New 27" thunderbolt flicking to black

Hi all. I just dropped $1199 on a new 27" TB cinema display to pair with my MBP.
Unfortunately, i'm having the same issues I had with an older 30" cinema display on the same lapto: when using Photoshop (cs6, in this case), and zoomed in, the screen flicks quickly to black then back to colour, intermittently, very very often, making it unusable for any work in Photoshop. It also makes a sound (the display) when flicking from black to back.
Laptop specs:
Osx 10.7.5
2.3 GHZ i5
16gb DDR3 1333mhz
It's a 13" Macbook pro from about 2 years ago.
Cheers

Hi guys, this problem is still ongoing. It's really not good enough for a brand new display. The problem occurs at all times, but far far more regularly and with shorter latency when Photoshop CS6 is open.
Any insights would be thoroughly appreciated. The display is 2 weeks old.

  • How do I get rid of random screen flicker and black screen when using a late 2013 Mac Pro with a 4k Samsung 55" Display?

    I have a new Mac Pro late 2013 and a 55" 4k Samsung display connected using an HDMI cable. For the most part the display is amazing, however, I get occasional screen flicker and black outs. Can anyone help? Could I possibly have a bad video card?

    4K displays take more than half the bandwidth of a ThunderBolt Bus. So you may get better results if you are careful to place them on their own Bus. This article has the explanation of which port is using which Bus:

  • New 27" Thunderbolt Display Flickers when attached to new 27" iMac

    I'm using a new 27" iMac. I require a dual-monitor configuration so yesterday I purchased a new 27" Thunderbolt display and plugged its built-in Thunderbolt cable into the Thunderbolt port of the iMac. I now have a huge desktop space that spans two monitors. With that in mind…
    At least once every few minutes the new Thunderbolt display blacks out (i.e. flickers) for approximately one second. The symptom is very similar to what a Windows-attached display does when the screen resolution is changed. A quick Google search indicates others are experiencing the same problem although most complainants are using a MacBook or Mini, not an iMac.
    Apple posted a firmware update for the Thunderbolt display a few days ago. I installed it successfully but the problem remains. Any advice?

    UPDATE:
    I received a call back from a senior tech at Apple. The salient points are as follows:
    (1) Apple engineers are well aware of the problem.
    (2) They plan to release a firmware update for the display at some indeterminate time.
    (3) The fix for this problem will not be bundled into the forthcoming 10.7.2 Lion update.
    Given that the flickering problem renders the Thunderbolt monitor virtually unusable as a desktop extension for a 27" iMac, combined with the fact that Apple has no idea when a fix for the problem will be available, my decision to return the monitor for a full refund is a virtual certainty.
    AppleCare objected to my conclusion that the Thunderbolt monitor is "incompatible" with the iMac. Perhaps they're right. I'm not super technical so it's possible that I used the wrong term. It's a semantic distinction though. The bottom line is that Thunderbolt displays flicker when attached to a brand new 27" iMac and my personal opinion is that one is better off not purchasing this device until Apple fixes this major flaw.
    Apple asked me to make a video of the Thunderbolt display manifesting the problem. Here it is.

    You can't. Theoretically, Thunderbolt devices that only transfer video and audio should work with Mini DisplayPort MacBooks like yours, but it's not the case of the Thunderbolt Display. Its firmware doesn't allow it to be used with non-Thunderbolt Macs, so you can't use the Thunderbolt Display with the Mid 2010 MacBook Pro.
    Instead, you have to look for another screen, or you can get an adapter and connect the MacBook Pro to a TV

  • Can I use the new Apple Thunderbolt  to Firewire adapter to download video from a video camera by firewire to my Macbook Air ?

    Can I use the new Apple Thunderbolt  to Firewire adapter to download video from a video camera by firewire to my Macbook Air ?

    Yes, you can use the 85 watt adaptor. You cannot use the new adaptors because your computer is not equipped with the proper MagSafe connector. But you can use the older MBP adaptors as well as a 60 watt replacement adaptor. All can be found at Apple's Online Store.

    The only way to get it back is a hard reset or let the battery die and then plug in the charger.  The brightness is up and the power stays on while screen is black.
    This is the second macbook pro i have owned in the past two weeks.  I am ready to return it for good if this is a chronic issue. Please help if you have had this same issue.

    Try a SMC reset:

    Hello QuinnDev,
    Thank you for posting in the Apple Support Communities.  It sounds like you are trying to use your MacBook Pro with a Thunderbolt Display in closed clamshell mode (MacBook Pro closed), but sometimes the display doesn't stay on.  I found an article that talks about closed clamshell mode.  You would have to fulfill the following requirements to use your display this way:
    Requirements for closed display mode:
    Power adapter
    External keyboard, mouse, or trackpad
    External display
    You can find all the steps and the full article here:
    Mac notebooks: How to use your computer in closed clamshell (display closed) mode with an external display

    I hope this helps!
    All the best,

  • 2 external monitors on new 27" thunderbolt iMac

    I have bought one of these new 27" thunderbolt imac. Is it possible to use both thunderbolt ports to connect the iMac to 2 external monitors?
    I mean, working with 3 monitors?

    In theory.  Note there may be limitations imposed by the GPU, which are in the specs:
    http://www.apple.com/imac/specs.html
    Any of those limits may be able to be overcome to some extent by devices by:
    http://www.matrox.com/
    Although I've heard their devices can be slower than machines that have the GPUs to support additional displays.

    Hi,
    my macbook screen goes black at random points when I am using it. I know it is still running as music continues to play and I can vaguely make out the content of what is on the screen. Sometimes the screen will flicker between black and normal. Can I fix this?

    Emily..
    Could be the graphics card, run the Apple Hardware Test
    If the hardware test doesn't reveal any problems, use Lion Recovery.

  • New 27" thunderbolt display

    new 27" thunderbolt display hooked up to late 2009 27" iMac will not work. I tried the PRAM reset and switched the power cords. Display will not even light up at all. Just bought the used iMac from Simply Mac. New display from Best Buy.

    The late 2009 iMac uses Mini DisplayPort. It does not have a Thunderbolt port, so cannot drive a Thunderbolt display.

  • LR3 can't find files after copying my previous hard drive to a new Lacie Thunderbolt drive

    I transferred my LR3 files from my WD hard drive to my new Lacie Thunderbolt drive and now I can only get the preview and it says the file is missing.  Is there a setting I need to change that I am not aware of?

    You have moved your image files outside of Lr (via your OS) and now Lr has lost the connection to your images. This happens every time you move images outside of Lr. Lr stores in its catalog - among all the other things - also the location of your images, and if the location stored in the catalog is different than the situation onyour hard drive you get the "missing" file message. "Missing" means that Lr does not "know" where your images are.
    You have to point Lr to the location of your image files to fix the broken link.
    In the Grid View (left side) in the folders panel you should see question marks in front of the folder names. That is Lr's indication that the link to the folders is broken.
    Go to the top-most folder in the hierarchy of the folders that show the question mark and right-click it (click with the right-hand button of you rmouse). Select <Find missing folder> in the fly-out menu, navigate to the coresponding folder on your LaCie and click on it. Lr will then also find the sub-folders under that folder on idt own - provided that you have not changed the folder names or the folder structure.
    If you have done that you have to "point" Lr to each folder individually with the procedure described above.
    BTW you will also get the "missing" message when you open Lr but your external drive is not switched on.

  • Pavillion dv7 new hard drive goes to black screen with cursor

    A couple weeks ago my computer suddenly started going realy slow so I rebooted, and it wouldnt boot. Just gave me an error in the upper left corner (I dont remember the exact message). Anyway I took it to a family fried who fixes computers he said the hard drive probably had a bad boot sector. We couldnt boot to it, but he could read from it by plugging it into his own computer like an external.
    Anyway we got the new hard drive in (upgraded from 320g to 500g) as well as the old one with the intention of making it a slave drive.  I tried putting in a windows 7 install disk (originally had vista), when I turn it on first I see the hp splash screen, then it says "windows is loading files" and goes to a "windows is starting" splash screen. After that its just a black screen with an arrow cursor and doesnt appear to be doing anything else.
    Any idea what the problem might be? Is it just trying to install to the wrong drive? Or could something more serious be wrong like the processor or motherboard that would mean the whole thing is trash now?
