    I have an early '09 Mac Mini. It has Mini DVI and Mini DisplayPort, and it supports dual displays. I am trying to play content on my 32" 1080p TV and 24" 1080p TV at the same time. Right now I can only play content on one TV at a time, even with mirroring on.

    I have
    Mini DVI out to Mini DVI/DVI Adapter to DVI/HDMI (3') to AV Receiver to HDMI (6') to 32" TV
    Mini DisplayPort out to Mini DisplayPort/HDMI Adapter to HDMI (25') to 24" TV

    What is the most affordable way to get both TVs to display the Mac Mini content (Plex, movies, music, etc.)?

    Mirroring is supposed to put the same display on both monitors. Are you saying that it doesn't? Or is it just not how you want it?

    It's not displaying at the same time. it only shows on one monitor at a time.

    It sounds like something is broke. When you go into System Preferences - Display - Arrangement and select Mirror Displays, what happens? OSX should find the least common denominator resolution and show the identical picture on both displays.

    I just tried again on my 2009 with two monitors (miniDP->VGA and mini-DIV->DVI-D) and mirroring with VLC and EyeTV works full screen video.

    Re-cycling this thread to ask a more general question...

    Since it's always dangerous to read more into specs than they actually say, I wonder if anyone has any actual experience of this?

    The description of the Graphics for the latest Mini includes the following:

    • DVI output using HDMI to DVI Adapter (included)
    • VGA output using Mini DisplayPort to VGA Adapter (sold separately)
    • Support for extended desktop and video mirroring across both ports

    Notice that it does not say anything about supporting DVI output using a Mini DisplayPort to DVI Adapter (sold separately).

    I wonder if this is possible -- to have an extended desktop with one monitor connected using the HDMI to DVI adapter and the second monitor connected using Mini DisplayPort to DVI?

    I don't have one to try it out myself, but I would imagine it would work. I can't think of any reason why it wouldn't.

    I have a 2009 Mac Mini. I have successfully had two monitors hang off it using MDP->DVI and mDVI->DVI (I would suspect with a '10 Mini the HDMI->DVI would work too). The only problem I have had with my Mini was doing MDP->HDMI and geting 1920x1200, but I think that was due to the third-party adapter I was using at the time.
