Wan Mao monitors support 3840x2 160 60hz and 2560x2 160 144hz. The first two multiplication numbers are the resolution, and the second is the refresh frequency of the screen. The high refresh frequency is mainly due to no flicker, not resolution. If the general document resolution is set to 2560x2 160 144hz and the in-game resolution is set to 3840x2 160, then the frame rate should be only 60hz, not 144hz.
