    I have a similar problem with my imac. 23" 2011. I5... After it goes to sleep. Thunderbolt display comes on and off, on and off. It's driving me nutz. This kind of nonsense would never happen if Steve Jobs was in there cracking the whip!

    Correction, It's doing it now, without it going to sleep. I've turned off auto brightness. Something I don't want to do.

    maybe this is why Apple dumped ATI radeon out of their products. Or could this just be an Intel Issue? Maybe it's Intel and the uncompetitive business practices. Making the graphics by AMD not play nice with their crap.

    I'm really starting to HATE INTEL. And if Apple doesn't fix this. I'm going to stop loving APPLE

    I just updated my MAC OS to the latest 10.8.2. I dropped the resolution and turned off sleep mode. We will see if it keeps doing it.

    you can click on displays, gather displays. click on the thunderbolt display window, and reduce your resolution to the lowest value. There must be a limitation/glitch on the Radeon device when it outputs though thunderbolt at certain bandwidths.. Also. I'm using a OWC shielded thunderbolt to DVI connector to a Dell 2001FP in 90 degree portrait(long ways) 1008x1334 res.

    Same issue, 2011 Macbook Pro and TB display.  Genius diagnosed (apparently incorrectly) the issue to be the logic board on the laptop. They replaced it. 4 days later I took it home tonight and still have the same issue, I did a fresh install of Mountain Lion before taking it in to see if it may be software related, ran updates etc.  Same issue. I installed Lion today, same issue.

    If I open the laptop and wake it I need to unplug and re-plug the TB cable for the display to turn on. I'll make another trip to the store (an hour each way) to see what they suggest next.

    On my retina mbp, I have an ethernet adapter in one thunderbolt port and a DVI adapter for an external monitor in the second thunderbolt port. When waking from sleep, the external monitor will not wake up, though the mbp still acts as though it is connected. (it's a Samsung, which actually displays 'video mode not supported' when in this state)


    Unplugging and replugging the display adapter does nothing -- what does work (though annoying) is unplugging the ethernet adapter, then unplugging and replugging the monitor adapter, and then plugging in the ethernet adapter again. I suspect it's not the ethernet adapter in particular that's the issue, but rather that the monitor needs to be the 'first' thing plugged into the thunderbolt bus?

    I have tried several things including using a seperate Tbolt cable to the TB display. What I am down to is if I put the display to sleep but not the computer it works just fine but when the computer sleeps the TB display will not wake and the peripherals attached to it do not function. I have a MB Pro and an MB Air and the same problem exists on both. If the machine is open the onboard display works without a problem on both machines. I can let the machine sleep if the TB display is disconnected before it sleeps and the machine awakes before the TB display is reconnected. My workaround is to set the machines to not sleep when on power and to sleep on battery and for the interim this is working but a fix is needed sooner rather than later.

    Just recently started having the same issue, MB Pro 2011. I have the computer on a chill pad and it still seems hot like the video board is having trouble keeping up with the Thunderbolt Display.


    I will try switching off the sleep mode while powered up and see if that helps.

  • MacUsernameX Level 1 Level 1

    Another dissatisfied Thunderbolt user here. Never know whether it will wake up or not. Can't believe they aren't coming up with a fix for this.

  • MacMaik Level 1 Level 1

    Apple fixed my problem!!!


    First the LB was replaced - that did not help. Finally they found out, that the data cable was broken.....

  • ATLmetal Level 1 Level 1

    Same issue here. I have to unplug the display and plug it back in in order for it to turn on after my MBP goes to sleep. Come on Apple, how long are you going to allow this?

  • IP printing ***** Level 1 Level 1

    Add me to the list. I'm a very disapointed Thunderbolt display owner. I just bought the whole set up. Macbook Pro reina and thunderbolt thinking I was going to get pure apple beauty...I'm extremely dissapointed as an apple use and an apple share holder.
