Although image quality and color accuracy are probably not the most important aspects of a gaming monitor, they are still at the top of most people’s list of priorities when it comes to buying a new gaming monitor. With this in mind, it’s time to look at the image quality and color accuracy of the ASUS VG279QM.
The following results were compared with various tests and special devices.
|Standard||White dot||Black depth||Contrast ratio||Average ΔE*00||Gamma|
|Race to the modes||7083K||0,1071 cd/m²||1114.5:1||2.25||2.19|
|Cinema mode||10310K||0,1383 cd/m²||876.7:1||4.96||2.3|
For this test we have decided to use three presets for the game monitor: Race mode, Cinema mode and sRGB. As you will soon see, each has its pros and cons.
Overall, the VG279QM showed fairly accurate colors right out of the box. The official default settings were: Race Mode in Warm Mode, with brightness and contrast set to 80. Now, in racing mode, you can instantly see that the image was hot enough and too bright to be viewed daily. We recommend reducing the brightness to about 10 for a more natural and easier viewing experience throughout the day.
Before we tested the monitor’s presets, the first thing we did was adjust the brightness. In Race mode we set the brightness to 4 – or 120 cd/m². In this way we try to measure all tested monitors in a more standardized way. However, as you will soon notice, this is not always possible.
Anyway, we first tested the race mode in hot mode, and not surprisingly, the white levels were largely out of order (7083K). Yet the black levels were decent, as was the native contrast ratio, which was 1114:5:1. Our first race registered an average delta of 2.25 and a range of 2.19, which was extremely good. This is something you would expect from an IPS panel, of course.
The sRGB mode was next, and we saw a similar delta and gamma average. However, the contrast was much worse, as was the black level. This is because you cannot adjust the brightness levels when using the sRGB profile – which is annoying. The white level, on the other hand, was much closer to our ideal 6199K.
The film stand was the last and by far the worst of the party. The whites were miles from where they should have been, measured at 10310K. The black dot wasn’t the worst and neither was the contrast ratio, but that’s where the positive points stop. The average delta value of 4.96 was twice as high as the other two presets tested.
In terms of maximum brightness the ASUS VG279QM exceeds the announced 400 cd/m² and reaches 417 cd/m² – and even higher in some profiles. Unfortunately, this is probably not the best monitor for people who work a lot at night. We only succeeded with the low score of 106 cd/m².
|Standard||White dot||Black depth||Contrast ratio||Average ΔE*00||maximum ΔE*00||Gamma|
|Depth of stroke mode||6218K||0,3204 cd/m²||500.7:1||2.44||8.19||2.17|
For calibrated results, we set the RGB to 100/97/97 and reduce the brightness to 4 (120 cd/m²). We then gave DisplayCal permission to calibrate the monitor and save the profile, which can be downloaded below. After the calibration was completed, we carried out further tests to obtain a wider range of results. As you can see, the figures were much more in line with our ideal values.
The white tip was perfect and the depth of the black was also not bad with 0,1105 cd/m². The contrast ratio was quite high, with an announced ratio of 1000:1. I was very impressed with the average delta of 1.04, which means that on average this monitor displays almost perfect colors. Nevertheless, we have found some contradictions. There were large deltas between certain shades of blue – up to a maximum of 27.8 (the highest we have recorded so far). We decided to run the test several times, expecting different results, but this was not the case.
Panel homogeneity is a test we perform to see if the brightness and color on the screen are consistent. In this test a central square is used as a reference space. Then every other box is ticked to see how it differs from the reference. In an ideal world, we want every square to be green, which means it hasn’t crossed the threshold of difference – which we can set at the beginning of the test.
Pay attention: The results differ per group.
I was very pleased with the uniformity of the brightness and colour of this panel. This is by far one of the best monitors we have tested so far. It only displays results in green and yellow – squares that exceed the maximum limit turn red.
Maybe the angles were even more impressive. They had some of the best results measured on this panel, an area known for its poor performance in the unification department. Three of the four corners came back with a green score, which is generally very good.
In any case, this panel cannot be held responsible for its uniformity. It has reached an extremely high level.
The IPS panel again achieved very good results in the field of viewing angles. Even at large angles (up to 40+ degrees) there was not much difference in color or contrast. Unlike the ASUS VG278Q, viewing this screen was also no problem in the color department. I have not noticed any inversion or halo even at angles that exceed the norm for daily use.
DisplayCal measures the color space and volume after calibration.
Although the ASUS VG279QM is not the best model among IPS panels, it still scores in the color department. He proposed to increase the volume of sRGB by 116% with 97.5% coverage – in the blue zone. However, the best values for the color gamut and coverage of Adobe RGB (79.8%) and DCI P3 (82.1%) are positive.
Overall, the ASUS VG279QM color space recordings were extremely positive. Although this monitor is clearly focused on gaming, you can certainly offer an option for people who use the VG279QM for editing – especially in the sRGB color spectrum.
