Built around your game
Fast OLED response
A 0.1ms GTG response helps keep rapid transitions crisp. Up to 138Hz overclocked refresh and G-SYNC Compatible operation support responsive play when paired with a suitable graphics source.
Colour with depth
True 10-bit output, 98% DCI-P3 coverage and Delta E below 2 provide a capable foundation for rich game visuals. HDR10 supports compatible HDR sources, with individually controlled OLED pixels delivering deep black areas.
Comfortable brightness
The anti-glare micro-texture surface reduces distracting reflections. An optional uniform-brightness setting helps maintain a steadier desktop appearance as window sizes change.
Cooling and panel care
A custom fanless heatsink supports thermal management without adding fan noise. ASUS OLED Care settings help maintain the panel; leave maintenance features enabled for everyday use.
Connections and sound
Two HDMI 2.1 inputs, two HDMI 2.0 inputs and DisplayPort 1.4 DSC accommodate several devices. The integrated speakers and woofer offer convenient audio, while optical and headphone outputs serve external sound systems.
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.

Compatibility & important notes
- 138Hz is an overclocked mode; maximum resolution and refresh depend on the source, input, cable and monitor settings. HDMI 2.0 is listed for up to 60Hz.
- The included stand supports tilt but does not provide height adjustment. A mounting solution must support the 300 x 300mm VESA pattern and monitor weight.
- The 42-inch class screen has a 41.5-inch viewable diagonal.
- ASUS lists two-year warranty coverage including panel burn-in, subject to regional terms. Use OLED care and allow maintenance cycles to finish.
- The specification table follows ASUS's dedicated tech-spec page, including its 135,000:1 typical contrast figure; feature-page contrast figures may differ. Peak HDR brightness can vary after colour calibration.
