i just bought a new macbook pro with 2,2ghz, 4gb ram, 15" matte lcd screen and a
250 gb samsung hd. what i found is this:
for some reason my lacie colormeter dont see the lcd monitor colors correct. it reads them by far to green and so the calibration results are with a magenta tint.
after many comparisions with my eizos i found out that
if i calibrate the screen with a 10m Magenta (lee) filter, the results are acceptable. Luminance has to be corrected about 20 for the light fall of through the filter, so adjusting the monitor with a setting of 60L and 7000K result in a final luminance of 80 and a final temp of 6300K with acceptable grey balance.
has anybody an idea why the lcd screen is not interpretated well by the lacie claibration tool,- the pb g4 can be adjusted very good with the same tool and program.
i was readng that mac uses two different monitor manufactors in the 15". i would like to know which montior i have in mine .... is there a way to find it out? maybe i have the "bad" one,- at least i really cant understand how people may like this new lcd screens very much.... the gammut is narrow ( way less than sRGB ) and by far not as good as the pb g4 monitor ( which reach nearly the full sRGB colors ) , the angle change very much the colors.
also i made a mistake to build in the 250gb drive. saving big files and ps ( cs3 ) becomes so slow.... i will change it again.
further the powerbok has some strange noise, very low level but very uncomfortable in a silent environment, similar as the first serial of the mb-pro last year. the noise has nothing to do with the fan, its a seperate noise,- i hate it.
at all i am disappointed by the new macbook.

Can I suggest you take a look at http://www.robgalbraith.com/bins/content_p...cid=7-8741-9027 (http://www.robgalbraith.com/bins/content_page.asp?cid=7-8741-9027)
He reviews the new LED screen and describes his calibration experiences in comparison with the older model. As for the display itself he describes it as 'Very, very good'
Worth a read imo.

yes i already have read it. no comments about that.... except that i cannot understand him and his
test. no idea how he can write that.

Galbraith suggests setting the White Luminance to 120 cd/m2, white point 6000K and gamma 2.2 prior to calibration.

and ? this does not change that the monitor is "seen with very different green-magenta spectrum.
maybe the calibration tools have to be updated for this lcd montors. or they behave so different from one to the next.

Maybe your colorimeter is faulty. Have you tried calibrating with a different device?

yes, with a spider2 also it results in strange colors. didnt had an eye-one here.

Colorimeters are notorious for being tuned to screen technology which is one reason the models appear and disappear so quickly. I think Huey might actually do well here because it's the most recent product...
I would expect a spectrophotometer -eg. EyeOne Pro- to be able to calibrate the screen.
Although the cost seems high at first, I would strongly suggest that anyone in professional photography who has several screens invest in an EyeOne Pro and amortize the investment over a few years - divide the investment by the number of screens you need to calibrate and it becomes tolerable. And you might even use it for print profiles
