Color performance with D65 and Full Calibration
Due to the fact that ASUS ROG allows white point and brightness settings in the gamut modes – you can almost conjure up a hardware calibration here in terms of color accuracy. And, how well this works in the end, you’ll see in a moment. One more hint, I have a spectrophotometer from Calibrite (ColorChecker Studio) for quite some time.
Unfortunately, it doesn’t want to work with Calman Ultimate at the moment. Therefore I use additionally DisplayCal to validate my results. Then you can see the differences between Colorimeter vs. Spectro. But please keep in mind: Calman Ultimate vs. DisplayCal = software analysis vs. software analysis. The tests are not comparable one to one. But the delta Errors show a picture that gives us certainty.
OSD Setting D65 @ sRGB Gamut (DCI-P3 Gamut)
As you know, I always set a brightness of about 200 nits, so owners of an XG27AQMR can refer to my settings if they can also manage 200 nits. I only adjusted the brightness and the values for red, green and blue.
All other values remain unchanged in the OSD!

Basically, you only have to set the D65 correctly, then it fits for the sRGB and the DCI-P3 gamut. More than suitable for everyday use. The pros will probably still criticize it, but honestly – no gamer needs more than that. If you want even more, you have to calibrate.

For your information DCI-P3 Gamut. The D65 works also in P3 Gamut (validated: ColorChecker Studio – DisplayCal)

Not quite as nice as the sRGB gamut, but better than nothing. The gamut coverage is unfortunately a bit tight on the XG27AQMR, so it doesn’t get much better when you calibrate over it again. But the sRGB gamut I still calibrate one over.
sRGB-Gamut – Full Calibration by using Calman Ultimate
Additionally validated: ColorChecker Studio – DisplayCal
Please be careful, because Calman Ultimate and DisplayCal are not the same. (Software vs. Software – Colorimeter vs. Spectro) But you can state that my results are basically consistent. As soon as my Spectrophotometer also runs with Calman Ultimate, I can put DisplayCal to sleep again.
Uniformity
The typical IPS bleeding and glowing doesn’t leave the XG27AQMR alone. It is most pronounced in the upper left corner of my sample. I don’t mind this, but in the end it’s up to the user.
Image errors
I couldn’t find any image errors (except glowing/bleeding), dead pixels or flicker. Furthermore, I couldn’t find any problems with AMD or NVIDIA graphics cards. All my attention was on the issue of high FPS flicker and all my tests turned out in IGZO’s favor. Unfortunately, I was not able to measure the power consumption. Maybe I can make up for it, because hardware for it is ordered.
Sound reproduction
Where there are no speakers, nothing comes out. The headphone output works, but whether you use it is another story.
