I find a lot of youtube content is 60 fps, as is much of the content I
have on mythtv so due to my video card not having HDMI 2.0, I run at
1080p at 60Hz rather than 2160p at 30Hz.  Maybe someday I will update the
video card to fix that, although none of the mythtv content needs 4K.

X annoyingly thinks that when it detects the TV, it should run at 4K at 30Hz
rather than the explicitly configured 1080p at 60Hz.  This happens every
time I change inputs on the TV.

Well 24 unless you are in europe where they run the movies 4% fast when
shown on TV.  Shown 0.1% slow on north american TVs.
