Auto Memory
— Press the navigation buttons to turn Auto Memory on or off for
each input. The scaler stores 32 auto memories per input, with input configuration
and picture control data for each video resolution. The default setting enables these
memories to automatically recall input and picture controls for previously applied
signals. When auto memories are disabled, the scaler treats every applied signal as a
new source.
Auto Memory and Auto-Image Interaction
Auto Memory Auto-Image
Information
On
On
New signals and rates not previously detected by the
scaler, are initially set up using default parameters, then
Auto-Image is automatically applied. The next time the
signal is detected, the values stored in the auto memory
location are applied.
On (default)
Off (default)
New signals and rates not been previously detected by
the scaler, are set up using default parameters. If manual
input or picture settings are made to the input, an auto
memory location is created and recalled each time the
input is detected.
Off
On
Each change in input sync, input switch, or power cycle
triggers an automatic Auto-Image. When auto memory
is disabled, each change in sync is treated as a new
signal and an automatic Auto-Image is triggered. Manual
changes made to the image and picture controls are lost
each time a new rate is detected.
Off
Off
Each change in input sync causes default values to be
applied. Manual changes made to the image and picture
controls are lost when a new rate is applied, a new input
is applied, or after a power cycle.

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 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-input switching 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 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 to reset the device to factory
defaults. The scaler retains the current firmware version, as well as communication and
IP settings.
