Built around your game
240Hz gaming
The high refresh ceiling and 0.03ms GTG response suit quick camera movement and fast action. Balance graphics settings with your system's capabilities to make practical use of the panel's speed.
Tandem QD-OLED colour
Self-emissive pixels deliver dark blacks, while 99% DCI-P3 coverage and 10-bit colour support nuanced images. Delta E below 2 adds a controlled colour foundation for supported content and appropriately configured applications.
OLED Care Pro
The Neo Proximity Sensor can switch the picture to black when you leave the desk. Panel-care settings, a custom heatsink and maintenance routines support daily use without removing the need for sensible OLED habits.
HDR and adaptive refresh
HDR10 input and DisplayHDR 400 True Black certification support high-contrast HDR content. G-SYNC Compatible and FreeSync Premium Pro help the monitor track a supported GPU's changing frame output.
Flexible desk position
Height, tilt, swivel and pivot adjustment make the panel easy to align with your seating position. DisplayPort 1.4 DSC, dual HDMI 2.1 FRL and the USB Type-A hub support multiple sources and peripherals.
Designed for your gaming desk
The display is one part of a complete gaming setup. Choose the connection that supports your intended resolution and refresh rate, set a comfortable viewing height and tune the picture for the content you use most. High refresh output is most useful when your graphics card can deliver consistently high frame rates; demanding games may benefit from carefully balanced graphics settings.
Use the monitor controls or supported ASUS software to adjust brightness and picture settings for your room. Factory specifications describe the panel capabilities; application colour management, selected modes and input settings also affect the image you see.
