Connectivity and Ergonomic Stand

The monitor provides HDMI and DisplayPort inputs alongside a built-in USB hub for peripheral connectivity. Its stand offers height adjustment, pivot, swivel and tilt so the screen can be positioned for any desk layout. ASUS DisplayWidget Center software lets users change settings and access OLED Care functions with a mouse.

Thermal Design and Power Efficiency

A custom heatsink and advanced airflow design dissipate heat without active cooling, keeping the panel stable during long sessions. OLED Care features such as pixel cleaning, screen saver and an optional uniform brightness setting reduce the risk of burn-in. Typical full-screen brightness is 275 cd/m², while HDR peaks reach 1,300 cd/m².
