HDR performance
The AG326UD works almost equally well with both NVIDIA and AMD graphics cards in terms of HDR. I have three different OSD HDR settings for you here with the RTX 4090, which you should take a look at first. This is basically the “worst case”. Although that’s putting it very harshly, because the AG326UD isn’t that bad in the end.
HDR True Black 400
HDR Peak 1000
HDR Game
Interim conclusion HDR
The True Black 400 mode has two weaknesses, firstly the RGB balance and secondly the EOTF tracking is below the required line. This affects the brightness, in other words, the AG326UD is slightly too dark in True Black 400 mode. This ultimately affects the color accuracy – see ColorMatch HDR.
The Peak 1000 mode is also a little too dark for smaller APLs. With large APLs, from 10 percent, the well-known panel dimming also occurs. All QD OLED monitors are generally affected by this. At least AOC offers an option to counteract panel dimming with the HDR Game mode. But this also has its disadvantages. Here, the image becomes significantly too bright – especially with smaller APLs. This can or will lead to the so-called “crashed shadow detail” effect. Color accuracy also suffers the most here.
Nevertheless, it must always be noted that you get real HDR with an OLED because the contrast is so high. The brightness of OLED monitors is not quite at the level of comparable OLED TVs, but it is still impressively good. AOC should take another look at EOTF tracking, especially in relation to NVIDIA GPUs. It looks slightly better with an AMD graphics card, but not quite perfect either.
