This is a typical dual-head graphics card.
Most modern discrete graphics cards, including the Nvidia GeForce 8800 GT, include connections for two or more monitors. Using multiple monitors can be a great way to enhance productivity, extend viewing space, or just plain have fun. The setup of a multiple monitor system is straightforward, if a little tedious. You'll be using two monitors to display information usually formatted for just one, so some adjustment and calibration will be required. Remember, if you find yourself looking at a black screen, restart with your normal setup and it should reset.
Instructions
1. Having two monitors working simultaneously can be a great way to do work or have fun.
Power down your computer and both monitors. Examine your monitors' cable connections and determine if they use VGA or DVI connections (they may differ from one another.) See the attached image: the small, blue jack is VGA, the long white jack is DVI.
2. Connect your monitors to both DVI jacks on the back of your computer using the DVI cables. If one or both monitors have only VGA connections, attach the VGA adapter to the graphics card and connect the VGA cable to the adapter.
3. Power on your computer. Login normally. If both monitors are functioning and the pixels look sharp, you're finished. If only one is working, or if the layout or formatting of the images looks wrong, continue to Step 4.
4. Right-click an open area of the desktop and select "Properties," then click the "Settings" tab. (For Windows Vista users, select "Personalization," "Display settings." For Windows 7 users, just select "Screen Resolution" from the right-click menu.)
5. Use this window to adjust the resolution, relative position, and color quality of your monitors. A monitor must have either "use this device as the primary monitor" or "Extend my Windows desktop onto this monitor" selected before it will function. Only one monitor can be the primary monitor, and it is the default home for the Start Button and Taksbar.
