 144 Hz or a 165 Hz gaming monitor, the faster display features a refresh rate of up to 360 Hz but is usually limited in either the resolution or size of the screen. Most 360 Hz refresh rate monitors feature a 24.5" screen size and a 1080p resolution, and this is due to the graphics power required to power the faster refresh rate.
LG.Display is one of the two companies that have stated they plan to develop a 480 Hz display. The company did state that development will begin in 2021, with production beginning in late 2022, which will delay these display"s release onto the eSports and gaming markets. Very little information has been released at this point, although the first option will most likely feature a 24.5" screen size and HDR 400 Support.
The second company to announce its desire to create a 480 Hz refresh rate monitor is AU Optronics which has stated its goal to not only create a 1080p screen with a refresh rate of up to 480 Hz but also create a 4K display with a refresh rate of up to 240 Hz. Sadly AU Optronics has yet to release any official information other than its development goals, meaning we"ll need to wait longer to hear about its high refresh rate and possibly high-resolution monitors.
The component brand, AUO, showcased two prototypes of 480Hz gaming monitors in a YouTube video to coincide with its presence at the Society for Information Display’s Display Week (SID Week) conference, which took place in San Jose, California this week.
One of the proposed displays is a 24-inch FHD PC monitor with a 480Hz refresh rate and a less than 1ms response time. The second is a 16-inch FHD laptop display with a 480Hz refresh rate and a response time of “slightly higher than 1ms.”
Ars Technica correctly notes that this is a TN 1080p panel, meaning the proposed display has traded some image quality to prove that the 480Hz refresh rate can be achieved. However, for showcasing at conferences such as SID Week, perfection is not quite necessary.
Refresh rates common on the market today for PCs and laptops are most commonly anywhere between 60Hz and 240Hz. Many gaming-focused monitors or laptops often vary between 165Hz and 240Hz, even in higher resolutions. There are even a few 360Hz displays on the market, such as the Alienware 25 AW2521H; so it does make sense that the industry is looking to experiment beyond that rate.
Ars Technica noted that AUO works with brands, including Acer, Asus, and MSI, providing them panels for monitors and laptops. These brands could be among those that might experiment first with 480Hz refresh rates in the future.
Industry players must first decide if a 480Hz refresh rate is actually useful. Well, you might expect that e-sports professionals could actually be able to make use of refresh rates that high, but the average PC gamer won’t come anywhere close to producing frame rates that high — nor would they be able to tell the difference.
Gaming PC brands in particular use variable refresh rate technology as a way to maximize system processes while still having a lower base refresh rate. Perhaps brands can implement a variable-refresh rate with a maximum of 480Hz before introducing a PC or laptop with a standard refresh rate that high.
When comparing the performance of two custom gaming PCs, we often look at the frame rates each computer is capable of producing in a certain game at the same resolution and graphics quality. Frame rates are measured in FPS or Frames per Second. Most people know that higher FPS is better, but let’s clear up some common misconceptions with FPS and refresh rates.
First, what is a frame and what determines the frame rate? A frame is a single still image, which is then combined in a rapid slideshow with other still images, each one slightly different, to achieve the illusion of natural motion. The frame rate is how many of these images are displayed in one second. To produce, or render, a new frame your CPU and GPU work together to determine the actions of the AI, the physics, positions, and textures of the objects in the scene to produce an image. Then your GPU cuts this image into pixels at the resolution you set and sends this information to the display. The more powerful your CPU and GPU, the more frames they are able to generate per second.
Your monitor or display is where refresh rates come in. Refresh rate is measured in frequency (Hz) which is the number of times per second your monitor can redraw the screen. A refresh rate of 85Hz means that your display can redraw the entire screen 85 times in one second.
Does that mean that your frame rate is limited by your screen’s refresh rate? No; they are two separate things. Remember that FPS is how many frames your custom gaming PCs is producing or drawing, while the refresh rate is how many times the monitor is refreshing the image on the screen. The refresh rate (Hz) of your monitor does not affect the frame rate (FPS) your GPU will be outputting. However, if your FPS is higher than your refresh rate, your display will not be able to display all of the frames your computer is producing, so although the refresh rate doesn’t technically limit the frame rate, it does effectively set a cap.
It’s also important to remember that even if your gaming PC is capable of generating 90 FPS in your favorite game at your preferred settings, and even if your monitor supports 90Hz, 120Hz or more, you could still be capped by the lower refresh rate capabilities of the ports on your graphics card and display. Read our blog post on DisplayPort vs HDMI vs DVI vs VGA to learn about the pros, cons and limitations of the different types of connections. For example, some gaming monitors feature 120Hz refresh rates, but have HDMI 1.4 and DisplayPort 1.4. This means that you can only take advantage of the 120Hz refresh rate if your use DisplayPort; you’ll be stuck at 60Hz if you use HDMI.
Frame rate is typically used as a gaming benchmark for measuring the performance of hardware, drivers, games and APIs like Vulkan and DirectX. In this case the monitor’s refresh rate doesn’t matter because the frame rate is just used as a number to measure the gaming performance. A higher frame rate is better. However, when you’re actually playing a game, the display’s refresh rate does effectively limit the frame rate – if you have an 80hz display and your computer is capable of outputting 120 FPS, your screen will still only be able to show 80 different images per second.
To prevent screen tearing, you can enable a feature called Vertical Synchronization, or VSync. This tells your GPU to synchronize its actions with the display, which forces it to render and send a new frame when the monitor is ready to redraw the screen. This does limit your framerate exactly to the refresh rate. For example, if your refresh rate is 60Hz, VSync will cap your framerate to 60 FPS. If your GPU is capable of producing higher frame rates than the VSync cap you can take advantage of its leftover capacity to increase the resolution, draw distance, or other graphics quality settings. If your graphics card can’t outpace the refresh rate of your display then enabling VSync won’t help much. You may be able to lock your GPU into a lower frame rate, like 30 FPS, that would match up with your monitor. Common display refresh rates include 120hz, 60hz and 30hz, and there are all divisible by 30 so you won’t get screen tearing, but you may get stutter, as each frame will be on the screen for a couple of cycles.
If your monitor and graphics card both in your customer computer support NVIDIA G-SYNC, you’re in luck. With this technology, a special chip in the display communicates with the graphics card. This lets the monitor vary the refresh rate to match the frame rate of the NVIDIA GTX graphics card, up to the maximum refresh rate of the display. This means that the frames are displayed as soon as they are rendered by the GPU, eliminating screen tearing and reducing stutter for when the frame rate is both higher and lower than the refresh rate of the display. This makes it perfect for situations where the frame rate varies, which happens a lot when gaming. Today, you can even find G-SYNC technology in gaming laptops!
AMD has a similar solution called FreeSync. However, this doesn’t require a proprietary chip in the monitor. Instead, FreeSync relies on the DisplayPort’s Adaptive-Sync specification, which is a royalty-free industry standard. The difference between them is that in G-SYNC, the proprietary module in the monitor handles the work of communication between the devices. In FreeSync, the AMD Radeon driver, and the display firmware handle the communication. AMD has demonstrated that FreeSync can work over HDMI, but it requires custom drivers from AMD and the monitor’s manufacturer. Currently G-SYNC only works with DisplayPort, but that may change. Generally, FreeSync monitors are less expensive than their G-SYNC counterparts, but gamers generally prefer G-SYNC over FreeSync as the latter may cause ghosting, where old images leave behind artifacts. However, this may change as both technologies are relatively new.
