You can't really buy a big monitor, just buy a TV and don't use it as a TV.
If you're using an AV receiver then you can ignore sound (generally the flatter the crapper speakers) and that will also deal with switching all your inputs. Plug everything into the AV receiver and one cable goes from the receiver to the TV.
Most out of the box colour profiles are set up for brightly lit shops so are a bit crap. You can either set them up yourself, google to find a decent one or some have some decent ones hidden away (the THX profile on mine is decent for instance).
Panasonic are a decent brand. 4k is a bit unnecessary at the moment but it doesn't necessarily cost that much extra and it does seem to be getting more popular. It wouldn't be a make or break but it's a nice bonus.
