I find it easier to start with a dumb device. However as that increasingly looks not so possible for TVs, I'd love to see somebody document the process for what you propose.

you can still find some dumb displays if you search for "monitors" rather than "tvs".

Projectors are another option

Wal-Mart's Sceptre brand still sells a wide range of dumb TVs. Not super great performers, but also not expensive by any means.
