  1. Hi,

    I have an ATI Radeon 9550 with tv out. Now i wanted to extend my desktop to
    the tv (for running media center on it) but it seems not to work :(

    When i click on the Extend the desktop onto this monitor for the second
    screen and click apply, my first screen flikkers few times but not get
    extented, each time the extend option is set of again

    Installed the ATI beta drivers, still not working.

    Is this a vista bug or has this something to do with my card?

  2. I've just tried to repro this one by extending my desktop onto a spare
    television I have - doesn't work for me either. I've got two monitors it
    says in the Display panel - both saying Multiple Monitors on Mobility Radeon
    9000/9100 and it won't work for me either (before anyone says so, I've got
    Classic theme on seeing as Glass isn't supported... I know!)

    I've tried different resolutions, different settings, Identifying, but
    nothing :eek:( I'll file a bug :eek:)

    I had this problem also but resolved it by installing the NVidia drivers
    from their site (as I have a 6800).
    It looks like the Microsoft (Nvidia/ATI) card drivers don't support multiple
    active screens.

    You might want to check the ATI site about this support in their Vista
    drivers and offcourse does anyone from Microsoft know about a fix/work
    around for it?

    I have an ATi 9700 Pro, and I've had no problems with dual screens using
    either the standard drivers or the ATi drivers.
