Mmmm... so some of the yellow colour cast some people talked about might just be colour profile and not the hardware as some have speculated earlier...

Just another word on icc... if you do try this icc, do install it leave it on the screen for a bit, it is amazing how our eyes can get use to almost anything so chances are your eyes are use to your screen looking blue-ish. Give your eyes a chance to get use to it. Then, after while, you can try changing it back to default icc and you will see the difference.
 
Am I the only one who thinks the OP's profile is too red? It's great, but it's too red for me :(

Mmmmm.... this could be one of two things... either you got use to your screen being blue-ish and now that it is corrected, it might appear red-ish. OR the profile is not working for you. As I said in the previous post, give it a go. I would suggest changing the profile JUST before you have to go out. Then, hopefully when you get back, you forgot you changed it. Later on, if you remember that you changed the profile, try changing it back to default icc and you might notice that it is too blue-ish.

As far as the profile goes... it is done by GretagMacBeth Eye-One 2 so it is totally non-subjective. A few people have tried it and seem to like it better than default so might be worth a decent go. If you have really tried it and gave it a fair go, you may have found that it can not work on all LED MacBook Pros.
 
Samsung vs. LG

The reason it's too red for you is because you are using the LG profile on a Samsung screen. The LGs have a cyan(blue)/green shift while the Samsungs have a magenta(red)/yellow shift. Thus using a profile that is shifterd towards red on a screen that is already biased towards red will make it even more red. ;)

Can anyone post a calibration for the samsung screen? Thanks for your work so far on this profile; however, I want to see if the profile tested with samsung will be of further help to my screen.

I also wonder if anyone out there with a samsung panel could do a professional calibration. :cool: (pref /w a glossy screen, though I dont know how much a difference that would make)
 
Great profile! Do you have any idea how to apply it in VISTA so that my occasional windows forays can look as good as your profile does in OSX?:confused:
 
This is my profile for a 9C68 glossy 2.4 GHz. Profiled with a Colorvision Spyder 2 Pro

I downloaded your colour profile the other day, thanks for that, it's a LOT better than the default yellowish one. I've got a Samsung matte screen though, so it does look a little too pinkish to me.

Does anyone else happen to have a colour profile they'd care to share? Thanks :)
 
Great profile... it definitely rocks for the LG screen! I have no doubt that I'm not suffering from the dreaded "yellow screen".:D
 
New Penryn Macbook Pro 15 LED - saved by this profile

Hello I just took delivery of a new Macbook Pro 15" w/ LED backlighting and glossy screen and was very disappointed with the color cast of the screen. I was almost ready to return the machine. It looked washed out and too green, the saturation also seemed too low. This I noticed as soon as I turned on the bloody thing. Shame on you Apple, not sure what gives with the out of box color on this laptop but I expected better from Apple. In any case I tried the profile submitted by the original poster and it did the trick. Now the machine looks like it should. Thank you so much.
 
Actual calibration data for Glossy screen using EyeOne

As you can see, the profile makes such a big difference in image quality. It may occasionally work to use someone else's profile (as in this case), but there are always variations in hardware performance, so to really make your screen all it can be you need to buy a colorimeter probe and calibrate your own system. I have run some tests lately using the EyeOne LT and I am very pleased with it's performance. I have also finaly convinced myself that the glossy screens on the MBP and MBA are actually better that the matte in terms of color accuracy and saturation.

Please see this thread where I have recently posted my calibration results. The calibration was done using EyeOne Match, but the measurements before and after were made using HCFR SW.

I have two questions;
1) How do you know the color is accurate? What criterion do you use?
2) After calibrating the system, could the color gradation be smooth?

Glad to hear matte displays are benefiting as well.

Hi-there, you seem like just the guy to ask this question I've had for a while, a question I can't seem to get an answer to:

I am trying to do my own color calibrations with the Display Calibrator Assistant (for my Pioneer Kuro Plasma). But I'm having some problem with the instructions.

There is one instruction that repeats itself over and over again: "Move the right slider until the shape is neutral compared to its background." I'm not sure what this means. Shape? -- as in the line on the very edge of the apple disappears? Am I concerned with color at all at this stage?

What exactly am I trying to do here? I don't get it. Can you verbalize it for me?
 
Hello,

Last week I purchased my very first Mac – the 15-inch : 2.4GHz base model.

Unfortunately, I was unlucky in that I received one of the computers with the notorious yellow-on-the-bottom-1/3-of-the-screen problem.

I elected to go with the glossy display and received the display model 9C83 (not sure who the manufacturer of the aforementioned display is).

My question is; is there a color profile (specifically for my model screen) that may correct this yellow screen issue? I have heard that if one finds a more appropriate color profile for their screen model, then they can correct this yellow issue? Is this true?

Does anyone have a great color profile for the screen model 9C83?

Thank you very much in advance.

As far as accurate do you mean in hue or brightness? Every visible color is describes by a set of three numbers. It could be RGB or xyY as in the plots I uploaded. The exact color of the primaries Red, Green, and Blue are precisely defined by standards bodies. Basically, there is only one real "Red", etc, for the colorspace you are using. The CIE diagram I showed shows the ideal points for the primaries along with what the monitor is using to try to provide these colors. The closer they are the better.

In addition to this, the calibration runs a series of 11 grayscale patches on the screen. This is a special "gray". It is comprices of exactly the right proportions of red, green, and blue to achieve the desired color temp (usually 6500K). The calibration probe measures the actual components present in the gray patch and compare to the proportions they should have. It repeats this over the full range of brightness (11 steps from 0%, 10%, ... 100%). If the grayscale is not correct all colors will be off. In the case of the mac, the calibration SW automatically creates a color profile to attempt to make the colors match the standard values for the primaries and the grayscale, but in order to do this you have to have a probe to put on the screen.

There are also saturation measurements. For example, the color standard for HDTV says that for any given brightness, the value of pure red should be 21% of the value of pure white. There are similar numbers for green and blue. If you crank up color saturation these will be higher.


If you are serious about learning how/why calibration works I recommend the following link as a start.

I would really like a color profile for the 9C80 LED display. Mine is to yellowish :(
