I am purchasing a 70in Sharp 733u and I was wondering from other people on here that have TV's of this size how far back they sit from the TV. I know about the charts and I checked says a good distance is between 9 and 10 ft. I have a 52 now and that is how far i sit currently. Just want to see if anyone has had it at a distance and changed ether closer or more further back. Just wondering the set up that other people use with a 70 inch set thanks!
