Good thought.  It acts exactly like one of the video signals is creating a beat frequency against the 60Hz. line.  But, unfortunately tying another ground did not help.

I spent yesterday morning driving around to every local recycler and store who might have used LCD monitors.  Looked at perhaps 30 units - not one of which had an S-Video input.

My friend had a little 13" Sharp TV/Monitor with VGA, composite and S-Video, but it exhibits the same problem as the Samsung 730MW.  With his vast knowledge of things video, I wonder if Gene Heskett can decipher what's happening with these units?

My Samsung 214T provides a perfect display, but I really don't want to remove it from my audio editing work station.  eBay, here I come.

Steve
