Leave this setting 
On to automatically optimize the computer 
image. Turn it off if you want to save adjustments you have

matching the projector’s internal clock to various computer 
signals. See page 84 for more information.

out (best for fast-moving pictures). If you notice flickering 
while viewing still images, switch this setting to 
Off.
■Computer Input (1 or 2)
Selects the signal from equipment connected to the 
Computer1 or Computer2 ports. If your image colors look 
wrong, try changing this setting from

following: 
RGB for computer or RGB video sources, or
