You have to change some settings

Pros: Stunning colors and contrast, buttery-smooth 240Hz, low latency, excellent value for QD OLED.

Cons: Mediocre text clarity, aggressive pixel protection (blackouts), HDR sometimes inconsistent with black and saturation.

If you're just gaming in a dark environment and text isn't crucial, this is highly recommended – you get a premium OLED image for a budget. But for heavy productivity, text work, or if you don't like unexpected screen interruptions, you're better off looking at more expensive alternatives with better firmware or less aggressive protection (or even a high-end IPS). I give it a 7.5/10: beautiful picture, but with typical OLED annoyances that can break the experience.

A very nice monitor

Easy to set up
Vibrant color
Can't adjust height of monitor (but that's okay because it wasn't advertised as adjustable. Just something to keep in mind)

Very nice monitor! Vibrant colors. Super easy to set up.

Nice gaming screen for 1440 gaming

Beautiful colors
Design of the screen
Fast response time

I previously owned the AOC 24G2SAE/BK and wanted to upgrade to a higher-resolution monitor. That's why I chose the AOC Q27G4ZR, primarily because of its 1440p support. The difference is immediately noticeable while gaming: sharper textures and more detail, without sacrificing performance. The screen responds quickly, which is beneficial for competitive shooters. The colors are well-tuned and provide a balanced image. The design is also a step forward, with a thin bezel and a sturdy stand. The settings menu is logically structured and offers plenty of options to customize everything to your liking. I rarely use the extra gaming options, but it's handy that they're there. For this price range, the monitor offers a lot of quality.
