Thunderbolt display image snowy

I have my macbook pro (13-in, mid 2012) connected to a thunderbolt display with a second thunderbolt daisychained to the first. I am running OSX 10.9.
Sometimes when my macbook goes to sleep because I have stepped away and I come back and wake it up, one of the thunderbolt displays has these snowy pixelated segments that appear on the screen. Sometimes unplugging and replugging in the thunderbolt cable will fix it, and sometimes I have to do a complete restart to get it to go away.
Any ideas what may be causing this or what to try to fix it?
Thanks!

Thunderbolt Display - Image stopped working over night, while in sleep mode

Hi All,
Wondering if anyone has this problem?
Been using TB display fine for over a year. Connected into it are a couple of external usb hardrives, TB WD backup (which has a mini-HDMI monitor connected into it). The monitor has always worked well with the clamshell closed - seems like previous updates have fixed the odd phantom decision of which monitor should come on and when.
Over the night, after putting the monitor into sleep mode, when I woke it up all systems kicked on (I could hear the external drives working and the other external monitor turned on), but no image came up on the TD display. My macbook thought it was on, as I could sweep my mouse over into it and initiate programs on that screen (but just not see them).
I unplugged everything from the display - still same problem, no image. When I open my macbook up, while connected, it again thinks the display is active but there is no image. When I sweep out, my macbook thinks the in-computer display is "Display 4".
Because of the previous nuances with the TD display, I'm hoping hope that this is a software issue, but it kind of seems like hardware.
Any insights would be great!
Thanks

Another update for you all....
While watching a movie on the TV yesterday the Mac Pro and Thunderbolt display went to sleep and once again when I tried to wake them the screen was totally black. I called Apple again and the only thing they could suggest was to take the screen to an authorised service provider so that they can run tests.
After going through the resetting of just about everything I got the screen working again.
I then trawled through forums on various sites and can see that this is quite a common issue - especially if your connected computer is running Mavericks.
Other solutions which people have used are plugging the power plug for the Thunderbolt display into a totally different power source (if that's possible in your set up). Thankfully for me it is.
Another suggesttion which has worked for others is to disable the Power Nap feature within the Energy Saver perference pane.
I did both of those and for the first time this morning the Thunderbolt Display woke up when I woke the Mac Pro!
However I did get an error message that he system had recovered...

Doing more digging in the internet I found this article
http://sysadminblogger.wordpress.com/2013/12/02/os-x-mavericks-wake-for-network- access-with-no-random-wake-ups/
So I am now thinking that not only has power nap been causing issues with the display but wake for network access is also not really working as Apple intend it to.
As I am a home user there really is no need for me to need wake for network access enabled anyway so I am also going to disable that. Hopefully this will mean that I have no more random phantom wake ups which I think may have been the cause of this issue all along.

TS4080 apple thunderbolt display image on display intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys. Rebooting by pressing the power button resolves issue.

My apple thunderbolt display (which I purchased 1.5 years ago; OS 10.7.5 Mac Mini) intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys, so am thinking it is a hardware problem with the display. Rebooting by pressing the power button turns the screen back on, but the same phenomenon has occurred several times. Could this be a software issue, or do I need to have my display repaired? Your feedback would be appreciated.

Hi ED, tough to tell, but it does sound like it's waking with the bonk, just not displaying.
Long shot but...
I wonder if it's a variation of this, of which I've seen many different symptoms...
Resolution
Move the mouse or trackpad cursor over the center area of the login window so you can see the user icons. Click on the icon of the user that you would like to login as, type in the user's password, and press Return.
If the login window is configured to show only the name and password fields, type in the user's name and password into the fields, and press Return (even if you cannot see the rest of the login window).
Additional Information
This issue will not occur if the display is not sleeping when the account is logged out. Use the steps below to confirm that the account is not configured to log out automatically while the display is sleeping:
1. Open System Preferences > Security & Privacy > General. Click the padlock to unlock the preference pane and enter your admin password. Click the Advanced button at the bottom, then see if the option "Log out after N minutes of inactivity" (where N is the number of minutes) is enabled.
2. Open System Preferences > Energy Saver and configure Display Sleep to occur after the account is logged out, by dragging the slider to a number of minutes that is greater than N was set to in the previous step.
Important: If automatic log out is not needed, disable "Log out after Nminutes of inactivity" in System Preferences > Security & Privacy > General. This will also prevent the issue.

How do I get steam games to run on my thunderbolt display instead of the macbook screen

I can't get steam to run on my thunderbolt display, only the Macbook display...??

Hi, I just got an Apple Thunderbolt Display. How can I connect it to my sony vaio pc? Thanks

Hi, I just got an Apple Thunderbolt Display. How can I connect it to my sony vaio pc? At Apple Store they gave me a Mini Display Port to VGA Adapter, but monitor doesnt display any image. Thanks for your help!

no, your computer needs to have thunderbolt technology. does it?
if not, no adapter can make a thunderbolt display work on a non-thunderbolt computer.
someone was likely confused since miniDP will FIT into a TB socket but is only compatible one way, ie a mDP display can work on a TB machine, but a TB display cannot work on a mDP machine

No sound from Thunderbolt Display after update to OS X 10.9.3

So I updated to 10.9.3 this morning only to find there is no sound coming from my Thunderbolt Display after installation. Sound is now only audible from my MacBook Pro (late 2011). Also, see image below, there is no sign of any connected inputs other than my MBP now. I've shutdown and restarted a number of times, but still no audio from the display.
Really starting to wonder why it's worth spending so much on Apple products now...

I sent my TB Display in for repair. They had it almost a week and didn't find anything wrong with it. Instead they took in my MacBook Pro and replaced the logic board (2nd time it had been replaced) and the Display seems to be working fine now.
...except that for using 3rd party video conf apps, those apps only pick up the MBP camera (even though i try to change settings in app), not the TBD camera... but FaceTime and Skype find the TBD camera.
Strange.

I completely agree with that sentiment. That's why we pay through the nose for their products, so it feels very bad when they don't just work.

Can I daisy chain two Thunderbolt displays to the new MacBook Airs (July 2011)?

I have last year's MacBook Air -- probably the best Mac I've ever had and I've had a few. I looked at using multiple displays last year, but the reviews for the major 3rd-party solutions really demonstrate how little is possible.
I see Apple says you can double up on displays for the MacBook Pro (I have a pre-Thunderbolt one unfortunately), what about the new (July 2011) MacBook Airs?
Anyone tried? Anyone know?
(I have a 30" Dell display, but it is, and always has been, very flakey when it comes to connecting to a Mac laptop).

You can thank Intel for that.
The sandy bridge chips all have integrated graphics, and before they were released -- they took nvidia to court claiming they didn't have a "license" to make GPU chipsets for the sandy bridge line. Intel won, and consumers lost.
The solution most manufacturers are using for notebooks is graphics switching (nvidia optimus like technology) -- which basically uses a discreet GPU along side the intel integrated GPU, and switches between the two instantaenously based on the workload and \ or battery life -- this is how the macbook pro's with the ATI gpus work.
Since there isn't enough space physically inside a macbook air for a discreet GPU, and since no company in the world is allowed to make a shared GPU for intel's sandy bridge chipsets -- the only solution is to use the integrated graphics that is in the processors -- Intel HD 3000. Intel basically has the monopoly here...there is no legal solution in the world another company can provide thanks to our wonderful court system
Wanna know the really sad part about the Intel HD 3000 GPU? The Nvidia 320M (the GPU used in the previous model 2010 macbook air -- chip was released to the market in April of last year) actually out performs it in some benchmarks -- that's right, a 1+ year old shared gpu from nvidia outperforms Intel's 2011 integrated graphics.
Intel ***** at graphics, period.
The only other solution I can think of is for you to get the "Echo Express" product from Sonnet:
http://www.sonnettech.com/product/thunderbolt/index.html
It's basically an external bay that will allow you to put a PCIe GPU inside it, and it would then connect via thunderbolt to the macbook air.
You would then use the minidisplayport connectors on the PCIe GPU to connect to the apple displays -- I believe any modern ATI or Nvidia GPU can support up to 3 or 4 external displays.
Unfortunately, sonnet's bay is not released yet, and you'd also have to make sure the PCIe GPU you get supports both thunderbolt AND os x....so yeah, kind of slim pickens right now
EDIT:
So apparently the macbook pros can daisy chain two thunderbolt displays -- Apple has a picture of it on their site:
http://storeimages.apple.com/1867/as-images.apple.com/is/image/AppleInc/MC914_AV 7?wid=1200&hei=1200&fmt=jpeg&qlt=95&op_sharpen=0&resMode=bicub&op_usm=0.5,0.5,0, 0&iccEmbed=0&layer=comp
I just bought a new mac air too...I was gonna get a mbpro but they are just too expensive -- the one I configured was at around 3000$
Wanna know what's lame about using the thunderbolt display with the mac air? So the new mac air has the magsafe connector on one side and the thunderbolt connector on the other -- they're not on the same side like the macbook pro is (see picture) -- so basically the cable is going to have to slack around the back of the macbook air -- who designed that? Must have been smoking some good meth ;p

IMac or Macbook Pro w/ Thunderbolt Display?

I've decided to switch from PC to Mac.
I much prefer a desktop setup, so I originally decided to go with the iMac, but then I was checking out the Apple site & saw the Thunderbolt Display, which essentially lets you plug in your Macbook & use it as a desktop.
I'd be using it as a desktop for the most part, so most of the time the Macbook would just be sitting there plugged into the Thunderbolt Display. It's just nice to be able to pick it up & go also if I want to.
I'm not really sure of the differences in performance, space, etc. between the two, so does it make sense to do that if I'd be using it mostly as a desktop, or would I be better off just getting the iMac?

You are welcome, Will.
I have an iMac and MBP and eally am happy with both...run large FORTRAN codes on both with great success.
My daughter is the senior Art Director (graphic design degree) at an ad agency in NYC. She has the MBP at home with the high-res screen (15"), and a fully loaded 27" iMac in her office with a 30" Apple cinema display attached, almost 5' of display. Is very successful using both machines for heavy-duty graphics work. The larger iMac just means it is much easier having multiple applications open, multiple windows, side-by-side instead of using the maximize/minimize process. So, both are workable, but one is more convenient than the other.
Go to an Apple store or reseller and spend an afternoon with both machines you are interested in and get a goof feel for them and the image quality.
Good luck making a decision.

Thunderbolt display wakes up to horizontal shreds

After a few days of my new Thunderbolt display has a problem - running with my mid 2011 11" MacBook Air (Lion / 1.8GHz Core i7/ 256 GB) .
When the screen wakes up, it momentarily (3 secs) displays the screen in thin horizontal shreds. As if I ran the image through a paper shredder. Then it resolves to the correct image. Standard hook up to MBA with built in cords.
I've read about problems with flickering screen - anyone else know about this?

See if there is a way to turn off CEC on the Philips through its menu system and see if that helps.

Thunderbolt display and macbook pro calibration

I have a macbook pro mid 2011 and a thunderbolt display and they both have been calibrated by a Spyder device, I sometimes grade images on my laptop but when I get back to the office the shots look different, any ideas?t

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'.

HT2494 Thunderbolt display

I just connected my Thunderbolt-HDMI adapter and the computer screen will not display on the tv. The TV has a picture of some nice stars on it but the image that's on my monitor will not display. Do I have to go into some menu to activate the Thunderbolt display?

Hello Melissa2730,
It sounds as if things are currently set in an 'Extended desktop' arrangement, where the secondary display will provide additional workspace. The following article provides further information about using another display with your Mac.

Why is my 15" rMPB crashing when using 2 Thunderbolt Displays?

Over the last few days my 2012 15" rMBP has been crashing periodically.
Today it continued to crash every few minutes, I tried resetting PRAM and SMC - didn't seem to help. After reading somewhere (not here) people having issues with Multiple external Displays, I onlly plugged in one of my 2 Thunderbolt Displays and it seems to be stable.
In my normal set up I use 2 - 27" TBD's and a 55" Sanyo TV via HDMI - it has worked great for over a year but now I am experiencing continued crashing when I have everything plugged in.
Is this a known issue?
I think this may be an issue with the last update - which was installed on my rMBP on the 9th or Jan (only 9 days ago)... that is about when I first started noticing an issue.
Is there anything I can do?

Welcome to Apple Support Communities
Note that your MacBook Pro is using the dedicated GPU and you have got two GPUs. The dedicated GPU generates more heat, and even more if you are using the GPU to display image in three displays (including your built-in display). I would not be worried if fans are working correctly

What I want to see on the next thunderbolt display.

One of the problems with the current version of thunderbolt display is that it isn't aligned with the iMac. One great solution is if the height is adjustable, ii it`d be ergonomic (every table and chair is different) and align perfectly both on the bottom or top (assuming different screen sizes).
There is also no decent solution I could find to rotate screens 90 degrees so it facilitates writing and coding. The best solution in my opinion is to unlock rotation when the user rotates to the back, then when the user rotates to the front to be able to use the screen it would lock again and the OS would rotate the image automatically. The upside is that when the user rotates to the back to unlock rotating to the sides it would stop the screen from hitting the table and would be an elegant solution as it keeps the back of the screen with no unnecessary buttons.
If anyone knows a great screen with rotation, let me know that I want to buy it.

#1 new feature: Render Faster Button!
#2 new feature: Steampunk control surface! Real world cranks, dials and knobs! Fine Victorian gingerbread wood inlays. The sweet smell of burning coal.
But seriously, if you've been keeping track of when Adobe releases software, chances any new features would have to have been locked down by now so they can program it in and test it thoroughly.
So really, what would you like to see in CS8? But you can't answer that until CS7 comes out!

Macbook, Thunderbolt display, Bootcamp problem.

I have a Macbook Pro connected with Thunderbolt display. The Macbook has Bootcamp 5.5 and Windows 7 Prof 64-bit. When working in Windows the screen gets blank, but network and USB are still working. Sometime the screen of the Macbook goes blasnk also, not always. After that Macbook does not turn on when disconnecting the Thunderbolt display. This issue is also in OS X Mountain Lion.
2 weeks worked without any problems, but this started yesterday and today the issue was too time consuming.

If you read the tips in Boot Camp Assistant, you would know that only Windows 7 is supported with Lion.
The DVD if it was sold as physical media and your computer is listed as supported, but if you burned an ISO image and did not reduce burn speed to slowest, it will not be accepted or work (even if it appears to install).
BCA sets the default boot OS volume to the Windows FAT "BOOTCAMP" so that Wndows can restart multiple times to install and update on its own. YOU have to format to NTFS during install.
And you need to go to OS X control panel (system preferences) and use Startup Disk to make OS X the default again.
