There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.AHVA IPS

The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.8 bits

Frame Rate Control (FRC) is a method, which allows the pixels to show more color tones. With quick cyclic switching between different color tones, an illusion for a new intermediate color tone is created. For example, by using FRC, a 6-bit display panel is able to show 16.7 millioin colors, which are typical for 8-bit display panels, and not the standard 262200 colors, instead. There are different FRC algorithms.No

The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC.16777216 colors

The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.W-LED

Both are very different monitors and it depends on the content and other factors like your environment (pitch black room or a brighter environment etc). The Acer has a better color stability and no color shift issues while the Samsung has. In dark image content (Sci-Fi or Horror titles or even darker areas in games like Witcher 3 in a cave for example) the Samsung usually wins because of the contrast ratio. The farther away you sit from the CHG70 away, the better the overall image quality and less VA glow. Same applies to the Acer (fewer IPS glow when increasing the distance to the panel). Personally, I still would prefer IPS simply because of the color stability and combined with it the viewing angles, which are usually much harsher than on a TV for example, where a VA panel mostly wins on a TV (also because good TVs have a stronger contrast ratio than current VA monitors).

Right now, there’s one choice for gamers with high-end PCs to make: do you want a 4K monitor at 60Hz or a 1440p monitor at 144Hz? If it’s the latter, then you should take a look at the XF270HU. As well as hitting that desirable 1440p and 144Hz spec, the XF also comes with an IPS display for better viewing angles and colour accuracy over the usual TN panels. Best of all, it’s available for around £470. Let’s put it to the test.

The XF270HU is a variant of the popular XB270HUbprz, offering the same 1440p IPS display at a rapid 144Hz refresh rate. The difference denoted by the first two characters is the choice of anti-screen-tearing technology; the XF comes with Freesync (for AMD cards) and the XB has G-Sync (for Nvidia cards).

The XF270HU has a simple but not unattractive design, with a thin matte black plastic bezel on each side of the display and the Acer wordmark at the bottom centre. There are buttons along the bottom right of the screen for controlling the on-screen display, and these work well for making adjustments.

Overall, the XF270HU’s design is sensible if not inspired. There’s a good selection of ports, a capable and stable stand and a professional design. This monitor doesn’t have the gamer cachet of the more expensive XB271HU, but that’s OK — you should be able to count on the expansive 27-inch IPS panel to draw the eye.

Moving onto colour accuracy, we see extremely good results across the board, with most results having a Delta-E value of below 1.00. That’s brilliant, and the average of 1.42 is the result of only two shades being out of whack. Overall, a strong result that’s consistent with the IPS-style panel used here.

Here we see the Spyder’s rating of the monitor, which includes praise for pretty much everything except the luminance uniformity. I’d agree with that assessment; the benchmark identifies few other weaknesses for this XF270HU unit.

High refresh rates are awesome enough, but the XF270HU offers other advantages too. For example, compard to the 144Hz Viewsonic XG2401, it offers a higher resolution (2560 x 1440 versus 1920 x 1080) and it uses an IPS panel for better colours and a overall better-looking image. The new resolution is more demanding than 1080p, but not quite so ridiculous as 4K. You can put together a PC with the GTX 1070 or 1080 and a middling processor, and you should be capable of pretty solid performance at 1440p without spending a great deal.

While games look better on an IPS screen than a TN one, moving to the more expensive screen technology also makes a monitor better suited for professional use. I spend a lot of time editing photos and watching videos, and these tasks are certainly improved by an IPS display like the XF270HU.

One side effect of this switch is that viewing angles become much more generous, making looking at a monitor dead-on less important — handy for showing off a new photo or web design to people standing behind you. Colour accuracy is also vastly improved compared to the average TN panel monitor, which is essential when you’re colour-grading video or editing photos. Just consuming content is also easier with a good IPS monitor, whether you’re watching YouTube clips or a feature film. The 27-inch diagonal isn’t quite as immersive as a 32-inch 16:9 monitor or a 35-inch 21:9 titan, but it’s still perfectly adequate for one or two people watching a video.

The XB270HU is an outstanding monitor for getting work done and watching videos, something that the TN panels of the BenQ XL2730Z, Asus PG278Q and Acer XG270HU can’t match (despite their best efforts).

The Acer XF270HU is a brilliant choice for anyone that wants a good-looking gaming monitor, and doesn’t care to spend extra for 4K or G-Sync. Whether you have an AMD graphics card or your computer is strong enough to not need G-Sync, saving a few hundred bucks by going with this Freesync equivalent is definitely worth considering.

The chief alternative to the XF270HU is the Asus MG279Q, the Freesync equivalent of the Asus ROG Swift PG279Q. It boasts a similar IPS panel, 1440p resolution and 144Hz refresh rate, and costs a similar amount. The chief difference is in styling and in cost; it’s best to check the latest prices if you don’t mind coming down on either side of the Asus / Acer war.

The past year or so has seen the arrival of some truly exciting gaming monitors. This is a result of the combination of new, high-refresh-rate IPS LCD panels with either AMD FreeSync and Nvidia G-Sync adaptive sync technologies.

The headline-grabbers have been the top-end G-Sync models, such as the Acer Predator XB271HU and X34A, and the Asus ROG Swift PG279Q and PG348Q. However, also available are slightly less flashy but equally capable AMD FreeSync models, such as the Acer XF270HU.

It boasts a 27in IPS panel with a 2,560 x 1,440 resolution, a 144Hz refresh rate and a fully adjustable stand, and it’s at least £150 cheaper than its G-Sync-equipped sibling.  Does that make it the gaming monitor bargain of the year?

One thing you may have noticed if you follow Acer’s product announcements is that the XF270HU’s name doesn’t include the Predator brand. This seems to have become a bit of a trend among monitor manufacturers at the moment, with G-Sync models being given top billing and the FreeSync alternatives being treated as lesser beings.

However, from a practical perspective, there’s very little “lesser” about the XF270HU. But the same can’t be said when it comes to the design; it’s pretty obvious that not all of the £150 price difference between the XF270HU and the XB271HU is down to the cost of a G-Sync chip.

The XF270HU is pretty plain-looking, with a simple design that’s finished in a dull matte plastic. Overall, its build quality also appears a little less refined.

Moreover, the Acer XF270HU uses an IPS LCD panel, so viewing angles should be fantastic. In addition, Acer claims 100% coverage of the sRGB colour space, so overall colour accuracy should be pretty decent too.

Then there are the gaming features. AMD FreeSync should take care of screen tearing and stutter, while a maximum 144Hz refresh rate matches the majority of existing TN panel-based gaming monitors.

Some rivals can refresh a little faster, but the difference between 144Hz and anything higher is almost imperceptible. Like other fast-refresh IPS panels, the XF270HU has a response time of only 4ms, compared to 1ms for some gaming TN panels – but again, for most users this difference will be barely noticeable.

The XF270HU requires a bit of assembly before you can fire it up, with the base screwing onto the stand and the monitor clipping on top. Attaching the base is a bit fiddly, but it’s a fairly painless process: at 69 x 6 x 38cm and 7kg, the monitor isn’t too big and unwieldy – unlike 30in+ alternatives.

Next, check the onscreen display (OSD) to see if there’s a FreeSync option hidden within the menus; if there is one, turn it on. However, if you don’t find this setting, that doesn’t necessarily mean your monitor doesn’t support FreeSync – some, such as my own Acer XF270HU, don’t display the option in the OSD.

Open the Nvidia Control Panel (you can find it by right-clicking on your desktop, or on the GeForce icon in the taskbar). You’ll see a big list of options listed on the left, divided into four groups: 3D Settings, Display, Stereoscopic 3D and Video.

Nvidia makes it very easy to confirm that G-Sync is working. In the Display settings of the Nvidia Control Panel you’ll find a tickbox labelled “G-Sync Compatible Indicator”; when this is ticked, a box saying “G-Sync On” appears at the side of any full-screen (or windowed) apps that are using G-Sync.

First, in the Nvidia Control Panel, click on “‘Manage 3D settings” (near the top of the list), then, in the Global pane, scroll down to find “Monitor technology” and click to set this to “G-Sync Compatible”. Hit Apply and check to see if the problems have been rectified.

This test ended in 2019, as we feel that we now have a good understanding of what types of content are likely to cause burn-in. However, we still haven"t addressed the issue of longevity in general, and we don"t know if newer OLED panels are still as likely to experience burn-in. To that end, we"ve decided to start a new accelerated longevity test to better understand how long new TVs should last and what are the most common points of failure. Although burn-in isn"t the main goal of this test, we"re hoping to better understand how newer OLED panels compare to the older generation of OLEDs. It"s generally accepted that burn-in isn"t as much of an issue as it used to be, but it"s unclear just how much better the newer OLED TVs are. With new panels, new heatsinks, and even brand-new panel types like QD-OLED, there are a lot of unknowns.

The 20/7 burn-in test ran for about two years, from August 31, 2017, until November 15, 2019. The goal of this test was to see whether burn-in could happen for the three most popular TV types (VA LCD, IPS LCD, and OLED). These are the results of our experiment:
