An X video application allows to display the sources connected to the input cards in individual windows on the
display wall.
The video windows are freely moveable (also across module borders) and can be scaled up and down.
In general downscaling of the data is performed by the input card, upscaling is performed by the

When displaying more than one video via graphic cards with analog output, the totally visible area of all videos
must be taken into account to calculate the frame rate. Due to transfer limits on the PCI bus other conditions
than mentioned in the table above apply for up-scaling of the videos.
In a system without OmniScalers, if the X server operates in 8 bit color depth only Module
