Buttons needs freeper advice! I've never owned a tv, but I'm now looking to buy one. The choices are bewildering. I don't have or want cable, just a large screen (at least 40", and 70" is not too big). I watch a lot of videos on a laptop and with a large screen I could be less confined. The room is big, over 25' wide and long. Price isn't that important, quality is more of a concern. And which kind is best to view at different angles? It'd be good to see it properly no matter where in the room...
