Operation 14
Note: When you change the contrast (brightness)
control one step at the time (click per click), the
picture contrast (brightness) will change although
the cursor on the OSD does not move. This is
because contrast (brightness) can be adjusted in
more than 4000 steps, and the OSD is only 6
inches wide.
Advised setting for
contrast and
brightness
A fixed vertical dash in the OSD indicates the
calibrated value. This is the advised display
setting for optimum image performance and
consistency in a controlled ambient light
environment.
When you select the calibrated position, the
word CAL appears in the OSD.
How to use LUC
Luminance Uniformity Correction (LUC) is a
system that matches the luminance at the edge
of the picture tube to the luminance in the center.
As a result, the overall luminance is more
uniform.
LUC is switched on when the display is produced.
It can be switched off by a qualified technician.
For more details, please read Appendix A,
"Background information".
