To adjust, increase the drive level for a color that appears too weak in the
test pattern (i.e., one that is less than 73). Try not to reduce a drive, as low
settings can reduce overall projector brightness. Also keep in mind that
setting a drive level over 73 will limit the number of discernible grays and
produce an uneven color temperature across the grayscale.
NOTES: 1) Always try to achieve the desired effect by first increasing the
drive level for the color judged to be weak. If the drive level for that color
is already at 73, then decrease the contrast level for one or more of the
other colors. 2) If you want to adjust each color individually, you can
connect only one signal cable — red, green or blue — at a time.

When the grayscale appears as you want, select Return. You can now use
this temperature with the current source.

If "Auto" is checked, the projector will automatically
detect the video standard present and display this
standard in the adjacent box. If "Auto" is unchecked,
press
at the adjacent pull-down list to view or
select a different video standard from a complete list
available to the projector. Selecting a specific standard
forces the projector to process the signal according to
this standard. Re-check the "Auto" checkbox to return to automatic detection of
the standard.
NOTE: This option should remain set at auto for all instances EXCEPT: 1) a
poor quality input signal or 2) a black-and-white video signal. In order to detect
and display such signals, uncheck "Auto" and specify the relevant standard.
