IPS (In-Plane Switching) technology highlights the performance of liquid crystal displays. Response times are shortened, color reproduction is improved, and users can now view the screen at virtually any angle.

Gold Privacy Filter keeps confidential information private when working in public places. It is great for high-traffic areas such as airports, airplanes, commuter trains, coffee shops and other public places. You see your laptop screen with incredibly crisp image clarity while visual hackers with side views outside the 60-degree viewing angle see a vivid golden shield. Proprietary gold effect provides premium privacy with a glossy finish. Filter reduces 35 percent of blue light transmission from the display. It is reversible between vibrant gold and a glossy black screen. Filter is designed to fit wide-screen monitors with a diagonally measured, 21.5" viewing screen and a 16:9 aspect ratio. Actual filter dimensions are 18-3/4" wide x 10-9/16" high (477mm x 268mm). It includes your choice of two easy-to-use attachment methods. Lightweight, thin, frameless design protects display from dirt, debris and scratches. It cleans easily with a soft cloth and water.

The Asus ProArt Display PA278CV has a great-looking screen with good enough color accuracy for most people and all the ports you need to hook up desktop or laptop PCs. The PA278CV’s stand can tilt, swivel, and pivot the screen and raise and lower its height, its USB-C port can provide enough power to charge most 13-inch laptops, and it comes with a three-year warranty and a good dead-pixel policy. Its QHD resolution (2560×1440) means it isn’t as sharp as a 4K screen, but it’s also hundreds of dollars cheaper than comparable 4K monitors.

The Dell S2722QC is a 3840×2160 display that’s great for anyone who watches 4K content or casually edits photos or video. However, if most of your time is spent on general office work or browsing the internet, you don’t really need to spend the extra cash. The S2722QC has a USB-C port with 65 watts of charging, so it can power most laptops except higher-end devices like the Dell XPS 15-inch or the 16-inch MacBook Pros (which are picks in our guide to the best laptops for video and photo editing).

Yes, matte screens objectively don’t look as good as glossy. But that’s in a highly controlled environment. In the real world, matte monitor surfaces are the only practical and rational way to go.

Matte monitors employ plastic surfaces made of different polymers that undergo an etching process. Either chemical or mechanical, the etching creates an enormous number of grooves or indentations in the screen surface. These serve to reduce reflectivity by scattering light that hits the monitor. While some minor glare may still occur, it never even comes close to the full-on reflections you have with glossy displays.

But a screen that rejects light invariably also blocks light. While glossy screens allow whatever the display shows to come through nearly unfiltered, matte screens block much more of the monitor’s light output. In essence, with matte screens you get less image illumination, or just less image. Some minor details may be diminished, contrast gets lowered, and colors don’t appear as alive as with a glossy screen.

But your poor eyes also don’t need to put up with stressful reflections and tiresome glare. Nor do you need to fear touching the screen, as matte displays don’t grab fingerprints as readily as glossy screens. Thus, for monitors matte makes the better option. You don’t need to worry about placing a lamp on your work or gaming station, because reflections won’t be an issue. You don’t have to think ten times before opening the curtains and letting some light in. With matte screens, light isn’t your enemy.

Unlike TVs, for monitors matte makes for an absolutely obvious choice, especially since modern monitors continue to add brightness. While even five years ago a 300-nit monitor was good, today you easily get 500-1000-nit panels that meet DisplayHDR 400 and DisplayHDR 1000 requirements. While monitors get brighter, matte materials stay the same and so in effect more light shines through the anti-glare protection. Simply put, image quality on matte monitors keeps improving. You’d be hard pressed to tell the difference in most cases.

Have you ever properly checked the display quality of the LCD you habitually use? Very often people become aware of previously unnoticed problems in display quality when they run a check using test patterns and so on. This time we are going to talk about the basic points used to assess LCD display quality, and show you a simple way to test it.

Below is the translation from the Japanese of the ITmedia article "The difference in image quality is perfectly obvious! – Let"s check the LCD"s monitor" published April 22, 2010. Copyright 2011 ITmedia Inc. All Rights Reserved.

That"s right. The answer is "LCD" (it is displayed if you drag the space between the brackets). We assume that probably many users could read the letters concealed in the squares.

This time the answer is "EIZO" (it is displayed if you drag the space between the brackets). Depending on the lighting or the user"s environment it may be hard to make out but, if you can read these four letters, the display quality, or more accurately the still image gradation expression, of your LCD is extremely high.

Let"s get down to details then. "Image quality" is the top priority of the LCD, of course. However, recently LCD prices are fiercely competitive and there are surprisingly few products that insist on high image quality and performance. It may be nice to be able to get hold of a wide-screen monitor with full HD (1920 × 1080 dot) resolution or higher fairly cheaply, but it cannot be denied that such LCDs tend not to place too much importance on display quality.

On the other hand, the increasing opportunities to enjoy things like HD videos and games, and high resolution digital photographs on the computer make LCD display quality even more important. As far as possible it"s best to use an LCD with excellent display quality in order to fully enjoy the charms of the visual content.

Even so, perhaps you think that there can"t really be that much wrong with the LCDs that so many people are using at the moment. Here we would like to show you a simple method to check LCD display quality. You can get a good idea of whether the basic display quality is good or bad just by looking at how some simple test images are displayed, just like in the introductory quiz. First of all, we would like you to get a sense of how important it is that "image data can be properly displayed" by checking the display of the LCD that you currently use, (that"s right, the one you are using to view this page!).

Before starting your visual check of the display quality, please return to your LCD"s setting to default, and select Adobe RGB or sRGB as the image quality mode. If these modes are not available it is fine to set the color temperature to 6500K and gamma to 2.2. If you cannot adjust the color temperature and gamma, simply adjust the brightness and contrast so that they are easier to discern. Of course, if it"s an LCD environment that has been color calibrated it"s OK to leave it as it is.

The average LCD takes some time for the monitor to stabilize after it is switched on so, after start up, please wait at least 30 minutes or so before doing the test. (Most EIZO monitors are an exception to this as they are equipped with our proprietary dimming function and the monitor stabilizes in a short time after start up.)

We would also like you to adjust the monitor stand so that things like the room"s lighting are not reflected on the screen. You have to be particularly careful with products that have a glare (glossy) type screen as they are highly reflective. Visual assessment is impeded when ambient light is reflected. It will be much easier to make an assessment if you turn off the room lights at night and exclude as much ambient light as possible. This applies for both glare and non-glare (matte) types.

The surface treatment of an LCD makes a difference to the background reflection. Glare panels impede the surface diffusion of backlight, which does make it easier to achieve high color purity, but also makes distinct reflections of the user or lighting much more likely (photo on the left).

For your reference, we ran a test on an EIZO 24.1-inch wide-screen LCD, the FlexScan SX2462W, for this article. The FlexScan SX series comes with a number of high image quality functions and boasts top class display quality as a general-purpose LCD intended for a computer.

When we displayed the quiz images (the more difficult ones, of course) on the FlexScan SX2462W, the four letters appeared faintly when we stared closely at the screen and we could read what they said. This indicates the high image quality level.

When checking the display quality of an LCD it is comparatively easy to understand the gradation expression capability by a visual check. Let"s display color and monochrome gradation images and check whether the entire image is smoothly reproduced. If there is a problem with the gradation expression it produces things like blocked-up shadows in dark areas and blown-out highlights in light areas, banding (vertical or horizontal stripes) in the middle gradations, and color cast, so you should check for problems like these.

Test images of color / monochrome gradations are shown below. Each test image is prepared for three resolution levels (1280 × 800 dots / 1680 × 1050 dots / 1920 × 1200 dots). When you click on an image it is displayed in that actual resolution. We would like you to download the images in the resolution which matches that of your current LCD. Gradation expression can vary according to whether the image is viewed horizontally or vertically, so it will be more effective if you rotate these images and view them vertically as well.

A gradation pattern where the colors red, green, blue, cyan, magenta and yellow go through 64 gradients as they change to white or black. Each color bar is divided into 64 rectangular blocks. With this many gradients we expect that many LCDs will find it hard to make distinctions in the dark areas or the areas that are close to primary colors.

A smooth gradation pattern where the colors red, green, blue, cyan, magenta and yellow go through 256 gradients as they change to white or black. At this level of difficulty you cannot distinguish between adjoining colors from a distance but, if you have an LCD with excellent gradation expression, if you look closely you should be able to see that each color is divided into thin rectangular blocks.

On an average LCD gradations of gray that are close to black tend to appear as blocked-up shadows (gradations of gray that are close to white are displayed comparatively accurately). If your LCD"s OSD menu allows you to adjust the contrast, please try gradually turning down the contrast. Turning down the contrast often makes it possible to see gradations that had been subject to blocked-up shadows or blown-out highlights.

Probably most LCDs will be able to detect some degree of banding and color cast in the middle gradations. Banding in the middle gradations is tone jump (Missing gradations) and, along with color cast, means that the RGB gamma curves are unequal. Unlike blocked-up shadows or blown-out highlights, this is an area that it is hard to improve with adjustments made by the user.

When there is a problem with the gradation expression, the original colors of the content being displayed cannot be reproduced. If you look carefully at displays like video, games or photographs you can probably see or sense things like a lack of depth in the coloration, unnatural color shifts in the middle gradations or displays blanked out with large blocked-up shadows. Of course, it is very hard to use such monitors for things where color reproduction such as photo retouching or graphics work.

When we looked at these test images on the FlexScan SX2462W, in the smooth gradation there was blocked-up shadows right next to the black but we could distinguish differences in gradations of gray until very close to the black area. When it comes to such subtle gradation distinctions the brightness of the room and the adaptability of the eye come into play, so the range that is visible will vary according to the environment and the individual. The gradation expression was excellent, with almost no blown-out highlights in light areas, middle gradation banding or color cast.

We have talked about ways to check gradation expression. We think that it was comparatively easy to understand about blocked-up shadows in dark areas, blown-out highlights in light areas and banding in middle gradations. However, it is hard to distinguish whether a gradation is being cast with unnecessary color so we would like to add a little more about this.

The answer is "The far right" (it is displayed if you drag the space between the brackets). If the other grays looked correct, color may not be being correctly recognized for a variety of reasons, such as the lighting environment or the LCD settings.

For example, when the room is lit with standard household incandescent lights white and gray look reddish, while fluorescent lights can make them greenish (which is why there is some lighting that is made to conform to color evaluations). What is more, white and gray can have a reddish tinge when the monitor has been set to a low color temperature, while a high setting can give them a bluish tinge. Thus it often happens that the gray in visual data does not look like a true gray.

The orange in the center of each square is in fact exactly the same color in each case (600 × 200 dots). However, when the surrounding saturation is high (red) the orange seems to have a low saturation, but when the surrounding color has a low saturation (green) the orange seems to have a high saturation, doesn"t it? This is known as "chroma contrast"

Now let"s assess the gradation expression with some slightly different test images. Below are color patterns with a spread of pale colors in gradations close to the dark range and the light range. They are arranged so that a distinction cannot be made between adjoining colors on an LCD with insufficient gradation expression.

We expect that you could roughly get the whole picture in the gradation patterns on the previous page, but in the patterns this time some parts that cannot be seen may have appeared in some cases. As we mentioned earlier, LCDs tend to display gradations close to black as a blocked-up shadows, and color patterns that are close to black are particularly hard to distinguish.

Since there are some parts that cannot be seen, the possibility arises subtle skin colors and tones cannot be accurately recognized when doing things like retouching photographs, though the misrecognition will vary according to the user"s eyesight. People who place importance on color reproduction should probably bear this in mind when they think about replacing their LCD or buying an extra one.

Incidentally, when we checked the FlexScan SX2462W with these tests we could distinguish everything in both the close to white and the close to black patterns. As well as no blown-out highlights or blocked-up shadows, we saw no unnatural color casts.

Every LCD has some degree of brightness and chromaticity variation, but there are many products where the variations become more obvious when the brightness is lowered. A comparison of the brightness and chromaticity variation of a number of LCDs reveals that there is a fairly large difference between products, so this is a point to bear in mind.

If you actually try this test you may be surprised to find more variation than you expected when gray or a near-white pale color is displayed. Generally speaking, the center of an LCD screen is the brightest and it gradually gets darker towards the edges. This is no problem if there is not a big difference in brightness between the central and peripheral areas, but there are some products where this difference is very striking.

Incidentally, this test is also an effective way to test the LCD for dot defects (normal lighting / unlit room). We would like you to check the black display in a darkened environment, for example by switching off all the room lights at night. Although you probably saw the whole screen as uniformly black in a light environment, very often in a dark environment you can find variations in some parts due to light leaks.

However, the pitfall here is that it simply means that "the screen is visible". The thing is that the viewing angle specifications are permitted to use the term "visible" until the display contrast ratio drops to an extremely low 10:1 or 5:1 when the screen is viewed from an angle (the steeper the angle from which the LCD screen is viewed, the more the contrast generally declines). In other words, they do not take into account the display uniformity of the central and peripheral areas of the screen, or the level of chromatic change, when the screen is viewed from an angle.

The ideal viewing angles is that the brightness and chromaticity is very uniform and there is not much chromatic change, even when the screen is viewed from a slight angle. The viewing angles given in the specifications are not really very helpful, but you can judge the standard of the panel type that the LCD (liquid crystal panel) adopts. IPS liquid crystal panels have the least change in brightness or chromaticity when the screen is viewed from an angle, and they are followed by VA panels. An IPS or VA liquid crystal panel can be said to indicate the superior nature of the product itself, so this is often included in the catalog or specifications. It is probably a good idea to look through the catalogs of various products.

On the other hand, monitors installed with cost-effective TN liquid crystal panels are in fact the most numerous. However, the TN type lags far behind the IPS and VA types in terms of characteristic viewing angle changes in brightness and chromaticity. Simply viewing the screen from a slightly different angle makes the coloration change dramatically, and the screen looks completely different according to whether it is viewed vertically or horizontally. If the vertical and horizontal viewing angles in the specifications are different then it is a TN type. There are quite a few products with a 20-inch wide screen or larger where colors look different in the central and peripheral areas even when the screen is viewed straight on.

When we checked the viewing angles of the FlexScan SX2462W there was absolutely nothing to criticize since, in addition to the use of an IPS panel, it is equipped with many high image quality functions, including the afore-mentioned digital uniformity correction circuit. The brightness and chromaticity throughout the whole screen is very uniform, and the coloration hardly changed at all when the viewing angle was changed.

We explained here about easy ways to check LCD monitor quality. How were the results for your current LCD? We think that many people were probably very bothered by the blocked-up shadows and blown-out highlights when the test images to check gradation were displayed, by the middle gradation banding, and by the variations in brightness and chromaticity when the monochrome images were displayed.

As we mentioned at the beginning, recently the number of LCDs with excellent display quality is on the decline. Although we would not go so far as to say that the display quality of inexpensive products is poor. Of course a high quality LCD is indispensable if you want to enjoy using your computer, properly handle the needs of applications that require color reproducibility, and to fully enjoy all the benefits of rich content.

The EIZO FlexScan LCD series has excellent display quality in those regards, and we have no qualms about recommending them to everyone. The product line-up is diverse but each model is clearly ranked according to the purpose to which it is suited and its screen size, and they all guarantee above-standard display quality. They may cost a little more than you had budgeted for but the clear value they offer exceeds their price.

If, after trying these tests, you have doubts about the display quality of the LCD that you usually use, we would certainly urge you to consider an EIZO LCD. We would also recommend that you construct a multi-display environment by making the new LCD your main monitor and the one that you have been using your sub monitor.
