Color performance after a full software calibration with Portrait Displays Calman Ultimate
Before I take a closer look at the AG276QZD2 in terms of HDR, I would like to show you that you can adjust the RGB balance with a few clicks in the OSD to achieve a very good gray scale. If you then activate the Windows sRGB profile, you get a very true-color monitor.
OSD Setting D65 @ 200 Nits
You leave the AG276QZD2 in default mode, i.e. the panel in the native gamut. Set the brightness to 80 to get the 200 nits. Apply the RGB settings as shown in the picture and you will get a very good RGB balance.
Red = 45, blue = 49 and green = 49, in case it’s hard to read. In combination with the Windows sRGB mode, this should now be really good.
Gray Scale, Saturation, ColorChecker @ OSD Default CCT Corrected – Windows sRGB Profile (10 % APL)
What did I tell you? That’s right, an almost perfect sRGB mode. You can work with it – even if I consider the AG276QZD2 to be more of a true gaming monitor. If you want it even more accurate, you have to work with ICC profiles.

With the appropriate hardware and software, you can ensure that there are no more deviations above DeltaE 3. Even the professionals should be able to get by easily.
Spectral distribution and “Eye-Safe”
As you can see the usual QD-OLED spectral image here, I have linked the image of the AG326UD here. As you know, my MK550T is currently being repaired. You can also compare all my previously tested QD-OLEDs, you won’t notice any difference in terms of spectral distribution. So please understand that I can’t show you the picture of the AG276QZD2 today.
Spectral distribution @ D65, 200 Nits (100 % White Window)
With 99.9 percent probability, the peak of the AG276QZD2 is also at 638 nm – i.e. in the red light spectrum. In terms of eye-safe, the blue light component in the peak is around 455 nm. Unfortunately, I cannot say with certainty to what extent this can already be described as eye-safe. If necessary, the blue light component can be reduced in the OSD, but be careful, this is at the expense of color accuracy.
Uniformity
In typical QD-OLED fashion, the picture uniformity is outstanding, with no dirty screen effect, bleeding or other defects.
Image errors and other issues
Apart from the weaknesses I mentioned in this article, I couldn’t find any other problems. Attention, since this is an OLED monitor, I have to point out the issue of VRR flicker. VRR flicker is most noticeable in game menus or in dark game scenes where there are extreme FPS fluctuations. Here I recommend activating a frame limiter in the game.
In my opinion, text legibility is not a problem here, but due to the unconventional subpixel layout (triangular), it can be perceived differently from person to person.
Sound reproduction
The built-in speakers of the AG276QZD2 are ok for emergencies. However, they can in no way keep up with a good headset and certainly not with a sound system. The jack connection works.
Webcam and microphone
Are not installed. This brings us to the topic of HDR.
