30 October 2025 
I got the monitor for media and gaming. Since gaming is not just a hobby for me, but also work, I chose it carefully. I specifically wanted a Mini LED — something better than regular IPS, but without the OLED price. The 180 Hz refresh rate is more than enough since I don't play competitive shooters.

No complaints about the package, I connect via DP. The stand is okay but was a bit in the way of the keyboard, so I mounted it on a bracket — it's more convenient now, especially since I now have two monitors.

The picture is excellent: out of the box, the colors look natural, without oversaturation. Sometimes I even want to add a bit of brightness — that's a matter of taste. SDR is high quality, I just adjust the brightness according to the lighting. HDR is truly impressive — it pleases the eyes, and the black is rich in any mode. I use local dimming only in HDR — in SDR it sometimes darkens small elements, probably due to the number of zones or algorithm.

FreeSync caused micro lags in old games at low FPS — I simply turned it off, and everything became smooth. The control buttons aren't very convenient: the power button is too close to the others, but you get used to it quickly.

There's one nuance: sometimes after sleep, the monitor doesn't wake up on its own, even though the indicator changes to white. It happens rarely and only after prolonged idle, so I don't consider it critical.

Overall — an excellent monitor for the money. Even with this minor flaw, I'd give it a solid five stars. Suitable for both work and gaming, and the color coverage is truly impressive.

In the photo: on the left — AOC Q27G3, on the right — Lenovo Legion R27qe Gen 2 (IPS, without Mini LED). Its black isn't the same — but it's IPS, so that's normal.
Bright picture, deep black, realistic colors, 180 Hz, excellent HDR, great price.
Sometimes doesn't wake up after sleep, inconvenient buttons, weak local dimming in SDR
