•Verify that the cables are connected correctly.

•You might need to turn everything off and power up the equip- ment again. Make sure you power up in this order: projector, computer monitor, computer. It is especially important that you follow this sequence for Macintosh computers.

•Make sure your computer’s graphics board is installed and configured correctly.

If you’re using Windows 3.x:

1In the Windows Program Manager, double-click the Win- dows Setup icon in the Main program group.

2Verify that the Display setting is 1280x1024 or less.

•Does your computer have a compatible graphics board? The projector isn’t CGA or EGA compatible.

•Is your computer’s graphics output port turned on? This is especially true for laptop computers. See “Portable and Laptop Activation Chart” on page 49.
