Overscan
— Press the navigation buttons to select the overscan value for each input
format. Choose between
0%
,
2.5%
, or
5%
. Set default overscan mode through SIS
commands (see the
Overscan mode
SIS commands on page 45).
Overscan is specific to each input signal type. This feature zooms and crops SMPTE input
resolutions to mask edge effects and ancillary data that are common in broadcast signals.
When the overscan mode is not at 0%, an Auto-Image on a SMPTE input rate (NTSC, PAL,
SECAM, 480p, 576p, 720p, 1080i, 1080p, and 2K [2048x1080]) refers to the default input
lookup table values instead of performing a “true” auto image.
NOTE:
Overscan is valid only on SMPTE input rates (NTSC, PAL, 480p, 576p, 720p,
1080i, 1080p, or 2K [2048x1080]) and is global for each video format.
Auto Switch
— Press the navigation buttons to turn the auto switch mode on or off, and to
set the priority. The auto switch setting allows for basic, unmanaged, input switching based
on the presence of active input signals. Auto switch mode options are:
•
Disabled (off)
•
Setting priority to “high to low” (highest numbered active input to the lowest)
•
Setting priority to “low to high” (lowest numbered active input to the highest)
Factory Reset
— Press and hold the
Enter
button until the message “Factory Reset” is
displayed over the OSD menu to clear all user settings but retain the current firmware. The
“Factory Reset” message is displayed over the OSD menu for 1 minute after the reset to
allow time for the display device to sync with the scaler output.
NOTE:
The Factory Reset is the same as performing the
ZXXX
SIS command (see the
Reset
command on page 47).
