Unfortunately, these are probably due to slight variances between our respective panels. Here are some other suggestions to try:

1. At a bare minimum, calibrate in non-expert mode and choose 2.2 Television Gamma. This method won't alter the default colors but it will reduce the brightness of mid-tones a bit.

2. Calibrate in expert mode and really take your time to align all the sliders. It's fairly tedious, but I've achieved good results this way.

3. Give SuperCal a try.

THANK YOU so much for the link to SuperCal. I've never heard of it before and I wasn't satisfied by the other posted profiles. SuperCal did the job!

I'm 200% happier with my display now. Thanks to you!
 
Can someone post an calibration file for 24" ?
It's also a lot too shiny, stupid gamma correction on this models...
 
Can someone post their SuperCal calibrations.
Here is mine. After making several of them, this is the best one of the bunch. It looks great on my 20" monitor, but it may not work for others. Might as well give it a try.

Anyone got a good profile for the 00009C6B display? (Is one any better than the other?)
 
Loving SuperCal. I didn't realise how bad my new iMac 20" screen was until I started reading on here, but this has cured it. (Yes there's still a *slight* wash-out towards the bottom of the screen in iTunes, a characteristic of the particular LCD type, but nowhere near as bad as it was). I'm actually liking Leopard's new colours a lot more now that they're represented correctly instead of the glaring white-on-white-on-white I had before.

Funny, the Leopard default backdrop isn't as detailed towards the bottom once the correct calibration is applied. Dark purples turn to black, and the smaller stars disappear. It's difficult to know what's "correct" but everything else looks so much better... my photos, the interface, and even the new Leopard icons. Dock icons don't look washed out any more. Heck even the so called "fuzzy blob" for active apps in the new dock is actually acceptable now.

It doesn't look as extremely bright and radiant as it came (turned the brightness control down 5 notches too), and perhaps this explains Apple's reasoning - when you first see one and see the blinding screen you just think "wow" and it bowls you over (and hopefully tempts you to buy one). That's the effect Apple always go for these days. Once you're starting to get settled though, the desire is for accuracy, and SuperCal delivers it.

I'd probably switch to the 2.2 gamma built-in "easy mode" calibration for when more detail is needed in dark areas, but overall the profile I created in SuperCal (with the "typical PC" gamma of around 2.5) is a great all-rounder. Another side effect was a drastic "thinning out" of fonts towards the bottom of the page when reading forums such as this one, which is now gone. Yay.

I realise this isn't a "cure" for what is basically a lower spec LCD than others. But the lower spec is not such a glaring issue as it was before, because it's no longer being magnified tenfold by very poor factory-preset calibration settings. Perhaps this will be looked at when they start pre-loading Leopard onto the new iMacs.

I'd post my profile, but I strongly recommend downloading the SuperCal app and doing it for yourself because everyone has a different screen, eyes, preferences, brightness setting, viewing angle, ambient lighting... (the list goes on).

Edit: Greys do seem the most heavily affected. The active window titlebar for example is quite dark (like brushed metal) at the top of the screen, and lighter (like old Unified) at the bottom. For me personally, this isn't enough of an issue to make a fuss over... if I wanted perfection I'd research it and buy it (TBH it probably wouldn't be Apple)
 
Where do you guys check for display model #s?

Thanks a bunch! I just found this thread and I finally know why I have trouble reading text with this iMac. I thought it was my eyes but once I calibrated using 2.2 gamma, it seems perfect to me. However, I'll give SuperCal a try.

FWIW I ran with a gamma of 2.2 for a few days and the Mac UI just seemed too dark and dismal so I changed it back to 1.8 (but calibrated). Calibrated 1.8 is waaaay better than the factory 1.8 which looked all washed out and yellowy and yuk.
 
Just to put in my 2¢.

I am currently using the "perfect" calibration setting given above. So far, after all these months of experimenting I like that one the best (including ones I tried to create myself).

I also am running a gamma of around 2. Not 1.8 and not 2.2, but somewhere in the middle.

I also just discovered an app called DarkAdapted X, which gives one much better control of ones iMac brightness levels. I also noticed with this program darkadapted, that when bringing down the brightness level on my iMac (when using it at night) the levels look qualitatively different and better than when controlling brightness with the F1/F2 keys. I implore anyone out there to experiment with this free program and post their comments. I am surprised I have never heard of this program until about a week ago.
 
daneoni, did you ever find a suitable calibration? I just got my 20" imac and it has the same 9C6A monitor
 
Attached is a ColorSync profile for the new 20" iMac. It was created with an i1 Display 2 hardware calibrator. The target was medium white (6500K) at gamma 2.2. It should be suitable for most purposes.

To use, unzip the attachment and place the resulting .icc file in /Library/ColorSync/Profiles. You should then have an "iMac-i1" entry on the Color tab of your Display preferences.

NOTE: Because all displays are slightly different, this profile may not be completely accurate on your system. It should get rid of the washed-out look of the factory profile, but you might notice a slight color cast if your display is much different from mine.

I put the un-zip ICC file in the folder stated above, but when i go to the color tab of the display preferences i don't see "iMac-i1" :(.

I have a new 20" iMac with leopard...

anyone?

pax,
rudy
 
:( I have it both my home directory and in the HD's home directory (a custom one i made appears here) but the one i downloaded does not appear in the "System Preferences" -> "Displays" menu :(

Man, i'm the only guy this has happen too?!

No unfortunately. I tried several other calibrations but found the "Perfect" one to be the best of all of them. Hence i've settled with that one
 
I just did an alternate version to the Perfect.icc one i created a while back. This one has less gamma and is easier on the eyes...well my eyes...some might find it a little too dark. Basically YMMV.

Enjoy

PS. My screen is a 9C6A, therefore the profile may not be compatible with some other displays such as the 9C6Bs

Hello,

The calibration of 20'' iMac increase the life expectancy of a LCD display? Or te purpose is just improve the colours?

Thank you.
 
What LCD do I have? it lists my video card and then for Device ID it read 0x94c8

I have tried calibrating with the advanced mac options and Supercal.

My colors always look messed up still. They are just not set right.
 
Doesn´t matter the kind of calibration of the display, the chances to get dead/stuck pixels in the iMac's display are the same, right?

That's it?
