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
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)
