I'm really not sure of this, but:

Assuming your TV is DVI-A:

A lot of video cards now come with 2 DVI connectors and an adaptor to  
the HD DB-15 ("VGA") type connector.

I wonder if you could just put one of those adaptors on the TV's DVI  
connector and then use a VGA-VGA cable to connect to the video card.

The adapters are pretty cheap, and hardware junkies like me have a  
pile of them as you seem to get one with every video card these days.

Perhaps you could borrow an adapter and try it? Or buy one at RS or  
someplace for $5?

No guarantees of course, but it *might* work.

I know it made a HUGE difference when I started feeding my 32" LCD  
via the VGA connector as opposed to S-Video.
