Composite Display Noise

[Sprockett]

Has anyone had any luck reducing the noise going from the PI composite to the 3.5" monitor?

I tried wrapping it in thin foil, didn't make any difference, do I need a choke coil? (have to be a hell of a small one)...

Thanks

It's in Spanish, but someone pointed me to this project a while back -- they do some filtering on theirs. Been meaning to try it:

The filter they're using is to reduce the noise from DC power, not form the video source.
One idea that i has turning around would be to twist the connections, making a twisted pair. I don't believe itwill make a great difference, but I believe that some of the noise could be reduced.

Hah, that's what I get for not actually translating/reading it. someone had sent it to me a while back saying it would filter the composite signal.

I didn't think of the twisted pair, that's a great idea!

I'll try that tonight and report back, I'll also try it wrapped and unwrapped...

Thanks!!
