    ATLONA AT-DP400 WITH APPLE 27" LED CINEMA DISPLAY
    • Written by RS from Sherman Oaks
    • Apr 5, 2011

    I've been using the Atlona AT-DP400 Dual Link DVI to Mini Display Port Converter with my new Apple 27" LED Cinema Display and an older MacBook Pro (4,1) for many months now. It has been a great match and I'm getting the full resolution of the display (2560 x 1440) which of course was the big issue for me. I have my laptop closed and tucked under the display with a wireless Apple keyboard. It's a great setup because the display supplies the power to the laptop and also plugs right into the DP400 which sits behind it. Perfect setup given that Apple made this beautiful display without the older DVI plug. Fabulous clarity and color! Thank you Atlona Technologies! …More

    Wonderful adapter!
    • Written by PH from URBANA
    • Apr 6, 2011

    I've had one of these for about 6 months and it's performed flawlessly! It enabled me to connect an older DVI-based MacPro tower to a new 27" LED screen. Without this adapter, I would have been up a creek without a paddle when my old Cinema display bit the dust. Recommend it very highly!! …More

    Excellent Product BUT Does NOT Work with Newer TB Displays
    • Written by JN from Denver
    • Oct 31, 2011

    I was just about to purchase this adapter for my older DVI MacBookPro to connect to my new Thunderbolt 27" iMac (to use it as a larger display for the laptop) but just discovered and CONFIRMED via Altona Tech Support that THIS version of the adapter will NOT work with newest Thunderbold (TB) displays or TB iMacs because...TB is only BACKWARD compatible to DisplayPort and NOT vice versa - i.e., the TB port-out on a newer Mac computer WILL drive an older DisplayPort display, however, the DisplayPort on a previous, "older" Mac will NOT drive the newer TB display OR TB-equipped iMac display ("Mid-2011"). A newer Altona adapter for the latter situation (older to newer, or DVI-to-TB displays) will apparently be available by end of year. Good to know on all accounts and a big thanks to EH from Kungsangen for saving me the time, money and headache. …More

    Does not work with Mid 2011 iMac
    • Written by EH from Kungsangen
    • May 27, 2011

    Seems like the Mid 2011 iMac only supports target display mode via Thunderbolt cables, and the source has to be Thunderbolt too, which means this won't work. I found out the hard way.. Bye bye $199..

    It works well for others though, just wanted to give a warning to those with the same computer.     …More

    Atlona AT-DP400 with Macbook Pro 2.2hz - Excellent except with Aperture
    • Written by DV from RUEIL MALMAISON
    • May 23, 2011

    I bought it six months ago and it works very well both as main monitor or second monitor. The only exception is with Aperture where I can't use the full screen, diaporama and it even reboot the computer sometime when I work on a picture. Big disappointment for me as it was the main reason of the purchase …More

    • Asked by TT from Union
    • Nov 19, 2011

    1 Answer

    Answer

    As long as Mini DisplayPort is based on Displayport and pretty much is the same type of signal, no conversion is needed and you can simply use a DisplayPort to Mini DisplayPort adapter which Atlona carries to different models; AT13022-AD and AT13022-2. …More

  • Will this work with an iMac (mid-2007)?
    • Asked by DS from Vancouver
    • Apr 5, 2011

    1 Answer

    Answer

    No, the DP400 won't work for your application. As long as you have an iMac (mid-2007) as a source which has Mini DVI (video connection type) while 30" Cinema Display's got DVI as a video connection type, there's no need to convert such a video connections(Mini DVI to DVI) using our DP400. For your application, all you need is to use a Mini DVI to DVI adapter and connect your 30" monitor directly into that adapter.


    You may also have to keep this in mind that resolution is going to be limited to 1920X1200 (single-link) as far as Mini DVI's limitation and you won't be able to get the max resolution on your 30" Cinema display which is 2560X1440(native resolution).     …More
