Menu Descriptions & Functions
NOTE:
* When "Resolution" is set to "Native", "3D Reform", "Aspect Ratio" and
"Screen" are not available.
* If you are displaying an image with a resolution higher than the projector's
native resolution (i.e. 1024
ן768 for LT260/240 and 800ן600 for LT220)
and "Native" mode is selected in the menu system, the portion of the image
that lies off screen will be lost because of a change in the horizontal-to-
vertical ratio. This is due to the image having a larger horizontal resolu-
tion than the panels native resolution. This is not a malfunction and it can
be corrected using the 'Phase' adjustment in the menu system. After ad-
justing 'Phase', set the resolution mode to "Auto".
Selecting Overscan Percentage
Select overscan percentage (0%, 5%, 10% and 25%) for signal.
NOTE: When "Resolution" is set to "Native", this feature is not available, and
the stored settings and adjustments are invalid.
NOTE: When "4:3 Fill" or "Crop" is selected in "Aspect Ratio", this feature is
not available.
Selecting Video Filter Level (not available for Video, Viewer and LAN)
