detail and clarity. If set too low, the light areas will not be as bright as they could
be and it may be difficult to distinguish between foreground and background
information. Adjust so that whites remain bright but not distorted or tinted.
NOTES: 1) For best results, adjust brightness before contrast. 2) If environment

Adjusts the sharpness of the video image. Use or until the display is as
sharp as possible, keeping in mind that any level of detail above 50% will
increase the level of detail as well as introduce some level of noise in the image.
Set below 50% to filter the signal and remove noise from a noisy source. Keep at
50% to apply no detail.

Applies either a preset color temperature (3200, 5400, 5800,
6100, 6500, 9300) or a Custom or Interpolated color
temperature to the image. All are measured in degrees
Kelvin and represent the "coloration" (reddish or bluish) of
the whites displayed by the projector — the lower the
temperature, the more reddish the whites, the higher the
temperature, the more bluish the whites. Use the following
as a guide for most applications:
