The AOC CU34G2X is an extraordinary ultrawide gaming monitor. It’s anything but a 144Hz board with Adaptive Sync support, so despite the fact that it’s anything but formally guaranteed by AMD nor NVIDIA for variable refresh rate (VRR) backing, FreeSync and G-SYNC still both work on it.

It has low info slack, and despite the fact that it’s anything but a fast generally speaking reaction time, there’s apparent black smearing, which is normal of VA boards. Talking about which, it’s anything but a high local contrast ratio, yet that implies it has tight viewing points, so it’s anything but ideal for center gaming.

The 34-inch screen and 3440×1440 resolution assist with conveying a vivid gaming experience, and it’s anything but a genuinely forceful 1500R curve to bring the edges of the screen inside your point of view.

The AOC CU34G2X has a gamer-arranged structure with dark plastic and red accents all through. It’s anything but a genuinely forceful curve to assist with bringing the edges inside your field of vision. The stand and the actual screen have huge impressions, so you’ll require a major desktop to put the screen on.

The stand has a huge impression, and there’s a decent measure of wobble from the screen. It’s anything but the amount remains from the front, yet there are two feet toward the back.

Build Quality

The form quality is nice. It’s made altogether out of strong plastic, and the stand feels stable when making ergonomic changes. Nonetheless, the screen wobbles decently effectively on the stand, and the base bezel isn’t as expected connected to the screen all through.

The controls are truly difficult to press and even reason the screen to shift a piece. Likewise, there are elastic holds at the lower part of the feet that fall off without any problem.

There are five buttons underneath the right half of the screen to control the on-screen display. Notwithstanding, they’re difficult to press.

Setup and Calibration

The CU34G2X’s Standard picture mode with Warm shading temp and Gamma 1 is the default and best setting. Our tests demonstrated it to be extremely precise, and we couldn’t develop the underlying numbers in the User color temp mode. On the off chance that you need a more obscure gamma, Gamma 3 looked great as well, on account of the VA board’s high contrast.

The backdrop illumination doesn’t top at a significant level and will go down to a faint 38 nits on the off chance that you zero the splendor slider.  For HDR content, we propose the DisplayHDR mode for the best difference and color constancy.

Here are the brilliance settings for usually utilized output levels in SDR mode. At the point when an HDR signal is recognized, the backdrop illumination is bolted to its greatest setting.

Pros Cons

Blur-reduction up to 144 Hz HDR doesn’t look much better than SDR
Extended color
Accurate out of the box


Of course, you can get the ultrawide experience with any 21:9 screen, however, the AOC CU34G2X is by a wide margin the best ultrawide decision for quick and jittery games; those that require fast reflexes and advantage from the more extensive FOV, similar to shooters or dashing titles. I say it in each screen review I for one do: 144Hz+ refresh rate and 1ms reaction time will best any screen with more terrible specs and indeed, that is the situation.

The special reward here is that you can get it’s anything but a truly reasonable cost without a doubt. Other than the marginally dreary color and HDR execution – which don’t matter quite as much when you’ll principally be gaming on it with one of the best gaming laptops or best gaming PCs.
