time-out duration to a specified number of seconds. These options can also be set by
using PCS software.
•
When there is no active video on the selected input, the device can mute the video
output to black (
Black ), or set it to blue with an on-screen display ( Blue with
OSD ) for a set duration before disabling output sync. By default, the scaler outputs
black video and sync (no sync timeout) when no active input is detected.

The screen saver timeout duration can be set to any duration from 0-500 seconds.
The default timeout value is 501, which disables the timeout.
• Aspect Ratio — Press the navigation buttons to set the aspect ratio setting of the
active input to Fill (default) or Follow.

In Fill mode, all input signals automatically fill the entire output. To adjust an
aspect ratio for a single input rate, set the desired size and center in the
Picture
Controls submenu (see Picture Controls submenu on page 32).

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.
• Auto Switch — Press the navigation buttons to turn the auto-switching mode on or
off, and to set the priority. The auto-switching setting allows for basic, unmanaged,

Details about each mode are available in Auto-Input Switching on page 27.
