A great opportunity to experience true HDR at a reasonable price.

3 September

I wanted to get acquainted with HDR and was looking for a monitor that would really showcase it (because HDR10 isn’t the real thing), but at a low price. This monitor was always ranked first in every rating.
I saw HDR, and now I turn it on everywhere whenever possible (+ I often add the RenoDX mod in games). It’s a great feature, and it was worth it.
27 inches is also a great size for a desk. It’s hard to imagine a larger monitor on a desk. But 24-inch monitors now look pathetic.
At 1440p, games run very easily even on mid-range graphics cards with the help of DLSS. So if you’re afraid to switch from 1080p because of FPS loss—you’re worrying for nothing.
The bad thing is that HDMI 2.0 outputs a maximum of 144 Hz (which isn’t critical), and the maximum color depth is only 8-bit. Keep this in mind, because it would be stupid not to use all the monitor’s capabilities.
1100 nits is a looooooot, especially at night. So a program for quickly reducing the brightness has become essential for me.
If you use the strong local-dimming mode, some small light sources (such as stars) look really bad. After all, 330 zones are not enough, but the problem is that even if you increased their number tenfold, you still would NOT get OLED quality. The technology itself is problematic.
After being turned off, the monitor will crackle a little as it cools down after heating up significantly to 1100 nits. It’s a bit annoying when you’re going to bed.

HDR, 10-bit, price, 90-degree rotation.

HDMI doesn't unlock the full potential, there are too few dimming zones, and 1100 nits is too much.

Definitely vartiy respect

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
