Had this problem with a Gateway that I was working on. There are two ways to do it, the first requires two monitors. The second uses one monitor.

Here's the one monitor method:

• Install the card and drivers for the new video card. (which you've already done)
• Connect your monitor to the onboard video card connector and boot the system.
• Open you Display Properties window (right-click on desktop and select properties).
• Click settings tab.
• You should see two monitors available in the box. Click on monitor 2 to highlight it.
• Below and to the left are two boxes, first check the box marked "Extend my Windows desktop to this monitor" and click Apply.
• Next check the box marked "Use this device as my primary monitor".
• Select monitor 1 and uncheck the box marked "Extend my Windows desktop to this monitor" and you monitor should go black and shut off.
• Now move the monitor connection to the new video card
• Your display should now be on the new monitor

The two monitor method uses the same steps but you use two monitors so you can see the changes taking effect on both connections at the same time.

Don't worry about hot-plugging the monitor while the computer is running, there is no danger to the hardware in doing this.
