I have what I think is a simple question: What is the primary difference between a plasma with square vs. rectangular pixels? I am asking this question because of another post that I saw on this forum. Basically, one of the plasmas that has peaked my interest is the Panasonic 42PHD7UY. This plasma has a resolution of 1024 X 768, which I think is the perfect resolution for displaying a PC signal. However, I saw on another post that this display isn't good for computer signals because it has "rectangular" pixels! I'd appreciate any feedback as to "why" it may be true that rectangular pixels are bad?!?...........I don't get it?!? Which plasmas have square pixels and are square pixles better?!?
