Imac 27 inch with additional Apple Thunderbolt Display (27-inch)

Hi there,
Recently I bought a 27 inch iMac. I want to connect my Apple Thunderbolt Display (27-inch) as a second screen.
The iMac has 2 thunderbolt ports. Attaching the Thunderbolt Display has no effect, the screen keeps black.
If I attach my Macbook Air it directly shows a second screen for my Air (so the screen is fine).
How can I enable the second screen for my iMac ?
Love to here.
Walter

Try Command + F2
You should be able to make it work from there

  • Difference between a Apple LED Cinema Display (27" flat panel) and a Apple Thunderbolt Display (27-inch)?

    May i know the difference between a Apple LED Cinema Display (27" flat panel) and a Apple Thunderbolt Display (27-inch)? both products look the same to me, even the prices are the same, but the name of the product is different. Its so confusing! I want to purchase a secondary display for my 21" iMac, but idk the difference between the two.
    furthermore, another question i have is, is 27" the largest display i can get? is there larger ones (just the screen, not the computer)?
    please help, thanks!

    One has thunderbolt capabilities, the other doesn't.
    is 27" the largest display i can get? is there larger ones (just the screen, not the computer)?
    No you can get a larger one.  Maybe not an Apple one, but certainly another brand.

  • Newest Mac Pro: Displays  How will 4K be displayed?  : 4K 3840x2160 UHD 4096x2550  Where as: 27-inch Apple Thunderbolt Display=2660x1440

    How will 4K be displayed?  :
    4K 3840x2160
    UHD 4096x2550
    Where as:
    27-inch Apple Thunderbolt Display=2660x1440

    4k is the generic term for resolutions that have a horizontal number of pixels around 4000. The two most common resolutions are Ultra Hi-Def (UHD) and Cinema 4K (C4K). The first is 3840x2160 and is exactly four times the resolution of "Full HD", or 1080p. The second is 4096x2160 and is one of the "standard" resolutions used in digital cinema projection.
    The HDMI 1.4 standard supports both of these, but only at certain refresh rates. UHD, being the consumer version, is supported at 24Hz, 25Hz, and 30Hz; C4K is only defined for 24Hz since most of the material is going to be film-sourced. (This implies that 25/30Hz will include TV material at half their original rates of 50/60Hz.) Over HDMI, all four of these timing formats run at the same clock rate (297MHz, ignoring the fractional versions). This is the highest clock used in this version of HDMI, although the standard allows up to 340MHz. (There may be PC timing formats between 297-340...)
    Using generic terms, we call these modes "UHD30" to imply resolution and refresh rate, and if a TV supports UHD30 it will always support UHD24 (although it is not a rule, merely a reflection of reality). A TV can only support C4K24 in 1.4, but it doesn't have to. There are many TVs that will support UHD24 or UHD24-30, but not C4K at all. So the practical limit of HDMI 1.4 is "up to 4k30."
    HDMI 2.0, which the Mac Pro does not have [yet], provides dot clocks up to 600MHz (although above 340MHz, they are all divided by 4) and allows "up to 4k60" for pixel encodings of RGB444, YCC444, and YCC422. The new standard also allows 4k50/60 to use YCC420, which sacrifices some color information (known as 'uses chroma subsampling') but allows the data to be transferred at the same rate as 4k30. While "fine" for video--since it was probably delivered over BD/DVD or streaming at YCC420 to begin with--it is not fine for you computer's output.
    I just got a 4k TV because I was tired of my dual 1920x1200 DisplayPort monitors after coming from the original 30" Cinema display of 2560x1600. Specifically, I used to enjoy >1080 pixels tall. But here's the problem with the 4k TV: while it has HDMI 2.0 inputs, the MacPro has only HDMI 1.4 so the output is limited to "up to 4k30". Moving the mouse is laggy and not smooth as it would be if the display were 60Hz. Furthermore, the MacPro is not offering me a choice between UHD or C4K--both of which the TV supports--and is instead defaulting to the largest resolution of C4K. This means the refresh is only 24Hz. And that's why I'm in the forums today--to see if there's a way to get my output to be UHD, but at 30Hz.
    In a couple months, several companies will be selling DP-to-HDMI2 dongles that will support 4k60. So I am holding my breath until then.
    Now, to specifically and accurately answer your question: Out the current MacPro's HDMI 1.4 port, you will get the highest resolution your TV (called the Sink) will support. If your TV has C4K24, then that is what will show up. If your TV does NOT have that, but has UHD24-30, you SHOULD get UHD30. If your TV ONLY has UHD24, then that's what you will get. If you get a TV, the chances are really, really good that the panel will have 3840 pixels across and 2160 lines down. In this case, you want the Mac to output that resolution and put the TV into pixel-for-pixel mode so every input datum is mapped to a single display element. Since most displays overscan, the Full mode will expand the incoming data from 2-5% which can eliminated the crispness (and also cut off the extremes of the Desktop). Also, if you are outputting C4K (like I am) AND you have switched to P4P mode, the horizontal dimension is shrunk by 6.6%.
    If any of this is unclear, just reply. But I will say that this 40" TV is really useful, and once it is running at 60Hz...bellisima!

  • Apple thunderbolt display can work with a macbook pro 2009?

    Apple thunderbolt display can work with a macbook pro 2009 (mini display port? The image passes through the mini display port to the monitor, but the connections (Firewire, USB, ethernet) do not work. Can you confirm?

    I'd love to get confirmation if this is the case too.   I was all ready to buy the new iMac until I found I couldn't use it as an external monitor for my DisplayPort-based MacBook Pro.  And then I was all ready to buy the new display.
    I really hope Apple hasn't restricted this to purely Thunderbolt-equipped Macs. I know I'll end up upgrading my MacBook at some point but I can't do so just yet, and this means I'll have to go for some third-party display, camera, speakers etc for the new Mac Mini which is crazy.

  • There is no display on Apple Thunderbolt display, when Daisy chain connect with six LaCie Little Big Disks.

    Hi, Everyone,
    I have aquestion with Thunderbolt daisy chan.
    I have six LaCie Little Big Disks and Apple Thunderbolt Display to make daisy chan and I got a problem.
    I place the Apple Thunderbolt Display at the end of the chain, and six LaCie Little Big Disks infront, and Apple Thunderbolt Display does not show anything.
    If I plac the dell u2711 (DP1.1) Display at the end of the chain, and six LaCie Little Big Disks infront , dell u2711(DP1.1) displays.
    If I place the Apple Thunderbolt Display at the end of  the chain,and five LaCie Little Big Disks infront. Apple Thunderbolt Displays well.
    Is it because the hardware limitation that Thunderbolt daisy chan can only have maximum 6 Thunderbolt deivce?
    Apple Thunderbolt Display Should be DP1.2, why it doesn’t display?
    My workstation running Windows 7x64 or Windows8.1x64
    Thanks ,Myron

    if you reduce the number of disks to 5 and the display works, I think we'll have your answer.

  • Apple Cinema Display 24-inch sleep problems with MacBook 13-inch?

    Hey guys,
    Occasionally, my MacBook (13-inch, 2009) when connected to my Apple Cinema Display 24-inch screen will not wake up from sleep mode - whether in clamshell mode, or not. Even if i unplug the Display from the Macbook, the MacBook will not wake up.
    This can be very frustrating when it occurs because i have no choice but to give the MacBook a hard shut down.
    Not sure whether I'm the only one with this problem, but if there is any solution to this issue it'll be greatly appreciated.
    Cheers!

    You might try running the MacBook in Safe Mode for a while to see if the problem still occurs when running safe. If the problem goes away while in safe mode, that would point to a problem in the configuration of your main account.

  • Apple thunderbolt display - Can i work it with the new MacBook Pro's, which have a HDMI Output?

    I Bought my Apple thunderbolt display around 2 years ago now, tougther with my MacBook pro. I am thinking of switching my MacBook out tough with a new one this summer.
    But will the new 2013/2014 macbook's work with my thunderbolt display???
    /Nikolaj

    Yes.  The New Retina MacBook Pro has two Thunderbolt ports.  Plug the display into one of the Thunderbolt ports.
    You will need a MagSafe adapter.

  • Apple Cinema Display (20-inch DVI 2005) not working after 10.10.3 update

    I have an Apple Cinema Display (20-inch DVI 2005) that isn't working after installing the 10.10.3 update. The screen is just blank, and the power light just blinks a few times every 30 seconds or so. I use this as a second monitor with my iMac (27-inch, Late 2012). Any way to fix this? Thanks!

    Thank you for the update!
    Next I would recommend the Reset the System section of the following article for additional troubleshooting:
    Apple computers: Troubleshooting issues with video on internal or external displays
    Reset the system
    You can reset the Mac's parameter RAM and SMC. 
    Reset the resolution
    Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
    Start up in Safe Mode.
    From the Apple () menu, choose System Preferences.
    Choose Displays from the View menu to open the preferences pane.
    Select any resolution and refresh rate that your display supports.
    Restart your computer.
    I would reset the SMC and the PRAM together, in that order one more time, then do the Safe Boot if needed.

  • Macbook pro 17 inch primo 2011 and thunderbolt display crashes

    I have a Macbook pro 17 inch primo 2011 and thunderbolt display which has recently started to crash.
    Only modifications I have doen lately is I swapped the CD/DVD drive for a harddrive and put in 16 GB of ram
    but it has been running for more than a month with these hardware additions without problems.
    Today my Macbook has started to crash frequently within 10 min to 1 hour after plugging in my thunderbolt display.
    I tried to check CPU heat, change RAM but it keps crashing.
    When it crashes it either gives me a blue screen, a black screen or a distorts everythings and freeze up.
    When rebooting I have to press Command-Option-P-R to clear NVRAM / PRAM.
    I found a few support threads from people having similar problems so I started to disconnect the thunderbolt display
    and without plugging it in my laptop works fine.
    I have done a SMC reset also but that has not resolved my issue.
    Below is the crash report and if anybody has any suggestions what to do to resolve this please let me know
    My thunderbolt display was purchased in late 2011
    If this is not solveable what options do I have ?
    Thanks !

    The other day I got the blue screen, the fan going on high, and then when I disconnect my thunderbolt connection from my macbook pro - i get a shutdown.
    Today I got flickering followed by the fan on high and then again I disconneced my thunderbolt cable and after a minute or two a shudown.
    This never happened before.  Actually I was suprised to hear about a firmware update for flickering since that's never happened to me but since updating I now get the flicker.
    Any ideas??  Any help would be greatly appreciated as this is my work labtop.

  • 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.

  • Is it possible to connect a MacBook Pro (prev model 2009, 2.26ghz) to an Apple Thunderbolt display:  will the cable fit?

    Is it possible to connect a MacBook Pro (prev model 2009, 2.26ghz) to an Apple Thunderbolt display:  will the cable fit?

    Sorry it won't work.  It will fit but the laptop can't communicate with it.  Please see many of the other threads here, specifically this one just above your post, that is discussing this exact question.
    Apple's specs for the ThunderBolt display state that it needs a ThunderBolt-enabled computer.  Your laptop has a mini-display port connection so it is not compatible with the new displays.

  • Can Minidisplay Port work with the new Thunderbolt Display?

    I have a 2009 MBP 15 inch with Mindisplayport.
    Can Minidisplay Port work with the new Thunderbolt Display?
    If not, is there any adaptor i can use to make it work.
    I also have the new MBA with thunderbolt socket.
    Cannot decide which display to get.
    Thanks.

    Here's a new article that basically covers and clears up all the new Thunderbolt display questions (same things I previously stated).

  • W540 and 2 apple thunderbolt displays

    Hi
    I have just brought a W540 with windows 8.
    I am trying to connect two apple thunderbolt displays (daisy-chain) to the thunderbolt port on the W540.
    The W540 can only detect one of the displays – anyone who knows how I can get both displays to work ?
    In advance thank you

    I'm not really familiar with the Thunderbolt implementation on the W540, so someone else will have to pitch in.
    Does the display work properly with any other machines?

  • Windows 7 and Apple Thunderbolt Display

    I'm having difficulties getting the 27" Apple Thunderbolt to work reliably with my 13.3 MPPr using Win7 and Bootcamp. All the Bootcamp drivers are the latest, and the display works just fine using OSX 10.8.  When booting into Win7, the external display is dark, but audio, USB, and ethernet seem to work just fine..just no video.  Has anyone found a work around for this..  It's getting really frustrating.

    Thunderbolt problems with Windows 8
    TIP: Fix for Thunderbolt problem with Windows 8 in Boot Camp
    Boot Camp users who updated Windows 7 to Windows 8 may find that a Mac booted with Windows 8 does not recognize Thunderbolt . According to a new Apple tech article, the problem is an incompatibility with the Windows 8 Fast Boot feature (also called Fast Startup). The workaround is to disable Fast Boot using the Windows Control Panel.
    Here's how:
    In Windows 8, open the Control Panel. (You can move the mouse to the upper-right corner to activate the Charms bar, click the Settings icon, and then select Control Panel.) 
    Select Hardware and Sound. 
    Under Power Options, choose Change What the Power Buttons Do. 
    Under Shutdown Settings, uncheck the Turn On Fast Startup. Checkbox. 
    Click Save and then restart the Mac back into Windows.
    After restart, Windows 8 will recognize Thunderbolt devices attached to the Mac.

  • Mac Mini + 3x Apple Thunderbolt Displays?

    Can you connect 3 Apple Thunderbolt displays with a single Mac mini?

    Or for example can I use 2 apple thunderbolt displays + 1 HDMI display (for total 3)?
    Yes for the mid 2011 Mac Mini with AMD graphics.  See footnote 3:
    "Mac mini with AMD graphics can support an HDMI compatible device on its HDMI port when using two Thunderbolt displays."
    Or use something like USB to display adaptors in order to have 3 displays total?
    Yes, but with resolution and performance limitations.
    <http://eshop.macsales.com/item/Newer%20Technology/VIDU2DVIA/>
    My ultimate objective is for 3 displays (e.g. 3 apple thunderbolt displays).
    Would appreciate any assistance / recommendations on the best way to achieve this.
    There is one Mac that can handle more than two Thunderbolt displays.
