NOTES:
1) Input levels apply for the current source only, but for any color temperature used. 2) Assuming that
color temperature has been set up based on the internal test patterns, you can then set up input levels for a given
source so that it matches the color temperature of the internal test patterns.
AUTO INPUT LEVEL
– Temporarily enter a checkmark only if you are an experienced user and you have an unusual
source that you feel needs further color temperature and/or input level adjustment. This compensates for
incoming out‐of‐range drives (white) and black levels (black) that would cause “crushing” of light and dark colors in
the image. After entering a checkmark, wait for the six slide bar values to stabilize, then delete the checkmark and
exit. The Auto Input Level is automatically turned off upon exit from the Input levels Menu.
BLACK LEVELS AND DRIVES
‐ To check your image and adjust these controls: Make sure overall “Contrast” and
“Brightness” settings are both set to near 50.
1.
NOTE:
Not required for “Auto” adjustment.
• Contrast = 50 (approx.)
• Bright = 50 (approx.)
2. Check the color temperature setup using an internal grayscale test pattern, making sure to obtain a neutral
grayscale.
NOTE:
Not required for “Auto” adjustment.
3. Certain input levels adjustments are not applicable for digital sources or sources going through the decoder.
4. If the blacks and/or whites appear OK, input levels do not need adjustment. If black levels are too high (and/or
whites are too low, which is rare), you likely have a noisy source that is producing skewed input levels. Continue
with Step 5.
5. Temporarily enable “Auto” in the Input Levels submenu. Wait for all 6 values to stabilize. Alternatively, do not
use “Auto” — reduce black levels manually instead. Judge by eye and change one or more of the six levels as
necessary to obtain proper blacks and whites. You may want to see only a certain color while adjusting — use the
“Color Enable” option (described below).
6. Delete the “Auto” checkmark and leave the Input Levels menu.
IMPORTANT:
Do not use Input Levels to adjust color temperature. This will distort Contrast and Brightness
functions as well as color temperature.
AUTO COLOR ENABLE
– When a checkmark is present, selecting a specific black level or drive to adjust will
automatically enable the corresponding color in the display. Delete the checkmark to see all colors, or to enable a
different specific color through the Color Enable Control.
CLAMP LOCATION
– This option (formerly known as sync tip clamping) can brighten the image produced from
certain high‐resolution high frequency graphic sources. The projector automatically selects the best clamp location
for almost all sources. Use the normal
Back Porch
location if the image is either sufficiently bright or overly bright.
Select
Sync Tip
if the image appears unusually dim, if there are horizontal streaks across the image, or if there is
significant color drift. This moves the clamping pulse from the normal back porch location (which is likely too short)
to the tip of the horizontal sync pulse. Tri Level is typically needed for an HDTV source.
