--- Comment #23 from Joseph Yasi <joe.yasi at gmail.com> ---
I tried the patch, and I could still reproduce the issue. I don't really think
it's signal degredation.

Denon finally replied. They think it's an EDID negotiation issue between the TV
and the HDMI repeater in Denon, and suggested I contact Panasonic for a
firmware update. Since this is not a problem with other devices or the PC
connected directly to the TV, and I can also get it to happen with a different
4K monitor attached to the Denon, I doubt Panasonic could fix this. It's
probably a reclocking issue at high bandwidth on the HDMI repeater in the
Denon, and I don't really have a workaround except buy a new receiver.

I'm not sure Intel can to anything here, so feel free to close the bug.
