Why dual head videocard does not support 2 monitors?

    I have a dell desktop Demension 8300 with NVIDIA GeForce4 MX 440 with APG8X. This card has 2 heads, one is vga and the other is degital.

    I go into set up, but I don't see the option to Extend from the first monitor to the second monitor.

    Is the card problem, or I have a wrong driver?
  2. That card should run dual monitors. (Some cards have both DVI and VGA ports to accommodate EITHER type, though not capable of running 2 monitors.)

    Try the most current driver. If still no dual display, perhaps one of the ports is bad or it can't display 2 montors in spite of having 2 ports.

    how do i know if i get the LASTEST driver?
    should older drivers at least show the option for dual heads?
    mine setup does not even have this option.
  5. Check the Nvidia website. It will list a current Universal Driver for your card. If it's different than the one you're running, uninstall the old and install the new.

    If it still doesn't show the dual icons in Display/Settings, either it never was capable of dual monitor or one port is bad. There would not be a case where an older driver allowed dual display while a new one did not.

    Is this the first time you've tried to initiate dual display on this card?
  6. Why can't you spell?

    It's Dimension 8300... and that thing must be at least 3-4 years old.

    You do not provide enough information for anyone to help you.
