[mythtv-users] Are there any 4k themes for mythfrontend?

Since I have been using MythTV with my new LG C3 48" 4K TV for the
last couple of days, I have found an interesting problem.  The
slightly modified version of the MythCenter-wide theme that I am using
works OK at 3840x2160, but wastes a lot of usable space due to having
huge text.  At 1920x1080 on my old 32" 1080p TV, the text size was
good at my watching distance of 2.2 metres.  But now it is quite a bit
larger than it needs to be, and if it could be made smaller a lot more
data could be fitted on to the screen, such as many more recordings on
the recordings list.  But I have been unable to find any themes that
are designed for a 4K 3840x2160 screen size.  Does anyone know of any?

It looks like it would be quite a difficult job to modify
MythCenter-wide to work well at 4K, as virtually all the numbers in
the theme files would need to be altered in the right proportions. How
do theme designers do this sort of thing - is it just by tediously
going through all the files and manually making the changes and
testing them?

I also found that I had to alter the XFCE4 desktop settings to make
the desktop and terminals readable at that distance.  First I changed
the DPI setting to 200x200 in xorg.conf, so this is what I am using
now:

Section "Device"
        Identifier      "Nvidia GT1030"
        Driver          "nvidia"
        Option          "DPI"           "200x200"
        Option          "NoLogo"        "True"
EndSection

Section "Monitor"
    Identifier  "LG C3"
    ModelName   "LG Electronics LG TV SSCR2"
    DisplaySize 1050 590
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "LG C3"
        Device          "Nvidia GT1030"
EndSection

Section "ServerFlags"
        Option "BlankTime"              "0"
        Option "StandbyTime"    "0"
        Option "SuspendTime"    "0"
        Option "OffTime"                "0"
EndSection

Section "Extensions"
        Option "Composite"      "Disable"
EndSection

# For some reason X is unable to find the Nvidia drivers, so manual
paths
# are required.
Section "Files"
    ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg/"
    ModulePath "/usr/lib/xorg/modules"
EndSection

Then I also had to go to XFCE menu > Settings > Appearance > Fonts >
DPI and set a "Custom DPI setting" value of 200.

And on startup I am running this command:

xset s on

which turns on the builtin X screensaver with its default timeout of
600 seconds.  This screensaver will turn off the screen output if
there is no activity for that time, which will prevent OLED burn in
from having the mythfrontend menu screens displayed all the time.
