I started another thread asking about the PE7700, but I also need some general advice on projector buying, since I'm new here. First off, since projectors have native resolutions comparable to TV's, is there a loss in picture quality from blowing the image up to larger proportions? Or is this generally only a problem for viewing low resolution source material on a higher resolution display? And someone told me that viewing SD source material on a HD screen/projector,can make the image appear worse than on a SD screen/projector of the same size/resolution. Is this true? And I asked this in the other thread as well, but it's still relevant here: do European model projectors usually support RGB input via SCART? Thanks in advance for any help guys!
