I'm one of those who are sometimes irritated by the screendoor issue on my PJ. A common advice for alleviating this is to defocus the picture slightly. However, on my Sony Cineza VPL HS1 at least, when I defocus, the effect is skewed to one side. That is, I can't get the picture to be defocused by the same amount from left to right. Anybody have any thoughts on this?
