BNC Cable Interference

Tanuki · Post by **Tanuki** » 26 Nov 2009, 01:05

I use a BNC cable to output to my display. It is five pronged(RGBBW). This is the second BNC cable I have used and the second display that I have used with the BNC.

All of them have ghosting issues. I can get rid of them for a time by jiggling the connnectors, moving wires, removing and attaching, etc. but they will always come back eventually. Sometimes I can get it to last a few weeks sometimes I do not even have time to sit down before it is ghosting again.

Does anyone have any experience with using BNC connections in this way? Any suggestions for the problems? I cannot decide if it is the connections or the position of the wires that is causing the problems. I do know that at lower resolutions the problem is not there or at least undectable.

I am used to this by now but it is an annoying thing to deal with.

probibly poor impedence matching and or poor shielding on the cables...

does using VGA connection (if that is possible) exhibit the same problems?

VGa is fine. Monitor(s) are dual input. I was thinking of wrapping the cables in something, foil maybe.
