    Hi all -

    I've recently bought a shiny new MacBook Pro -

    -model - MacBookPro 8.2
    -processor name IntelCore i7

    and am trying to connect it to my monitor -


    using a DVI cable and overpriced apple Mini DisplayPort to DVI adapter. When i make the connection and select the Input from the monitor menu - I just have a black screen. I've installed a handy little mac app called gfxCardStatus in order to experiment with Discrete only and Integrated only modes but no success.

    Any clues or suggestions greatly appreciated! -

    I had the same problem - try using SwitchResX control panel/pref pane software.
    Although the EDID on the P221w says one thing I suspect a batch may be wrong.
    I had to set a custom res up with SwitchResX using the following and it worked for me.
    1680 x 1050
    0 0
    152 6
    152 8
    304 14
    1984 1064
    60Hz 56.391 Hz
    Pos and Neg sync boxes ticked. No interlace.
