Nice chart Afx, thanks for posting it. You would not believe how much misinformation there is out there on screen resolutions and screen sizes. I’ve gotten into arguments with people who claim at less than 50″ the human eye cannot distinguish 720P and 1080P. As your chart shows, this is rubbish as long as you are close enough to the TV.
FLU, as for your TV deal, the 2 46″ sets is better, as this is a later generation Sharp Aquos than the 52″ and 32″ combo. The 64 model (46″) was the first one not to be plagued with horizontal and vertical bands visible in some scenes. I actually own the 42″ version of this set, and let me tell you, it is incredible. I have my eye on the 65″ version ($3999 on at the NEX) for my living room after me move next summer.
