I use the Functionality 31.2 theme on most of my PCs that run
mythfrontend.  In particular on my Den PC which displays on a 65" Sony UHD
4K TV, my face is 15ft from the screen. The Functionality theme has 4 hours
and 14 channels on one screen.

The distance makes the normal non mythfrontend text too small so I use a
3840x2160 screen resolution but with a 200% scale factor on the Display
setup of Cinnamon DE.  I'm using LMDE 6 Faye at the moment and it's still
X11, but I don't modify Xorg.conf.

However, since I change distros on this PC as much as I change my
underwear, I might be running Endeavour OS by tomorrow and that is Plasma
KDE.  I use the same resolution and scale factor, but since Plasma is now
Wayland I have to launch mythfrontend with:

mythfrontend --platform xcb

If I don't I get a 1/4 screen display for mythfrontend.
