Every laptop computer has multiple display modes combining display on the laptop screen, out the external video port or out an external RCA TV jack If the computer is not set in a mode that displays an image out of the external video port, then there will be no image on the screen There is usually a key combination that will toggle between the different display modes Look for a key (usually one of the function keys) that has a picture of a display or the letters VGA on it You usually have to hold a special Function key (usually labeled Fn) and press this key to switch between the different modes After you press the key combination, wait at least five to ten seconds for the new setting to take effect before you toggle to the next setting.

Problem #2 Cables Loose

It is amazing how many display problems are caused by loose cables between the computer and data projector Make sure all cables are securely connected to the appropriate port with the thumbscrews used to secure each end of the cable to the port on the equipment.

Problem #3 Projector Input Source

On data projectors that are often used with TV and computer input sources, the input source selected on the data projector may still be in the TV mode and not in the computer mode There is usually a button on the top of the projector which allows you to toggle between the different input sources You may have to go into the data projector menu to change the input source on some older projectors
