Displaying a computer image Remove the lens cap.
Press the Pow e r button on the top of the projector or the remote.
The LED flashes green and the fans start to run. When the lamp comes on, 
the startup screen is displayed and the LED is steady green. It can take a 
minute for the image to achieve full brightness. 
? No startup screen? Get help on page 15.
Turn on your computer.

turn the external display on and off. Refer to your computer’s documenta-
tion to learn your computer’s key combination. 
? No computer image? Try pressing the Auto Image 
button on the keypad. Get help on page 15.
