Thank you for the suggestions on specific models.
The meaning of the terms 'contrast' and 'contrast range' are well
established in the history of photography, and are inverse to one
another. Any photography manual will tell you that high contrast is
produced by having a low contrast range. Kodachrome looks more snappy
than BW negative because it has more contrast, but the later has more
ability to capture detail.
Neither term refers to the ability of the medium to reproduce a black
that is actually black and a white that is actually white, that's
something else (I forget at the moment). In effect however, contrast
range specs for video projectors probably correlate to deeper blacks,
but that's not what 'contrast' means. Your formulation beloew is
grammatically equivalent to "strong stomach (cancer)."
Perhaps, when/if photochemical imaging recedes into the past the word
'contrast' will undergo a full meaning-shift, (going back to the
'contrast' knob on TVs, which doesn't actually adjust contrast)...
but not yet.
