27-inch Full HD 380Hz gaming monitor

The ASUS ROG Strix XG279CNS is a 27-inch Full HD gaming monitor built for competitive players who value motion clarity. Its Fast IPS panel delivers a 380Hz refresh rate and a 0.30ms gray-to-gray response time. Adaptive Sync support covers both FreeSync Premium and G-Sync Compatible modes. The flat anti-glare screen targets esports enthusiasts who prefer high frame rates over pixel density.

380Hz overclocked refresh rate

The single specification that decides suitability is the 380Hz maximum refresh rate, achievable via overclock on the 1920 x 1080 panel. This figure determines whether the display can match the frame output of high-end GPUs in fast-paced titles. Buyers whose systems cannot sustain triple-digit frame rates at this resolution will not utilise the panel's primary advantage. The 16:9 aspect ratio and 0.311mm pixel pitch remain fixed regardless of refresh configuration.

Sustained 400 cd/m2 brightness with HDR400

Under continuous load the monitor maintains 400 cd/m2 peak brightness, meeting the VESA DisplayHDR 400 certification baseline. The 1,000:1 contrast ratio and 110% sRGB colour volume are stable during extended sessions, while the 16.7 million colour depth does not shift. Power draw settles at 20W typical, with the USB-C port limited to 7.5W delivery so connected peripherals cannot charge rapidly during long matches.

Questions about this item

Will this monitor run at 380 Hz over HDMI 2.1?

The 380 Hz refresh rate is achieved via the DisplayPort 1.4 connection; HDMI 2.1 supports the panel but may not reach the overclocked maximum.

Does the USB-C port deliver enough power to charge a laptop while gaming?

The USB-C port supplies 7.5 W via DP Alt Mode, intended for phone accessories or low-power devices, not for charging a laptop under load.

Is the stand removable for a 100 mm VESA arm?

Yes, the quick-release stand detaches and the monitor has a 100 x 100 mm VESA mount for third-party arms.
