    Mac Mini lost VDI output - only works with VGA adaptor
    Hello everyone

    I hope some of you can help with I think a very unsual issue with video out on my Mac Mini:

    It only displays video on external monitor if using the VGA adaptor (which gives a blurred image) but if using the DVI output it just gives no signal.

    May I point out that:
    - I rulled out it is a cable problem (works fine on another laptop).
    - I did all the things apple recomends like resetting PRAM, PMU etc. and all it recomends at: Mac OS X: Starting up in Safe Mode

    Also one other element:

    I had the Mac Mini working fine with DVI output at the beginning.
    The issue first occured since I tried a monitor switch/upgrade.
    However now it just does not work anymore in VDI on any monitor whatsoever and tehre is no going back.

    Really appreciate any help you'll be able to give.

    How about some details? What year model Mac Mini, which version of OS X? Monitor brand model? In the meantime try resetting the SMC.
