Q: Mirror wont work

I have an iMac 24-inch Mid 2007

 

Processor  2.4 GHz Intel Core 2 Duo

Memory  3 GB 667 MHz DDR2 SDRAM

Graphics  ATI Radeon HD 2600 Pro 256 MB

Software  OS X 10.9.4 (13E28)

 

I am trying to mirror the screen on my Samsung HDTV.  I have made all the appropriate hardware connections (HDMI wire, adapter etc).  When I try to mirror, the response i get is

 

"The Arrangement tab of Displays preferences is hidden because you only have a single display attached to this computer."

 

Is my iMac too old and therefore not able to mirror onto a tv?  Any solution will be welcomed!

 

Thank you!!!

    Hey there Alersjr,

     

    It sounds like you are unable to see this TV on your Mac to configure the display preferences for it when connected by HDMI. You should use these troubleshooting steps from the following article:

     

    Apple computers: Troubleshooting issues with video on internal or external displays

    http://support.apple.com/kb/HT1573

    No video or no signal, image distortion, "snow," or flickering

    Check connections

    When using an external display be sure to check the following:

    1. If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
    2. Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
    3. Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
    4. Try unplugging the video adapter or cable and then plug it back in.
    5. If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
      • Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
    6. If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).

    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:

    1. Start up in Safe Mode.
    2. From the Apple () menu, choose System Preferences.
    3. Choose Displays from the View menu to open the preferences pane.
    4. Select any resolution and refresh rate that your display supports.
    5. Restart your computer.

     

    Thank you for using Apple Support Communities.

    Regards,

    Sterling

    Hi Sterling R-- What I am trying to do is to see my computer screen on my TV... not the other way around. My big concern is that because my iMAC is a mid 2007 model, that its not programmed to mirror... any suggestions?
