27 Cinema Display flickers on cursor change

Hello,
I've recently purchased a 27" Cinema Display and hooked it up to my mid 2010 13" MBP. Everything works fine except for one really annoying thing: The Cinema Display flickers when the mouse cursor changes. I've done a thorough search through the community threads and haven't found anybody who's experiencing the same problem. Could anyone please tell me if they've run into this issue, and if so if there's any way of fixing it.
Thanks!

Might be related to the thread below.
To give you a quick summary, try either of the following:
- use your macbook's charger rather than the cinema display magsafe connector
- increase the brightness to 7 bars or more
- simply unplug the magsafe used by the cinema display

  • 27'' LED Cinema Display flickers when powering MBP and dimmed down

    The 27'' LED Cinema Display flickers (backlight flickers) in the following situation:
    * The display powers an MacBook Pro (e.g. later 2010).
    * The MacBook Pro is fully charged (i.e. power is not used for charging).
    * The MacBook Pro performs some GPU intense task (moving the mouse over the dock with magnification enabled).
    * The brightness of the display is dimmed down to one of the lower settings (one or two "bars").
    The problem disappears if the MBP is powered by an independent charger.
    We reproduced the problem with two different MBPs (13'' and 15'') and two different displays.

    Same problem here! I bought two brand new 27 inch Cinema Displays, one for work and one for my home office. Both showed the problem. I returned both, go replacement displays and both show the same problem. I am using them with a 13 inch MacBook Air late 2010. I use them with the MacBook's display lid closed and powered by the Cinema Display. The problem only occurs when the display brightness is at 1 to 5 bars. From 6 bars on everything is fine. I also noticed that the flickering is stronger when I USE the computer, i.e. dragging around windows, typing, etc. When I just look at the screen, the flickering occurs more sporadically. The flickering looks like a short switching off of the display light (a few milliseconds).
    I just tried the hint suggested in this thread and indeed, when I open the lid and have the MacBook running on batteries (not powered by the Cinema Display), the flickering is gone! So it really seems to be dependent on that.
    Please fix it, Apple! This is not acceptable for a premium-quality display! We have already done a good job narrowing down the conditions under which the problem occurs. You should easily be able to reproduce the issue like this:
    - use a MacBook (e.g. new MacBook Air) and turn it on
    - plug in all three cables provided by the 27" Cinema Display (power, DisplayPort, USB)
    - close the lid of the MacBook and re-awake it with an external keyboard so the Cinema Display will be the only display in use
    - wait a few hours for the Cinema Display to become warm (not sure if this is a necessary condition but it could be)
    - then, use the computer under low-light conditions and ensure the brightness is at 5 bars or less
    --> You will see the problem.
    By the way, the recent Cinema Display firmware update (to address the audio issue) did NOT solve this problem.

  • 27" Cinema display flickers when woken from sleep

    I've noticed that my 27" Apple Cinema display flickers briefly when woken from sleep.
    I have had the display for 8 months, and haven't noticed this before.
    It flickers (or flashes), just once when the display wakes when the computer is woken from sleep. It only affects the bottom third of the display.
    Once it has properly woken, and flickered once, it then works o.k.
    Has anyone else had this?
    Thanks.
    Bob.

    Yeah - I'm trying to verify that 100% right now. I know that I won't get full functionality from the TB dispaly (no TB, FW or ethernet on the back of the monitor) but if I can get video and USB between the Mac and the displays, that would be enough. I haven't seen any docuemtnation anywhere deatailing wether or not that TB displays will work with existing video cards / Mac Pro's, or if I'll have to do a full round of upgrades including my Mac Pro and the ATI 5770. And as you know, there are no TB video cards on the market at this time. My timing basically *****...
    My plan was to return the Cinema Displays while I still can, fall back to a spare Dell 21" that I have lying around the house for a few weeks (yukkkk..), and then figure out what to do with the TB diplsay as they get closer to release. I'm contempling upgrading my Mac Pro, but if I can stick with what I have, it would save me some cash.I woudln't even mind upgrading my video card, but I just dropped $2000 on these 2 Cinema Display's last week, and I feel like they are already outdated.
    PS - I am constantly selling gear, so resale value and having the "latest and greatest" are pretty important to me, hence the interest in the TB displays.

  • 23" cinema Display flickers and goes to black

    Hey all,
    I am running two 23" cinema displays and one of them is flickering and going to black. Here is a video of it.
    http://larskoerkemeier.com/MVI_0972.MOV
    The curved bands arent there thats just from the filming but what happens is the entire image shifts up very quickly and what you see flash on the bottom is actually the top. It repeats this a couple times and then turns off and then it repeats and after a couple times the display just stays off.
    System:
    Model Name: Mac Pro
    Processor Name: Dual-Core Intel Xeon
    Processor Speed: 2.66 GHz
    Memory: 6 GB
    Graphics Card: NVIDIA GeForce 7300 GT
    Thanks,
    -Lars

    Hi-
    Try switching the power adapters to see if the problem moves to the other display.
    Of course, reconnecting/double checking all connections is a good idea.
    Other than that, any references in Console/Logs regarding graphics driver errors?

  • 24" Cinema Display flickering and eventually going dark

    I am having a repeat of a problem with my Apple 24" Cinema Display. The symptoms are the display will go black and come back on (flicker) and sometimes it takes a few seconds for it to come back. All USB devices connected to the Cinema Display become disconnected from my MacBook Pro when this happens.
    Last time this happened it started slowly and as time passed it happened more frequently. When I brought it into the store they were able to reproduce the problem immediately. They replaced the logic board in the monitor.
    I contacted support again. The display is still under warrantee. They scheduled an appointment for me to bring the display in. I am seeing the same behavior where the frequency of this problem increases as time passes.
    I am concerned they will be unable to quickly reproduce the problem again and not fix it, or fix it and the problem will come back again in a few months. I am afraid that I will still be having this problem after the warrantee expires.
    I've purchased many displays over the years (including Apple) and this is the first time I have ever had a problem. I think I may have had a lemon.
    I originally posted in these now archived threads:
    http://discussions.apple.com/thread.jspa?messageID=12175983#12175983
    and
    http://discussions.apple.com/message.jspa?messageID=12311032#12311032

    Just a quick update. I brought the display into my local Apple store. After they reviewed the records from the previous repair and my description of the problem they believe it could be a power supply problem inside the monitor. The power supply may have caused the logic board to go bad. Replacing the logic board last time fixed the problem but the bad power supply ended up causing the problem to return.
    I let them know that I was concerned that this is a reoccurring problem and my warrantee expires in July. I don't want to see this problem come back after the warrantee expires.
    I'm not sure what they will do if that happens. I hope this problem gets fixed this time around.

  • External Cinema Display flickers when attached to MacBook

    This usually shows up with an iPhoto image on the desktop. Pixels in dark areas turn green and dance around. The pattern resembles dithering artifacts, and the affected pixels move when a browser window is moved around the screen.
    The flicker often devolves into flashing pink pixels and pink lines, eventually making the display unusable. Powering off/on or changing resolution has no effect, nor does "detect displays" from the Display preferences.

    Took it to the local Apple Store (remember to make a reservation next time!). After about 30 minutes, the display started its flicker (hooked up to a different machine, while the MacBook was hooked up to a different display).
    So it was the display that was faulty. The Apple Store promptly replaced it with a new one.

  • MacBook Pro thunderbolt show flickering with 24-inch Cinema Display

    Hello,
    I see other people are having this problem of the cinema display flickering and going completly black for a couple of seconds.
    Is this on Apple's radar?  Is there a fix pending?
    From what I can tell the problem was first reported 7 weeks ago.
    thx
    Lach

    I am having the same issue.  My screen will flicker at a steady pace about once every 3 to 5 seconds, the flicker its self is maybe half a second long tops. 
    Needless to say this is completely annoying!  Was not a problem until today, I thought I was lucky to have avoided the horror stories of Thunderbolt display problems.  This is another thing I can add to my growing list of annoyances with a $2400 computer.  It is sad really.  I can hook up an Asus netbook to my 1080p display with no problems but somehow one of the fastest laptops available has issues being hooked up to an external monitor. 
    I want to love my MacBook but unfortunately it has been annoyance after inconvenience after just plain silliness with this computer. 
    Please fix this Apple.
    The monitor I use is a 23" Samsung 1080p display through a Thunderbolt to DVI connection.

  • Cinema display goes black upon resolution change in Windows XP

    Greetings
    Earlier today, I updated my ATI X1600 Radeon to the latest Windows Catalyst drivers and to the Catalyst Control Center from ATI. Even since, whenever a Windows application (games, in this case) tries to change the resolution on my external Apple Cinema Display (designated as the main monitor in the ATI Catalyst Control Center, with the MacBook Pro display disabled), the display goes black, and the monitor power lamp starts to flash.
    If I unplug the external Cinema Display from my MacBook Pro, my MacBook Pro display activates, and displays whatever it is I was trying to launch, so the problems is somehow related to the Cinema Display, even if the new drivers are causing it.
    This happens regardless of my Catalyst Control Center settings, such as scaling the lower resolution to fit the screen, or keeping it the original size, with black borders around. The problem does not occur when I launch games using 1600 x 1024, the Cinema Display's native resolution.
    Any ideas what might be causing it, and how to resolve it?

    Update on my situation: when I tried to change the resolution manually in Windows, I encountered the same problem. Now, whenever I connect the Cinema Display to my MacBook Pro, the same thing occurs: the screen goes black, and the power lamp starts flashing, even though I've changed back to 1600 x 1024.

  • Upon restarting my computer (which runs OSX 10.6.8), one of my 23 inch Cinema Displays is flickering like crazy.   Please help!!!

    I use two 23" apple cinemas displays with my MacPro.  Several times in the past, when I've restarted the computer one of the monitor is flickering as soon as it powers up.  One of those times I shut the computer down again right away and restarted and the problem went away.  Another time it stopped after sitting for a while.  But it has just happened again....and this time, no matter how often I restart, or how long I've let it sit, the monitor continues to flicker.  Any suggestions would be greatly appreciated. 

    Hey SGOWriter1,
    I found a document that can help with external display issues. I would concentrate on the troubleshooting steps in the "No video or no signal, image distortion, "snow," or flickering" section:

  • Using my macbook alternately with cinema display and without makes all my screens shift and change in size ?!

    After I disconnect from the cinema display and than a few minutes later open up the macbook without the display connected, things are fine. But re-connecting to the display, all the screens are moved and/or changed in size. Anybody any ideas ?

    I'm currently sitting in my office using my MBP and looking at a 24" Samsung display. At home I replaced my 4 year old iMac with a 2 year old 13" MBP which is connected to a similar display. That should be tell you all you need to know! 

  • 24" Cinema display is flickering every 30 seconds or so. Has anyone found a solution?

    I have a 2009 Power Mac tower with a 24" cinema display also 2009. About a year ago the display started flickering, like it was turning on and off. I've got a duel display set up and the other one (older acrylic 20") works fine. I've checked the cords, updated to the latest soft wear, at least I think I have. I see others having the same issue. Has anyone found a solution? This is really annoying when trying to do graphics work. Any help would be much appreciated

    Hi 517 Design, 
    Thanks for visiting Apple Support Communities.

  • HT1338 Today when connecting my MB Pro Retina Display to my 27" LED Cinema Display instead of mirroring (which worked fine in the past) both screens are black with a large arrow cursor. I'm unable to resolve this. Anyone have a similar experience?

    I think what may be your main issue here is that the 2011
    server has the Intel integrated HD3000 and is is struggling
    to run both a Thuderbolt display and a second monitor.
    When looking at specs for Thunderbolt Display, it is stated
    that the 2011 Mini Server can only support one.  Adding that
    Dell monitor with 1920x1200 display may just be too many
    pixels for the HD3000 to handle.
    You may want to try setting the Dell to a lower resolution
    to test the theory to see what happens.  It is however,
    possible that any additional monitor when using the Thunderbolt
    display may over tax the HD3000 graphics.
    FWIW personally, I have been running a 2011 Mini Server w/ Thunderbolt
    display for almost a year now without any issues.  However, I don't
    use a second monitor.

  • 24-inch Cinema Display and Mid-2010 Macbook Pro - Cinema Display still flickers after updates

    I currently have a 15-inch Macbook Pro (mid 2010) hooked up to my 24-inch Cinema Display.  I have updated all the firmware for both the Cinema Display and the Macbook Pro but still get intermittent flickering.  Moreover, I have cleared the PRAM and VRAM.  I have done ever possible update I can find, the system is fully functioning.  Help?

    I am having this exact same problem.  2010 iMac with NVIDIA GeForce 9400 256MB.  I have it hooked to a 30" display through a DisplayPort to DVI-D adapter.  The 30" is fine, but I have graphical corruption constantly on the main iMac screen.
    This all started as soon as I updated to Yosemite a couple days ago.
