How to fix nVidia HDMI color issues
For the last few days, the colors on my Windows PC have been muted (e.g. what should be white was washed out) except for the mouse cursor which was still a vibrant, white.
As the video shows (for nVidia cards), create a new resolution and manually drop the screen refresh rate down from 60 Hz to 59.999 Hz.
