Flicker between 22" ACD and MacBook Pro 15" i7

I recently connected my MacBook Pro 15" (i7, 2.66GHz) to my original 22" LCD Cinema Display via Apple's mini-DVI adapter to the ACD's DVI connector and am getting a regular flicker that I cannot seem to fix. It is killer on the eyes and any suggestions would be welcome.
Here's what has NOT worked:
- resetting the SMU
- changing the resolution (tried all of them)
- restarting with everything unplugged
- putting the machine to sleep, etc.
- running software update with the monitor connected (no updates)
Any suggestions or similar experiences? This is truly frustrating and I'd appreciate any insight as to a possible solution.
Thanks!

Hi, for me the same story MBP late 2010, and on an additional 22 "monitor, occurring in 10 sec flashes and of course flikering. Any help would be welcome. is an experiment all sorts of what is listed on the forum are of no help.

  • Syncing mail between iMac G5 and Macbook Pro

    I work at home on a G5 and regularly read and then delete or file my emails. I regularly sync between my G5 and Macbook Pro, which I use when traveling. My syncing routine works fine with the address book, calendar, etc., but when I go my Macbook Pro Mail account after syncing, the inbox is still full of mail that I have already read and filed on the G5. Is the syncing routine designed to replicate the mail accounts or do I need to reread, delete, and file the emails on the Macbook as well.
    PS: I am using email accounts with cox.net, i.e., not mac.com accounts.
    Thanks for any help.

    The underlying issue here is that you have chosen to use POP3 rather than IMAP mail accounts. Only IMAP mailboxes are 'synchronized' by default: it is virtually impossible to synchronize POP3 mailbox content.
    For a discussion of POP3, IMAP and mail synchronization options, take a look at the Mail & Address Book - Tiger forum located here.

  • How do I sync Pages and Numbers between my iPad and Macbook Pro?

    I know there is a way to use iTunes to sync my Pages and Numbers files between my iPad and Macbook Pro, but I can't seem to find the app or software or instructions. I've searched iTunes and all I've found are the apps that I already have installed on my iPad. Can someone tell me where I can find the right downloads and instructions? Thank you.

    The exact same way as in the old version.
    Option 1) Select the content desired to sync and sync.
    Option 2) Drag and drop the content onto the device.
    If the side bar is needed/desired, typing Cntrl + S will display it.

  • How do I sync my icloud calendar between iPhone 5 and macbook pro without a 1 hour difference? I've made sure that the time zones are the same on all devices and it's still doing it.

    I cannot get my iphone 5 and macbook pro to display the same time on my calendar. There is a one hour  difference between them and it is driving me crazy!! Please help!!!

    Did you also confirm that the time zone was set correctly on icloud.com (click on your name, check Time Zone)?

  • Handoff won't work between iPad Air and Macbook Pro

    I'm trying to get handoff to work between my iPad Air and Macbook Pro (Late 2013). I have tried turning all devices on and off again, turning the handoff on and off again and turning iPhone Cellular Calls on and off again on both devices.
    Does anyone know how to fix this issue?

    This fixed your connectivity problem. However, I don't think this has actually fixed any problem.
    I think this Handoff feature is buggy. I have three devices -- a MBP, an iPad Mini, and an iPhone 5 -- and I have done "the dance" you've described and only one of my devices, the iPhone, is now Handoff capable. The iPad Mini still doesn't support Handoff.
    I think there is a problem in the software and that all of this signing in, signing out, powering on, powering off, is just getting the devices to clean themselves up so that stuff can start from a fresh slate and attempt to work together again...sort of. It's not necessarily guaranteed.

  • Sharing Files between Windows Vista and Macbook Pro

    Hi everyone!
    I have just bought my first Macbook Pro and I love it. I am running Windows Vista on my desktop and connect wirelessly to the internet via a Netgear router. I have managed to connect to the internet with the Macbook Pro wirelessly too.
    I am not sure how to set up file sharing between the PC and Macbook - can anyone point me to some SIMPLE instructions please?
    Many thanks

    this is a wonderful article! thanks so much!
    only one small change though. you don't really need to create another user ID to access the windows machine. i used my existing ID and it logged on fine!
    but still, thanks for the rest of the article. i was totally lost without it...

  • Sound Switches Between Thunderbolt Display and MacBook Pro

    I have an Apple Thunderbolt display and MacBook Pro set-up with dual screens. I have an iPhone plugged into a dock that runs to the display. When I have music playing out of the display and I disconnect my iPhone, it switches the sound to the MacBook Pro.
    1. How do I stop this from happening?
    2. If I can't stop it from happening, how do I move the sound from the MacBook Pro back to the display?
    There doesn't seem to be any options within Preferences/Sound to change it back.
    Thank you.

    I've a Spyder4Elite that I use on both my Thunderbolt Display and on my MBP - and, while both are calibrated, they don't - and cannot - 'match' one another, no matter how hard I try.
    I suspect that you're running up against the same wall? Different technologies in different displays. I doubt that you'll ever get a perfect match: mine are just 'good enough'.

  • What's the best way to share my Aperture and FCPX projects between an iMac and MacBook Pro?

    Greetings,
    I own both an iMac and MacBook Pro and I'm interested in figuring out the best way to have access to my iTunes, Aperture and Final Cut Pro X files not only when I'm at home using the iMac, but when I'm out and about with the MBP.
    I'm sure there are others among us who require a similar setup so I was hoping you guys could share with me how you solved this little problem, and also inform me of any potential negatives for your method so that I'm well prepared. Thanks.

    Best is a subjective term, as it will ultimately come down to preference. The fastest however, would be to wait until they market has a few thunderbolt drives available for purchase...
    But like the first poster stated, a firewire 800 drive, would be the more convenient choice for now. Or you could set the shared folder on your iMac to be avaible on your network and use it to allow your MBP to access it wirelessly.
    Obviously whatever you change, just save it back to the same folder on the iMac. Keep in mind it will not be as fast as the first suggestion (unless it is a wired network), but may be usefull for smaller files.
    However, you should have everthing backed up via an external drive, that is always useful...

  • Share cinema display between Mac Mini and MacBook Pro

    Hello -
    I am keen to get an LED cinema display to use on my new MacBook Pro - but I share my study with my children - so want to give them a MacMini to use.
    How easy is it two swap between the MacMini and the MacBook Pro ? I guess there is only one input in the LED cinema display ???
    Thanks in advance.
    Andrew

    Interesting - I have the same idea: sharing a 24" cinema display between a Macbook Pro for myself and a Mac mini for my wife.
    The only problem I see is that the display doesn't have any Firewire ports. So if I want to use an external harddrive (or a mini-DV camcorder) on both computers when connected to the display, then I'd have to plug that into the computer instead of the display ...

  • Syncing Notes between Iphone 3GS and Macbook Pro

    I've read all the forums I can about this, but can't seem to find the answer.
    I want to sync my notes between my Iphone 3GS and my Macbook Pro. Right now when I add a note in my Iphone it automatically is added in my mail account in the Macbook.
    However, if I add a note in the Macbook, it does not get added to my Iphone.
    I'd like it to go both ways. Is this possible?
    Thanks!

    This forum is really for the MacBook Pro hardware, not for iPhone issues. I think the best place to ask this question is here:

    The issue is with configuring your iPhone. I personally gave up trying to make it work.

  • Syncing messages between iPhone 6 and Macbook Pro

    Hi Hawgjohn,
    The new continuity features with iOS 8 are awesome, but they do take some setup to work properly.  Luckily Apple has a big guide on how to set up all of the continuity features (including text messaging from your Mac) here: Connect your iPhone, iPad, iPod touch, and Mac using Continuity - Apple Support.
    Browse through that article and find the section that is relevant to your issue and follow the instructions
