OPERATION
BLACKLEVELS AND DRIVES - To check your image and adjust these controls:
1. Make sure overall Contrast and Brightness are both set to near 50. NOTE: Not
required for “Auto” adjustment.
= 50 (approx.)
= 50 (approx.)
2. Check the color temperature setup using an internal grayscale test pattern, adjusting
as desired to obtain a neutral grayscale. NOTE: Not required for “Auto” adjustment.
3. Make sure you are using an analog source not connected to INPUT 3 or INPUT 4, as
Input Levels are not applicable for digital sources or sources going through the decoder.
A grayscale is recommended.
4. If the blacks and/or whites appear OK, input levels do not need adjustment. If the
image has poor blacks and/or white, continue with Step 5.
5. Temporarily enable “Auto” in the Input Levels submenu. Wait for all 6 values to sta-
bilize.
6. Delete the “Auto” checkmark and leave the Input Levels menu.
To adjust black levels and drives manually, judge by eye and change one or more of the six lev-
els 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).
CLAMP TIP - This option (full name sync tip clamping) can brighten the image produced
from certain high resolution, high frequency graphic sources. Enter a checkmark if the image
appears unusually dim, if there are horizontal streaks across the image, or if there is significant
color drift. Delete the checkmark if the image is either sufficiently bright or overly bright.
NOTE: The sync tip clamping option is not used for video sources or any RGB source with sync
information on the video (e.g., sync-on-green).
COLOR ENABLE - Select which color or colors you want to see, 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) 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 inter-
nal test patterns.
