Performance and comfort with an ultra-wide curved screen
Whether for gaming, multimedia or everyday use, the AOC CU34G4Z monitor offers you excellent comfort. With its large 21:9 format curved screen, 240 Hz display frequency and fast response time, it gives you the image quality and fluidity you need. What's more, this screen is HDR 400 certified and has a height-adjustable stand.

Excellent picture fluidity
Intense, competitive gaming demands the best technology to ensure smoother, lag-free play. This AOC monitor has a 240Hz refresh rate, making it 4 times faster than a standard screen. A lower frame rate can make enemies appear to jump from place to place on the screen, making them very difficult targets to hit. A 240Hz frame rate restores critical missing frames on the screen, revealing enemy movements in ultra-fluid motion, making it easier for you to target.
Passport to HDR!
Even the lowest level of HDR (High Dynamic Range) functionality applies a considerable upgrade to ordinary monitors. The peak luminance of 450 cd/m² allows your screen to perfect image quality with multiple chromatic spectrums and more diverse contrast. The VESA certificate ensures rich detail and realistically depicts the worlds of games and films.
