    There is an update now that specifically lists the flicker as one of the resolved matters. Use update in Mac OSX to get it and reply with your results. I don't have the flicker problem so I can't confirm it's. Fixture.

    Not home near my Cinema Display for a few days - but excited to hear this Mike.  Can you tell me if it came out in the last few days?  I only ask because there was a firmware update probably 2 months back that said it fixed the screen flicker but it didn't fix THIS one.

    It's became available a few hours ago.

    Same problem here (just adding my name to the list if this isn't getting the appropriate attention from Apple). Brand new 2011 17" MBP Pro (Thunderbolt) some upgrades - $4200 machine with a $900 monitor. Slightly older (DisplayPort) 24" Cinema Display and I can't use it - the flickering is (randomly) occasionally so bad I need to unplug and use the laptop directly.   Worked fine with my 15" 2008 Macbook 3,1 with a Displayport to DVI adapter.

     

    This is not up to Apple's QA standards - didn't they test this before releasing the Thunderbold MBP's?

     

    Downloaing 10.7.1 now - fingers crossed this solves things. Can anyone confirm it has?

  • gekkonaut Level 1 Level 1 (0 points)

    10.7.1 Fixed nothing. This is unacceptable, and a big big problem.

     

    Going down to buy a DisplayPort -> DVI adapter, as I already have a DVI -> DisplayPort adapter.

     

    It is a shame that Apple has done nothing about this yet - I thought these were supposed to be premium products.

  • Daniel Palmer Level 1 Level 1 (20 points)

    Not fixed with 10.7.1!

  • jkirker Level 1 Level 1 (0 points)

    This is a reall lame non-solution but it worked for me.

     

    Pick up a new mini-display port to DVI adapter and a new cable and try it. If it doesn't work send it or take it back.

     

    Sounds crazy but I haven't had an issue in months and I was one of the first to moan and complain about it the day the new mbp's came out.

     

    Try it and eliminate the reduculous amount of stress you are putting yourself through.

     

    I've got a MBP 15 i7 with an external Dell 27.

  • brandscill Level 1 Level 1 (20 points)

    I also have this issue

     

    Really getting annoying now and seems to have got worse with the 10.7.1 update!

  • Allison Sheridan Level 1 Level 1 (5 points)

    After my 4th "known issue, wait for a firmware update" call to Apple, I'm writing a paper snail mail letter to Apple.  Probably won't work either but something else to try.  Address I was told by a friend to do is:

     

    Apple Computer, 1 Infinite Loop, MS60-DR, Cupertino, California, USA, 95014

    Dear Apple,

     

    Please fix this LCD flicker problem.  Lion 10.7.1 and all the other updates have not fixed this issue.  We all paid a premium for a closed loop hardware & software environment and expect things to work very well with each other.  Allowing this problem to linger is not living up to the high standard the company has advertised itself as having.

  • rep1967 Level 1 Level 1 (0 points)

    Another "me too", but with my shiny new thunderbolt mac mini and my year old 24" ACD. All the same issues with 1s screen blackouts every few seconds, occasional screen split onto fragments. Driving me nuts. Never ever did this with my old 2008 mac mini. With the new mac mini the problems occur from start-up about 1 time in ever two to three but guaranteed not to be there if I lug all my kit to the Genius Bar. From searching posts, it seems the thunderbolt equipped macbook pro, mac mini and macbook air are all having identical problems with the mini display port equipped apple displays. **** you Apple and **** you thunderbolt for spoiling everything. This has been going on for months. When are you going to fix it or refund us???? At least acknowledge it's a problem and that you are working on it.

  • christos_gr Level 1 Level 1 (0 points)

    last night I installed the latest thunderbolt update from the software update tool (aprox. 60mb).

     

    10 minutes now with no flickerings.

    Good news? Only time will tell :-)

    I'll be around.

  • Allison Sheridan Level 1 Level 1 (5 points)

    You guys are going to be mad about how I got this fixed.  to recap:

     

    • 24" ACD worked fine on display port MBP, failed on new thunderbolt MBP
    • In June I called AppleCare about it, they said go to Apple Store
    • Went to Apple Store, they said, "known issue, wait for a firmware update"
    • Waited a month, called AppleCare again.  "known issue, wait for a firmware update"
    • Waited a month, called ApleCare again. "known issue, wait for a firmware update"
    • Waited a FOURTH month. got the same story.  Escalated to supervisor.  Much sympathy, "known issue, wait for a firmware update"
    • Wrote a paper letter to Apple
    • Called supervisor again, much sympathy. He suggest I switch to Customer Service.
    • Called Customer Service. Guy said he'd try to figure out why they're not fixing the problem
    • I told him when he called me back, the ONE sentence I couldn't say was "known issue, wait for a firmware update"
    • He called me back last week and said they'd decided to give me a brand new display. Not Thunderbolt, but 27". I was dumb enough to question why a new Display Port monitor would behave any differently but he was assured this would fix the problem
    • Today I received my new 27" ACD

     

    Just started testing it, can't be sure it doesn't have the same problem, but whatever happens I have a new monitor.  I can't say this would work for anyone else, but it seemed only fair to share the story with you.

    Thanks for the post, Alison. Sheer persistence eventually got you somewhere. Well done. Hope all goes well. If the 27" plays up too, let us all know.

     

    A potential fix suggested by another frustrated customer was to use a mini display extension cable which somehow might act by dropping the voltage slightly from the TB port to the ACD. I put in a 3m extension cable yesterday between my mac mini and 24" display and so far, no problems!!!

     

    I'll keep you updated
