Paul,
I have a intel NUC and I am able to start mythfrontend without TV on.
My NUC goes through Marantz receiver and I suspect you also have it in a
similar way.
However, I do have another issue that I cannot start it from rexec
which runs without a tty. It simply hangs and does nothing.
So, I usually vnc to the machine with monitor/TV off and simply start it
on the X screen. I do not have issues starting this way.
I also have very similar situation with another frontend box that has
core i3-2100. My issue has been X starts in 4K each time I turn on the
TV and I had to xrandr to 1920x1080.120Hz.
Regards
Ramesh
