Cuts ("bias" "low") are the low level grayscale controls. Gains ("drives" "high") are the high level ctrls.
A display set up for a showroom with Brightness and Contrast too high, and color temp too blue.
Contrast is the white level control that affects highlight detail.
Brightness is the black level control that affects shadow detail.
Tint rotates the hue of the display. We normally think of Tint as Blue rotating toward Red and Green.
Brightness controls the back level.
Color and Tint are difficult to set by eye (you need special glasses), and gray scale is impossible.
CRTs lose blue, UHP DLP sets lose red, plasma has image retention, LCDs fade slightly.
If you are concerned about screen damage, use the counterweight mount or a tripod for placement.
