So what's the black level luminance on the Eizo? If you operate the Artisan
at near the recommended 80 to 85 Cd/m2 (I'm citing the documentation from
memory), in order to achieve a 500:1 contrast ratio you need the black
luminance to be around 0.17 to 0.16 Cd/m2. In comparison (I was going to say
'in contrast' -- no pun intended), let's assume you drive the Eizo at the
recommended 120 Cd/m2 white luminance level, I take then from your verbal
accounts that the Eizo can't physically give a black luminance of 0.24
Cd/m2? Which would give a contrast ratio of 500:1. So what kind of contrast
ratio are you seeing: more like less than 300:1 or (worse) 200:1?
The EIZO does an honest 400:1 at 120cd/m2, with a black level of
something close to 0.3 cd/m2. (The only instrument I own that I trust
to take accurate black measurements that low is the Artisan puck, and
I don't have any software that would let me use it to measure the
EIZO black. This is one of those times I find myself wishing for a
Minolta CA-100.) Visually, the EIZO looks very close to the 0.3 cd/m2
I get on the LaCie CRT with their calibrator.
At 200 cd/m2, the contrast ratio seems to deteriorate-black looks to
be about 1.5 cd/m2. But it's an excellent monitor. I'm not trying to
denigrate it in any way. I just found Derrick's claim about the
blacks compared to the Artisan in direct contrast (no pun intented)
to my experience.
