Hi C.H. and all,

The limitation I find in scanners (at least, the models I have access to) is
shadow detail on slides -- or highlight detail on negatives. When you try to
brighten the shadows and only get noise (even at 16 bit/channel), there's
nothing the monitor could do.
Of course, the monitor may cause further limitation on DR of displayed
pictures.
However, I _think_ that using a camera for "scanning" the slides allows to
get much more shadow detail by using a much longer exposure -- at the
expense of highlights, of course. This way is possible to make some sort of
HDR pic from the same slide.
Cheers,
