6.1.12 Genlock
The refresh rate of the projection module is in general not synchronized to the refresh rate of the video. As a
result the display of the video can look jerky. Genlocking can avoid this unwanted behavior by providing the data
signals to the projector at a refresh rate which is perfectly adapted to one video source. A Source of a Q

Options of genlock
The actual state of the genlock utility is stored in the registry. Therefore after a reboot
automatically the same genlock settings as before are applied.
When using genlock make sure, that the cabling for genlock has been established as
explained in section
3.2.14 CPU board .
If an external signal is connected only external may be selected. If selecting internal or a
video signal it will be disturbed by the external signal. Therefore the external signal should
be unplugged before switching to an other type of genlock!
