    In case anyone needs it, I put one together below:

    Compare the left and right sides and let us honestly know how yours did. And here's how my screen did and am not sure how this compares:

    Thanks.

    argh. not so good... my screen is worse than i thought.

    white -- blue -- grey

    but i'm only doing music production stuff so i might just suck it up unless apple publicly acknowledges that this is a problem that EVERYONE has and they're going to give us all going spanking new computers with beautiful, even toned screens, and free RAM and pre-bundled software to make up for it. :rolleyes:

    From what I hear, it is a problem for most.

    Anyone else want to share their results? How does yours look?

    Worse than the one above. Much more of a dirty gray on the right.

    I noticed my gradient when I put the apple site up twice (side by side) to show off the size of my screen. I immediately noticed the gradient. When I brought it back to the apple store, I showed them "my test", and they gave me a new iMac which was opened and tested on the genius bar. :)

    And how is yours now? Did you give it the test? :-D

    I wish they would do that kind of testing for me at compusa. They just get you in and get you out :-(

    Do not follow others and go looking for stuff, for if you do you sure wont like what you find.

    That goes for most things in life I'm afraid.

    Sad to say that if people/companies use the cheaper end panels then you will find all the issues that these cheaper panels have.

    Take a look at this page.

    http://www.codinghorror.com/blog/archives/000991.html

    The other thing is that if Apple had released the Imacs with a far far better Display Profile, then most people would not have even noticed the issues that these panels have.

    I also feel that if people who want these machines for professional photographic use are just buying without going to a store to see them first, then hey what can I say ?

    You didn't say, but I assume that the new one is OK?
    Since I haven't bought one yet, I'm trying to get a sense of where we are with this issue on recently purchased iMacs.

    According to that chart the "IPS" is the quality panel and that's what the 24" Al iMac uses. My old 24 Al iMac" and some other 24" Al iMacs seem to be suffering from this gradient problem mentioned above.

    Yesterday, I received my new iMac (20" 2.4ghz) from shanghai bought from the apple store.

    It is a week 47 (W8474****....) pre-installed Leopard. The gradient issue on it was massive - the dock looked horrible and washed out. Luckily (?) after I had a first play on it and familiarised myself with Leopard (that I have decided I didn't like) I turned it off and it wouldn't turn back on.

    Phoned up Apple and they've issued a refund. So today, I went to a local Apple store and purchased another iMac, an older one as it happens - a week 41 (W8741****....) and the gradient issue on it almost unnoticeable on it. The Dock is very colourful and it is a lovely screen. The best part is it is a Tiger machine.

    Very happy that three issues were resolved in one go... now let's try and explain to the credit card people about the 2K hit it has just had!!!!!

    I will post pics of the new iMac screen test in a mo, sadly the old one won't even turn on, so no comparison. Oh well.

    Here are the pics - set at full screen brightness. No flash on camera, 5.1 MP.

    The one I have right now is better than my first unit.
    However, there is still a yellowish tint I am not prepared to live with.
    On top of that the dvd drive on my replacement is a rather noisy optiarc drive while the first one was a very silent matshita drive. Right now, I am not happy. Not beeing able to get a proper white on the screen kills me. It´s the most frequent background in pdfs, web pages and what not.
    However, there is no guarantee whatsoever that the next replacement will be any better. I am kind of out of options.

    I'm wondering what brightness level people have their monitors at. I have mine all the way down because I find the screen extremely bright otherwise (and am guessing this also helps with power consumption?) but I feel like maybe it makes the gradient more noticeable.

    Thoughts?

    I'm still waiting for you to provide your hard data on this. Where are all those articles you mentioned??

    Why don't you get your Mini already and stop with the incessant whining about gradients in 12 different threads? If you think the iMac is such a universally flawed product what's the point, right??

    Gradient-free 24" aluminum iMacs are NOT rare. Please do not drink the Kool-Aid. If gradient problems were as widespread as this guy would have you believe there would be a public outcry so loud that Apple would be forced to comment on it officially like they did with the freezing problems, believe me.

    I'm NOT saying gradient problems don't exist in some screens but it certainly is as widespread as some in here would have you believe.

    Some people love to complain.

    Listen, I'm not going to waste my time on you or get into some forum pissing-contest, but lighten up and stop following my every move.

    The hard data I was referring to was the Tom's article. There was one more I had open on my work computer if you'd like to wait until monday to get it to do. Would that make you happy, sweetie?

    I just noticed that if you tilt the screen upwards a little, the gradient is less noticeable (before it was pretty much perpendicular to the desk).

    Sure, rare in on-line forums where people generally go with issues.

    Yeah, I agree. Which is why I'm still on the fence. However, I have yet to see one in person that was perfect, but everyone's idea of it varies.

    good luck. it´s probably not going to happen.
    I have had a total of three 24in machines shipped to me via apple bto and all of them suffered from the gradient / tint issue. two machines were complete rubbish - absolutely laughable, with the right side of the screen not beeing able to display any white whatsoever. I have a review of the AL Imacs by
    c´t magazin ( http://www.heise-security.co.uk/ )and they clearly spell out the issue. the review is in German (that´s where I live) but you can rut it through babelfish to get the picture. Good screens are a rarity with the Al Imacs. If you absolutely need OS X wait and see what Apple does with the Pros and ACDs.
