What the ASUS XG27UCS computer monitor 68.6 cm (27") 3840 x 2160 pixels 4K Ultra HD LCD Black is worth

The ASUS XG27UCS is a 68.6 cm (27 inch) PC monitor with a Fast IPS panel, 3840 x 2160 pixel resolution (4K Ultra HD), in 16:9 format. It offers a maximum refresh rate of 160 Hz and a 1 ms response time, with NVIDIA G-SYNC and AMD FreeSync compatibility.

Its fluidity (79/100) and responsiveness (90/100) scores sit clearly above market medians, driven by the 160 Hz refresh rate and 1 ms response time. Brightness (83/100) also exceeds the median thanks to its 400 cd/m2 typical output. Colour score (20/100) remains low, however, as the number of displayed colours is below the market median. The overall score is 68/100.

The monitor includes a height-adjustable stand (12 cm), pivot, tilt and swivel functions, a USB type C port with power delivery up to 15 W, HDMI 2.1 and DisplayPort 1.4.

This monitor suits gaming setups where fluidity and responsiveness matter more than colour accuracy, particularly with a recent graphics card compatible with G-SYNC or FreeSync.
