    What solutions are you aware of that lets a macpro 2008 (3,1) output via HDMI with audio? Unfortunately with this model, getting a graphics card that has a HDMI or mini display port to HDMI can not carry audio.

    At the moment I connect my macpro to an HDTV from the DVI with a DVI to HDMI adaptor and the audio output to the amplifier. It'd be nice to just change the HDMI input on my tv to switch to my mac pro, rather than having to change the input on the tv AND amplifier.

    I know some HDMI solutions can be laggy, like using USB2 > HDMI. I'm looking for something with no delay. I'd be outputting with DVI and either the audio output or optical audio output.

    I did some searching and came up with the following.

    I have no experience with the above. What are you thoughts on the above products? What can you recommend that has no delay?

    Thanks for your time

    I also found


    "I should of listened to the first reviewer with a MacBook Pro. It also doesn't work at all on my intel Mac Mini connected to my HD TV. In the directions I read that it will not work on non compliant HDCP products. Well, ALL Macs are non compliant HDCP. So if you own any Apple Computer DON"T PURCHASE THIS DEVICE!!!"
    This is why I'm looking for macpro users who can share a device that works with 1080p and no delay

    DVI does not carry audio, hence the expensive adapters.

    Displayport, however, can carry audio. I know that my Mac Pro 5,1 with ATI 5770 and a simple mDP -> HDMI cable works with audio on an HDTV. However Apple does not support thus in machines that were released before 2010. There may be a hack ?

    So your tv doesn't have an audio input that works with the HDMI input?

    There are lots of solutions out there...



    Mini Displayport:

    Agree with above posts. You need an Apple-approved video card with an HDMI or Display port (then buy an HDMI adapter). This limits you to the 5770 and 5870. It should at that point "just work".

    Also, keep in mind older mac pros (as with older PCs) can't do audio over HDMI. I am not sure the 3,1 is one of those.

    MP 3,1 cannot be made to output sound over HDMI or MDP using OSX. These are indeed the adapters you need, just pick the right one for your outputs:

    Thanks for your help paulrbeers


    Is the best solution for me. Many reviews of it working well with macs in 1080p.

    Update1: I've ordered this, an optical cable, a dvi cable and a HDMI cable. I'm hoping this will work well as a dual screen setup to. I'll keep everyone posted.

    Update2: Works perfectly

    Note: This is an ideal solution for people with macpro 1,1 2,1 and 3,1
