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. Confirm that you are using an analog source not connected to
applicable for digital sources or sources going through the decoder. A grayscale is recommended.
4. If the blacks and/or whites appear OK, do not adjust input levels. If black levels are too high (and/or whites
are too low), you likely have a noisy source that is producing skewed input levels. Continue to Step 5.
5. Enable "Auto" in the Input Levels submenu. Wait for all 6 values to stabilize. Alternatively, do not use
"Auto"—reduce blacklevels manually instead. Change one or more of the six levels as necessary to obtain
proper blacks and whites. You may want to see only a color while adjusting—use the "Color Enable"
option.
6. Delete the "Auto" checkmark and leave the Input Levels menu.
Auto Color Enable
When a checkmark is present, selecting a specific blacklevel or drive to adjust will automatically enable the
corresponding color in the display. Delete the checkmark to see all colors.
Clamp Location
Brightens the image produced from some high-resolution high-frequency graphic sources. For most sources, the
best clamp location is automatically selected by the projector. 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 recommended for an HDTV source where the back porch is also short.
NOTE: Clamp Location is not used for video sources or any RGB source with sync information included on
the video (e.g., sync-on-green). Use Tri Level instead.
Color Enable
Select which color or colors you want to see in the display, useful while working with color temperature white
levels or input levels.
NOTES: 1) Input levels apply for the current source only, but for any color temperature used.
2) If color temperature is set up based on the internal test patterns, you can set up input levels for a given
source to match the color temperature of the internal test patterns.
Peak Detector
A method for defining individual input levels to improve the accuracy of input levels set by the Auto Input
level function. Enabling the Peak Detector activates an operating mode for detecting only pixels that are
considered black or white, all other levels are displayed as a mid-level gray. Using a smooth grayscale pattern
(where black and white are known to be at opposite edges of the image) adjust the individual blacklevels and
