AOC CU34G3S-B 34" Curved UltraWide Monitor

TLDR: SDR is great. HDR color is clamped down and makes red colors look orange with no way to fix the issue. Otherwise a typical QD OLED with all the positives and negatives, but 100-200 dollars less than the competition. Full Review: SDR mode is great. 250 nits is not as bright as most lcd monitors, but with the best color contrast and motion clarity. You NEED to use it in a dark room. It doesn't take much ambient or direct light make a QDOLED appear purple grey and ruin the black level. The usual caveats apply like all QD OLEDS, these are dim displays, If you are used to using an LED HDR 1000 monitor or TV, then OLED HDR 400 can look really underwhelming. Don't expect brightness like your OLED phone that can hit 1000nits white across the whole display. They use a different technology for larger oled displays. True black HDR 400 is a bit misleading, the display has a hard cap of 250 nits for full white screen brightness, with 400 nits for 10 percent, and 1000 for 2 percent. The ABL (auto brightness limiter), can be really distracting. Daylight desert and ocean scenes in MH wilds, Outdoor daytime in Cyberpunk, and the bright snowy daytime scenes in Metro are some of the worst case scenarios. With HDR 1000 if you look at the sun or sky you get that shock of brightness that makes it feel like you just stepped outside, HDR 400 is simply too dark to achieve this effect. A typical mini led HDR monitor can sustain 1000 across the whole screen, but has to dim small highlights like headlights, streetlights, fireworks, stars to avoid excessive backlight haloing. OLED monitors due to power heat and burn in issues have the opposite problem, they have pin point super bright highlights and dark scenes have unmatched quality on an inky black background. But the brighter the scene gets, all those 400 and 1000nit highlights flatten out into a 250 nit image. It cannot display 250 and the 400 and 1000 highlights at the same time. THE PROBLEM: The only reason this is a 3 star review is that this monitor clamps the colors down in HDR mode and there are no settings to fix it. Red especially is under saturated. Red looks closer to orange when HDR is activated. Some recommend using Nvidia vibrance at 65 percent to help compensate. The issue is that red is clamped down more than green and blue, so boosting the vibrance even 5 percent will make skin tones look yellow. In SDR mode, you have native color, srgb, and p3 to choose from. Color, contrast, brightness. There are no options to adjust anything in HDR, everything is locked down. This defeats the whole point of getting a QD-OLED which is not as bright as a W-OLED. QD OLEDS have better colors and color saturation which this monitor does not use. If I could get some kind of confirmation that a fix or update is in the works to fix the HDR color then I would love to keep it. If not, I am probably returning this one. This monitor has been out for roughly six months now, If they are planning to release a fix I haven't seen any evidence of it online so far. I don't really want to spend an extra 150 for features I don't need, but the OLEDs from MSI and Asus don't seem to have these color issues. Everything aside from the HDR color is great and in line with what you get with other QD OLEDS from Asus or MSI, minus some features and customizations. If you can tolerate the bad HDR color or don't plan on using HDR then maybe it will be worth the 100-200 dollar savings.
