These are the basic steps to follow to display a single image over an entire wall of 
displays. Big Picture can be setup and saved for each video source, so you can 
switch between sources while maintaining the specific magnification and position 
settings for each source. 

 

Install the wall and attach source and power cables as 
described in earlier sections.  

Use an amplifier/splitter device (distribution amplifier) 
from the source or, if you are using loop-thru, use short, 
shielded cables to minimize noise and image jitter.  

In the menu for each display, select the source that will 
use Big Picture. If this is a computer source, use Auto 
for Mode selection. 

As described in Step 2, Step 3, and Step 4 in earlier 
sections, adjust black and white levels for each display; 
set phase and frequency; color balance the wall. 

Open the Wall Processor menu and make sure that the 
Wall mode feature at the bottom of the menu is not 
checked. Do this for each display. 

Set Zoom in the menu to the default width and height of 
800x600 or 640x480, depending on the Source and 
Mode. 

Find the edges of the image using the arrow buttons in 
the Position menu to move the image.  

For standard mullions, each mullion covers 3 pixels of 
the image and each button press in the Position menu 
moves the image one line or pixel at a time. Move the 
image so that 3 pixels on each side of the image are 
behind their respective mullions. For Ultra-Thin Mullion 
screens, one pixel should hide behind each mullion. 
When you move the standard size (not zoomed) image, 
if you find that more or fewer than 3 pixels (or one pixel) 
are hidden, then the optical image size needs to be 
adjusted. Do not Zoom the image to accomplish this.
