I have a Barco Graphics 801.


and there is a problem.


I use HTPC and input 1024*768 resolution image.


The projector accepts 1024*768 at any sacn rate (60, 75...)


and I chaged the resolution to 800*600....


But the projector can not accept it.


"No signal"lit up.


How can I fix it?


My 801 is out of order?


Pease help me. Please~

Sounds like a negative sync issue, older Barco's can be very fussy over BNC input signals - hook your HTPC up to a monitor and check that the video card is outputting negative sync ( - - rather than + + or - + in the display settings). Some video cards, Radeons for one will allow you to change the display settings to output negative sync. If your card does not allow this then use PowerStrip which does allow you to change the sync for any resolution on any video card.
