Uneven lit Display on 24" iMac

I am disappointed that my 6 month old iMac display is very unevenly lit. The left third part of the display is much lighter. There also seems to be a little color shift in the lighter part. I am a commercial photographer and this display is next to useless this way. Anyone had the same problem?
Thanks, Gerhard

If your iMac is only 6 months old you do not have a G5 iMac (which this forum is about) but an Intel iMac, the forum for which is here:

  • How do i set up a second display for my iMac desktop?  I want to use both displays at the same time.

    how do i set up a second display for my iMac desktop?  I want to use both displays at the same time.  My iMac is the 24" Late 2006 model.  I recall that there is a cord for plugging in a second monitor, but I want to make sure that i can use both monitors side-by-side at the same time.  thank you.

    If the Display supports DVI, then you will need a > Mini-DVI to DVI Adapter and a DVI cable.
    If the Display only supports VGA, then you wiil need a > Mini DVI to VGA Adapter and a VGA cable.
    Noting that the (digital) DVI is far better than the (analog) VGA connection.

  • Problem with LCD display on 17" iMac G4

    The LCD display on my iMac went wacky on me yesterday. It's as though one of the three primary colors no longer works. The screen has a green tinge to it, and anything that's supposed to be black shows up as green. I've reset everything, run the Hardware Tools diagnostics (no problems found), and changed resloutions, monitor depth, and brightness levels many times. No luck. The screen is readable although very ugly.
    Obviously I can take it to an Apple Store, but does anyone have any idea what it might be? I've searched the net and the forums and can't find anything close, but I know I can't be the only one to experience this problem. I called a mac repair shop a few minutes ago, and they said that the logic board would need to be replaced. I just can't believe that because nothing else is a problem.
    Please help. Thanks.
    17" iMac G4 1Ghz   Mac OS X (10.4.6)  

    I "fixed" the problem a few days ago. Digging around here in the forums, I found another thread that gave explicit instructions on how to open the iMac and re-seat the connections. Here is the link (http://discussions.apple.com/thread.jspa?threadID=196785&start=30&tstart=30). It's a post from Androcles made on 3/26/06.
    Just as he indicates, when I did this I found nothing to be loose at all, however upon putting it all back together, on the 2nd re-boot all was back to normal and still is. It's amazing how clear and crisp the screen is after suffering through the green hue for a few weeks...
    Good luck, and feel free to ask me for help if necessary.

    Hi there,
    The simplest way is to drag it across wirelessly using the 'Airdrop' application once both computers are near one another. 'Airdrop' can be found near the top, on the left hand side menu, within 'Finder'.

  • How do I get Windows 7 to display in Target Display Mode on IMac

    I am increasingly frustrated by my inbability to get my Mac Mini running Windows 7 to display on my late 2013 27" IMac using Target Display mode.
    My setup:
    1.  IMac 27" Late 2013 running OSX 10.9.2 with all the latest drivers as of Mar 7, 2014.
    2.  Mac Mini Server Mid 2011 running Windows 7 SP1, 64bit, all the latest Windows drivers as of 3/7/14, using the latest BootCamp Drivers for this machine, ver 5.1 downloaded 3/5/14 to this machine using Boot Camp utilities in its OSX mode.
    3.  Connected via Apple Thunderbolt cable.
    My process is as follows:
    a. Turn on the IMac, boot up in the  normal manner, preparing it to run in Target Disk Mode in OSX.
    b.  Turn on the MacMini boot up via BootCamp,  in the normal manner in to Windows 7.
    c.  When Both machines are on and connected via their Thunderbolt ports, I enter cmd-F2 on the IMac keyboard to enter Target Disk Mode.
    Nothing happens.
    I use this IMac to display my MacBook Pro in OSX, so I know it is working, but I can't see where the problem is.
    I have reviewed all of the Apple support information and followed it explicitly, to no avail.
    When I have called the Apple support team, I get little help, they assert that they can't troubleshoot because it is not all Apple hardware/software (everything including the Thunderbolt cable is Apple except for the Windows OS)
    Any suggestions will be welcome...
    Thanks!

    I have finally achieved some clarity on how Target Display Mode works, or rather doesn't work.
    And I have been mistaken in some of my prior comments.
    Target Display Mode is a function of the host machine, at this point only the IMacs.  And it is only available when the host machine is running OSX.
    But the most recent Thunderbolt versions of the IMac have been significantly dumbed down in this functionality.
    The prior generation of IMacs whose video was supported through the Mini Display Port supported almost any input from a Mini Display Port compliant Computer through the use of various mechanical adapters, and certainly from any Mac Hardware or software combination.  It was a very versatile setup, and the IMac in this manner could serve as an absoloutely beautiful monitor for a wide variety of hardware/software combinations.
    When the current version of the IMac was deployed using the Thunderbolt ports for input for external video, we apparently left a world of standards based video input and entered the world of Apple proprietary video. 
    The current model of IMacs with thunderbolt video have a very limited functionality in Target Display Mode compared to those of us who have used it previously. and it only functions when the client machine is running OSX. 
    No other video input from any source will display. 
    I am not quite clear on the reasons one would want to display OSX on an OSX native machine, but you can do it.  I guess MacBook Pro or Air running OSX will now display on the IMac if that is your need.
    Likely the most likely need for Target Display Mode for the rest of us is to run Windows on an external machine and display the video on the IMac, as we have been able to do with the prior generations of IMacs for several years now.
    Apple has been unwilling to distribute the technical specifications of its video input requirements in Target Display Mode, (other than to assert it requires OSX), and these technical specifications appear to be proprietary. 
    I have personally unsuccessfully  tried to  display the output from both Windows 7 and a Windows 8 machines running from a Windows thunderbolt port into  a thunderbolt port on a current model IMac using Target Display Mode.
    Unfortunately, there are still a few applications that won't work in Mac world and require a native Windows machine.  My current need is to run Dragon Naturally Speaking via Citrix to a remote Citrix server and a Windows app.  Parallels and VMWare Fusion do not work, nor does the OSX version of Dragon Dictate function via Citrix.  So I am stuck.
    I hope that Apple, so long a leader in technology, will restore the functionality it abandoned when it embraced thunderbolt as its only video iniput in Target Display Mode.
    Thanks!

  • 2nd display for my iMac - Recommendations?

    Hi,
    I have a 24 inches 2009 iMac.
    I would like to add a second display. Nothing too big - something like 19-20 inches.
    Any recommendation? brands, model?
    Any brands come with the mini display connector?
    What are the characteristics I should be looking for the ensure I get acceptable performance (let say similar to the display of my iMac) and good integration with the Mac?
    Thanks

    In many shops you can filter on specs.
    Exclude screens with TN panels
    Include screens with DisplayPort (DVI or HDMI is possible too, but the adapters are more expensive)
    Set size to maximum 22" (most displays are 21-22 inch nowadays, 19 inch ones are DODO's).
    Things you will find are:
    HP ZR22W
    Dell Ultrasharp U2212HM

  • Using a macbook pro as a second display for an imac using a thunderbolt to thunderbolt cable

    I know I can use TDM to use an imac as a second display for a MBP with a thunderbolt to thunderbolt cable.  Is there any work around to use a MBP as a second display for an imac with a thunderbolt to thunderbolt cable?
    15" MBP w/retina running maverick 10.9.4
    21" imac running maverick 10.9.4

    No; the MacBook Pro doesn't support video in. If desired, use a product such as ScreenRecycler over a network.

  • Using an iMac as a 2nd display for another iMac?

    Hi all,
    is it possible to use an iMac as a 2nd display for another iMac?
    I guess it depends (if at all possible) on the models, right?
    Would it be possible with two of the currently available iMac 27" models?
    Is it just connecting the two video jacks with a cable? That would mean that the jack is input AND output connector at the same time: the video signal would be output from iMac 1 and serve as input for iMac 2.
    Thoughts?
    Thanks,
    Stefan.

    Awesome, David! Thank you! That helped a lot!
    Additional question: because running applications on the target-display-mode-iMac keep running: will I be able to connect from the source iMac to the target-mode-iMac via OS X's Share Screen functionality? So that I can still USE the 2nd (target-display-mode) iMac for running applications and accessing them? Or is the iMac in target display mode really just a dumb display? Will ssh'ing to it work?
    A little background: programs like Cubase and Logic work really great with two screens. Additionally, some audio plugins really need a lot of CPU power and some of those can actually distribute the number crunching via the LAN to other computers. So my thought is: run Cubase on iMac #1, use iMac #2 as a 2nd screen (will work, thanks to David's reply) AND use iMac #2's CPU, too, to help some Cubase plugins' number crunching. Would that work?
    Thanks a lot,
    Stefan.

  • I want to use TV as a display on my iMac 2009.

    I want to use TV as a display on my iMac 2009.
    Is it possible?

    There are two possibilities for high resolution with the new iMac;
    The Apple or 3rd party mini-DisplayPort to DVI-D single-link adapter has a maximum supported resolution of 1920 x 1200. Use a DVI-D single-link to HDMI cable if you have HDMI ports on your TV.
    The Apple or 3rd party mini-DisplayPort to DVI-D dual-link adapter has a maximum supported resolution of 2560 x 1600. Use a DVI-D dual-link to HDMI cable if you have HDMI ports on your TV.
    The better cabling that you purchase the more bandwidth available for transmission and the less digital artifacts in your images. More expensive is not always better quality.

  • Connect 2 external Displays with a iMac 27''

    Hi,
    is there a way to connect two external Displays with a iMac 27inch. Eyefinity? Its a Radeon 5750 inside the iMac isnt it?

    Hi,
    For the first screen is no brainer you use the Apple adapter to have video out to HDMI or DVI, but the second screen is where it gets tricky...
    There are USB to DVI out external video cards that should work with the iMac and OS X 10.6 but I have changed. Honestly I have tested 6 so far and none of them works as advertised, you can not even set minimal resolution on there and some wont even work ( all of them come with OS X 10.6 drivers )
    So I will recommend to stay away from the small $70 or $90 external USB to VGA/DVI cards...
    (maybe someone has luck with them but i have tried like I said 6 so far different brand and no luck..)
    Now recently online I tripped over a nice external video card that takes the MiniVideo Port out from the Mac and then takes it to another 2 monitors price was $249 i think, and you could hook up 2x30" monitors with hight res... I will try to find this link and post here later on.

  • Switching displays with broken iMac display

    I have no display on the iMac. I want to back up the hard drive before it is sent for repair. So I need to use external display to do so.
    Using mini DVI to VGA adapter to connect iMac to Sony Bravia 40", but the TV will not pick up the signal (Probably due to incompatible resolution settings??).
    Is there a way to switch the display settings without using monitor display to see what I'm doing?
    Maybe I could do it with speakable commands which luckily is enabled on the computer!?
    I was able to open system preferences and then display preferences (I think).
    I've searched high and low now for an answer, but have come up with nothing.

  • IMac display in newer iMacs

    Hi all.
    I'm thinkin in buying a new iMac to my father. Will he be able to use the display that comes with the iMac when he wants to change AGAIN his computer?.
    Same question, diferent way. Can I use the display on an iMac as a display for other computers (i.e coming iMacs in 2010, 2011 etc!:).
    thanks for your help.

    hey, thanks for the superfast answer...
    It's a pitty you cant use the display if changing the computer. Most computer will be obsolete in 3-4 or 5-6 for home use. But the display can live a lot more.
    Is it so difficult to add an input port?.
    this is a retoric question!, don't need to answer...
    I just think it would be better to buy a mac mini and a separate display. What do you think?. The most processor-demanding task or graphic card-demanding task my father would do is google earth and some basic photo editing.
    thanks again

  • PS is too wide (large) to display on my iMac

    I don't know what I've done, but both my my lightroom  and PS CS4 are now too large to display on my iMac.  Both vertically and horizontally.  I've been using them for a couple of years and never had this problem?  Any ideas on how to fix this?  I hate having to move the cursor to each side of the screen to see the panels in Lightroom and the same in Photoshop. 

    You accidentally resize the frames to large. Increase the resolution of the screen just temporarily so you can see the bottom right corner of the frames then reszie them smaller and that will hold when you relaunch.
    If you can somehow drag the frames until you see the lower right corner then you do not have to change the resolution of the screen just drag that corner toward the center of the screen until you are happy with the size of the frame.
    I sometimes make it bigger so I do not accidentally adjust some thing I dod not want to adjust. Probably not necessary but I do it any way.
