NOTES:
• The audio test outputs pink noise on the embedded digital audio output (2-channel,
48 kHz, 16 bit).
• All test patterns include a single pixel border (except Blue mode).
• All test patterns remain enabled after a power cycle.

saver time-out duration to a specified number of seconds.
When there is no active video on the selected input, the device can mute the video output to
black or blue for a set duration before disabling output sync. By default, the scaler outputs
black video and sync (no sync time-out) with no active input applied.
The time-out duration can be set to any duration from 0-500 seconds.
Auto-Image — Press the navigation buttons to turn the automatic per-input Auto-Image
mode on or off (default).
When enabled and a new input frequency is detected, the scaler first applies an existing
Auto Memory for the signal (if Auto Memory is enabled). If no entry exists, it performs an
automatic Auto-Image on the new signal. This sets a size and position for the image to fill
the screen, with respect to the current Aspect Ratio setting.
By default, the Auto-Image threshold is 25% brightness. Analog video signals greater
than the threshold are considered active video. To change the threshold value, use SIS
commands (see Auto-Image threshold value
Aspect Ratio — Press the navigation buttons to set the aspect ratio setting of the active
input to Fill (default) or Follow.
When in Fill mode, all inputs automatically fill the entire output. To adjust an aspect ratio for
a single input rate, set the desired size and center in the

saved and recalled the next time the signal is detected.
In Follow mode, each input rate is displayed with its native aspect ratio mode with the
correct letter box or pillar box settings visible.
The scaler clears the previous size and position settings whenever the aspect ratio setting
for an input is adjusted.
