    Second screen not working with Mac Pro after Mountain Lion upgrade

    Before Mountain Lion upgrade it was actually working without any issues in my Mac Pro while connecting the second screen but now it just doesn't work at all after the upgrade. Is there any bug or so in Mountain Lion or some more settings need to be changed? Kindly give me the information on this.

    Hello friend,


    I have the solution for your problem just do as i say..................

    1.This may be the problem of the settings or the screen resolution.

    2.So you try to change the screen resolution as you used in before OS.

    3.Then you connect your Mac to second screen.

    4.Still if you have the problem then the problem is with the update.

    5.So you open the Time Machine and the perform Restore.

    6.Still if you have the problem the you have to install the OS files again.

    All the best...............
