Up-scaling resolution from UHD, WQHD to Full HD

NVIDIA G-Sync technology which synchronizes the monitor’s refresh rate to the GPU’s render rate, so images were displayed when they’re rendered.

144Hz rapid refresh rate and 1ms (GTG) fast response time

Multiple connectivity including VGA, HDMI(MHL), DVI, Displayport and USB 3.0

Multi-function ErgoStand with tilt, swivel and height adjustment High Resolution

Acer XB0 series featured with UHD (4K2K) and WQHD resolution, presenting more stunning, high quality image ever. High resolution not only enhanced users’ working efficiency, but created an outstanding visual enjoyment to every user.


NVIDIA G-SYNC(tm) ensures that every frame rendered by the GPU is well displayed. Its revolutionary performance is achieved by synchronizing monitor’s refresh rates to the GPU in GeForce GTX-powered PC. G-SYNC even eliminates screen tearing and minimizes display stutter and input lag when users start playing games.

GPU seeks to synchronize with monitors, but when GPU runs inconsistent with monitors, persistent tearing occurs. G-SYNC can match every render frames at varying rates, and solve the tearing image of PC games successfully.

In order to eliminate screen tearing, users can turn on V-SYNC, but it does cause stutter and game lag on display at the same time. Nowadays, G-SYNC can fix above issues since the display accepts frames as soon as the GPU has rendered them which accelerates every gaming experience, and perfectly maximizes input response.

Immersive 3D imagery

NVIDIA(r) 3D Vision(tm) 2 Wireless Glasses Kit and NVIDIA(r) 3D LIGHTBOOST(tm) technology provide immersive 3D imagery so that users can experience gaming and enjoy home entertainment like never before!
