The cable is probably more like 40 feet but it is a very good cable.  I
just measured the OD and it is half an inch or about twice the diameter of
a cheap HDMI cable. I have used this cable with this projector for at least
10 years and it works fine. It is important to drive it with enough power.
I have a splitter that I used to use that I am sure will drive it if I see
issues.  That splitter is a DVI splitter. If I wanted to go back to driving
the TV with 720p I would put it back in and see if it passed audio. At this
point, I will just move the cables manually unless someone knows of a
switch that will work.  We don't use the projector for Myth very often
anyway.
