Well, the specs for that monitor are at ....
https://uk.hardware.info/product/321689/samsung-t24e310ew/specifications
and other places.
They list the resolution at 1366x768 and you have it set to
1920x1080. Using an LCD monitor at anything other than its native
resolution is sure to give substandard results.
I suspect that the high-res computer screen copies somehow its
own resolution to the lower res TV. That's why I asked in another
message for the xrandr output for all three monitors, including the one
for the built-in computer monitor.
But it might be possible to force via xrandr some sane resolution to
an attached monitor.
So far I'm confident we'll catch that horse ... :)
