    Picked up a 3.06 today for a buddy of mine. Still the same panel LM240WU2-SLB1, brighter on the left side, darker on the right. The color gradient is more even but it has horrible backlight bleed. 1 stuck pixel(red) far left center...

    I have the older imac intel 17 inch and even thou a couple of years old- I would get the smallest imac and then purchase a third party LCD like my NEC 20 inch. Being a photographer, I have to have the most consistent monitor to get the proper calibration-something you just don't get with an imac? It only has the one brightness control-which isa joke if you desire proper calibration.
    Apple just doesn't seem to get it; and they used to as this was there main market years ago. Now that they have gotten bigger, they seem to have forgotten the graphics market and just become another computer hardware maker. At least when it comes to imac's.
    I wish they understood that a lot of photographers don't want glossy imac's and preferred that matt for calibration; this is why it's better to have a tower computer-but again Apple doesn't seem to get it; BRING BACK THE TOWER MAC at a lower price than a mac pro!
    I suggest everyone start emailing Steve Jobs

    Geordie, based on your description, i have the exact same problem with my new 24" iMac. the cold blue on the right side of the screen is really terrible.

    what's i found interesting is that if you set your screen to a dark grey, and turn the brightness all the way down, you can actually see a wide vertical band in the middle of the screen that seems to represent the yellowing in the center. seems as if the screen is being pressured by the components in the back.

    apple's new iMac displays are flat out embarrassing... in their quest to make the computer as thin as possible they've clearly compromised quality for aesthetics... as if an additional half inch thickness would really matter to anyone... the iMac screen is trash... budget PCs have better screens!!!

    DarkroomMTL,

    I think you're onto something. It DOES seem that there is pressure against the LCD coming from all those components pressed into the thin shell. Even the slightest pressure on the back of my 24 inch Alum imac would create an effect on the front. Ok, I have seen many LCDs do that when you press from the front but never seen that from the back. I tried it with some of our Dells and LG external LCD's and didn't see this. Can someone else try this to confirm?

    I also found something interesting (perhaps others can try this too) with my personal 20 inch Alum iMac. When I would lower the brightness to about half way and turn the built in Airport on and off, it would affect the screen. There was flickering on the panel and the LCD lamps seemed as though they were trying to adjust. Weird.

    I have had mine for 4 days now so have 10 days left if I want to take it back to the Apple Store. It's a tough call as there is definitely a gradient on the screen but it's quite subtle. I know people will be thinking it's very expensive for a computer and at this price it should have a perfect screen but I'm wondering whether to send it back after reading how many times other people have had to do it before giving up.

    So my options are -

    - Live with it. I'm a graphic designer but this is a home machine - I have a full time job and don't do colour critical work at home too much.

    - Take it back and get a replacement, which I may have to do a dozen times before I find an acceptable model.

    - Take it back and invest in a Mac Pro or a Mac Mini (too expensive and too crap respectively).

    I don't suppose anyone has had any luck having them repaired? Does Apple recognise this as a repairable problem or is it a design flaw?

    Geordie,

    Personally, I am staying away from iMacs. Even if Apple can fix it, I cannot spend countless hours or days going back and forth to the Apple store until they put in the right LCD.

    I would get a Macbook Pro if you can afford it.

    Other than that, I don't want Apple forcing me to buy a Mac Pro just to get a good external LCD.

    I hope that Apple updates the Mac Mini with faster CPU and hard drive.

    I guess you can also buy a Macbook and and external display but then whats the point, I would just get a Mac Mini.

    I don't know. It's all so confusing!!!

    The Mac Mini is not a crap machine. Since they put the Core 2 Duo chips in it and raised it's ram capability it's a pretty good computer. It's pretty much identical to an iMac.

    It's draw backs are:
    A cheap video card which has low memory and must use the CPU for any graphics intensive jobs. This only matters with gaming or very high end graphics or video, would still work well with 2-D graphics.

    And no ability to add a second monitor.

    It has a 5400 rpm hard drive which slows things down a bit but not hugely.

    If you don't have your own monitor and keyboard to use then you have to go out and buy them, raising your price up to that of an iMac. But if you do have them it's very cost effective.

    But Apple definitely needs a Pro machine in between the Mac Pro and Mac Mini.

    Other alternatives are to find a white iMac, the last generation with a 2.16 GHz Core 2 Duo processor are very fast and have the high quality matte 8 bit screens. I'm working on one now and the screen is gorgeous and flawless. Or see if you can get a used Mac Pro, even a G5 would be a pretty fast machine and a lot cheaper than a new one.

    I do not have these screen issues. I just did some testing as someone mentioned a few posts earlier and my screen is even. I have the 2007 aluminium 24" iMac. I bought it in a local Apple store and took it home, half a year ago.
  • Kevin Horn Level 4 Level 4 (1,825 points)
    Komkommer: Consider yourself lucky, reading the posts here show that some people have taken it back several times and still not gotten a good one. I have read some posts where the gradient seems to go away after the iMac has been on for a week or so, as if the screen just needs to warm up and get broken in.

    Someone mentioned the screen being pressed from the back. I don't know if there is too much pressure on it, but I have to say I think it is something in the thinness of the new iMac design. In the beginning 6 months ago it seemed like the problem was only on the 20" model and many were saying it's just the nature of a cheap TN screen, but then reports came in about problems with the 24" display as well which is not a cheap TN film but is the better quality 8 bit screen. Also the 20" models all have the gradation from top to bottom while the 24" have the problem going side to side.

    And if you go out to the stores and look at various TN film monitors you will be hard pressed to find one with any gradation at all, this leads one to think it's the design of the iMac. The fact that the problem is different on the 24" is also an indicator of something wrong with the design.

    So I am thinking this isn't even a matter of Apple not caring about quality, I think there is a flaw in the nature of the aluminum iMacs that nobody anticipated. The problem isn't always easy to see, either, so it's possible no one at Apple noticed it before the iMacs hit the stores, too late to recall them at that point.

    The fact that the problem still exists in the second release of the iMacs says they haven't figured out how to fix it yet but they have schedules they have to keep and their sales are through the roof so obviously it doesn't matter to the consumer anyway. Reviewers fail to mention the problem because they depend on Apple for their stories and don't want to **** them off.

    Could you please check which display is used?

    In terminal.app:
    ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6

    Is that white 2.16 iMac really free from problems?
    Some white iMacs were noisy AFAIR...?
  • Komkommer Level 1 Level 1 (30 points)
    Come again??


    +Here's a quick-n-dirty way to determine which LCD panel you have (without downloading+
    +SwitchResX). Cut-n-paste the following command line into Terminal.app:+

    +ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6+

    +Disclaimer: Works on Leopard, but I don't know whether it requires the Xcode tools.+

    +...in the beginning was the command line,+

    Looby
  • Komkommer Level 1 Level 1 (30 points)
    You gave me the wrong command. This weird website won't display square brackets for some reason

    Anyway, here is my display:

    LM240WU2-SLB1
    Color LCD

    What does it tell you? It means jibberish to me
