Can anyone explain 720 & 1080 in terms of actual resolution. When looking at the specs of panels they quote 2 figure together ie 852*480 Panny 1024*768 Pioneer. Neither seem related to 720 or 1080. On a similar subject I've read of a few folks running a scaler @ 720p into their Panasonic SD screens (852*480) and the picture really being improved. I dont get this as surely the screen must be trying to work out what bits to miss out in order for it to fit.
