Help. I need serious help.Don't we all. My viewing distance for bum to panel will be about 8 foot. If I had the soon new to be Pv500 at 42" would the extra resolution give me an acceptable picture( i.e grain or not).Or would I be better of halving my Av bill and going with the acclaimed Pe50 Panny. Have read so many great answers form Hornydragon etc and would love some perspective on my dilemma(pardon the pun).
