Hi: What exactly is the screen door effect? I had thought I knew, but I saw something while TV shopping, and now I am not sure... What I had thought SDE was would be seeing the black around a pixel, and every pixel. Very VERY small, but obviously an annoyance. Is this right? What I have seen when TV shopping is this (and I don't know what this is called, could this really be the SDE?) What it looks like are fairly large squares of color, maybe 1/10 or 1/20th the screen height. And they are square. Reminds me of a very compressed JPG image. In fact, that was my first thought- a digital signal, WAY too compressed. Could it be the source is split into too many TV's? Is it poor or over compression? Or are these TV's handling the signal poorly? Thanks for your help. BTW, I am figuring on getting the new Sony GW III. Yes, I know ALL the arguements... and I do like the look of the DLP's, but I see the rainbow. I like the blacks on this MUCH better than any other LCD.
