New MacBook Pros show flickering with 24-inch Cinema Display

MacBook Pro 2011 triggers 24in Cinema Display bug

Owners of the new 2011 MacBook Pro are reporting on Apple's boards that the portables have a unique conflict with the 24-inch Cinema Display. Both the 13- and 15-inch models, and likely the 17-inch model, produce intermittent flickering, brief blackouts and other periodic but noticeable flaws when attached to the out-of-sale screen. The built-in notebook display is unaffected.

Users have already tried some of the more common tricks, such as resetting the SMC, but haven't had any initial success. It also applies whether or not the AMD or Intel graphics are being used. Those with the currently available 27-inch Cinema Display also haven't mentioned the issue, though this is likely owing to Apple having tested on its current screen.

Apple hasn't yet commented on the issue and hasn't said whether or not it's a regular issue. It should most likely be fixed at a certain point by a firmware update for the Cinema Display, the MacBook Pro or both. The cause hasn't been narrowed down but may be related to early teething problems with the Thunderbolt port. Any standard DisplayPort device should behave normally when connected, but the new Intel controller chip and possibly different signalling could lead to issues that weren't present before.

    Separate frequencies?

    Two monitors, each a different setting, MBP sends same setting to each? Would be typical Apple double use of same code...

    Shocker

    What a total shock, a new Apple product hits the shelves and a fairly serious problem immediately crops up. I love Apple stuff, everything in my house is Apple, but one thing I've learned over the years is to never ever ever buy any new Apple product until at least 6 months have gone by for them to fix whatever issue crops up right after it is introduced. It's such a commonplace occurrence that it's almost a yawn to see headlines like this.

    17 inch has flickering with with 24 inch monitor

    I have the new 17 inch 2.3 8 gig ram and 256 SSD straight from apple and I have a 24inch monitor that I use as my primary monitor. I close the MacBook Pro and use the 24 inch as my primary. It has occasional flickering. I would say in a given 8 hour work day it will fo it a few times a day.

    Dang

    I have a 24 inch monitor. I guess I'll have to upgrade!

    Definitely had been thinking about it anyway.

    One of the reasons...

    ...that I gave up on Apple for notebooks is cr/p like this. It'll take them 2-3 weeks to come up with a fix.

    From the premium they charge for their notebooks, stuff like this should be rare and not nearly as common as it seems.

    Not a new problem....

    I have the previous generation 17-in MBP with said display and also experience the cited problems. It would be nice if Apple would finally address this.......

    obsolescence

    So it isn't just iMac users who have to throw away their screens when they want to upgrade.

    Like the above poster said, not a new problem

    This problem was introduced with 10.6.6. I get the same thing on my Nehalem Mac Pro. Usually a restart cures it. I have no doubt apple will fix this.

    re: Why would they have to do that?

    You can use the iMac as a secondary display to a new computer compliments of DisplayPort.

    Nope, only the 27" iMac offers that. None of the 'cheaper' models have such a thing.

    Oh yeah, and it's a full-fledged computer as well.

    And the point is that if you decide to 'upgrade' (or have to upgrade), you're getting a whole new computer, not just a new CPU.
