    Hi all,
    I've just upgraded to a 5770 in my old MP (2,1) - on the assumption that I could use all 3 monitor ports without problem. Not so!
    I acquired 2 mini display to dvi adapters thinking they would do but after trying them only 2 monitors work with all 3 ports in use, so after some searching and reading on this forum i found this link:
    http://support.apple.com/kb/HT4279?viewlocale=en_US

    This highlights the need for 2 x Apple Mini DisplayPort to Dual-Link DVI Adapter in order for the card to work with 3 monitors - there sell on auction sites for around £40 - £100 each - ouch!
    my question is - my monitors have dvi and vga ports so would it not be cheaper to get 2 x mini display to vga adapters instead of the dual-link dvi ones - AND WILL THEY WORK??

    I would prefer to seek advice before I waste more money on leads that i don't need!

    Thanks in advance for any input. :D

    When you say you upgraded to the 5770. I take it you no longer use your old GPU card?

    Why not just use the old GPU card for the 3rd display. That way its free.

    hi - mjsmke - I've put the x1900xt back in to support the extra monitors but to soak up some of the cost of the new card i was going to sell the old one on.

    DualShock - thanks for the advice, however I can't find any 'active' MDP adapters for sale and also do you know if the MDP > VGA adapters would work?

    Cheers

    As mentioned in my "What We Know So Far" thread (bottom of first post), Dave Baumann from ATI tweeted that NewEgg (in the US anyway) is selling DisplayPort --> single link DVI adapters for ~ $27 US. But these are only DisplayPort, not Mini DisplayPort.

    Otherwise I'm not too sure about availability. But AnandTech did mention September 2010 availability. Also, ATI has a list of certified dongles here (US list it seems, maybe they have a UK list too?):

    But I'm also not sure if these are MDP ones.

    I don't know first hand but at least one person has mentioned that it works:
