BRIGHTNESS UNIFORMITY —
screens already matched for their primary colors (see Adjust Primary Colors, above)
and overall light output, creating an exceptionally smooth screen in which no area of
the screen appears brighter and/or more red, green or blue than another. Selecting this
option activates the Brightness Uniformity menu, where you can enable the
"Uniformity Enable" checkbox and access a multitude of adjustments for critical
color light output control in specific areas throughout the image. Brightness
Uniformity settings are applied as long as the "Uniformity Enable" checkbox is
enabled and you are using the User 1 color temperature defined by the controls. To
disable the Brightness Uniformity function, delete the "Uniformity Enable"
checkmark.
Auto Power Up
Enter a check mark to enable the projector to automatically power up after losing
power due to a power failure or due to unplugging the projector during operation.
Note that unsaved display adjustments may be lost.

Diagnostics and Calibration

From the Diagnostics and
Calibration submenu you can
access several options for testing
and setup of images. You can
work with test patterns and
specific colors, freeze an image
for inspection, and/or access the
Odd Pixel Adjustment menu for
precision settings of offset and gain.
TEST PATTERN —
Refer to description under Geometry submenu.
COLOR ENABLE —
Refer to description under Image Settings.
FREEZE IMAGE —
Enter a check mark to freeze (stop) an image at a single frame.
This diagnostic tool is useful if you need to examine in detail a still version of the
incoming image that cannot be "frozen" at the source. For example, in moving
images it is sometimes difficult to observe artifacts such as external
deinterlacing/resizing and signal noise. Remove the checkmark to return back to
normal.
ODD PIXEL ADJUSTMENT
sources with Color Space set to
RGB only.
When using certain RGB sources
with still images, you may need to
adjust the normal gain or offset of
odd pixels in relation to even pixels.
This will smooth out very narrow
(1-pixel wide) "checks" or vertical
stripes that indicate adjacent "on"
and "off" pixels. You can remove these patterns as follows:
