Help! Add-on graphics card for a 2nd monitor

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...
 
Dual monitors can be problematic when jusing 2 seperate cards (works better with a dual head video card) - especially when using an old card like a Diamond Stealth.

The Diamond Stealth does not work properly under WinXP - trust me. I have a box of them I pulled from a client's computers when he upgraded to XP.

I would recommend you find a newer card than that Diamond Stealth - some cheap modern card like a Radeon 7000, or even a Geforce MX 200. Even an NVidia TNT2 would work.



 
With windows xp (both home and Pro) there are a specific set of video drivers that must be used to enable dual monitor support. This only applies if you are not using a vid card that is not a dual headed card, IE 2 video cards. The reason is that the video cards must be installed to utilize the drivers supplied by windows and not by the manufacturer for this to work. Dig deep into microsoft support and you'll find the list.
 
My bad - I misread your original post - I thought you were using an OLD Diamond Stealth, not a modern one.

You'd be much better off getting a dual-head video card and just disabling the onboard card. Does your X300 have dual display outputs?
