    Connect to non-network projector

    Hi, I have tried to connect my new Dell laptop with Vista on it to the Optoma
    DV11 projector using the supplied VGA cable.

    I get NO IMAGE from the projector in spite of all steps shown below.

    1. when cable is inserted Vista automatically changes DPI at 800x600. Is
    there a way of stopping that ? Very annoying...Attempts to change DPI to
    higher at this point crashed the system every time.

    2. have changed DPI to mid range BEFORE connecting the cable. Have cheked
    DPI is in acceptable range for Optoma. This time cable insertion did not
    change dpi to 800x600. Pressed Fn + F8, projector says input acquired via VGA
    channel but screen stays black.

    3. have tried above with Windows Mobility Center, find New Display, etc..Fn
    +F8 again, no luck

    4. all Help in Vista is about network projectors , nothing about directly
    connected projectors. Is a directly connected projector same as a New Display
    or New Monitor ? Can Vista find the directly connected projector ?

    Whatever I seem to be doing, changing DPI, pressing Fn+F8, uisng the
    Mobility Center I get black screen on the projector although the projector
    does lock on some VGA signal from the laptop.
    Am I missing something essential here ? I would be very grateful for some
    advice or help links, thanks.

    Yes I am having similar problems as you with the blank screen. For some
    reason my projector has locked onto monitor 2 setting (in display settings
    VISTA) and only showns this as a desktop image but with no icons or toolbar
    and the resolution looks like its 800X600.

    When I try to change the monitor in settings to the right one (displayed on
    my laptop) the projector shows a blank screen.

    There are quite a few people like us who are having the same problem. It's a
    very common bug in Vista by the looks of it.
