    I have plugged a Dell 2709W Monitor into my MBA 13" 2011 over a Minidisplayport - DVI Adapter. The MBA recognizes the monitor as Dell 2709W but the monitor itself does not get an image. All it says is: "no signal"

    From my Windows PC the signal is working.

    What can be wrong? thunderbolt issue?

    I have a 30" Dell monitor I am wanting to try, but I am wondering if the dual link DVI adapter is needed for bigger monitors? I have no clue, just uneducated speculation. :D
