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.
