I finally purchased a 144hz monitor (ASUS ROG Swift PG279QZ ) and it seems to run fine when gaming (only tested about 15mins). However, when I'm watching regular videos, the screen starts flickering. When I change the hz down to 60hz, the flickering goes away. Is this something normal or is my monitor defective? I'm using an RTX 2080 with the latest nVidia Drivers 417.71. Any help is appreciated.
