    Hi all.
    I've got a mac pro with an X1900XT video card with dual DVI outputs. I've got a 23" ACD as my main display and I sometimes connect my TV via composite (using the Apple DVi to video adapter). When I'm not using my TV with my Mac, I unplug the adapter.

    Everything was working fine up, but now my Mac doesn't seem to detect the second display. When I connect the DVI plug into the computer, my main dispplay goes blue for a second (as it usually does, i think), but then nothing happens.

    Can anybody help?

    Try doing this:

    Sys Prefs ==> Displays ==> Dectect Displays

    The thing is, it worked fine when I first got it. But one day, it just suddenly stopped working.

    Same Problem!

    Have been using MacPro to connect to my 52" Sony Bravia with HDMI 1. All of the sudden today its not working. When I plug into computer, screen goes blue and then the my entire page looks like everything is enlarged and abnormal. Its trying to connect to the tv, but there is nothing showing on the TV. Any help??
