    I have a 2011 13/256 air and every time I disconnect the rgb:mini display adapter after giving a presentation in powerpoint the resolution does not revert back to the native setting. Tonight I tried to plug the adapter back in to see if it would reset the resolution, but the mac display went blue and I had to force restart. The display adapter is not aftermarket, but it works perfectly in every other respect. So I have a few questions

    1) Is it normal to have to manually change the resolution back after disconnecting a display?

    2) Is there a toggle on the mac to go back and forth between displays (like the function key plus one of the F keys on a PC)?

    3) Could this be a problem with the adapter?

    I think in mirroring mode, the resolution doesn't change automatically as far as I know. You might want to try changing settings to not mirror displays and see if that helps -- then your primary display settings remain unchanged.

    As to #2 & #3, I believe the answer is no to both.
