Refresh rate is a number that specifies how many times per second the image on your TV changes. With most TVs it"s 60, though it"s rare you"ll ever see a TV with that number listed. Instead, manufacturers use different technologies, such as

Higher refresh rate claims with numbers like 120, 240 and higher are common, but not always accurate. In fact, no matter what number you see listed with a 4K TV, no 4K TV has a native panel refresh rate higher than 120Hz. As we"ll explain, though, a number higher than 120Hz doesn"t necessarily mean the claim is false.

Effective refresh rate means the TV refreshes its image at a lower rate, but might appear to have similar motion resolution as a TV with an actual higher refresh rate.

Let me start with the terms you"ll see on various TV makers" marketing materials and web sites. Each one calls the TVs motion handling capability something different, and many don"t even mention the term "refresh rate" or use "Hz" at all.

LG"s web site lists the panel"s native refresh rate up front. On TVs that have a 120Hz refresh rate it simply says "120Hz Native," while with 60Hz models it lists "TruMotion 120 (60Hz Native)."

Samsung is better than it used to be about this, albeit not as transparent as LG. The 4K TVs and 8K TVs on its site list a "Motion Rate." This is, generally, twice the native refresh rate. So Motion Rate 240 indicates a native refresh of 120Hz while Motion Rate 120 means a 60Hz refresh. In the least expensive of their TVs, a Motion Rate of 60 means a 60Hz refresh.

For most of its 2021 TVs Sony doesn"t list a number on its website, instead it just says "Motionflow XR." On some, however, it lists a number along with the native refresh: "Motionflow XR 240 (native 60 Hz)" and "Motionflow XR 960 (native 120 Hz)."

Vizio used to list an "Effective Refresh Rate" on its web site, which was just double the native refresh rate. For 2021, however, none of its TVs use that term as far as we could find, and most don"t list any refresh rate spec. The bottom line? All of

For the most effective increase in motion resolution, and compatibility with next-gen gaming consoles" best video output modes, you need a native 120Hz refresh television. That said, it is possible to have some improvement in motion resolution even with a 60Hz TV if it uses some other feature, like backlight scanning or black frame insertion, that improves motion resolution.

So are these higher refresh numbers just another "more is better!" marketing ploy? Not entirely. Higher refresh rates can reduce motion blur in LCDs and OLED TVs.

Interestingly, this blur is largely created by your brain. Basically, your brain notices the motion, and makes assumptions as to where that object (or overall image) is going to be in the next fraction of a second. The problem with LCD and current OLED TVs is that they hold that image there for the full 60th of a second, so your brain actually smears the motion, thinking it should be moving, when in fact it"s just a series of still images.

The motion blur we"re talking about here, despite coming from your brain, is caused by how the television works. This is separate from whatever blur the camera itself creates.

Both of these techniques are what manufacturers use to come up with their "effective refresh rate" numbers. For example, a TV with a 60Hz refresh and a scanning backlight might claim to have an effective refresh rate of 120. A TV with a more elaborate BFI mode, and frame interpolation, might have a claimed effective refresh rate of "540." There"s no transparency in how companies determine their "effective rate" numbers, but there is at least more consistency than there used to be.

It"s also possible these features, when enabled, are bothersome over time. Some people are especially sensitive to a flickering backlight, so you might need to turn these features off. If you"re concerned about that, or notice motion blur, it"s best to find a TV that actually has a 120Hz refresh rate.

The refresh rate (or "vertical refresh rate", "vertical scan rate", terminology originating with the cathode ray tubes) is the number of times per second that a raster-based display device displays a new image. This is independent from frame rate, which describes how many images are stored or generated every second by the device driving the display.

On cathode ray tube (CRT) displays, higher refresh rates produce less flickering, thereby reducing eye strain. In other technologies such as liquid-crystal displays, the refresh rate affects only how often the image can potentially be updated.

Non-raster displays may not have a characteristic refresh rate. Vector displays, for instance, do not trace the entire screen, only the actual lines comprising the displayed image, so refresh speed may differ by the size and complexity of the image data.

Raster-scan CRTs by their nature must refresh the screen, since their phosphors will fade and the image will disappear quickly unless refreshed regularly.

In a CRT, the vertical scan rate is the number of times per second that the electron beam returns to the upper left corner of the screen to begin drawing a new frame.vertical blanking signal generated by the video controller, and is partially limited by the monitor"s maximum horizontal scan rate.

The refresh rate can be calculated from the horizontal scan rate by dividing the scanning frequency by the number of horizontal lines, plus some amount of time to allow for the beam to return to the top. By convention, this is a 1.05x multiplier.1280 × 1024 results in a refresh rate of 96,000 ÷ (1024 × 1.05) ≈ 89 Hz (rounded down).

CRT refresh rates have historically been an important factor in videogame programming. In early videogame systems, the only time available for computation was during the vertical blanking interval, during which the beam is returning to the top corner of the screen and no image is being drawn.screen tearing.

Unlike CRTs, where the image will fade unless refreshed, the pixels of liquid-crystal displays retain their state for as long as power is provided, and consequently there is no intrinsic flicker regardless of refresh rate. However, refresh rate still determines the highest frame rate that can be displayed, and despite there being no actual blanking of the screen, the vertical blanking interval is still a period in each refresh cycle when the screen is not being updated, during which the image data in the host system"s frame buffer can be updated.

On smaller CRT monitors (up to about 15 in or 38 cm), few people notice any discomfort between 60–72 Hz. On larger CRT monitors (17 in or 43 cm or larger), most people experience mild discomfort unless the refresh is set to 72 Hz or higher. A rate of 100 Hz is comfortable at almost any size. However, this does not apply to LCD monitors. The closest equivalent to a refresh rate on an LCD monitor is its frame rate, which is often locked at 60 fps. But this is rarely a problem, because the only part of an LCD monitor that could produce CRT-like flicker—its backlight—typically operates at around a minimum of 200 Hz.

Different operating systems set the default refresh rate differently. Microsoft Windows 95 and Windows 98 (First and Second Editions) set the refresh rate to the highest rate that they believe the display supports. Windows NT-based operating systems, such as Windows 2000 and its descendants Windows XP, Windows Vista and Windows 7, set the default refresh rate to a conservative rate, usually 60 Hz. Some fullscreen applications, including many games, now allow the user to reconfigure the refresh rate before entering fullscreen mode, but most default to a conservative resolution and refresh rate and let you increase the settings in the options.

Old monitors could be damaged if a user set the video card to a refresh rate higher than the highest rate supported by the monitor. Some models of monitors display a notice that the video signal uses an unsupported refresh rate.

Some LCDs support adapting their refresh rate to the current frame rate delivered by the graphics card. Two technologies that allow this are FreeSync and G-Sync.

When LCD shutter glasses are used for stereo 3D displays, the effective refresh rate is halved, because each eye needs a separate picture. For this reason, it is usually recommended to use a display capable of at least 120 Hz, because divided in half this rate is again 60 Hz. Higher refresh rates result in greater image stability, for example 72 Hz non-stereo is 144 Hz stereo, and 90 Hz non-stereo is 180 Hz stereo. Most low-end computer graphics cards and monitors cannot handle these high refresh rates, especially at higher resolutions.

For LCD monitors the pixel brightness changes are much slower than CRT or plasma phosphors. Typically LCD pixel brightness changes are faster when voltage is applied than when voltage is removed, resulting in an asymmetric pixel response time. With 3D shutter glasses this can result in a blurry smearing of the display and poor depth perception, due to the previous image frame not fading to black fast enough as the next frame is drawn.

This gif animation shows a rudimentary comparison of how motion varies with 4Hz, 12Hz, and 24Hz refresh rates. Entire sequence has a frame rate of 24Hz.

The development of televisions in the 1930s was determined by a number of technical limitations. The AC power line frequency was used for the vertical refresh rate for two reasons. The first reason was that the television"s vacuum tube was susceptible to interference from the unit"s power supply, including residual ripple. This could cause drifting horizontal bars (hum bars). Using the same frequency reduced this, and made interference static on the screen and therefore less obtrusive. The second reason was that television studios would use AC lamps, filming at a different frequency would cause strobing.NTSC color coding) and 50 Hz System B/G (almost always used with PAL or SECAM color coding). This accident of chance gave European sets higher resolution, in exchange for lower frame-rates. Compare System M (704 × 480 at 30i) and System B/G (704 × 576 at 25i). However, the lower refresh rate of 50 Hz introduces more flicker, so sets that use digital technology to double the refresh rate to 100 Hz are now very popular. (see Broadcast television systems)

Similar to some computer monitors and some DVDs, analog television systems use interlace, which decreases the apparent flicker by painting first the odd lines and then the even lines (these are known as fields). This doubles the refresh rate, compared to a progressive scan image at the same frame rate. This works perfectly for video cameras, where each field results from a separate exposure – the effective frame rate doubles, there are now 50 rather than 25 exposures per second. The dynamics of a CRT are ideally suited to this approach, fast scenes will benefit from the 50 Hz refresh, the earlier field will have largely decayed away when the new field is written, and static images will benefit from improved resolution as both fields will be integrated by the eye. Modern CRT-based televisions may be made flicker-free in the form of 100 Hz technology.

Many high-end LCD televisions now have a 120 or 240 Hz (current and former NTSC countries) or 100 or 200 Hz (PAL/SECAM countries) refresh rate. The rate of 120 was chosen as the least common multiple of 24 fps (cinema) and 30 fps (NTSC TV), and allows for less distortion when movies are viewed due to the elimination of telecine (3:2 pulldown). For PAL at 25 fps, 100 or 200 Hz is used as a fractional compromise of the least common multiple of 600 (24 × 25). These higher refresh rates are most effective from a 24p-source video output (e.g. Blu-ray Disc), and/or scenes of fast motion.

As movies are usually filmed at a rate of 24 frames per second, while television sets operate at different rates, some conversion is necessary. Different techniques exist to give the viewer an optimal experience.

The combination of content production, playback device, and display device processing may also give artifacts that are unnecessary. A display device producing a fixed 60 fps rate cannot display a 24 fps movie at an even, judder-free rate. Usually, a 3:2 pulldown is used, giving a slight uneven movement.

While common multisync CRT computer monitors have been capable of running at even multiples of 24 Hz since the early 1990s, recent "120 Hz" LCDs have been produced for the purpose of having smoother, more fluid motion, depending upon the source material, and any subsequent processing done to the signal. In the case of material shot on video, improvements in smoothness just from having a higher refresh rate may be barely noticeable.

In the case of filmed material, as 120 is an even multiple of 24, it is possible to present a 24 fps sequence without judder on a well-designed 120 Hz display (i.e., so-called 5-5 pulldown). If the 120 Hz rate is produced by frame-doubling a 60 fps 3:2 pulldown signal, the uneven motion could still be visible (i.e., so-called 6-4 pulldown).

Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

Sony produces and sells commercial MicroLED displays called CLEDIS (Crystal-LED Integrated Displays, also called Canvas-LED) in small quantities.video walls.

LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

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.

The brand is using this tech combined with "high refresh rate, high resolution, low power oxide display technology" to make this 500Hz display possible.

We"re not sure exactly what this means but it could point to an oxide TFT screen of some description. Possibly related to the IGZO technology that was all the rage a few years back.

For CRT displays, the electron beam is scanned point by point from the upper left corner of the screen to the right, forming a horizontal line: "knife up to the right end" and then back to the left end of the next horizontal line, repeating the process above: when the beam completes scanning at the lower right corner, a frame is formed. Thereafter, the electron beam returns to the starting point in the upper left corner to start the next scan. This method is also known as a progressive scan display. The completion of a frame of the time spent on the countdown called vertical scan frequency, also known as the refresh frequency (i.e. field frequency), such as 60Hz, 75Hz, etc. The greater the refresh rate, the greater the screen. The greater the refresh rate, the less likely the screen flicker, if the refresh rate is above 75Hz, the user is not easy to feel the screen flicker.

For the LCD, because of its working principle and CRT display is completely different, LCD is not like CRT display to launch the electron beam, there is no need to set the refresh rate indicators, but the output signal of the graphics card and the refresh rate of the signal, so LCD manufacturers in order to compatible with the graphics card, had to set a refresh rate indicators.

The graphics card can be compared to the human brain, the LCD compared to the human hands and feet, LCD is very mechanical, the graphics card let it do what it does, the graphics card output a 60Hz refresh rate signal, LCD will also do the same. In fact, the LCD refresh is not a single pixel, but the whole screen, this refresh is actually meaningless, even if the LCD refresh rate is working at 1 Hz also does not matter, the picture and work at 60Hz are the same. This is also why the LCD refresh rate is king in 60Hz and works in 75Hz feel the same reason. Perhaps only when CRTs are completely obsolete, LCDs and graphics cards will have no refresh rate specifications.

Some may ask: most of the LCD at 60Hz refresh rate can achieve the best picture quality, why not lock the refresh rate at 60Hz, but to have 60 ~ 75Hz selection range? In fact, this is related to the use of flexibility and compatibility issues. As the LCD trying to replace the CRT monitor market position, and most of today"s graphics cards are still designed to CRT monitors, higher flexibility and compatibility will help LCD cut into and quickly capture the market.

There may be some people who will ask: why my LCD refresh rate when working at 60Hz and working at 75Hz when the picture will be very different? The LCD is only in the analog refresh, but it is also true that at 15 times per second to refresh the entire screen, when the LCD can not withstand the 75Hz refresh rate signal, the picture will be blurred. At this point, you should set the graphics card"s refresh rate at 60Hz, a refresh rate that any LCD can withstand.

60Hz refresh rate and 75Hz refresh rate is no difference, why must the refresh rate set high? In fact, the important indicator of LCD is the response time rather than the refresh rate, LCD manufacturer"s propaganda, all say how fast the response time, not how high the refresh rate. Therefore, the refresh rate is not LCD"s main performance indicators.

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.

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.

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.

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.

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.

But there"s one area where details aren"t just cloudy, they"re sometimes downright dishonest, and that"s refresh rates. This simple specification should be an easily understood number, but for several reasons it"s not. It"s not even information that"s easily found, in many cases.

Here"s the low down on what refresh rates are and why they"re important, why TV makers bend the truth, and how you can spot the lie and get the straight info to make a more informed TV purchase.

Expressed in Hertz (Hz), a TV"s actual refresh rate tells you how many times per second a new frame or image can be put up on screen. The human eye starts stitching these images together to create the illusion of smooth motion at rates as low as 24 frames per second, the frame rate traditionally used in film and movies.

Most TVs today offer one of two refresh rates: 60 Hz, which refreshes the display image 60 times per second, and 120 Hz, which refreshes 120 times per second. That 120Hz is actually the better of the two, since fast moving objects, like a slap shot in hockey, or a pass thrown in football, may look a little blurry or choppy, depending upon how the TV handles motion smoothing.

But there"s a difference between the display"s refresh rate (measured in Hz) and the source content frame rate (measured in frames per second or fps). When the refresh rate and the signal rate match, it"s perfect, and you"ll be seeing exactly what the creator intended. If there"s a mismatch, however, the TV will need to apply some video processing techniques to display content properly.

For a very long time, 30fps was the standard, and it"s still a common refresh rate for broadcast TV and older media like DVD and 1080p Blu-ray. But newer media often takes advantage of the newer capabilities to offer higher frame rates better suited to your TV. Gaming in particular has adopted higher frame rates, with the latest consoles offering 60Hz and 120Hz gameplay.

That"s great if you"re selling 120Hz TVs, but less so if you want to compete against those models with a 60Hz display. However, with the processing the TVs already have to do to match source frame rates to display refresh rates, TV manufacturers saw an opportunity to muddy the waters.

There are some very sophisticated approaches to this, but here"s the simple version: TV makers have figured out that they can mimic higher frame rates by adding an extra flicker. By pulsing the backlight on and off in between those 60 refreshes, the alternating pattern of new frames and blinked light provides the illusion of a higher frame rate… sort of.

As a result, you"ll often see TV specs list something called the "effective" refresh rate, which is double what the TV"s panel can actually do. Some brands will use different terminology, but the underlying reality is the same – there"s a difference between the actual refresh rate of the TV display panel and what you"re told in the product specs and marketing materials.

What that really means is that manufacturers can use that light pulsing trick to claim a higher number than the TV actually supports. If you play 120Hz content on a 60Hz display, but bump the effective rate up by flickering the backlight, it won"t magically display all 120 frames of content each second. Instead it will display 60, dropping half of the frames to match the actual refresh rate that the display can handle.

TVs will also use heavy handed motion smoothing techniques to give the illusion of smoothness that a higher frame rate would impart. It is also sometimes called the Soap Opera Effect, because it makes everything look a little blurry or smeared. (Learn how to turn it off in our guide to the 5 TV settings you should change now.)

The first red flag to watch for is "effective rate" when discussing frame rates. As a rule, the effective rate will be double what the panel can physically display, so the actual refresh rate is half that number: an effective rate of 240Hz is really 120Hz, and effective rate of 120Hz is really 60Hz, and so on.

Unfortunately, that particular spec may not always be easy to find. In addition to hiding behind the terms listed above, many times a TV"s refresh won"t even be listed on the manufacturer"s product page. Some will omit that specification altogether, while others will simply leave it blank.

The good news is that we"re watching out for you. We include the real refresh rate in the specs of every TV we review – whether it"s dug up from less accessible material, confirmed by a customer service tech or PR rep, or tested ourselves – so that you have the correct information for any TV we recommend.

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.

Even though we don"t see it, our TV is constantly refreshing itself every second. A refresh rate defines how many times per second it draws a new image on the screen, and it"s written out in Hertz (Hz). A 60Hz refresh rate means that the screen is refreshing itself 60 times every second, and at 120Hz, it"s refreshing itself 120 times every second. This is different from frame rate, which is how many times per second the source sends a new frame. So if you have a source that"s displaying 60 frames per second, you always want your TV to be refreshing itself 60 times/second so that the refresh and frame rate match up, otherwise motion may look blurry.

The refresh rate affects motion handling; the more times the display can draw a new image the better it is for fast-moving content. Modern TVs either have a 60Hz or 120Hz refresh rate. Most high-end TVs have a 120Hz refresh rate, but it doesn"t mean they"re inherently better at motion handling either. The response time determines how good motion looks; a quick response time means that motion looks clear, while a TV with a slow response time leads to motion blur. Response time and refresh rate are indirectly related as a 120Hz panel is expected to have a better response time than a 60Hz panel, but it"s not a guarantee.

Since not all content will automatically have the same frame rate as your TV"s refresh rate, there are also ways a TV increases the frame rate to match up with the refresh rate, improving the appearance of motion.

A 60 fps video played on a 120Hz TV should look almost identical to the same content played on a 60Hz TV. In a case like this, the TV either adjusts itself to match the refresh rate of the source, which effectively turns it into a 60Hz TV, or it simply doubles every frame.

As you can see from the picture above, a TV with a higher refresh rate doesn"t produce less motion blur. Since both of these TVs have a very similar response time, 60 fps content results in an almost identical picture.

While a 120Hz TV doesn"t inherently produce better motion, it can provide a few advantages over standard 60Hz TVs. One of the most important advantages is the ability to play back content that is meant to be displayed at 24 fps, which is often found in movies. Most TVs can simply lower their own refresh rate to 24Hz when the content is 24 fps, but some sources, such as Chromecast, output video at 60 fps, even if the content is 24 fps. This means that the TV"s refresh rate remains at 60Hz, and motion won"t appear smooth, which is an effect called judder. A 60Hz TV has trouble removing 24 fps judder because 60 isn"t a multiple of 24. To display this type of content, a technique known as a "3:2 pulldown" is used. Basically, 12 of the 24 frames repeat three times, while the other 12 repeat twice, totaling 60 frames. Not everybody notices this, but it causes some scenes, notably panning shots, to appear juddery. However, 120Hz TVs have an advantage here because they can simply display each frame five times since 120 is a multiple of 24.

There are a few sources that display 120 fps, such as the Xbox Series X or the PS5, and having a 120Hz TV helps display this content at its max frame rate. While it"s rare to find content other than games with this frame rate, displaying 120 fps has a significant impact on the perceived motion. As you can see in the picture below, content looks much smoother at 120 fps than at 60 fps on a 120Hz TV.

Another place where 120Hz is useful is if you enjoy the motion interpolation feature found on TVs (also known as the Soap Opera Effect). It allows the TV to generate frames between existing ones, increasing the frame rate to match up to the refresh rate. Most TVs have this feature; a 60Hz TV can interpolate 30 fps content, while a 120Hz TV can interpolate 30 and 60 fps content. This is why a 120Hz TV is an advantage over 60Hz since it can interpolate more types of content.

There are other ways to produce a similarly clear image as a 120Hz refresh rate. Many TVs these days have a feature called Black Frame Insertion. Essentially, the TV displays a black screen between each frame, which most people can"t see, but it can also make the screen dimmer. On most LED TVs, this is achieved by adjusting the flicker frequency of the backlight, which results in the backlight being turned off for half the frame. On OLED TVs, which don"t have a backlight, this is done by inserting a black frame in-between each frame.

A TV is only as good as the content you are playing, and unfortunately, very little 120 fps content actually exists. With the new HDMI 2.1 standard, gaming consoles like the Xbox Series X and PS5 support 120 fps, but there isn"t much online content available at such a high frame rate. We"ve compiled a couple of lists of common entertainment sources as well as their respective refresh rates.

A source"s frame rate isn"t always constant, especially in games. It may drop and if that happens, it can lead to screen tearing because the frame rate of the game and the refresh rate of your TV don"t match up. There"s a feature called variable refresh rate (VRR) that aims to match the refresh and frame rate on-the-go, so if the frame rate of the game drops, the TV automatically lowers its refresh rate as well. This is only possible if both the TV and the source support VRR.

TV companies will often market their refresh rates in ways to make it seem like it"s higher than it actually is. A company like Samsung uses the term "Motion Rate"; the Motion Rate on a 60Hz TV is 120, while a 120Hz model has a Motion Rate of 240; they effectively double the refresh rate to come up with this number, and there"s no real explanation as to why it"s marketed like that. LG uses "TruMotion", Vizio has "Effective Refresh Rate", and Sony has two terms: "MotionFlow XR" and "X-Motion Clarity". These marketing numbers don"t really mean anything, and you need to check the TV"s specs to find the real refresh rate.

LCD TVs are lit by LED lights, and most TVs use Pulse Width Modulation (PWM) to dim the backlight. What this means is that the backlight turns itself off every few seconds, so it doesn"t get too bright. It"s not visible to the human eye because of how fast the frequency is. Flicker frequency, like refresh rate, is measured in Hz because we want to know how many times it flickers every second.

If the flicker frequency doesn"t match up with the refresh or frame rates, it can create some image duplication. As you can see in the images below, motion on the LG UN8500 has image duplication because its backlight flickers at 120Hz; this is double the 60 fps source. However, the Sony X800H has a flicker-free backlight, so there"s no image duplication - the motion blur is caused by a slower response time.

A refresh rate defines how often the screen refreshes itself every second. Although we can"t see it, the TV draws a new image from the source every few milliseconds. Generally, a higher refresh rate TV results in better motion handling, but it"s not always the case as there are other factors that come into play with motion. It"s important that your source"s frame rate and the TV"s refresh rate each match in order to create smooth, stutter-free motion. For most people, a TV with a 60Hz refresh rate is good enough since there isn"t much 4k content that goes past 60 fps. However, 120Hz TVs with HDMI 2.1 support are beneficial to gamers as they allow for higher frame rates.

60 Hz and 120 Hz HD LCD TV, here 60Hz and 120Hz denote the refreshing rate of the screen. Before finding the difference between 60Hz and 120 Hz LCD TV, it is pertinent to know what is 60 Hz or 120 Hz in context to LCD TV. These are actually refresh rates of a TV which indicate how many times per second an image is refreshed on the screen. It is interesting to see why manufacturers would attempt to increase refresh rate if there was no problem with 60 Hz. Plasma TV manufacturers never talk of refresh rates, it is only in the context of LCD TV’s that refresh rates come into play. The problem in LCD TV is that of motion lag, which results when the images on the screen are moving quickly. The other problem, known as judding takes place as LCD has a hard time displaying a moving image. This results from a combination of internal processing chips and the response rate of the TV.

To overcome the problems of Motion lag and Judding, LCD TV manufacturers have found a solution in increasing the refresh rate from 60 Hz to 120 Hz. 120 Hz refresh rate is being offered by LCD manufacturers on premium sets. This fast refreshment of the image cuts down on motion induced effects. Faster refresh rate reduces both motion lag and judder. Though refreshing images at a faster rate is a good thing, it tends to give the content a plastic look which is not visually very appealing. This is why it is suggested to watch sports programs at 120 Hz but to watch serials and news broadcasting at a slower refresh rate of 60 Hz. TV manufacturers also realize this and this is why they are offering the option to the viewer to switch the faster refresh rate off and to go back to 60 Hz. This has become a standard feature in all latest high end LCD TV’s where viewers are getting the option to turn off high refresh rate of the TV.

Before buying a new LCD, it is worthwhile to see the specifications of the TV in this regard. However, most people are not able to distinguish any noticeable difference in 60 Hz and 120 Hz rate. This is because fast moving i
