The separate-screens mode allows displaying multiple screens on multiple display walls and single projection
modules. Nevertheless it is required, that the pixel resolution of each projection module that is used to display
the different screens is identical.
To use separate-screens the keyword SeparateScreens must be written in a line of the geometry section. As
with contiguous-screens each following line contains the information of one screen, but the position must not be
indicated.
With separate-screens the cursor is first displayed on screen 0. Moving the cursor out of screen 0 to the right lets
the cursor enter screen 1 on the left side. It will enter screen 1 on the same ratio of height as it has left screen 0.
This can be continued until the screen with the highest number displays the cursor. Moving out to the right usu-
ally brings the cursor again on screen 0. This can be prevented by the keyword NoCursorWrap. This keyword
can be inserted in any single line of the geometry section.

video
This section starts with the keyword video. The system stores in this location the configuration of the logical
video channels of a distributed system. Please refer to section
video channels. The video section must not be changed manually, but by means of the script EOSconfig, see
section 3.4.3 Configuring a distributed
way you have to specify the configuration in EOSconfig. Therefore you find here an instruction about it.
The syntax of the video section is as follows:
•
For each rendering machine, there must be a single line starting with the rendering machine's name: e. g.
engine-1.
•
In this line the video adapters of this rendering machine must be listed. The position where the entry of an
adapter is located defines the corresponding video channel.
•
The first position in the line corresponds with video channel 1, the second position with video channel 2 etc.
•
The entries in one line are separated by a space.
•
If no video adapter of that rendering machine uses a particular video channel, then a 0 has to be in that
position.
•
If multiple rendering machines have an entry for a video adapter at the same position, this means that these
adapters form together a logic video channel.
•
There might be blank lines and comments starting with a # character for better clarity. It is e.g. helpful to
have a commented line that lists the available video channels and makes the positions for the video adapt-
ers more obvious.
You may not mix adapters of input cards of different type to one logic video channel.
Dual RGB Input Cards may not be used to set up a logic video channel.
By default the video section is empty and a standard assignment is applied, see section
This standard assignment numbers the individual video adapters in the order of the PCI slots, beginning in the
