3.4 Spreading One Picture Over a Wall

3.4 Spreading One Picture Over a Wall

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. When this is done correctly, the viewer does not notice the black lines separating the screens.

If you have not checked the optical engine alignment on each Margay, do so now. (See 3.1 “Adjusting Mar- gay’s Engine: Important Step” on page 38.)

Using an external processor

The processor divides a single picture into several sections and sends each part on a separate cable. Connect these cables to the proper Margay. You do not need the Big Picture key is this case.

You can still position the picture with the Margay controls, or, with most processors, position and zoom the picture with the processor controls.

Using Clarity’s Big Picture™

Each Margay must have a Big Picture key installed (“Installing the Big Picture Key” on page 12).

Loop the same source through all the Margays in a wall (“Connections, Control: RS232 & RS485” on page 28).

For each cube, set the Wall menu for the same wall size.

•Unit Column and Unit Row is the position of the Margay in this “wall.”

•Wall Mode, when checked, turns on the Clarity Big Picture™ feature. When not checked, the cube shows the whole picture.

Each cube in a “wall” gets the whole picture by looping the source from one cube to another, or be feeding them all with a distribution amplifier. The Wall & Aspect Ratio menu tells the cube what portion of the entire picture to display.

Scale Mode, Justify and Border Color…

…are explained in the next section, page 56.

•Wall Width and Wall Height are the number of cubes wide and high for the picture. This may be different from the physical wall size. You could build a 4x4 wall of Margays and use Wall Mode to put a single picture on the four cubes in the upper left corner, for instance.
