I scan 35mm at 3200 dpi unless I am pretty impressed with the quality. In that case I scan at 6400 dpi.

I think that might have been the flat screen display. Unless it's a really new and expensive one, it has 1920x1200 or fewer pixels - that's 2mp. About the resolution of a big computer monitor (eg an Apple 27") except that the same data is spread across 50" instead of 27".
> It's just hard to tell without dragging out a projector
Most projectors are even lower resolution than that. Most are 1280x1024 or LOWER resolution... and there are still a pretty fair number of them around that are 800x600.
