I was looking to upgrade two very old Dell LCD panels and I'm very happy with these minutes. Price is great, and 144hz finally lets me run my RTX2060 above 60fps.
The initial color looked terrible, but before you go tinkering with brightness/contrast make sure your PC is properly detecting it. My PC initall saw the monitor as a 1080p HD display, instead of a 1920x1080 monitor. As soon as I selected the correct display type, the terrible brightness vanished an the display looked great. Only very minor brightness/contrast adjustments were needed for my environment, and also setting the monitor to game mode.
The display selection is only found in the NVIDIA control panel, not the windows display panel. I think a lot of people start messing with monitor settings without realizing the monitor is incorrectly detected.
