    Hey there..

    i recently purchased a used imac 20" at at very reasonable price..

    Unfortunately the mini Dvi port dosent work properly..

    When i connect with my mini DVi adapter...osx makes the "new screen connected" flash, and my DVI adapter acts as it has been connected..but nothing on the screen...and the system profiler hasent registred any new screens...
    ..on the sideline my old macbook works fine with the adapter and cable..


    is there any other way to get dual screen on my imac?

    i have been looking at the "Kensington Dual display adapter" and though its very expensive i noticed that it had osx support...

    Has anyone tryed this adapter on an iMac? i can see that the drivers are for Macbooks but would this baby work anyways?

    Has anyone tried the adapter out?

    Do you guys have any other suggestions?

    i hope you can help quite desperate :(

    Are you certain that both the mini DVI cable and display are fully functional?

    Do you have warranty left? If you do, call Apple

    This is why you buy AppleCare. If the mini DVI port is truly broken, only an expensive logic board replacement (costs more than AppleCare) can fix it.

    Any kind of external display over USB or Firewire will be seriously limited in what it can display due to the low bandwidth. You would be better off getting a repair or selling this iMac and buying a new one.

    Well it was a used iMac...and the guy previous owner dident buy apple care..

    In what way is external display over USB limited?

    i never wanted to play games on the second screen..

    And i guess that a repair would be = new logic board...and i assume that a new logic board is expensive?
