receiving a video signal.
• Check the video cable
connections.
• Check that the correct
video input is selected
on your projector.
• Make sure that your
projector is on and that
it’s connected to a power
source.
• If you’re using a laptop
computer, switch the
external video
connection on. Refer to
your laptop’s user’s
guide for more
information.
Your computer is in
standby mode.
Move the mouse or touch
any key on your keyboard
to bring your computer out
of standby mode.
Your computer is off. Turn on your computer (or
press your computer’s

on as usual.
The projected image is
blurry, too large or doesn’t
completely fill your
interactive whiteboard’s

aren’t adjusted.
Adjust your projector’s
position, zoom and focus
settings. Refer to your
projector’s manual for
more information.

match your projector’s
native resolution.
Consult your projector’s
manual for the correct
video resolution, and then
go to Windows Control

Preferences to change the
video resolution to match
your projector.
