it's your AV receiver most likely! Connect the Pi to the TV directly and report back on the results.Looked at these instructions for disabling overscan - the raspberry pi 5 running raspbian version 12 bookworm - doesn't show any way to select overscan settingPresumably over scan is on at the moment.
Info on how to change the setting:

Hopefully that's current enough.
I see someone else is having same problem with Rpi 5 and bookworm OS displaying correctly on TV screen
