I am having trouble successfully installing an add-on graphics card to host a second monitor, in addition to the built-in/on-board display adaptor, on my Dell Dimension 4700 PC with Windows XP OS.

System Spec:

Dell Dimension 4700 - new.
Diamond Stealth Express - Radeon X300SE PCI Express DVI/TV-Out adapter
Windows XP Pro
On-board built-in Intel graphics port
Dell 17" LCD monitor
Dell 19" monitor

Symptoms:

System will not let me connect both monitors --- one to the onboard port, the other to the add-on graphics card. I can't configure the adapters/monitors in display settings. In fact, display settings does not show two monitors like it does _before_ I added the graphics card. Monitor works fine if I plug it into either port.

Other Problems:

Unfortunately, the Diamond Stealth Express does not appear to be Microsoft approved hardware. I have trouble knowing if the proper driver is installed. (However, the display works fine as is.)

Can anyone give me some hint as to what's going on and maybe suggest how I get around this problem?

Much thanks in advance...
