labeled either Y/Cb/Cr or Y/Pb/Pr), see “Connecting a 
Component Video Source” on page 23.
■If your video player has an RGB video port, see “Connecting an 
RGB Video Source” on page 24.
After connecting video cables, you may also want to connect an 
optional audio cable to play sound through the projector; see page 26.

note
Some LCD monitors may 
not be able to display the 
image correctly. If you have 
trouble displaying the 
image, connect a multiscan 
monitor. If you’re projecting 
computer images, make sure 
the computer’s refresh rate is 
set to 65 Hz or greater.
The projector must be 
turned on for the Monitor

a power switch that supplies power to the projector. You don’t have to 
wait for the projector to cool down first.
1. To turn off the projector, press the Ppower
 button on the remote 
control or projector.
You see a confirmation message. 
(If you don’t want to turn it off, 
press any other button.)
2. Press the Ppower button again. The projection lamp turns off 
and the projector beeps twice. You can then unplug the power

note
Lamp life will vary 
depending upon mode 
selected, environmental 
conditions, and usage.

of the projector. 
You can set the projector to 
automatically turn off the 
lamp and enter “sleep mode” 
when it has not received any 
signals for 1 to 30 minutes 
(see page 51). This conserves 
electricity, cools the 
projector, and extends the 
life of the lamp. If you want 
to start projecting again, 
press the P power button. 
If you are done using the 
projector, unplug the power 
cord.
