This is a message the monitor displays when the video cable is disconnected or the computer has no video output. Could be the computer is simply entering power save mode. Does the screen come on when you move the mouse or press a key on the keyboard?

Usually means that the computer is not sending a signal out the the projector via the monitor cable. Most Windows based laptop computers allow you to connect to a second monitor by pressing the Fn + F7 or F8 key, once to allow just the projector, twice to allow both the projector and laptop screen and three times back to only the laptop.

ur monitor is "not" the problem... you have problem in ur PC..

solutions:
check loose graphic card
remove ram. put them back again/...

you may need to go into display setting and check that these setting match the ones for the projector
