27" iMac split screen problem?

I went through the other threads but did not see a similar issue to this. I've had my iMac for a couple of weeks now with no problem. Today I was using it and this thick red/purple vertical stripe appeared all the way down the monitor, seemingly distorting my background image. After a few minutes the red bar went away but my screen now looks like a split screen with the left side being slightly darker than the right. The split screen only impacts the coloring, the Icons and everything still show up in the correct place. Has this issue been seen by anyone else?

Check MacRumors there was a picture of an IMac with similar issues there.

  • What is the technical 'cause' of the infamous iMac black screen problem?

    Can anybody shed some light on what technical malfunction exactly causes the infamous iMac black screen problem? The common solution seems to be a logic board replacement. But what exactly is broken on the logic board? Is it the Geforce chip? Some kind of external driver circuitry? Or something completely different?

    I was referring to the many problems also described in this thread (and also in many other places):
    http://discussions.apple.com/thread.jspa?threadID=196774&tstart=0
    In specific I am referring to machines where all of this applies:
    - internal monitor stays black after power-on
    - computer boots normally
    - external display works normally
    - internal display backlight works and can be adjusted in brightness, but all pixels are black
    - PRAM reset doesn't help
    - NVRAM reset doesn't help
    - PMU reset doesn't help
    - reinstalling OS / booting from CD doesn't help
    - machines with this problem sent to repair come back with a replaced logic board
    I'm looking for more information on the technical cause of the exact problem as stated above. So I can attempt to repair my iMac

  • Flash Player 10.2 - Fix for split screen problem on Youtube

    Just to let users and support staff know, I have had this problem on two separate Windows XP systems now. The problem also manifests itself on other websites (e.g. Liveleak.com, Dailymotion.com) and is also experiencing crashes. These are reported by me in the vague hope it might make a difference to the product's quality.
    I have solved it by Right-Mouse Clicking on the offending split-screen flash video and going to Settings, Display. Once there I have disabled the Hardware Acceleration feature and hey presto, all is working again.
    When Adobe issue a fix, I'll turn it back on again.
       Regards to all.

    Hi, Thanks for the feedback. Yes that does help in many cases. Sometimes updating the device drivers also.
    The hardware acceleration sometimes can't be used by every system. You can read about the system requirements and what and how it works here:

  • IMac - Triple screening problem.

    So I have an iMac 27" bought it about 6 months ago. Now I set Windows up on it via bootcamp and can succesfully run two monitors off it, one each side. However when I switch to Mac OSX it only picks up one of the two extra monitors.. I've tried various things but can't find anything to work!
    Thanks in advance!

  • Imac's screen turn into blue screen

    I bought my iMac @ July 2008, the imac running just fine.....but some how since last month, my mac will suddenly turn into blue screen for couple seconds then turn it back to normal ....
    I tried to format the iMac , Blue screen problem still access .....
    Can some one tell me what should I do to fix this problem ???

    HI Brian and Welcome to Apple Discussions ...
    You tried to reformat the iMac without success? Did you boot from the restore disk and verify the disk for errors first? If not...
    Restart your Mac while holding down the C key, pressing the power button and inserting your restore disk all at the same time. An Installer window will open, but do not proceed with any installations. Instead, from the Menu Bar, select Utilities > Disk Utility. In the Disk Utility window click First Aid, and then click Verify. If Disk Utility reports errors, click Repair. When Disk Utility is finished, from the Menu Bar, select Utilities/Startup Disk. Select MacintoshHD 10.x.x and click Restart.
    To check your hard disk’s S.M.A.R.T. status: Open Disk Utility, in the Utilities folder in the Applications folder.Select the disk in the list at the left, and look at the bottom of the window for a field named “S.M.A.R.T. Status.” Make certain it says; Verified If not, there's a problem with the boot disk.
    If Disk Utility reports errors it cannot fix, you have several options. You can get DiskWarrior or TechToolPro to repair the directory. The other option is to locate an Apple store or an Apple certified repair shop.
    You can also use Disk Utility to check to see how much free space there is. Select MacintoshHD 10.x.x on the left of the window, then look at the bottom of the DU window. The Capacity and Available disk space will be displayed there. Never allow the free disk space to fall below 10%, 15% is better. Insufficient available space, can cause performance issues, system corruption, and possible loss of data.

  • IMac G5 Graphic Card Replacement for blue screen problem

    When I turn on iMac, I only see blue screen, the apple technician said Need to replace graphic card,  Nvidia Gforce 7600GT 256.
    1, can it install in IMac?  Seem like it work for PC?
    2,  I had blue screen problem several time,  I think I turn on iMac too long, so it burn out graphic card.
    3,  I have 2007 G5 24" screen model,  is any durable and afford graphic card you recommend?
         Where to buy for cheaper price?
         Do I need to change mother board?
    4,  can I replace it by myself?  Any picture or video for graphic card replacement?
    Thank you.

    If you look around, you might be able to find someone who will replace just the chip on the graphics card, which is what usually fails. It will take someone highly skilled; they really have to know what they're doing--it's not an ordinary soldering job.
    Here's someone who found a non-Apple service to do this, and it proved to be far less expensive than a full logic board replacement. But I think this was in the UK.

  • Problem with split screen quicktime movie to iDVD

    hey folks, i've just spent two 6-hour renderings for naught and have the following problem:
    QT Pro 6.5.2
    iDVD 5
    OS 10.3.9
    I pulled together a Quicktime movie consisting of talking head interview, then split screen (two clips simultaneously), back to talking head, then split screen again, etc etc.
    the first time i rendered the composite Quicktime movie to iDVD, my split screen background was a sickly lime green color. blech
    so, i added a black slide in TIFF format ONLY to the split screen video portions. played around with the Layers property until my split screen video clips were in front of the black background. recut and pasted my full Quicktime movie again.
    However, upon my second iDVD rendering, a funny thing ocurred. Now, when the DVD gets to a split screen portion, the VERY LAST FRAME OF THE PREVIOUS TALKING HEAD CLIP freezes, and appears in the background of my split screen clips.
    What gives?
    I plan to do some testing, but sure would like to shortcut this problem, it's eating away at my weekend and i need to get this project done.
    thanks for any insight you can give

  • Late 2013 iMac 27 inch screen problems

    My screen has many marks on the screen which look a bit like rain globules.   They are particularly noticable when the screen is dark and is a particular nuisance when editing video and photographs.
    I have only tried wiping them off with  a lens cleaning cloth as I am reluctant to risk damaging the screen.
    Any ideas or is this a screen problem on this latest iMac screen.
    Am using Mavericks operating system

    Apple lists these environmental conditions for most of its machines:
    Operating temperature: 50° to 95° F (10° to 35° C)
    Storage temperature: -13° to 113° F (-24° to 45° C)
    Relative humidity: 0% to 90% noncondensing
    Maximum operating altitude: 10,000 feet
    Maximum storage altitude: 15,000 feet
    Maximum shipping altitude: 35,000 feet
    If you don't believe you are exceeding them up or down, you may have a hardware problem that your 1 year AppleCare may cover.  See first if the hardware test booting the 'D' key is revealing:

  • HT1338 I have a screen problem from my Imac 27

    I bought the used Imac 27 (2011 version)  from Amazon.com
    rightnow I got a screen problem. It is a grey side on my screen. In the beginning is perfect .
    After few months , my screen have a lot of dirts , and I can see the dark inside.

    Resetting PRAM and NVRAM
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • IMac 27" i7 "blue screen" problem

    Hello,
    My iMac "crashed" a few weeks ago and I experienced something resembling windows "blue screen". The screen went black/grey/blue. Rebooting the iMac did not help and after the normal start up procedure (Apple logo) etc. the mac stopped at a grey coloured screen. I called support and together we tried every possible way of restarting the system without success. It seamed to be a hardware problem like a defective HDD drive or maybe worse. I received a list over Apple service partner and delivered my iMac for a thorough inspection. After approx. one week the service partner called me and asked me "what s wrong with your iMac?" Apparently the iMac started without problems and the diagnostic tests did not find any hardware failures. I was pretty surprised that they didn't find any hardware failure. Happy that the iMac seamed to be ok I went home and plugged in the machine. It started without problems. Connecting the wireless key board I discovered that most of the F functions did not correspond to the symbols on the key board anymore. All functions like brightness, mission control, dashboard etc. had changed places. While trying to reset to the F functions to the normal set of keys while simultaneously updating iTunes and the latest security update in the background the iMac screen went black and grey... It started once after the crash and I checked the list of incompatible updates in the appstore before it crashed again...  Now the machine did not start properly and I got the same grey screen after rebooting the computer. I am relay disappointed.
    Anyone out there experiencing the same problem? Anyone who can explain what's wrong?
    I will have to call the Apple service partner again tomorrow.
    My iMac is approx. 3,5 years old. i7 processor running OSX mountain lion with a 2TB HDD.
    Best regards

    Thanks for helping me out rkaufmann87
    The iMac works at the moment and I have even installed the new OS X. I called the Apple service partner and they will look into the problem again. Now that they know what to look for I guess they will find the problem and fix it. Hopefully I will only need to change the HDD.
    Back to the keyboard. What has happened to the F keys? I need to push the fn key in order to e.g. change the volume on the internal speakers or change brightness! What has happened to the default keyboard setup?
    Best regards

    Hi Pedro,
    Yes it looks like particles all over the screen, for the moment they are gone. It has never happend on this new machine before and actually i'll hope that i never comes back, perhaps it is a Mac OS X Lion graphic jadda jadda issue =)

  • IMac Screen Problem?

    Hi, As you can see in the image below, there is this bright squiggly object in the bottom right corner of my iMac's screen. The computer is just under 4 years old. It is much more visible in person, and the artifact, or whatever it is, has depth to it, indicating to me that it is inside the screen or at least behind the glass. I have just started noticing this now. Any ideas? Thanks.

  • How to How to install ATI Radeon HD2600 driver on bootcamp 3.0 windows 7 partition w/black screen problem

    Ok....so i've posted this question in a different way, and i gotten several "scratch the surface" answers from people just saying to install "Ati catalyst", or insert the os x dvd and run set up.exe, and update  to boot camp 3.1 or 3.2...while these all seem like great suggestions, I am finding myself needing more specific direction or "hand holding" so to speak.....here is the MAIN problem...
    The Background/history
    I used boot camp (3.0, and i found updates for 3.1 for imac and for windows, but can't find for mac pro, AND they all are ".exe" files which run on windows..which as you'll see is the big part of my problem...So I recently updated my mac pro (with the ATI Radeon HD2600 graphic PCIe card with 10.6.7 from 10.5.8.  I created a single partitioned drive to install windows 7 professional 64 bit.  The download software function didn't work (Thanks, APPLE for that poor level of support) so have to select the option that i have already downloaded, or have other media with the drivers already on it....i restarted with the windows 7 disk in.... 
    The installation of Windows 7 Pro 64-bit
    So the installation of windows 7 seemed to go flawlessly, was able to use my existing 23" hd apple cinema display (so somehow it has drivers that work with the graphics card, or maybe the motherboard's on board video components) and i select english, and install now, custom, blah, blah, blah...installation causes a few reboots, then restarts ultimately back in os x since that is the default boot os i use on this desk top and have to do the "opt" button to select booting in windows....so when i try restarting in windows, now using the actual boot drive on which i am installing it, it ran through another reboot or two, but then after that, my display goes black....  in the communities, the solution sounds super simple... "go download the ATI catalyst for the black screen problem....windows 7 doesn't have device drivers that work with the ATI radeon hd2600...no problem, just go download and install...."
    The problem, re-emphasized :  I cannot even finish the install for windows, because of this driver problem....i cannot see anything....I have tried to reboot in safe mode, and that then seems to invoke whatever basic drivers that do work, likely through the motherboards onboard video vs the actual graphic card, and the screen works and says that it's wanting to complete the installation, so i'm thinking awesome this is gonna work....and then.. "windows installation was not completed and cannot be completed in SAFE MODE, need to restart, blah, blah, blah" pops up...and forces reboot...so Safe Mode allows me to see, but won't allow me to finish the install of windows 7...and without completing the install i can't run (ranther I DONT KNOW HOW TO) any of the various .exe files everyone is telling me are the solutions to my problem...like update 3.1 and 3.2 bootcamp...they're all .exe files?  not sure why, because bootcamp runs in 10.6.7 i thought, but whatever...it needs running Windows to execute...then the ATI radeon hd2600 driver for windows 7 that i downloaded from the site has an installation program that is an .exe file, which needs windows to run...  Does this make sense, why i can't just use these fixes, that seem to be the only fixes out there....so can someone school me step by step here (not just the highlights) of how to update bootcamp, and how to install the ati radeon driver  without having been able to complete the windows 7 installation because the monitor goes and stays black????
    This is so very frustrating for the record...and any substantial help "not just go download this..." would be immensely appreciated.
    Some other things i've been told to try that i've tried and nothing seems to happen as i'm told it will....
    ---I've been told to install the osx dvd and run "setup.exe"  - AGAIN...it's an exe file...and 2 - when i put in the os x file it just wants to re install 10.6...so need more help if this is even a real solution to understand how to make it work...
    ---I've been told to update boot camp to 3.1 and/or 3.2 from 3.0, using Apple Software Update....Well, my software update is saying everything is up to date and there is nothing new to download at all, and when i reverify the bootcamp version it is still only 3.0.2...and again downloading the updates from www.apple.com/support/  for 3.1 and 3.2...all of those are .exe files...need windows to run them...again, refer to the problem described in detail above...
    ---I've been referred to the black screen on imac early 2011 thread saying it should fix my problem...and reading it it SEEMED like the most promising resolution...it involves creating a boot flash drive for windows 7 and an xml file that sets the imac drivers to auto install during the windows installation..and it got me farther than anything else..but still ultimately ended up in the darned black screen...my assumption is that it's because it's for imac and not mac pro so not ati-radeon specific drivers....ok....that's enough..please...anyone who thinks they can help...your help is desperately needed...thanks so much in advance!

    hey Hatter, thanks so much for getting back...so just to be super clear...is there no way to install the drivers using an exe file given my current state? no way to do it with command prompt or something?  if can make work with existing card, i'd prefer it...now when you say it's 'toast' how do you mean?  it works well with the os x partitions and always has...so i'm not sure i follow, just want to be clear...
    Now to your point of starting with only the one drive installed...so i would put that bootcamp drive in bay 1 and disconnect the rest...i'm not totally sure what you're suggesting the effect should be of doing this?  just that i'm just installing windows without the bootcamp deal...but if windows 7 doesn't support the ati radeon hd2600, it still will go black screen no? or you're saying it will run video through the motherboard if it's the only bootdrive, and will run all the way through the windows install without trying to switch over to the hd2600?  (slrry flr these questions..just really want to make sure i understand what you're telling me..thanks so much for your patience and help by the way...it's very greatly appreciated...your support is priceless!
    So now, assuming none of the above is possible...referring now to the ati 5770 that you referred to...you mention it works with 10.6 well, and that windows 7 supports it ...2 questions on that
         1) Windows 7 supports" meaning, out of the box windows 7 supports it? or will i have to install drivers still through some update, because again, if that's how i have to do it, then won't work, cuz can't start windows to see anything to install any drivers or run any thing at all...so it would have to just work with initial installation.
         2)hardware wise for my Mac Pro 3,1...intel dual quad core xeon, blah blah....will this card work? it's a PCIe and should fit on my board no prob, etc?

  • When using firefox and each time I open a new tab I end up with a split screen and it is annoying. How so I fix it.

    I open firefox. Go to website then where there is a + sign I open a new tab. A new tab comes up but then splits the screen into two with a new tab in the middle and I end up with 3 small split screens in the one instead of 3 separate tabs.because it is doing that i cannot then get a full screen and go about my usual business. Lately there seems to be numerous problems with fire fox loading also. it continues to come up with page not found and try again. I hit try again and then it may find the page. these are on sites that I access daily and have done so for several years now. Never before have I had so much trouble with fire fox. Not only I but we have four computers accessing the internet ...have done for some time and never had this problem but everyone is suddenly experiencing the same problem. The only thing new that has been put on the main computer is a K9 protection thing recently and I am wondering could that have anything to do with these issues and if not is fire fox having tech issues . How can these problems??

    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.
