Since HDMI is a digital signal, this would imply that signal on your line would cause a scrambled image. That means that the noise isn't coming in from the hdmi signal itself... it's either being fuzzed at the connector end after digital to analog translation, or the noise is being converted before the hdmi signal is being generated, and then sent to the monitor entirely...

Hmm. That's tricky. I'm curious to see where this goes.

I have a problem with some serious HDMI noise from the Overo FireSTORM /

I loaded a 16GB Class 10 MicroSD card with the Sakoman GNOME daily
build, booted several times at different resolutions, tried different
HDMI cables, connected to different monitors, and I've still got random
streaking and discoloration.

Can anyone tell me whether this is a hardware or software problem?
