Asus ROG Strix XG27ACMS - 27" - 320Hz Gaming Monitor

Blistering 320Hz Speed Meets Stunning WQHD Clarity

The ROG Strix XG27ACMS is built for players who refuse to compromise on speed or image quality. A 27-inch Fast IPS panel runs at WQHD (2560 x 1440) resolution and pushes an overclocked 320Hz refresh rate with a 0.3ms (min.) response time, so fast camera swings and rapid gunfights stay crisp and free of smearing. HDR10 support paired with VESA DisplayHDR 400 certification adds brighter highlights and deeper shadow detail for a more lifelike picture.

Underneath the panel, ASUS layers in serious motion-clarity tech: Extreme Low Motion Blur Sync works alongside variable refresh rate support, while compatibility with NVIDIA G-SYNC and AMD FreeSync Premium keeps screen tearing and stutter out of the picture across a wide range of frame rates. ROG's Gaming A.I. suite adds Dynamic Crosshair for sharper aim tracking and Dynamic Shadow Boost to brighten dark corners without blowing out bright scenes.

Connectivity is equally well-rounded, with USB-C (DisplayPort Alt Mode plus 15W power delivery), DisplayPort 1.4, and HDMI 2.1 covering PCs, laptops, and modern consoles alike. A fully adjustable stand with tilt, swivel, pivot, and height control, plus VESA 100x100mm mounting and a built-in tripod socket, rounds out a setup that's as flexible as it is fast.
