Overview
The ASUS ROG Strix XG27UCMG is an 3840 x 2160 pixels / Ultra HD (UHD) / 4K / 2160p IPS monitor rated for a 48 Hz - 240 Hz refresh range. Response time is quoted at 1 ms GtG and 0.3 ms (MPRT) MPRT — the two are measured differently and shouldn’t be compared directly. On the picture-quality side, it’s specified at 400 cd/m² typical brightness, 1300 : 1 contrast and 130 % sRGB coverage. Tearing is addressed through FreeSync, G-Sync, VESA AdaptiveSync Display 240Hz. For hookups, there’s 1x HDMI 2.1, 1x DisplayPort 1.4, 2x USB-A.
