These buttons switch the display between the video source(s) and the computer source(s).
If a projected image fails to appear, see the next section for help.
Once you see your image, turn to page 44 for instructions on focusing and making other image adjustments.
When you’re done with your presentation, shut down the projector as described on page 58. Shutting down the projector correctly prevents premature lamp failure and damage to the projector from overheating.
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, do one of 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.
■If you’ve connected more than one computer and/or video source, you may need to press the Computer or Video button on top of the projector to select the correct source. (Allow a few seconds for the projector to sync up after pressing the button.)
■Try restarting your computer.
