A 4000dpi scanner is not a good way to said about the resolution quality of
a slide, a projector is a little better but also not the best way even you
have a very good lens. The best way is to use a 20x loupe or a microscope, I
have a Olympus microscope which serve for that purpose.

it's been shown that even a 4000 PPI scan won't *fully* resolve a 35mm
slide. Plus, you may introduce other variables, like film flatness and
scanner focus, that are bypassed when you project the original to a large
enough size, focus precisely, and take a very close look. In my experience
even the best scans don't come close to the effect from a nice, big
projection.
