If I recall correctly, I think there were some tests going on
between several of the frequently-mentioned LCDs on this list. Any
final or preliminary results to post?
We are still evaluating the test results, but the preliminary report
goes like this. We tested the following LCD monitors:
Apple Cinema Display 23"
Apple Cinema Display 20"
Formac TFT
Eizo L985 EX
Eizo L685 EX
Nec LCD1920NX
Sony SDM-X82
Sony SDM-X202
Mitsubishi E85 LCD
We asked the distributors which LCD monitor they would suggest for a
photographer. These were what they sent us. We also got a monitor
from Samsung, but it's software didn't work on the Macs that we used.
These monitors were used on a Mac G4 with a ATI Radeon card, running
OSX 10.2.3, trying to use the DVI cable if possible. We calibrated
them with a EyeOne calibrator with the Basiccolor Display. The
evaluation was made by comparing the MacBeth card, placed in a Just
Lightbox, with the MacBeth image, which can be downloaded from Bruce
Lindbloom's site. We adjusted the brightness on the lightbox to make
the white patches match.
We've also displayed some images that we know well and a stepped grey
scale, together with some grey and color ramps. The monitors
different color spaces were compared in Color Think.
We think that the two Eizo monitors gave the best results, closely
followed by the Apple monitor. The Eizo monitors have many different
settings, which made it possible to adjust the monitors before
profiling them.
It was surprising to see how easy it was to get the Apple monitors to
match the target. Normally you expect that if you have more controls
and settings on the monitor, it would be easier to get a good match.
Here we just set the luminance to maximum, tried some different gamma
settings and decided to use a gamma of 2.2 and adjusted the white
point setting so we got a match of the white areas of the card. Then
we just calibrated the monitor and got a very good a result. For
those that don't want to fiddle with the controls, the Apple monitor
is a good choice. But all the different settings on the Eizo monitors
made it possible to get even better results.
As we were able to get a luminance on these monitors at around 200
cd/m2, it's easier to have a good match between these monitors and
the image in the lightbox than the CRT monitors that we used before.
Really don't like the results when I turn down the lightbox all the
way down to the low brightness levels I have to use if I'm going to
match CRT to lightbox.
