Overview

A 26.5-inch WQHD QD-OLED gaming monitor built for competitive players who need 240Hz speed, 0.3ms response, and factory-calibrated color accuracy.

QD-OLED Panel Performance

The Samsung-manufactured QD-OLED panel combines self-emissive pixels with quantum dot technology for true blacks and vivid colors. It achieves a 1,500,000:1 static contrast ratio and covers 99% of the DCI-P3 color space. HDR10 support and 400 cd/m² peak brightness make highlights pop in supported content.

Competitive Gaming Speed

A 240Hz refresh rate at WQHD resolution pairs with a 0.3ms gray-to-gray response time to minimize motion blur and ghosting. ASUS ELMB technology further sharpens fast-moving images. Adaptive Sync works with both FreeSync Premium and G-Sync Compatible GPUs for tear-free gameplay.

Ergonomics and Connectivity

The stand offers 110mm height adjustment, -5° to 20° tilt, ±45° swivel, and pivot for portrait orientation. Two HDMI 2.1 ports and one DisplayPort 1.4 connection support 240Hz on PC and current consoles. A 3.5mm headphone jack is included, and the monitor mounts to 100x100mm VESA arms.
