Genlock - Barco Argus User Manual

6.2.11 Genlock

The refresh rate of the projection module is in general not a multiple of the refresh rate of the video. Therefore
when displaying video, in regularly intervals one frame of the video drops. This leads to a jerkily display of the
video. Genlocking can avoid this unwanted behavior. It causes the projection modules to adapt their refresh rate
to the refresh rate of one video source. Sources of Q

Genlock is controlled by means of the command line tool genlock. To use it open a command prompt and en-
ter the genlock with the respective options, like e.g:
C:>genlock /sel:frg0

The following options are available:
Option ption
/start
/sel:[<FRG-name>
|EXT|INT]

automatically the same genlock settings as before are applied.
When using genlock make sure, that the cabling for genlock has been established as
