Technical benefits: what it actually gives you

QD-OLED: colour from quantum dots, not filters

A WOLED uses a white subpixel with colour filters; a QD-OLED emits blue and converts it with quantum dots, with no filter eating energy. In practice that means more saturation at high brightness and 110% DCI-P3 coverage. In game it means the colours that carry information — enemy outlines, ability markers — stand out more against the background.

HDR400 True Black: real black, not dimmed black

True Black certification requires a black level below 0.0005 nits. Against an LCD with local dimming, here each pixel switches off completely, so on a night map in Valorant there's no grey veil hiding an enemy crouched in a corner.

240 Hz at 0.03 ms for the price of a fast LCD

That's this monitor's decisive argument: it delivers the same 240 Hz / 0.03 ms pairing as a premium OLED for considerably less money. What's been trimmed is the chassis and the stand's ergonomics, not the panel.

How it performs by game type

Tactical shooters

Valorant · CS2
9/10

240 Hz, instant response and the best contrast of the three for picking silhouettes out of dark areas. Against the BenQ you lose 40 Hz and the DyAc strobing; against the ASUS you lose very little and gain on price. For a competitive player on a budget, it's the best ratio in this category.

Mechanical speed and precision

Rocket League
9/10

Almost as good as the ASUS: the same panel speed and even more colour saturation, which helps track the ball. It falls behind on stand adjustment, which matters if you need a very specific height to play comfortably.

High click-rate PvP

Minecraft
8/10

The same warnings as any OLED with a fixed HUD, offset by colours that make a shader world look far better than on an LCD. The 147.6% sRGB coverage is more than the game needs, so it's worth using a clamped colour mode so it doesn't look oversaturated.

Mixed competitive play

Roblox
9/10

A very good all-rounder: the same 240 Hz as the ASUS, an excellent panel and a friendlier price. If the machine is shared at home between gaming, homework and video, this is the one that gives the most performance per euro.

Pros, cons and who it's for

Strengths

  • QD-OLED panel at 240 Hz and 0.03 ms for the price of a fast LCD
  • 1,500,000:1 contrast and HDR400 True Black
  • 110.2% DCI-P3: colour far beyond any TN
  • G-SYNC Compatible
  • Three-year warranty

Weaknesses

  • The stand is basic next to the BenQ's or the ASUS's
  • AOC doesn't publish SDR brightness in nits on this listing
  • Burn-in risk inherent to any OLED
  • The four-button menu system is awkward

Ideal for: Someone who wants to get into 240 Hz OLED for as little as possible and can live with a simple stand.

Review summary

4.5 (218)

The consensus in the reviews is 'best OLED for the money': buyers arriving from 100-144 Hz IPS panels describing the jump as enormous, with praise for the glossy finish and the HDR. Criticism concentrates on the basic stand and the four-button menu navigation.

Best in this price, Slight adjustment, Amazing quality.

It’s an OLED so its gonna be good. I didn’t have any text fringing or eye strain even after 4 hours straight use. Picture quality is great. Brightness is good enough for me.Im impressed by the colors on it. It doesn’t get any better in this price. Now the cons are that the upper side of the panel is very thin so if I want to tilt it up or down with my monitor arm I’d feel more confident doing it holding the bottom part. The HDMI doesn’t support more than 165hz on this monitor so I had to use display port for that sweet 240hz refresh rate. You could use an HDMI to DP cable if you don’t have any display port option in your pc or laptop. The bezels are a bit thicker than I expected, You’ll noti

Great entry OLED monitor

Beautiful display and i really like the glossy finish. Great HDR and peak brightness. Very happy. Stand is pretty basic and 4 button control is kinda whatever. Overall great entry into the OLED world

in love with this monitor

this was a MASSIVE upgrade from my last monitor in EVERY department (onn 24 inch IPS 100hz). this is also my first OLED. i'm blown away. amazing picture quality, great colors. i was really worried about HDR after all of the reviews saying it's really bad on this monitor. i calibrated it, changed the setting in the AOC g-menu software to "displayHDR" and tweaked the colors slightly in the AMD software and i think it looks fantastic in my games. this is also my first HDR monitor though, so i have no real reference point lol... i will say if you turn HDR off though this monitor is not very bright at all. as others have said, brightness is linked to contrast on this monitor, so if you need to in
