The 3440 x 1440 resolution adds horizontal space to the familiar 1440-pixel height. A gentle 1800R curve brings the edges closer to a centred seating position for supported 21:9 games.
A 0.03ms GTG response and 175Hz refresh support responsive motion. G-SYNC Compatible and FreeSync Premium Pro work with suitable graphics sources; ELMB adds an optional motion-clarity tool.
99.3% DCI-P3 coverage, true 10-bit colour and factory Delta E at or below 2 provide a strong colour foundation. DisplayHDR 400 True Black certification complements independently controlled OLED pixels.
OLED Care Pro includes protection settings and a Neo Proximity Sensor that switches to a black image when you step away. Customise detection distance and maintain the sensor for reliable operation.
AI Visual, Dynamic Crosshair and Dynamic Shadow Boost offer scene-oriented assistance. DisplayWidget Center makes supported settings available through a mouse-driven interface, with virtual screen and uniform-brightness options.
Two HDMI 2.1 inputs, DisplayPort 1.4 DSC and USB-C provide flexible source options. KVM supports shared peripherals, while 110mm height adjustment, tilt, swivel and Aura Sync help fit the monitor to your 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.
