Hi Dirk Michael,
Welcome to Apple Support Communities.
It sounds like there is an issue with the image quality on a Cinema Display connected to your iMac. Try calibrating your display as shown in the first article below, also use the second article to verify you're using a compatible video adapter.

  • Trouble with 30" HD Cinema Display using Mini DisplayPort to DVI Adapter

    I bought a new MacBook Pro and I am having trouble getting the full resolution to work with my 30" HD Cinema Display (purchased in 2007 max resolution 2560 x 1600) using a Mini DisplayPort to DVI Adapter.
    According to the specs page, http://support.apple.com/kb/SP581 , the max resolution of the HD external display is supported. Unfortunately the max that I can set it to is: 1280 x 800
    Has anyone else had the same issue?
    If this isn't resolved I'm likely going to exchange my MacBook Pro for one that can support this display.

    So I went and bought the Mini DisplayPort To Dual-Link DVI Adapter as suggested and it seems to work great.
    Now the problem that I have is when I open up Apple's DVD player, the screen is blank but I can still hear audio.
    If I unplug the display, the movie will display properly. Rebooting with the display plugged in doesn't help either. I also deleted all the DVD players enc setting files so that they would re-initialize but no luck.
    Any idea what this problem might be??

    im running OSX 10.7.4

    Hi There,
    I have had the exact same issue but with a projector.
    The issue lies with Mountian Lion 10.8.2.
    I tried many a combination with no luck to get HDMI working.
    Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
    Bought my macbook home and voila, now displaying through my projector.
    There is a small graphics update after 10.8.1 which seems to be the cause.
    Hope this helps.
    Thanks.

  • 27: iMac Apple Mini DisplayPort to DVI adapter quits working post-firmware

    I iMac Apple Mini DisplayPort to DVI adapter suddenly quit working after I installed Apple's latest iMac display firmware update. This is an Intel Core i5; the monitor is an LG Flatron 24" Wide, and when it powers up it says "no video input" and goes into power-saving mode. No amount of replugging cables helps, but the monitor works fine on other computers.
    The Displays control panel just shows one monitor, and clicking Detect Displays does nothing.
    I suspect Apple's Display Firmware Update. My installer log shows the following, but the problem only happened today after the latest update:
    6/1/10 9:45 AM 27-inch iMac EFI Firmware Update 1.0
    6/1/10 9:45 AM 27-inch iMac Display Update 1.0
    6/4/10 11:47 AM 27-inch iMac SMC Firmware Update 1.0
    6/4/10 11:47 AM 27-inch iMac Display Update 1.0
    6/5/10 7:29 AM 27-inch iMac Display Update 1.0
    I have automatic updates disabled, but after each update I would see more firmware updates ready, but caution leads me to never install more than one of these at a time, and then to wait a while to see if anything bad happens. The odd thing is that the Display Update 1.0 seems to have been installed three times in this course of events. Alas, there appears to be no way to uninstall a firmware update.
    Here is the System Profiler Graphics/Displays output:
    Chipset Model: ATI Radeon HD 4850
    Type: GPU
    Bus: PCIe
    PCIe Lane Width: x16
    VRAM (Total): 512 MB
    Vendor: ATI (0x1002)

    Online: Yes
    Built-In: Yes
    Connection Type: DisplayPort
    Display Connector:
    Status: No Display Connected
    It says the Mac sees no display connected, and the display gets no video signal. Since the adapter is an active device (it has powered electronics to convert DisplayPort signals to DVI signals) I suppose it could have just coincidentally died. But that seems unlikely given that the thing worked perfectly just before the last firmware update.
    Does anybody have similar experience, or better yet, a fix?

    Unfortunately the Apple Knowledge Base does not give much information about this update. Such has how to tell if it has been successfully installed. I suspect that because it keeps recurring in the install log that it has not been installed successfully as yet. Are you receiving this update through Software Update? Can you locate the installer for this update? It maybe located in Apps/Utilities.
    Some firmware update installations can be interrupted/corrupted by attached devices. If you find the update's installer on your iMac, I suggest that you detach all external devices from the iMac, use an Apple USB keyboard & mouse if available, follow the instructions carefully and install the update manually. If you do not locate the installer I suggest downloading manually from the link below and installing it.
    The Knowledge Base article mentions that your iMac should also have a Graphics Firmware Update. I suggest that you download and install that as well.

  • Use Mini DisplayPort to DVI adapter to connect Mac Mini to Cinema Display?

    Hi
    I have a new-to-me current model Mac Mini and want to use it with my 20" Cinema Display (model A1081).
    The Mac Mini instructions say to use the HDMI port on the Mac Mini with a DVI>HDMI adapter cable. I seem to have only a DVI>Mini DisplayPort adapter cable. I'm guessing this will be OK to use, but don't want to fry the system straight out the box
    Can anyone confirm it's OK to use DVI>Mini DisplayPort connection to drive the display?
    TIA
    Jim

    Thanks for the reassurance BSteely!
    One thing I've seen when rummaging through the forum is a suggestion that with MDP>DVI adapter is problems with display waking from sleep. Short of setting it not to sleep, is there a workaround to wake it up again if it doesn't respond to usual stimuli?
    TIA
    Jim

  • New iMac 2012 & Mini DisplayPort to DVI-Adapter

    Will this adapter work with the new iMac 2012 (27-inch)?
    (I´m not sure because there are only thunderbolt ports on the picture and no Mini DisplayPort)
    Thank you!
    bye

    Hello,
    A notable peculiarity of Thunderbolt is that it uses exactly the same connector as Mini Display Port, and that's not all. The Thunderbolt connector also carries Mini Display Port video signals. That means you can plug a Mini Display Port video cable/adapter in to a Thunderbolt connector and your monitor will work.
    If you plan to do other things with your Thunderbolt connector and don't want it wasted on a monitor, you can also choose an HDMI --> DVI adapter, which for your purposes will be functionally equivalent.
    You can even use both at the same time.

  • Mini DisplayPort to DVI + DVI to VGA Display Adapter, will it work?

    Hi,
    I have a MBP, and I have just purchased an apple Mini DisplayPort to DVI adapter.
    I want to connect it to a VGA port.
    Can I buy an Apple DVI to VGA Display Adapter and connect it to the connector above.
    Will that work? Any one with experience who could advise me on that?
    Thanks.

    This does not work, because the Mini DisplayPort to DVI adapter has a DVI-D port that transmits only digital signals. VGA uses analog signals.

  • Mini DisplayPort to HDMI Adapter by Belkin for iMac 2009 failed to work

    This is an SOS message. I have purchased another Mini DisplayPort to HDMI Adapter and I have iMac (27-inc, Late 2009) running OS X Yosemite (Version 10.10.1).  I have carried out the connection of Mini DisplayPort to HDMI adapter to LG Plasma TV Screen, but there is no sign of any of the equipment reading or aware of the connection.  Is there anybody out there who can help me make it work?  Also, why is that Yosemite - System Preference, click on Displays does not contain - Arrangement?  I'll greatly appreciate any useful tips from the community or apple support team.

    Eric has helped in providing in dept understanding around the subject matter, but unfortunately, it has not provided the solution to the problem.
    The Mini DisplayPort to HDMI Adapter when connected to the external Plasma TV screen, nothing happens.  The System Preferences was accessed -and the Displays monitor sign was clicked, but it only showed - Display/Colour, which according to the instructions / descriptions contain in the - Video Troubleshooting Internal and External Monitors literatures and video, there seems to be missing - Arrangement / or AirPlay from my OS X Yosemite version. 
    The above is the version of OS X Yosemite - showing on my *iMac when clicked on System Preferences, and as result I have not been able to make the Mini DisplayPort to HDMI Adapter to LG Plasma TV Screen to work.
    My *iMac is -
    iMac (27-inch, Late 2009)
    iMac10,1
    (10.10.1)
    MB952XX/A
    Running OS X Yosemite
    When the above image is compared with the following image below, there is definitely something missing and it’s probably affecting the Mini DisplayPort to HDMI Adapter to work in my connection.
    Questions:
    How can I make my iMac 10,1 (27-in, late 2009, currently running OS X Yosemite 10.10.1) to have the above AirPlay mirroring or Arrangement to activate the connection? 
    Are there other ways I can make the connection to work?
    Is there any body who has a similar iMac specs and OS X Yosemite who has overcome connecting to external Plasma TV Screen?

  • My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter.

    My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter. I also tried the HDMI to DVI adapter ane the Mac-Mini with same result. The monitor does work on my older Macbook Pro that has the DVI connector. Is it a Software/Driver issue ?

    Should be extremely simple, please carefully read Connect multiple displays to your Mac. If you still have problems then it's probably a cable issue that would be resolved by replacing the adapter cable. You should be using this adapter. If you are using a third party adapter that might be your problem!

  • Thunderbolt display: devices not discovered after using Mini DisplayPort–to–VGA adapter

    I have an interested problem related to using my MacBook Air in clamshell (closed) mode, connected to a Thunderbolt display. The problem appears to be related to moving my MacBook air between my office and my home.
    At the office, I use the MacBook Air with an external VGA display, connected via the Mini DisplayPort–to–VGA adapter. At home, I use the MacBook Air together with a Thunderbolt display. An Apple USB keyboard is also connected to the display.
    Mini DisplayPort–to–VGA adapter implicated
    The following sequence of events causes the problem to occur:
    Use the MacBook air (open) together with a VGA display, connected via a Mini DisplayPort–to–VGA adapter (depicted at right);
    Put the MacBook Air to sleep by closing the lid, and disconnect the Mini DisplayPort–to–VGA adapter (I am not sure if the order of these two steps is significant—I usually perform them almost simultaneously when packing up my MacBook Air and getting ready to leave the office); and
    With the MacBook Air still closed, connect it to a Thunderbolt display with a connected USB keyboard.
    At this point, I would expect to be able to wake up the MacBook Air by tapping on the space bar of the keyboard. However, what I have observed is that this does not wake the MacBook Air.
    I can wake the MacBook however by moving or clicking a Bluetooth mouse that is paired with the MacBook Air.
    At this point, although the MacBook Air is awake, and the display is working, the USB keyboard connected to the display still does not work. This is the problem, in a nutshell.
    Unplugging the USB keyboard from the display, and plugging it back in causes the MacBook Air properly to identify the keyboard.
    I used Apple System Profiler to save a list of identified devices at two points in time:
    Immediately after waking the MacBook Air by moving the Bluetooth mouse (at which point the USB keyboard was not working); and
    After unplugging and plugging in again the USB keyboard (at which point the USB keyboard worked fine).
    Many devices are enumerated in the second list that are missing from the first. For example:
    Keyboard [email protected]  <class IOUSBHubDevice, id 0x1000378ef, !registered, !matched, inactive, busy 3 (37993 ms), retain 6>
    AppleUSBHub  <class AppleUSBHub, id 0x1000378f2, !registered, !matched, inactive, busy 1 (37987 ms), retain 6>
    [email protected]  <class IOUSBInterface, id 0x1000378f4, !registered, !matched, inactive, busy 1 (37986 ms), retain 6>
    Keyboard [email protected]  <class IOUSBHubDevice, id 0x1000378f6, registered, matched, active, busy 0 (7 ms), retain 10>
    AppleUSBHub  <class AppleUSBHub, id 0x1000378f9, registered, matched, active, busy 0 (1 ms), retain 9>
    [email protected]  <class IOUSBInterface, id 0x1000378fb, !registered, !matched, active, busy 0, retain 7>
    Apple [email protected]  <class IOUSBDevice, id 0x1000378fd, registered, matched, active, busy 0 (112 ms), retain 11>
    and many child devices…
    Using the Mini DisplayPort–to–VGA adapter appears to be a necessary step to causing this problem to occur. If I merely disconnect the MacBook Air from the display, let it go to sleep, and then reconnect it again, the USB keyboard will work immediately and can be used to wake the computer from sleep.
    Some devices are discovered even when the computer is in sleep mode. This is how it should work.
    The problem appears to be that when a Mini DisplayPort–to–VGA adapter has been used since the last time the computer was connected to a Thunderbolt display, the MacBook air does not discover devices completely when it is again connected to the Thunderbolt display while in sleep mode.
    Can anyone else reproduce this problem?

    Hi glraczon.support,
    It sounds like the external display you are using (projector) operates at a smaller resolution than your MacBook Pro. You may want to configure the display preferences in System Preferences for the external projector.
    Here is an article that may help you with that process:

  • Mini DisplayPort to VGA Adapter NOT DISPLAYING ON EXTERNAL SCREEN

    Hello!
    Mid 2012 MacBook Pro
    Processor  2.9 GHz Intel Core i7
    Memory  8 GB 1600 MHz DDR3
    Graphics  Intel HD Graphics 4000
    Software  OS X 10.9.3 (13D65)
    I have a mid 2012 MacBook Pro, I have connected a Mini DisplayPort to VGA Adapter in order to watch movies on a HP w19e LCD display.
    Ive been using this adapter for a year now and I have never had any problems with it, until now...whenever I connect it to my mac's display turns black, and nothing happens, so I wait and the LCD display shows the unfurtunate NO SIGNAL message, so I wait a little longer and still nothing happens, I unplug the Mini DisplayPort and plug it back in, and nothing happens, and when I say nothing happens I mean nothing happens, my mac's display is black as if it was in sleep mode, I get no signal on the HP LCD and I can't get my computer's display to show image again, the only way to do it is to force restart it.
    I looked up the problem and I found a forum with a possible solution for it and did as it said.
    1) Restart the computer in Safe Mode with display attached (shut down and restart while holding down shift key).
         The display showed up without distortion.
    2) Change the display to my desired preferences (dimensions and refresh rate).
    3) Restart computer. ...and it works like a charm.
    I followed the directions and it worked... but after I restar to go back to um.. normal mode, the problem is back.
    Please I need my LCD screen how can I fix this.
    I hope I didn't confuse anyone, sorry for my english

    I'm having the same problem. When I try to connect to the switch in our conference room (connecting both a flat panel display and/or a projector, both with much higher native resolutions), all I get is 640x480. This is a huge problem to using bootcamp, and I really need to get this to work. I was able to get a higher resolution 1280x800 on a separate, portable display, so I'm wondering if people have the problem with standalone projectors or only with projectors connected to some sort of switch, in my case an Extron MPX423A. I have also tried this in both Windows Vista (32-bit) and Windows 7 RC1 (32-bit), with the bootcamp drivers and the latest NVidia drivers, and the behavior is the same all around.
