Asus ROG Strix OLED XG27ACDMS - 26.5" QHD 280Hz Gaming Monitor

QD-OLED Speed Meets Precision Color

The ROG Strix OLED XG27ACDMS pairs a 26.5-inch QD-OLED panel with QHD (2560 x 1440) resolution, delivering sharp visuals and rich detail across a wide 16:9 viewing area. A 280Hz refresh rate and a 0.03ms gray-to-gray response time keep motion locked in during fast-paced gameplay, while input lag stays minimal thanks to the panel's near-instant pixel response.

HDR10 support and peak brightness of up to 1,000 cd/㎡ bring impactful highlights and deep contrast to compatible content. A 1,500,000:1 contrast ratio and true 10-bit color depth allow over a billion colors to be displayed with color accuracy rated at ΔE≦2, while an anti-reflective coating and 178° viewing angles keep the image consistent from nearly any position, making this monitor equally suited to competitive gaming and color-critical creative work.

Adaptive-Sync and VRR support reduce tearing and stutter, with G-SYNC compatibility for NVIDIA setups and Extreme Low Motion Blur for extra clarity during rapid movement. AI-assisted features like Dynamic Crosshair and Dynamic Shadow Boost help with visibility, while TÜV Flicker-Free and Low Blue Light certification support longer, more comfortable sessions.
