Tracking, Lines until they disappear

Tracking	Matches the projector’s internal clock to the various
	computer graphics signals. If vertical lines appear within
	an image, adjust Tracking to spread the distance between
	the lines until they disappear.
Red	Adjusts the strength of the red level.
Green	Adjusts the strength of the green level.
Blue	Adjusts the strength of the blue level.
Text	Compresses the projected image to fit into the projector’s
	640-pixel image area. Normally you need to compress
	an image only if your DOS software program has a text
	screen wider than the projector’s area.
