Centering Adjustment
The three colors, red, green and blue, must converge for proper projection.
If you move the projector to another location, you have to perform the
centering adjustment.
The following are the procedures for using a built-in test pattern.
You can also perform the centering adjustment using an external test signal
without displaying a test pattern. To use an external signal, change the
CENT ADJ setting on the SYSTEM PRESET page. (See page 17.)
