So I figure since I had replaced everything else in the room, got myself a new Ames Chair, couch, carpet, and tables, I thought it was about time to update and upgrade the audio/visual department of the room. The room is my general purpose room, TV, games, and movies. I thought I'd run the plans by you guys, since I don't know much about TVs and such. Here is a sketch of the room. It is a 15x10 room, that has old built in wood bookshelves. I am planning to purchase a Panasonic Viera TH-42PZ800U for the room, and I will have a 360, HDTV Cable Box, and PS3 plugged into it. They will all be connected to the TV via HDMI. I am planning on getting some sort of surround sound, either a traditional system or a soundbar. I was wondering what yall thought of this set up. I also was wondering if an AV receiver would be necessary/recommended for this set up. Sorry for all the questions, but I am new at this.
