The main, unsolved issue was getting the Samsung remote to also work as the cable box remote. Spent 2 full days working on that, to no avail. This will be the last Samsung TV I ever buy. It's back to projectors or industry display TVs for me.
Oddly enough (At least in my model) the ‘trigger’ to setup the universal remote is within the ‘input sources’ menu?
(And I still have to turn the subtitles on because I can't quite hear what the people on the TV are saying.)
