Can you access the system over the network and see if
there is anything in the system log?
It sounds like the display stack has crashed, but when the
sound keeps playing the system is most likely still
responsive over network.
Thanks,
Christian.

What happens is this simple: after a few minutes,
about 6 or so, the entire content of the screen stays
still. In some minor situations only the applications
panel of KDE Plasma.
If music is playing it continues playing, so only
graphics are hung. Yet in most cases the power button
won't shut down the computer, as it usually does.
At least this is the case using kwin on x11, and
not on wayland. It only happens on "radeon" and not on
Intel or "radeonhd".
Correct, but a TV is intended for videos only.
That's why it implements only the lower HDMI
standard.
Interlaced transmits only halve the lines with each
frame, so a 60Hz mode effectively either becomes a
30Hz mode, halving the vertical resolution or
adaptive motion compensated which the know visual
artifacts. Depending on what the deinterlacing
setting on your TV is.
You could just add a progressive 1920x540@60 or
1920x1080@30 mode manually and would have the same
effect with probably better quality. See https://de.wikipedia.org/wiki/Deinterlacing
for reference.
If you can give us some more information what is
happening when the system freeze we could try to
narrow this down, but we can't spend much time on a
very specific use case in a driver which is in
maintenance mode.

24fps is intended for video only. Anything
interactive at 24fps, as just moving the mouse
around, is extremely choppy.
No way anyone would prefer that over an
interlaced resolution or a lower resolution.
That is, by far, the worst option.
Just try it on your screen, set it to 24Hz
or alike, and tell me your experience. You
can't even tell where the mouse is going to
go.
Interlaced resolutions
are not used any more
on modern hardware, so
they
are not well tested.
