Anyone here compared these three projectors? There's a comparison here (near the bottom) http://www.projectorcentral.com/panasonic_pt_l300u.htm How does resolution affect the picture quality with these lcd projectors? The first two have 960x540 resolution and the sony has 1366x768. The review linked above (american site) is obviously biased towards either NTSC or HDTV so the 960x540 works well for them.. but what about PAL on a 960x540? Then again if it has to scale to fit then does having more lines help that much, if its not 1:1 then does it matter? Does anyone know much about internal scaling in units like this? An anamorphic 2.35:1 PAL dvd has unused lines at the top and bottom.. does something like the z1 know this and therefore use 1:1 to display it?
