    First Name:
    I have had two video cards in this machine (Windows XP Home SP2) in the past for a dual screen setup..
    Today I put in a 2nd video card again (as the one that was in there previously has gone walk-about) but I dont have the option in windows for the 2nd screen.

    Everything appears fine in device manager (the screen that is working is the PCI ViRAGE one), as for the GeForce - well the light on the monitor comes on but doesnt display a picture, but in display properties there is no option for the 2nd card. (see attached screenshot)

    Any ideas? - I've tried uninstalling/Reinstalling the Geforce, and the ViRAGE, but I cant get it work..

    Any Suggestions to why the option isnt appearing?

    I did a search for this and got this:

    To install additional monitors
    Turn off your computer.
    Insert your additional Peripheral Component Interconnect (PCI) or Accelerated Graphics Port (AGP) video adapter into an available slot.
    Plug your additional monitor into the card.
    Turn on your computer. Windows will detect the new video adapter and install the appropriate drivers.
    Open Display in Control Panel.
    On the Settings tab, click the monitor icon that represents the monitor you want to use in addition to your primary monitor.
    Select the Extend my Windows desktop onto this monitor check box, and then click Apply or OK.
    If the check box is not displayed on your computer, it may be because your video adapter does not support multiple monitors. See Notes for information about compatible hardware.


    To open Display, click Start, click Control Panel, and then double-click Display.
    Selecting the Extend my Windows desktop onto this monitor check box allows you to drag items across your screen onto alternate monitors.
    Or, you can resize a window to stretch it across more than one monitor.

    To use the multiple monitor support feature, you need a PCI or AGP video adapter for each monitor. If you have an onboard video adapter (one that is not a plug-in card but is part of the motherboard) that you want to use as part of a multiple-monitor configuration, it must be set as VGA.
    To find hardware that is supported by Windows operating systems, visit the Windows Catalog on the Microsoft Web site.

    If your computer doesn't recognize your second monitor, click Display Troubleshooter for more information.
    The operating system always needs a VGA device. The computer's BIOS or EFI detects the VGA device based on slot order, unless the BIOS or EFI offers an option for choosing which device is to be treated as the VGA device.
    The VGA device cannot be stopped, which is an important consideration for docking units.
    The monitor that is designated as the primary monitor will display the logon dialog box when you start your computer. In addition, most programs will display windows on the primary monitor when you initially open them.
    If you are using Dualview, skip steps 2 and 3 above. Just plug your second monitor into the video out port on your portable computer, or into the second video out port on your desktop computer. When you turn on your computer, it should recognize the second monitor. Follow steps 5 through 7 to extend your display to the second monitor. If the second monitor is not shown on the Settings tab, you might need to update your display driver.
