Adjusting Signal Settings
Although the projector normally detects and optimizes the input 
signal automatically, you can use the Signal menu to make manual 
adjustments. In addition to changing the position of the projected 
image, you can correct tracking and sync for computer images, or 
change the aspect ratio. 
1. Press the 
Menu
 button and select the 
Signal
 menu. You see a 
screen similar to one of those below. (The settings will be different 
depending on the source you are projecting from.)
Computer/RGB video
Component video
Composite video/S-Video
HDMI (EX5200/EX7200 only)
