GG, here's one calculator: Viewing Distance Calculator

Just Google size of television for viewing distance & you'll get many websites telling you what size TV will be good for your room.

We have an LG LCD HDTV. The picture is great, but I was disappointed at how poor the sound quality was. I understand that's a common fault with these kinds of TVs -- not only the LG brand. We bought a sound bar, and now we can hear what people say much better.

I was also surprised at how hot the TV gets. I can feel the heat when I walk past the television.

Good luck with your new TV purchase!
