.  We have to connect a computer up to the projectors.  The problem is that 
VGA does not put out a sync that the projectors can handle (ie ttl) We have 
purchased a device which converts the sync to analog but the device clashes 
with the convergance of the projectors.  The projectors have VGA inputs but
we would then need VGA boosters and VGA distroution amplifiers both of which 
are expensive and we have herd degrade the picture quality.
	Does anybody have a solution to this problem?  Does a video board exist
which produces NTSC sync in an RGB format?  Has anybody else had this problem?
Has anybody had to use VGA distrobution amps.?
	                             
					Thank you for your time
