Very recent HD monitors are claiming 400:1 brightness ratio. That's
just a
nudge more than 13 stops. Pretty amazing stuff if true.


400:1 would be just under 9 stops, did you mean 4000:1, which would be
just under 12 stops?

(Brainfart. 13 stops would need almost 8192:1. Should be able to get a
toasty tan from across the room. For you bit jockeys, the brightness range
of n f/stops is simply 2^n.)

Many LCD monitors are rated at 200:1, or less than 8 stops. Funny that I
never stopped to think about it that way. My monitor is a good match for
carefully printed and processed B&W silver gelatins.
