What To Do If You See a Blank Screen
If you see a blank screen or a blue screen with the message No Signal
after turning on your computer or video source, try the following:
■ Make sure the cables are connected correctly, as described in
Chapter 1.
■ Make sure the power light is green and not flashing and the lens
cap is off.
■ Make sure you’ve selected the correct image source; see page 32.
Allow a few seconds for the projector to sync up after pressing the
button.

selected. See page 55.

CRT/LCD. Allow a few seconds for the
projector to sync up after pressing it. Check your laptop’s manual

On most systems, the or
CRT/LCD key lets you toggle
between the LCD screen and the projector, or display on both at
the same time.
■ If you’re projecting from a laptop, and you don’t see the same

monitor settings to make sure both the LCD screen and the
external monitor port are enabled.
From the Control Panel, open the

the settings varies by brand; you may need to click a
Monitor tab,
then make sure the external Monitor port is set as your primary
display and/or enabled. See your computer’s documentation or
online help for details.
