3.4 Tiling a Display
Whether you use Planar's Big Picture™ or an external video processor, your goal is to make the picture fit
together properly at the edges.
Using an external processor
The processor divides a single picture into several sec-
tions and sends each part on a separate cable. Connect these
cables to the proper GX40.
You can still position the picture with the GX40 con-
trols, or, with most processors, position and zoom the pic-
ture with the processor controls.
Using Planar's Big Picture™
Loop the same source through all the GX40s in a wall
(See "Connecting Picture Sources" on page 13.).
For each unit, set the Wall menu for the same wall size.
To show the same source on all the GX40s in an array
you'll need to use an external distribution amplifier. For
41
each unit, set the Aspect Ratio & Wall menu for the same
array size.

Wall Width and Wall Height are the number of units
wide and high for the picture. This may be different from
the physical array size. You could build a 4x4 array of
GX40s and use Wall Mode to put a single picture on the
four units in the upper left corner, for instance.
• Unit Column and Unit Row represent the position of
the GX40 in this "array." For example, in the 4 x 3
array of GX40s shown below, unit numbering starts at
