Play sound in Target Display Mode

I would like to play sound from my custom PC to my mid 2010 iMac 27", I have display through a mini display port cable, connected to my graphics card. (XFX Radeon 6870)
I have installed AMD Catalyst, which is giving me the option to select sound output through my graphics card, and therefore 'should' work, it obviously does not, does anyone know how to do this?

I think   you have a mis understanding of what TDM is, please carefully read Target Display Mode: Frequently Asked Questions (FAQ) - Apple Support

  • No sound on iMac in target display mode

    I've got a late 2009 27" iMac running Yosemite.
    When I connect either my MBP (Yosemite, late 2011 15") or my wife's rMBP (Mavericks, 2012 15") to the iMac using a mini Display Port cable and switch the iMac to target display mode using Cmd-F2, sound no longer works.
    Previously, when the iMac was running Mavericks, the laptops would route sound to the iMac via HDMI audio (I think) on the mDP cable and sound would be output via the iMac speakers or headphones attached to the iMac. Since upgrading the iMac to Yosemite, sound no longer plays.
    This occurs regardless of the laptop OS, Mavericks or Yosemite. The sound icon on the laptop get greyed out and shows that it is going to the "Color LCD" but no sound is output via the iMac.
    Any thoughts?
    Thanks

    Humm... I might go TosLink between the iMac and the FastTrack and then run the USB connection to the MacBook Pro when your using it in Target Display Mode.
    Or vise Versa, leave the USB connected to the iMac and use the TosLink connection for the MacBook Pro.

  • Disable sound on imac in target display mode

    Have a question about disabling the sound.
    I have a MacBook Pro connected to my iMac by the thunderbolt cable. I enable the target display mode on iMac with a script for disabling some configurations on iMac ( including the bluetooth for mouse and keyboard steal ).
    I set the sound output in the MacBook Pro to the iMac DisplayPort.
    The problem is now i have both outputs on iMac speakers. i want to disable all sound from iMac but keep the output from MacBook Pro on iMac speakers.
    Is this posible?
    Thanks.

  • Audio on iMac in target display mode.

    Here's my problem:
    I have a macbook pro with retina display that is hooked up to an imac via thunderbolt. The imac is in target display mode so that I can use it as a second monitor. I have some external speakers attached to the imac which I use when I'm using the imac by itself. I'm trying to make it so that I can use these speakers when in target display mode.
    When in system preferences I can set the sound output to the imac but the audio plays through the internal speakers instead of the external. Anyone know a way to make this work?
    Thanks in advance!

  • How can I use my 27" iMac (2010) as an additional display to my Windows 7 PC (target display mode)?

    So I have purchased a windows machines so that I can play all my favourite games on, and it's not so much a problem rather I have a 27" iMac that I would like to use as an additional monitor for said games.
    I have had a look at this article on using the iMac as a display for another computer and things looked promising. I think I need a bit of help getting there though as I can't find definitively anything online to tell me exactly what I need. Most stuff talks about connecting other Apple computers that have mini display ports.
    My PC's video card is an nVidia Geforce GTX 650 Ti that sports 2 DVI ports and a mini HDMI port (adaptor to full HDMI was included). The iMac has a mini display port. I went out and got a HDMI cable and Moshi Mini DisplayPort to HDMI Adapter (with audio) to try to use the iMac as the additional display. I connected the PC with [a generic] HDMI cable to the adaptor which ran to the iMac and went through the appropriate steps (ie. pressing CMD + F2) to initiate target display mode. Nothing happened.
    I have read that other people with different situations tried an SMC reset, but this didn't work for me either.
    At this stage I wanted to see if the DVI port would do anything, or perhaps looking at a particular kind of HDMI cable, but wanted to see what the community can offer up as advice.
    Any assistance would be greatly appreciated.
    Thank you.

    - DisplayPort cable, Adapter to Mini DisplayPort
    - iMac (Intel, 27-inch, Mid 2011) as 2nd screen, connected via Mini DisplayPort Adapter, Mavericks OSX 10.9.1
    Problem:
    - iMac does not start Target Display Mode

    - Lenovo via DisplayPort cable to 2nd screen works fine
    - Can switch between PC only, Duplicate, Extend display
    Question:
    - What is wrong?
    - What can be done to idenify the root cause?
    Kind regards, Marcel.

    Hello Marcel,
    It sounds like you are wanting to use the iMac in Target Display mode with your PC. Target Display mode is a feature that is supported from one Mac to another Mac according to this article:
    OS X Mavericks: Use another Mac as a display
    http://support.apple.com/kb/PH14264
    Target Display Mode lets you use a Mac as the external display for another, “primary” Mac.
    Thank you for using Apple Support Communities.
    Cheers,
    Sterling

  • HT3924 any HDMI converters available for iMac target display mode yet?

    Just got this bed with a pop-out TV, and I'm thinking about getting an iMac 27" to use instead of a TV. Problem is, I'll also want to attach an Apple TV or Freeview box to my iMac - so I can play content from my iPad / watch live TV from the freeview box. This would be technically possible with target display mode, except the Apple TV / Freeview box don't have mini display port output.
    Anyone know if there are HDMI to mini display port adapters available yet to facilitate this? From what I've read most of them only output from mini display port to hdmi, not the other way round.

    I have a Asus HD6570 2GB Graphics Card in that computer with HDMI out, DVI out, and VGA out. I have a Asus HD6570 2GB Graphics Card in that computer with HDMI out, DVI out, and VGA out.
    None of those will work.
    It has to have a Mini DisplayPort, not evn a Display port will work.

  • Brightness iMac in target display mode: who has it working in 10.6.8?

    "With Target Display mode, you can use your iMac (27-inch, Mid 2010) or  iMac (27-inch, Late 2009) with Mac OS X as an external display.": http://support.apple.com/kb/ht3924 . "Use the keyboard of the 27-inch iMac to adjust display brightness and sound volume and to control media playback of applications running on the 27-inch iMac in Target Display mode."
    This used to work perfectly for me. But under 10.6.8, the brightness control stopped working. Sound and media control still work as expected. I posted before on this.
    Now I know more people are experiencing this problem... I am looking for people who DO have it working under 10.6.8!
    I'm looking for anything I can do to get it to work, maybe the info from people who have it working gives me some clues.
    Lion is just around the corner. Please let me know if Lion fixes this problem for you.
    Thanks!
    Maarten

    I'm using two 27" imacs  and one of them is still on 10.6.8 one has been upgraded to Lion just now.
    I thought it was the Lion update which caused this issue for me because I installed  10.6.8 on both of them today as well.
    Now I can't adjust the brightness in target display mode on either  27" imac.... worse that that it sets it to full brightness too.
    I don't know of I want to try to go back to before 10.6.8 with time machine,  talk about gutted ?
    can you use monitor calibration as a work around ?
    I found TS3919 but it doesn't work BTW , it says to set the brigthness before entering target display mode..

  • After target display mode, iPhoto reports an error, "The current screen resolution is not optimal for iPhoto."

    I have the 27-inch (late 2009) iMac with mini-Display port input. Whenever I return from Target Display Mode, I get the attached error message and iPhoto becomes unresponsive (the window is still active, but clicking on it produces the error/warning system sound), I have to Force Quit it. The current screen resolution is not optimal for iPhoto (sometimes the error message is a little off the screen in the lower left and only the top of the window can be seen. This also seems to affect iTunes at the same time (by resizing the window to be super small), but without the error message or unresponsiveness.
    Has anyone else gotten this problem, and or might know of a fix?

    Yes, I have the same problem.  I have checked the resolution in Sysyem Preferences - display and it is properly set to the highest resolution (which is recommended).  I have no idea why this is ocurring but it is annoying.

    How do I connect a DVD play to iMac through "monidisplayport to HDMI" adopter?

    hello;
    i am finding that even Apple employees do not know the correct answers.
    i purchased a new 27 inch iMac last night at MainPlace in Naperville, Illinois.
    Two Apple sales associates told me that it would work with the mac mini which
    i purchased less than a month ago or with the macbook pro 13in. i knew it would
    not work with any of the three macbook pro 17inch.
    after much testing it is apparent that the "Target Display Mode" will only work
    if both computers have Thunderbolt/Mini DIsplayPort technology. It will not work
    with the current shipping mac mini.
    Apple really needs to clue in the retail store sales associates and rename these
    Thunderbolt/Mini DIsplayPorts something different since they will not work with
    the plain vanilla Mini DisplayPorts.
    I am debating about returning the 27 inch iMac based on this gross error on the
    Apple Sales Associates part.

  • Apple Mini DVI to DVI Adapter to connect Win7 tower to iMac / Target Display Mode

    I currently run Windows on bootcamp on the iMac (Mid-2011), although the tasks I perform (3D modelling, rendering and such) cause the Mac to get very hot, and as a result hae a slight burn mark on the LED LCD screen.
    I am buying a Windows machine, and am to uninstall bootcamp and use the Mac purely for OSX, but use the iMac screen as a monitor for the tower using Target Display Mode. My issue is - the Windows 7 tower only has DVI output. And as I understand, the Mid-2011 iMac only supports Target Display Mode via a thunderbolt cable.
    My question is - Will the Apple Mini DVI to DVI adapter allow me to connect the DVI-only tower to the iMac? Thanks in advance x

    Oh, I should mention also that the iMac is the 27" model. Mid-2011 3.4Ghz Intel Core i7 with 4GB RAM and 1TB Harddrive. And ATI HD5450 1GB Graphics.

  • Can windows 8.1 in boot Camp display in target display mode on an IMac?

    I have given up on Windows 7 running in Boot Camp on my 15" MacBook Pro and displaying it on my 27" IMac via thunderbolt and Target Display Mode. 
    The FAQ concerning Target Dsiplay Mode farily clearly says Windows 7 won't work. 
    But it  does not say Windows 8.1 will or will not drive Target Display Mode via thunderbolt.
    see:  http://support.apple.com/kb/HT5219, question 29
    Has anyone found that running Windows 8.1 in BootCamp on a MacBook Pro Retina mid 2012 will display via a thunderbolt cable in to Target Display Mode on a late 2013 IMac 27"? 
    I don't want to go to the trouble of installing Windows 8.1 and trashing my otherwise functional Windows 7 Boot Camp installation unless it is going to display properly on my late 2013 27" IMac running OSX 10.9.3 via thunderbolt.
    Thanks in advance!

    no, tdm doesn't work under bootcamp regardless of which windows is being used, imho i don't think it will ever work under bootcamp

  • IMac 27" Target DIsplay Mode + Answer to Windows 7 Boot Camp Install

    First, I'd like to address the handful of complaints I've come across about installing Windows 7 via Boot Camp on the new 27"iMac.
    The issue of the screen going blank when almost done has an easy albeit annoying answer. Simply connect the iMac to an external display, I used a small vga lcd with the Mini DisplayPort to VGA adapter. When the iMac's screen goes black the external lcd will continue, and when Windows 7 starts up it will download the updated ATI drivers. From there alls well.
    Second, my problem.
    Target Display Mode is a great feature. It worked great when I first used it, and it works great now except for the fact that the Command+F2 button combination stopped working. I have to manually unplug my MacBook Pro in order to get my iMac's original screen up. At first Command+F2 would allow me to switch back and forth, and now it does nothing.
    Any suggestions?

    Well, the usual first things to try for a display-related issue are
    Reset PRAM
    http://support.apple.com/kb/HT1379
    and of that does not help, reset SMC
    http://support.apple.com/kb/HT1543
    which is basically unplugging the iMac from power and reconnecting it following the precise procedure.
    Note: After resetting PRAM, you should go to System Preferences +Startup Disk+ pane to make sure your internal drive is selected (highlighted) as the startup disk.

  • Target Display Mode - Connecting pre-Thunderbolt Macbook Air to Thunderbolt iMac.

    I want to use Target Display Mode in order to display my late-2010 Macbook Air (pre-Thunderbolt) to a Thunderbolt-based iMac. Is there an adapter solution to connect, say, a mini display port + USB port on the MB Air to the iMac Thunderbolt port, such that TDM would work?

    Depends upon the situation.  Take a look at this blog:
