ASUS ROG Strix 27 4K HDR Gaming Monitor XG27UCS - Smooth 160Hz 4K

In this review the ROG Strix XG27UCS is presented as a 27-in 4K gaming monitor aimed at players who want high resolution and fast motion handling without stepping up to niche professional panels. The bottom line: it pairs a sharp 3840 x 2160 UHD image with an ultrafast 160Hz refresh rate and a 1ms Fast IPS response to deliver fluid, detailed visuals for competitive and immersive play, with added convenience from a USB-C connection and DisplayWidget control.

Key Features

• 4K UHD resolution: The 3840 x 2160 panel delivers dense detail for games and desktop work, making textures and UI elements look crisp at 27 in.
• 160Hz refresh rate: A higher-than-typical refresh rate for a 4K monitor that improves perceived motion clarity and responsiveness in fast-paced titles.
• 1ms Fast IPS response: ASUS Fast IPS technology reduces ghosting at high frame rates so fast motion remains sharp during action scenes.
• ELMB SYNC compatibility: Extreme Low Motion Blur Sync can run together with variable refresh to cut both tearing and motion blur for clearer frames.
• Wide color and tracking: 95% DCI-P3 with ASUS gray-scale tracking delivers richer colors and smoother gradation for games and content.
• DisplayWidget and USB-C: Built-in DisplayWidget Center and a USB-C connection make on-screen adjustments and modern connectivity straightforward.

Who It's For

The XG27UCS suits competitive and enthusiast gamers who want the clarity of 4K without sacrificing refresh rate and response time, and who run a capable GPU that can take advantage of 160Hz. It is also a good match for creators who value wide color coverage and smoother gray-scale tracking on a mid-size desktop screen.

Those who primarily need extreme brightness for HDR mastering, a larger ultrawide field of view, or an ultra-high-end professional color grade workflow may prefer other specialist monitors. Casual users who never exceed 60Hz and prioritise price above performance should consider simpler 4K displays.
