A allows controlling of two display devices from one T

A output. Thus one UGX

is
able to control eight projection modules altogether. This is called
1×2 XGA settings
.
One graphics signal of T
RANS
F
ORM
A contains the display information for two projection modules with XGA resolu-
tion (1024×768 pixels), which results in a timing with 1024×1536 pixels. The graphics card connects just to one
of the projection modules; this module displays only its part and loops through the unchanged signal to the sec-
ond projection module, which displays the other part of the signal.
System requirements
The following conditions have to be met to allow 1×2 XGA settings:
•
The resolution of a projection module must be XGA (1024×786 pixels).
•
The projection modules must support 1×2 XGA settings with an input signal of 1024×1536 pixels and loop
through functionality.
•
Only projection modules which are positioned on top of each other can form a couple and use one graphics
channel commonly.
•
The graphics cards in T
RANS
F
ORM
A have to be UGX
G
RAPHIC
C
ARDS
•
In general the upper projection module is connected to the output channel of T
RANS
F
ORM
A; the lower projec-
tion module is connected to the loop-through output of the upper projection module.
•
If the display wall has an odd number of rows, then the bottom row does not use 2×1 settings and each
projection module of the bottom row has to be connected directly to an output of T
RANS
F
ORM
A.
Setup and configuration
For 1×2 XGA settings the cabling between T
RANS
F
ORM
A and projection modules must be considered. One graphics
channel of T
RANS
F
ORM
A is connected to the DVI in connector of the first module, the DVI out connector of this
module is connected to the DVI connector of the second module; please refer to the corresponding user docu-
mentation for the configuration of the projection module for 1×2 XGA setting. An example for the default cabling
is shown in the figure below:

cabling and graphics channels for 1×2 XGA settings
On the wall configuration tab the checkbox
1x2 projectors
must be enabled. One graphic channel, i.e. two mod-
ules on top of each other is depicted as one 3:4 array with a horizontal bar in the middle. The
Rows
and
Cols
boxes still indicate the number of projection modules.
