Hi Unga etc.

You might not have a FreeBSD problem as such, 
apart from what Polytropon & Warren Bloc suggest, also remember
your projector may not handle the resolution your screen is configured to.

Here's a true tale:
	I was giving a talk, called
		Free Alternatives To Microsoft
	Connected laptop 
	All black !
	Good natured audience heckled "So how does Micsosoft compare ?"
	Rebooted to Microsoft
	Still black !  Relief ! Duff hardware ! ... Der Hang on ...
	Both my MS-Win & My FreeBSD-X11 were in in 1600 x 1200 pixel mode.
	The projector couldn't handle beyond 800 or 1024
So drop out of X Windows, (Ctl + Alt + F1 )
See projector now works wth an 80 x 24 plain text screen
Go back to X	Ctl + Alt + Fsomething )

Retune your X config to a lower resolution the projector will accept.
	(I'll leave that for someone else to explain how please, tends to vary)
