With FreeSync technology and only 1ms response time, you'll enjoy a perfectly smooth image to take the lead in games and maximise your chances of victory!
AOC takes you on a journey through your favourite games with this large gaming monitor. Enjoy the pleasure of the 34" curved panel (Ultra Wide QHD resolution of 3440 x 1440) to fully immerse yourself in the action and experience unique moments of relaxation. The VA display technology features true-to-life colours and an excellent static contrast of 3000:1, making it ideal for enjoying the graphics of your favourite games.
In competitive games that demand responsiveness, it's very important to have the right hardware to aim for victory. AOC has equipped this monitor with a 144Hz refresh rate to ensure that you can drive, aim and react more efficiently.
But that's not all: using AMD's FreeSync technology, the CU34G2X/BK is able to synchronise its display frequency with that of your compatible graphics card to significantly reduce screen tearing and other visual disturbances such as jerkiness. Moreover, the response time of only 1ms is another welcome addition as it allows the display to better handle scene transitions in fast phases to keep input lag and ghosting effects to a minimum.

The screen is pretty good for the price, good quality ratio. However, there is a big problem with the colour settings (which are horrible by default). The presets are completely random and the screen only retains part of the colour settings systematically, so you have to redo the setting every day when you switch on (if you use several input sources it's even worse).
Without this problem it would be great!
I have had this monitor installed for 6 months now.
It suits me perfectly.
It meets my expectations.
However, I have kept my SAMSUNG SyncMaster 2333 as a second monitor. I can open many windows without getting lost.
As for the stability, I was a bit worried before buying this screen, because of the shape of its stand: finally it is excellent!
I recommend this product and give it the highest rating.
The screen is very good and the stand is very good. The screen doesn't shake when you put it on your desk and the quality is very good for the price.
I have owned this screen for a year now...
The advantages:
-No light leakage or dead pixels on reception,
-Good contrast ratio,
-Colour consistency,
-144hz Va panel,
-10bit and g-sync compatibility can be enabled in the nvidia menu.
The minuses:
-Low brightness if the screen is used in a bright room.
-The whites have a tendency to turn yellow.
(After rebalancing the colours this improves but at the expense of brightness)
-No sharpness adjustment.
-OSD button not easy to use, better to use the AOC g-menu software.
-HDR mode is anecdotal or useless.
-The price is still a bit high today, a Gigabyte G34WQC, Xiaomi 34 or a Huawei mateview GT do the same job for less than 500 euros.
(With Windows colour calibration reset)
Screen setting :
-Contrast 70
-Brightness 100
-Gamma 3
(The factory screen brightness is rather low to cheat on this setting, use contrast at 70 max and use the following colour balancing to prevent white from tending to yellow).

Very good screen colour and game comfort, but far from the 1 ms in games plus top 10 :D
After 6 months, the screen stopped displaying (OSD menu, DP and HDMI sources). Strangely it is still detected, I see it as a second screen when I connect another screen.
The screen is under warranty, but I have to pay for shipping, and it's expensive...
I'm in contact with AOC for the support, to follow.
My only regret is that I didn't change my screen before....
I can work on several files at the same time (opening several windows) excellent!!!
Excellent proposal on the material
Reactivity and speed
More than reasonable quality/price ratio
I recommend :)
In the same universe: cu34g3s
