Panel, Resolution and Surface

The 34-inch Tandem RGB QD-OLED screen combines a 3440 × 1440 resolution with a 21:9 format and an 1800R curve. BlackShield anti-reflection film forms part of the surface design. ASUS lists 99% DCI-P3 color space, 10-bit display colors and VESA DisplayHDR 500 True Black certification, giving this ultrawide a distinct specification within the ROG range.

Refresh Modes and Response Time

A maximum 360 Hz refresh rate and specified 0.03 ms gray-to-gray response complement the ultrawide resolution. The published signal ranges list up to 360 Hz for DisplayPort, HDMI and USB-C. Use a compatible system and connection for the intended mode, then configure the game and operating system around the resolution and refresh combination you want to run.

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 connect compatible sources. USB-C offers up to 90 W Power Delivery, with a three-port USB 3.2 Gen 1 Type-A hub and an earphone output also listed. KVM functionality adds another option when planning the display as part of a multi-system desk.
