The ASUS ROG Strix XG27UCS Gen2 (XG27UCSR) is a 27-inch 4K UHD gaming monitor with a Fast IPS panel running at 160Hz, and a dual mode that switches to Full HD at 324Hz, made for gamers who want sharp 4K detail and fast esports response in one screen.
HDMI 2.1 supports 4K at 120Hz with VRR for PlayStation 5 and Xbox Series X, USB-C with DisplayPort Alt Mode connects a laptop with one cable, and the fully adjustable stand tilts, swivels, pivots and adjusts in height. Colour covers 95% DCI-P3 with VESA DisplayHDR 400.
