If you notice a decline in the projected image quality when the
image is displayed simultaneously on your laptop computer and
the projector, turn off the laptop’s LCD display.
■ If you’re projecting from a CVBS signal or Y/C signal source,
check the signal setting in the Signal menu. In most cases, leave it
set at
