PI to Video Projectors

[SENGER at LAX.WISC.EDU]

I have a PI 4D/25. I would like to hook it up to an ElectroHome
video projector we have on campus. The video projector is model ECP-3000.
It has an RGB Sunc/10 Pin Module installed in it. I have been led to
believe that this should work, but I have had no success so far. The
projector seems to be unable to automatically sync to the signal. By
manually adjusting the horizontal sync I can obtain two side by side
images of the screen but this is not very stable.
 
Any help would be appreciated.
