I've been enjoying gamma set to 55-60% on a Display with norm to cool bightness/temps... Also use a Red Night light from Sportys pilot shop facing down on the Keyboard, adds to the immersion and helps the eyes. Only thing is I wish the entire HUD/TDC was red illuminated or green too. It's hard searching the horizon with your nose to the screen and having that bright TDC glow in your eye's ( so I hit NUM+DEL ) to remove it until ready for a firing solution.
