Check the extent to which your monitor can display similar colors while keeping them differentiable. You can create two color patches to do so. The more similar the two colors that can still be differentiated from one another are, the better your monitor can differentiate between the colors. This test is also well suited for making a direct visual comparison between two different monitors.

This test allows you to determine whether your monitor can reproduce text sharply and without any shadows, independently of other influences, such as text smoothing.

Test the monitor’s viewing angle stability. When you increase the viewing angle, the size and shape of the circles displayed should remain almost the same. Slight changes may appear. Less is better.

Use the slide bar to change the logo’s grayscale until the logo blends into the background to the greatest possible extent. The value shown corresponds to your monitor’s gamma value.

This test primarily serves to compare the response times of two monitors. Start by selecting a speed that creates clear streaks on the rectangles. However, you should still be able to clearly follow the rectangles visually. Then vary the distance between the rectangles until the lower edge (streak) of the one on the right no longer overlaps the lower edge of the one on the left. The smaller the distance, the shorter the response time. When comparing several monitors, select the same speed.

DisplayTester makes it possible to test almost every aspect of your device"s LCD/OLED screen. Using Google Cast it is possible to test the display quality of your TV. It is designed to allow full screen testing also on devices with soft keys (hiding the soft keys in ICS and later, immersive mode in KitKat and later).

A video wall is not a one-size-fits-all solution. There are many options to choose from when designing a commercial building video wall display: the size and shape of the digital canvas, what type of content will be displayed and the purpose of the video wall. Operationally, you may focus on desired reliability, maintenance and serviceability of the equipment. Hardware and technology decisions ensure the video wall will deliver both the desired viewing and ownership experience.

One of these choices is deciding between an LCD display or an LED video wall. Continue reading to find out more about the basics, as well as the advantages and disadvantages of each solution.

Most people are familiar with LCD technology, which stands for Liquid Crystal Display. These types of displays have a massive presence in this world, used in living rooms to watch movies, fast-food restaurants to showcase menus, airports to show flight schedules, and everything in between. LCD technology was developed in the 1960s and has been used worldwide as a standard for roughly 20 years. It is a tried-and-true technology that has stood the test of time and will be around for the foreseeable future.

On an LCD screen, the panel is illuminated by a light source and works through reflection or transmission of light. Overall, LCD displays have better viewing angles and less glare than LED screens. This technology was designed to be energy efficient and tends to be lighter in weight.

An LCD video wall is made up of multiple LCD panel monitors mounted on a surface to create a digital canvas, which then work together to create a unified experience. They operate 24/7 at a high brightness and have thin bezels that help create a seamless look when the displays are placed next to one another.

Bezel thickness and the brightness rating are among key attributes to consider for an LCD video wall display. Here is what each of these means and why.

Bezel:Bezel thicknesses for video wall displays are measured in “bezel-to-bezel” thickness.This is the thickness of the bezel when two displays are placed next to one another. Displays can be either large bezel or thin bezel.

Nits:Brightness is measured in Nits. A higher Nit value means the display will be brighter. A brighter display is necessary in a room that sees plenty of direct sunlight, or if the intent is to draw in visitors from far away. With LCD video walls, the price of the hardware goes up as the display size and brightness increase, and the bezel width decreases.

The next item to consider is the type of content that will be displayed on your video wall. LCD displays have high resolution screens — modern 4K displays have over 8 million pixels! This means that the content being displayed is highly detailed and crystal-clear. A viewer could stand less than 1 foot away from the screen and be able to see exactly what is being shown on the screen.

Like previously mentioned with LCD video walls, an important consideration in the decision-making process is the type of content that will be displayed on the video wall. LED video walls suffer from image degradation and pixilation from up close, so fine details will be lost, and text will be illegible. If detail from up close is important, LCD displays are much better suited for that situation.Content examples that are well-suited for an LCD video wall:

Video walls add exciting drama and premium value to showcase spaces. It is an investment that adds a perfect eye-catching solution for a busy lobby, conference room, or any other space.

Video walls are relatively new. But LCD technology has had decades of mainstream adoption, and with that comes both familiarity and lower costs. If those are important to you, then an LCD video wall is likely the right choice.

LED video walls are similar to LCD video walls, but the digital canvas is built using LED panels. Individual LED panels can be anywhere from 12”x12” to 36”x18”, which is much smaller than LCD displays. LED panels have a larger presence in this world than most might think—they are found indoors and outdoors at stadiums, arenas, concert venues, airports, and in use as large digital advertisements in iconic places such as Times Square.

The module is a small rectangular board that contains all the individual LEDs (light-emitting diodes).Unlike LCD, there is no glass or color filter on the LED video wall panels. The individual diodes that are placed on the modules produce both color and light.

One of the most impressive features of LED panels is that they can be combined to create almost any shape, without a bezel interrupting the digital canvas. LED video wall panels can be placed on curved surfaces, 90-degree edges, and other non-standard surfaces. The smaller size of the panels in relation to LCD video wall displays means they can fill more space on a surface—they aren’t limited to standard 46” and 55” sizes as are LCD video wall displays.

The most important factor to consider when scoping LED panels for a video wall is what is referred to as “pixel pitch.” The pixel pitch is effectively the distance between each pixel on the LED panel—a pixel pitch of 6mm means each pixel is spaced 6 millimeters away from the adjacent pixel. The smaller the pixel pitch, the smaller the distance is between each pixel, which means there are more pixels per square inch on the digital canvas.

Multiply the pixel pitch by 10 for the idealviewing experience –For example, a pixel pitch of 4mm would require a viewer to be 12 feet away to decipher any details in the video wall, and 40 feet away for the best viewing experience.

Lastly, pixel pitch impacts the price of the LED video wall more than any other factor. For example, a 2mm pixel pitch LED video wall costs significantly more than its 10mm pixel pitch counterpart.

As is the case with an LCD video wall, an LED video wall will add exciting drama and premium value to showcase spaces. LED panel displays don’t enjoy the benefit of decades of mainstream adoption as do their LCD counterparts. However, the technology curve is increasing their availability and lowering their costs. At this time, an LED video wall will have higher upfront costs compared to an LCD video wall. If cost is the main concern, then an LED video wall system will not likely fit into your budget

An LED video wall would be well-suited and cost-justified if the intent of the video wall is to provide an immersive viewing experience from a further distance. This could be content with lots of movement, animation, imagery, and bright colors to draw viewers into your space or provide a unique experience.

Aside from LED video wall cost, there are other factors to consider which could make an LED video wall system the frontrunner for your project. Here are the advantages and disadvantages to consider:

Limitless shapes and sizes:the smaller size of LED panels allows them to be combined to create unique canvases, including curved, 90-degree edge, and other combinations not possible with LCD displays

Easy maintenance and service; high reliability:LED module replacement takes seconds with little effort; LED panels are rated with a lifetime of 80,000-100,000 hours, depending on the product

Video wall systems come in all shapes and sizes. The components used to create the video wall experience vary widely. Consider variables other than video wall cost when scoping out both the content and the hardware. Because these parts and pieces could make or break the captive viewing experience you’re hoping to achieve, or worse, defeat the entire purpose of that video wall.

The Samsung QN90B QLED is the best TV with an LED panel we"ve tested. It"s an impressive TV with amazing picture quality and a great selection of gaming features. It uses a Mini LED backlight, with way more dimming zones than most LED TVs, which allows for greater control over the local dimming feature for better dark room performance, with less distracting blooming around bright objects. It also gets exceptionally bright, meaning it can handle lots of glare in a bright room.

The Hisense U8H matches the excellent brightness and color performance of much pricier LCD TVs, and its Google TV smart platform is a welcome addition. But it’s available in only three screen sizes.

The Hisense U8H is the best LCD/LED TV for most people because it delivers the performance of a much pricier TV yet starts at under $1,000, for the smallest (55-inch) screen size. This TV utilizes quantum dots, a full-array backlight with mini-LEDs, and a 120 Hz refresh rate to deliver a great-looking 4K HDR image. It’s compatible with every major HDR format. And it’s equipped with two full-bandwidth HDMI 2.1 inputs to support 4K 120 Hz gaming from the newest Xbox and PlayStation consoles. Add in the intuitive, fully featured Google TV smart-TV platform, and the U8H’s price-to-performance ratio is of inarguable value.

Chief among the U8H’s many strengths is its impressive peak brightness. When sending it HDR test patterns, I measured an average brightness of 1,500 nits, with peaks just north of 1,800 nits (a measurement of luminance; see TV features, defined for more info). To put that into perspective, consider that the 65-inch version of our budget 4K TV pick (the TCL 5-Series) typically costs around half as much as the 65-inch U8H but achieves only around 30% to 40% of its brightness. On the other side of the coin, the 65-inch version of our upgrade pick (the Samsung QN90B) costs almost twice as much as the 65-inch U8H, but it achieves only nominally higher brightness. Adequate light output creates convincing highlights and image contrast and (when necessary) combats ambient light from lamps or windows. It is a necessity for any TV worth buying—especially if you hope to watch HDR movies or play HDR games—and the U8H simply outpaces most TVs in its price range (and some in the next price bracket up, too).

That’s not to say the U8H has pixel-precise light control—it’s not an OLED TV, after all—but it does a terrific job most of the time. In fact, in our tests, the U8H bested last year’s upgrade pick, the Samsung QN90A, in certain scenarios: The intro to Guillermo del Toro’s Cabinet of Curiosities on Netflix features the filmmaker against a pitch-black backdrop. Though last year’s QN90A failed to maintain perfect control over dimming elements during this scene (the black backdrop brightened distractingly once a sufficient amount of brighter content appeared on screen), the U8H did not. (For the record, the newer QN90B also passed this test.) The U8H’s mini-LEDs also help the screen look uniformly bright: Although the U8H is still not as good as an OLED TV in this respect, it shows very little indication of being a backlight-driven display, even during tricky scenes with large swaths of dim lighting.

The U8H’s brightness, black-level integrity, and local-dimming abilities make this an excellent TV for watching HDR content. The U8H is capable of playing HDR content in all of the major formats (HDR10, HDR10+, Dolby Vision, and HLG), but when it comes to impressive HDR, what’s under the hood is much more important than format compatibility. The most crucial thing for good HDR is high brightness and deep color saturation, and the U8H’s quantum dots achieve the latter. It’s not as simple as just having quantum dots, however: While many TVs (even the budget options) have quantum dots nowadays, what is often not taken into account is that brightness directly affects color saturation. For example, both the 2022 TCL 6-Series and the Hisense U8H are equipped with quantum dots, mini-LED backlights, and local dimming. But because the U8H is notably brighter than the 6-Series, it also achieves a higher total color volume. During our color-volume testing, the U8H exhibited color ranges at more than 100% of the DCI-P3 color space (the range of color needed to properly display HDR content), and it is capable of roughly 10% more total color volume compared with the 6-Series.

What does this mean in real-world terms? It means that the Hisense U8H truly excels as a modern 4K HDR TV, whether you’re watching the latest episode of Rings of Power or playing Overwatch 2. While watching HDR content side by side on the U8H and on our upgrade pick, the Samsung QN90B, I was truly surprised by how similar they looked at times, given that our upgrade pick is much more expensive. That said, though the U8H achieves impressive results where light output and color volume are concerned, it also exhibited some occasional video processing and upscaling issues (see Flaws but not dealbreakers), which videophiles and AV enthusiasts may take umbrage with. But in general, the picture quality punches well above its weight, metaphorically speaking.

And thanks to Hisense’s inclusion of Filmmaker Mode, it’s easy to rein in the U8H’s brightness abilities for a more-subdued and filmic experience in a darker room. Our measurements revealed that this mode has a very accurate white balance, mostly accurate colors (green is a bit oversaturated, but not egregiously so), and a perfect “dark room” gamma (which controls how quickly the video signal transitions from dark to light). Additionally, the TV’s 120 Hz refresh rate means it can play Blu-ray discs at 24 fps without the judder that’s usually present on TVs with 60 Hz refresh rates.

In terms of design, the Hisense U8H is not as svelte as our upgrade pick, but it’s plenty sturdy and doesn’t look or feel cheap. Two narrow, metal feet jut out from beneath the panel and steadily hold the TV. They can be attached in two separate spots, either closer in toward the middle of the panel or out toward the edges, to account for different-size TV stands. The feet are also equipped with cable organization clasps—a nice touch for keeping your TV stand free of cable clutter. Though the TV is primarily plastic, its bezels are lined with metal strips, providing a bit more durability in the long run. I moved it around my home, and it was no worse for wear, but we’ll know more after doing some long-term testing.

The Hisense U8H has some difficulties with banding, or areas of uneven gradation, where transitions that should appear smooth instead look like “bands” of color (sometimes also called posterization). Like many current 4K HDR TVs, the U8H uses an 8-bit panel rather than a 10-bit panel, which affects the color decoding and color presentation process. This is usually relevant only with HDR video and games. When playing games on the PlayStation 5 and Xbox Series X, I saw a few instances where the content wasn’t rendered correctly and displayed ugly splotches of color on the screen. However, this almost always occurred during static screens (such as a pause menu or loading screen); I rarely spotted it during actual gameplay. Hisense has stated that it would address the problem in a future firmware update, but at the time of writing it was still present. This is a flaw that may give dedicated gamers pause, but we don’t consider it to be a dealbreaker for most people.

I also saw occasional instances of banding with TV shows and movies, though they were few and far between. The U8H isn’t the best at upscaling sub-4K content, so videos with a 1080p or lower resolution looked a little soft. You can get better overall video processing and upscaling by springing for our upgrade pick (this is one reason it’s more expensive, after all).

Finally, like most TVs that use vertical alignment (VA) LCD panels, the U8H has a limited horizontal viewing angle, which may be a bit annoying if you’re hoping to entertain a large crowd. Our upgrade pick uses a special wide-angle technology to address this.

We put the Google Pixel 7 Pro through our rigorous DXOMARK Display test suite to measure its performance across six criteria. In this test summary, we will break down how it fared in a variety of tests and several common use cases.

The Google Pixel 7 Pro achieved an excellent performance nearly across the board, putting it into second place overall as well as in our ultra-premium segment as of this writing. With well-adapted brightness and contrast, the new Google device provides a great HDR10 video experience. Its color is accurate in every use case, and it has especially good readability indoors and in low light.

About DXOMARK Display tests: For scoring and analysis in our smartphone and other display reviews, DXOMARK engineers perform a variety of objective and perceptual tests under controlled lab and real-life conditions.Note that we evaluate display attributes using only the device’s built-in display hardware and its still image (gallery) and video apps at their default settings.(For in-depth information about how we evaluate smartphone and other displays, check out our articles, “How DXOMARK tests display quality” and “A closer look at DXOMARK Display testing.”

The following section gathers key elements of our exhaustive tests and analyses performed in DXOMARK laboratories. Detailed performance evaluations under the form of reports are available upon request. Do not hesitate to contact us.

Readability evaluates how easily and comfortably users can read still content (photos & web) on the display under different real-life conditions. DXOMARK uses its Display Bench to recreate ambient light conditions ranging from total darkness to bright sunlight. In addition to laboratory tests, perceptual analysis is also made in real-life environments.

Google’s latest flagship has good indoor readability, with smooth adaptation to ambient lighting and outstanding uniformity. Readability is preserved when viewed on angle. But while the Pixel 7 Pro’s brightness starts out high under challenging conditions, it quickly drops, which strongly impairs readability.

Tested colors on the Pixel 7 Pro are faithful to the target, ensuring a proper rendering in most lighting conditions. Below are sample results for both the sRGB and DCI-P3 color spaces at 1000 lux.

Our video attribute evaluates the Standard Dynamic Range (SDR) and High Dynamic Range (HDR10) video handling of each device in indoor and low-light conditions. We measure tone mapping, color gamut, brightness and contrast of the display. We perform perceptual analysis against our professional reference monitor (Sony BVM-HX310) to ensure that the rendering respects the artistic intent.

The Pixel 7 Pro has a high score in the Video section, thanks to an HDR10 performance characterized by finely tuned tone mapping, adapted brightness, and accurate colors. With respect to SDR content, however, users might want to boost the brightness to better enjoy their viewing experience.

On some specific content, such as this sunset shot in an HDR10 video, quantization — seen as a clearly demarcated halo around the sun — is visible on both Google phones.

The primary colors are measured both in HDR10 and SDR. The extracted color gamut shows the extent of the color area that the device can render. To respect the artistic intent, the measured gamut should match the master color space of each video.

The motion attribute evaluates the handling of dynamic contents. Frame drops, motion blur, and playback artifacts are scrutinized using games and videos.

The new Google device manages frame drops very well for FHD and UHD videos, although stutters are sometimes visible when playing video games.  In particular, stuttering was noticed when playing the Alto’s Odyssey game that we use in testing. Further, our engineers often noticed long pauses when resuming play of videos downloaded on the Pixel 7 Pro.

These long-exposure photos present the number of frame irregularities in a 30-second video. A good performance shows a regular pattern (either a flat gray image or a pull-down pattern).

Touch is accurate on the Pixel 7 Pro, with good accuracy even on edges and corners; it is reactive, but slightly less so than the Samsung Galaxy S22 Ultra (Snapdragon). The new Google phone feels smooth when browsing the web and when scrolling through photos, but it lacks smoothness compared to the Pixel 6 series when playing video games. In particular, the Pixel 7 Pro is not as smooth as its predecessor, the Pixel 6 Pro, when playing the Asphalt 9 Legends video game, which we use in our testing.

This response time test evaluates precisely the time elapsed between a single touch of the robot on the screen and the displayed action. This test is applied to activities that require a high reactivity, such as gaming.

Evaluating artifacts means checking for the performance, image rendering and motion flaws that can affect the end-user experience. DXOMARK measures precisely the device’s reflectance and the presence of flicker, and assesses the impact of residual aliasing when playing video games, among other characteristics.

Looking for the best video editing monitor? With video resolution, color fidelity, bit rate and dynamic range constantly evolving, you need to make sure you"re viewing and editing your footage on a monitor that can keep up with the recording quality of your camera. In this guide we rank the best monitors, prioritizing key features like color accuracy, resolution and brightness uniformity, so you can be sure you"re getting the very best view of your footage.

High definition digital video is now recorded in two main color standards: Rec. 709, and DCI-P3. Ensure your chosen monitor can display as close to 100% of the colors in these recording standards as possible. DCI-P3 has the wider color gamut (more colors) and therefore you"ll need to splash out on a higher quality display if you want near-full reproduction of this color space.

Dell produces several excellent monitors for video editing, but the U3223QE offers the best value of them all. This 31.5-inch panel can display 100% of the sRGB color space, but more importantly for video, there"s 100% Rec. 709 coverage and 98% DCI-P3 coverage - the latter being exceptional.

Add an excellent, highly adjustable stand, and a USB 3 hub and you really won"t find a better quality monitor for video editing without spending considerably more.

Sure, this screen isn"t exactly "cheap", but if you"re serious about video editing, you need wide color space coverage so you"re able to see as much color as possible in your footage. Seriously cut-price screens just can"t display enough colors for accurate color grading, but with 100% Rec. 709 and an impressive 98% DCI-P3 color coverage, the Dell UltraSharp U2723E comes close to much pricier displays for color accuracy.

It also packs 10-bit color depth and an excellent 2000:1 maximum contrast ratio, all inside a smart case with ‘InfinityEdge’ ultra-thin bezels. Video ports include HDMI, DisplayPort, plus there"s a built-in USB 3.0 hub and 2x USB-C ports, one of which can supply up to 90w of power to an attached laptop.

As we"d expect from a premium IPS-based monitor, the U2723QE"s image quality impresses right out of the box, with excellent color vibrancy, contrast intensity and uniformity, none of which shifts if you change your viewing angle. During our testing we also found Dell"s color space coverage claims to be spot-on, as was the factory-calibrated Delta E color accuracy of <2. Even color and brightness uniformity were top notch.

Built-in reference modes match most of those on the Pro Display XDR, to the point where it’s possible to run them side-by-side with little noticeable difference between the two when producing non-HDR content. The calibration and fine-tuning options to customise those modes are also welcome, enabling precise matching to other screens in use. For SDR content, the Studio Display’s 600 nits of brightness easily outperform the equivalent offerings from others such as LG’s 4k 27” UltraFine screen – and there is constant brightness across the panel with an extremely wide viewing angle.

Like HP"s DreamColor Z31x, this is also a 17:9 aspect ratio panel with a native 4096 x 2160 resolution for displaying Cinema 4K footage. 99% AdobeRGB coverage and 98% DCI-P3 coverage ensure you"re seeing a near-flawless color reproduction of your video and images, and there are preset modes for all common video color space standards.

Curved monitors often use VA (Vertical Alignment) LCD tech, which can"t provide the color, contrast and viewing angle consistency of an IPS (In-Plane Switching) LCD display. But Dell has pulled out all the stops and equipped the U4021QW with a 10-bit curved IPS LCD panel with 178/178-degree viewing angles.

What"s more, where most curved ultrawide screens are based around VA panels - an LCD technology which tends to trail IPS screen tech when it comes to color and contrast consistency - the PD3420Q"s superior IPS LCD panel boasts 178/178-degree viewing angles, a 5ms GtG response time, and it can display 1.07 billion colors.

The 16:9 aspect ratio used to be considered wide in the monitor world, then we got 21:9, and now this, the widest ultrawide monitor on the market, with an eye-popping 32:9 ratio. This is a monitor targeted mainly at gamers, but it also makes sense for videographers.

Keen fans of mathematics may have worked out that the 32:9 ratio makes this screen twice as wide as a 16:9 panel, meaning you could display full width 16:9 footage in one half of the screen, while editing software comfortably on the other side.

Not all monitors really need to be curved, but being a whopping 49-inches wide, the CHG90 really benefits from its 1800R curvature. Video color space coverage isn"t quoted, but 99% sRGB and 92% AdobeRGB from this wide-gamut 10-bit display are respectable figures. Less appealing is the monitor is based around a VA-type panel, which won"t quite have the color and contrast uniformity of an IPS screen. But that"s the trade-off for getting so much screen real estate.

We evaluate a monitor with particular attention given to its core image quality, including brightness, contrast, color vibrancy and accuracy. While this can - and will - be assessed by the experienced eye of our professional reviewer, some manufacturer screen specs can only be definitively judged by an "electronic eye" - a monitor calibrator. Where possible, a calibration device will be placed on the screen to verify its advertised color space coverage, brightness output and consistency, and factory color calibration accuracy. Beyond image quality, we"ll also scrutinise the monitor"s display and data ports to ensure acceptable connectivity, and will give a thorough assessment of build quality, including the range of ergonomic adjustment in its stand. Only then will we determine if a screen is worthy of use by a discerning imaging or video enthusiast.Round up of today"s best deals
