I need to adjust the screen size on the display (TV), not resolution. There couple of OSes like Libreelec, Kodi, and windows with Nvidia adjustment.

These have GUI to adjust the corner to of screen to make sure it fits the entire display, TV. I have already tried some CMD line solution but they don't work well and the TV doesn't have any adjustment either for overscan/underscan.

So, there got to be linux distro which has this feature build it, right?

See attached examples from other Windows or non-desktop Libreelec/Kodi (linux).

I looked at a few solutions from this search.
Tried them on my own monitor.
I get the impression that xrandr's syntax has changed in the last years, but what you want should be possible with xrandr alone.
Maybe the --panning option is what you need to experiment with.
