Question about ASUS ROG Strix XG32WCMS 80.1cm (16:9) WQHD HDMI DP

The monitor has a resolution of 2560 x 1440 pixels, which is referred to as WQHD. It is not a 4K resolution, which is typically 3840 x 2160 pixels. The 4K resolution mentioned in your data seems to be an error, as the manufacturer's official specifications confirm a WQHD resolution.

makes sense, thank you
