3.3 Tiling a Display
Whether you use Clarity’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 Bay Cat X.
You can still position the picture with the Bay Cat X controls, or, with most processors, position and zoom the picture with the processor controls.
Using Clarity’s Big Picture™
To show the same source on all the Bay Cat Xs in an
array you’ll need to use an external distribution amplifier. For 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 Bay Cat Xs and use Wall Mode to put a single picture on the four cubes in the upper left corner, for instance.
•Unit Column and Unit Row represent the position of the Bay Cat X in this “array.” For example, in a 2 x 3 array of Bay Cat Xs, the unit at the top left corner of the array would have a Unit Column value of 1 and a Unit Row value of 3
•Wall Mode, when checked, turns on the Clarity Big Picture™ feature. When not checked, the unit shows the whole picture.
✎Each unit in a “array” gets the whole picture by feeding them all with a distribution amplifier. The Aspect Ratio & Wall menu tells the unit what portion of the entire picture to display.
Frame Compensation
When video units are used in an array, the intent is to display a large version of an image. However, even the thin- nest of mullions break up the image oddly.
