Getting a projector is a good option these days. They're cheap and can give you a home theater experience with easily twice that size. Just measured my setup and it ends up at ~130" diagonally.

There are limitations in the room you can use (not too bright, big white wall, good place to place the projector). But if you can manage it I strongly suggest it.

Want to vouch for the projector route if you aren't a total definitionphile.

I have a $80 one off Amazon with 4000 4.5 star reviews. Gives about a 8'x6' pic on my bedroom wall. Has all the inputs.

Eighty dollars!
