27" 180 Hz Fast IPS Gaming Monitor

The ASUS ROG Strix XG27ACS is a 27-inch QHD gaming monitor built around a Fast IPS panel with a 180 Hz refresh rate and 1 ms GTG response time. It covers 133 % sRGB and 97 % DCI-P3 colour spaces with a typical brightness of 350 cd/m² and HDR400 peak brightness of 400 nits. Connectivity includes HDMI, DisplayPort and a USB-C port delivering 7.5 W power. The stand offers ergonomic adjustments and an integrated tripod socket for accessories.

Suits competitive gamers needing high refresh

This display fits players who want smooth motion at 2560 x 1440 resolution with Adaptive-Sync support across both FreeSync and G-Sync Compatible modes. The Fast IPS panel keeps viewing angles wide at 178° horizontal and vertical. Buyers who need higher refresh rates for professional esports or wider colour volume for colour-critical work should consider other options.

180 Hz refresh rate with 1 ms GTG response

The single specification that decides fit is the 180 Hz maximum refresh rate paired with a 1 ms grey-to-grey response time. This combination determines whether motion clarity meets the demands of fast-paced titles at QHD resolution. If the target frame rate falls well below this ceiling, or if a faster panel is required, the monitor will not match the intended use case.
