Information about the number of pixels on the horizontal and vertical side of the screen. A higher resolution allows the display of a more detailed and of higher quality image. The pixel pitch shows the distance from the centers of two neighboring pixels. In displays, which have a native resolution (the TFT ones, for example), the pixel pitch depends on the resolution and the size of the screen. 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. Dimensions, weight and color Information about the dimensions and the weight of the specific model with and without stand as well as the colors, in which it is offered to the market. Width
We retested the input lag after updating the Hardware Abstraction Layer through the ASUS Armoury Crate software. The input lag at the max refresh rate hasn't changed, but the 60Hz input lag is significantly lower and similar to most other high-end gaming monitors. Often even a higher peak luminance can be achieved under certain conditions. For example, when a smaller area/APL of the display is used for showing a bright object, when a bright object is displayed for a short time, etc. Of course the main thing we want to test is what improvements the Blur Reduction mode offers when it comes to motion clarity and gaming. The following pursuit camera photos give you an indication of observed motion clarity as the human eye would see it at the top, middle and bottom areas of the screen. HDR signals cannot be calibrated, but you can choose from two HDR modes, Gaming and Cinema, that look and measure similarly. Gaming and Hands-onGraphics card settings were left at default with no ICC profile or calibration active. Tests were made using an X-rite i1 Display Pro Plus colorimeter. It should be noted that we used the BasICColor calibration software here to record these measurements, and so luminance at default settings may vary a little from the LaCie Blue Eye Pro report you will see in other sections of the review. The materials were of a decent standard and the build quality felt good. There was no audible noise from the screen, even when conducting specific tests which can often identify buzzing issues. The whole screen remained cool even during prolonged use. Keep in mind that not all Operating Systems and applications handle scaling the same. More recent versions of Windows (8.1 and 10) tend to handle it all better, and recent versions of Mac OS are pretty solid as well. Some applications and games don’t handle scaling correctly and so you can end up with some things with very minute text and fonts and some things which don’t scale completely in every place. Keep this in mind if you’re selecting any super high resolution display as it could be an important factor. You need to ensure you have the necessary operating system and applications to handle scaling effectively for your needs. It does make life a bit more complicated than if you just ran at a native resolution, which is where the more common 2560 x 1440 res fits in to the 27″ display space. The XG27UQ provides another answer to the problem in the form of DSC (Display Stream Compression). This is a VESA standard that allows compression of the image in a reported “visually lossless” way. This negates the need for colour compression from reduced chroma or any other means, and has been added to the display’s DisplayPort 1.4 connection. VESA have a whitepaper on DSC if you want to know a bit more about it.
Luminance uniformity of the screen was only moderate on our sample, with 57% of the screen within a 10% deviance of the centrally calibrated area. The sides were a bit darker with the left hand edge showing the most significant variation, dropping down by 24% in the most extreme example. Information about the brightness of the screen. It is measured in candela per square metre (cd/m²). dE average / maximum– we aim for as low as possible. If DeltaE >3, the color displayed is significantly different from the theoretical one, meaning that the difference will be perceptible to the viewer. If DeltaE <2, LaCie considers the calibration a success; there remains a slight difference, but it is barely undetectable. If DeltaE < 1, the color fidelity is excellent.Radiance is a critical feature on the subject of functionality considering it alters eligibility. Extra radiance is consistently finer, however not unquestionably vital in a number of instances. Asus's ROG Strix XG27AQ facilitates a radiance of 400 cd/m2.. This measure of vividness perhaps be looked upon as more than ordinary particularly with the condition the monitor is Standard Dynamic Range on the grounds that they don't feel the necessity of so much luminance as Standard Dynamic Range ones. Displays with and around this luminance extent would offer an enjoyable productivity, light video game sessions and a mixed media viewership experience. With the response speed being 1 ms, the ROG Strix XG27AQ switches colours super fast and retains the image blur-free in motion. Asus ROG Strix XG27AQ: Price UK The total lag measured was a very impressive 3.70 ms total. The pixel response times should account for pretty much all of that display lag at around 3.40ms, and so we can say that there appears to be almost no added signal processing lag on this screen at around 0.30ms. An impressive result from this display and making it suitable for fast and competitive gaming.
Styling is distinctly Asus ROG with nothing to distract in the front. A small ROG logo adorns the 21mm wide trim strip across the bottom while the remaining bezel is flush, just 7mm wide when the image is present. The Asus ROG Strix XG27AQ makes a good candidate for multi-screen setups where a thin dividing line is desired. Alignment marks in the GamePlus menu aid in marrying the images together. This can be useful for highly detailed design, photo and CAD/CAM work to some people. For gaming and multimedia you do get an improvement in the image sharpness and clarity thanks to the smaller pixel pitch and higher PPI. Depending on your viewing distance, eye sight and game settings you may or may not notice the difference in running at 4K resolution on a 27″ screen compared with a more common 1440p native display. However, there are plenty of people out there who do notice the difference and have invested in 4K resolution screens of various sizes, many in this kind of range, and love that extra level of detail and clarity they get. Keep in mind that a 4K screen has 225% the pixels that a 2560 x 1440 display has, so that is a massive extra drain on your graphics card and system resources. You might want to consider whether you would be better off with a lower 1440p and instead pushing your frame rate and game settings up higher. Display Stream Compression The ratio between the horizontal and the vertical side of the display. Some of the standard and widely used aspect ratios are 4:3, 5:4, 16:9 and 16:10. We carried out some further response time measurements at 144Hz which is the maximum refresh rate of the screen. We measured an average 6.8ms G2G response time in this mode which was good although not as fast as we might have expected from a modern IPS gaming panel to be honest. We had seen the PG27UQ reach down to 5.3ms G2G at 144Hz with more consistent performance, although that screen does feature a Native hardware G-sync module as we’ve discussed earlier. Some transitions reached down as low as 3.4ms which was great, but the problem was that some other transitions were much slower up to 11.1ms in the worst case. At this max refresh rate the overshoot is at a low level and doesn’t cause any issues in practice which was great news. Refresh Rate ComplianceThe dynamic contrast shows the ratio between the brightest and the darkest color, which the display can reproduce over time, for example, in the course of playing a video. The screen uses overdrive technology to boost pixel transitions across grey to grey changes as with nearly all modern displays. The part being used is an AU Optronics M270QAN02.3 AHVA (IPS-type) technology panel.Have a read about response time in our specs section if you need additional information about this measurement. Moving on to the screen itself, the XG27UQ uses an IPS panel. This display type is coveted by content creators due to its accurate colors, and that’s definitely the case here. Using my Datacolor SpyderX Elite, I was able to verify that the display covers 100%+ of the sRGB color space and 91% of DCI-P3, and also offered decent out-of-the-box calibration. If you’re a hobbyist creator, you can use it confidently without any adjustments, but following SpyderX’s calibration process, I was able to refine it to where color inaccuracies were imperceptible, even outperforming the Acer Predator X35 gaming monitor, which is triple the price. If you don’t have a calibration tool, the sRGB mode also does a good job of closing this gap, at the expense of color range.
