Fix poor (washed out) image quality in VLC

No doubt VLC is the best video player there is. However I experienced poor image quality (dark washed out) on several computers on which I installed VLC and had a hard time trying to tweak the video effect settings to no avail.

Turns out the problem happens only on NVIDIA video cards, and the solution is amazingly simple:

1. Go to Nvidia Control panel
2. In Nvidia Control Panel select adjust video color settings
3. In How do you make color adjustments? Select with Nvidia settings.
4. Select advanced of Nvidia video settings
5. Select FULL(0-255) in dynamic range.
