Black Light applies visual effects to the screen by changing its gamma curve. You can invert colors, darken the screen beyond what's usually allowed, apply a color filter, or apply the 16-235 luminance gamut expected by some HDTVs.
What's new in version 1.7.1
Can now choose to apply effect to only one screen.
