That noise looks exactly like what I have when I use a bad DVI/HDMI cable with
a too high display mode for it. However, if changing TV settings changes the
pattern, and there is no pattern with the proprietary driver with exactly the
same mode, it seems like something else might be going on...

There is no HDCP used neither in NVIDIA proprietary linux driver nor in
nouveau. Even if there was, any "degraded picture" thingie would not be added
by the TV, but the video source, and it would simply mean a lower resolution,
not artifacts.

Sorry, I don't have any ideas.
