On rare occasion, you can experience
LOS
(loss of signal) — typically due to a poor video,
graphics or computer connection. In these cases, Encore obeys a precise set of rules:
•
Scaler LOS
— If there is a LOS for a video signal inside a scaler (PIP or KEY),
the video switches to black, but the scaler remains in its current size and position.
•
Background LOS
— If there is a LOS for a background DVI input, the video
switches to the background’s selected matte color.
•
DSK LOS
— If there is a LOS for the DSK, the system switches the DSK
Off
(specifically, selecting "
none
" as the type).
In each case, when the video signal recovers, Encore re-enables the signal as before.
S
In a widescreen setup, a multi-head graphics card is attached to the unscaled
BG A
channel. Once this live background source has been set up, if the
signal becomes invalid (e.g., if a cable is removed or the computer is turned
off), the
BG A
background switches to the currently defined
matte
color.
Refer to the "
Setting User Preferences
" section below for additional related information.

On the
Black Invalid Video
line, select the method by which the scaler “loading”
procedure is shown on Preview, when you change inputs:
~
ON
— black is shown when scalers are loaded. In addition, Black is
shown when a background channel (
BG
) becomes invalid, and the DSK
is turned off when source video becomes invalid.
~
OFF
— the full scaler loading procedure is shown. In this mode, the
Preview image can temporarily include non-sync and non-stable video.
