Switchable Refresh Rate 160/320 Hz
The monitor supports dynamic switching not only of resolution but also refresh rate: at a resolution of 3840×2160 pixels, it reaches 160 Hz, while in 1920×1080 pixel mode, it increases to 320 Hz—an optimal choice for competitive gaming. In both cases, the Fast IPS panel response time starts from 1 ms (or from 0.5 ms with MPRT technology activation). Additionally, the screen is certified with the VESA DisplayHDR 400 standard.
Extended Color Gamut
The model provides an extended color space coverage at about 124.7% of the sRGB palette. For better visibility in dark scenes, there is a Shadow Control function, and for fine-tuning the image, there are Game Colour tools that allow you to adjust color saturation, and Dial Point—a digital crosshair in the center of the screen.
Convenient Ergonomics
The position of the AOC U27G4R display can be adjusted for height, tilt, and swivel. The interface arsenal includes two HDMI v2.1 ports, one DisplayPort v1.4, and a four-port USB hub type A version 3.2 Gen1 (5 Gbps). The model does not have built-in speakers, but it does have a 3.5-mm audio output for connecting headphones or external audio systems.
