Panel, Resolution and Surface

The 26.5-inch viewable screen uses Tandem RGB OLED technology with a true RGB stripe subpixel arrangement and a TrueBlack Glossy surface. Its 3840 × 2160 resolution brings 4K detail to the 16:9 display. ASUS lists 99% DCI-P3 color space and 10-bit display colors, with VESA DisplayHDR 400 True Black certification among the published specifications.

Refresh Modes and Response Time

Dual Mode offers 4K at up to 240 Hz or Full HD at up to 480 Hz. The resolution and refresh combination changes together, giving you a choice between native 4K detail and a faster lower-resolution mode. A specified 0.03 ms gray-to-gray response complements both options when the monitor is used with a compatible source and signal.

Motion Settings for Compatible Systems

Variable-refresh support works with compatible graphics hardware to adapt the display timing to the signal. Extreme Low Motion Blur is also listed among the gaming features. Treat the available motion settings as options to configure for your chosen mode, then compare their effect in the games you normally use before settling on your preferred display setup.

Connections for Your Desk

DisplayPort 2.1 with UHBR20, two HDMI 2.1 inputs and USB-C with DisplayPort Alt Mode provide the main video connections. The USB-C connection supports up to 90 W Power Delivery, and a three-port USB 3.2 Gen 1 Type-A hub is listed. Match the source and cable capability to the resolution and refresh mode you intend to use.

Position the Screen Around You

The stand offers up to 110 mm of height adjustment, tilt and swivel up to 30° in each direction. Pivot adjustment is also listed for changing the screen orientation. A 100 × 100 mm VESA mounting pattern provides an alternative when using a suitable mount. Check the published dimensions and weight when planning the screen position and available desk space.
