Setting up a PC to run three monitors requires a dual-head video card.
Running three or more monitors from a PC is quickly accomplished by adding a dual-head video card to the computer. There are several uses for multiple monitors, including having a larger desktop area to work with and for gaming. Windows allows you to duplicate the monitors (mirror mode) or run each monitor individually (extend mode).
Instructions
Install the Video Card
1. Unplug the computer from the electrical outlet. Be sure to discharge the static electricity from your body by touching something metallic other than the computer before attempting to open the computer case. Static electricity can damage internal computer components.
2. Open the computer case. Looking directly at the back of the computer, there are two screws on the right side of the computer that can be removed with a Phillips screwdriver to access the inside.
3. Install the video card by carefully inserting it into an available slot. A single Phillips-head screw will fasten the video card to the computer's motherboard.
4. Close the computer case and replace the two screws removed previously.
5. Connect the monitors to the monitor ports on the video card.
6. Power on the computer.
7. Install the driver software for the new video card. It is recommended to download and use the latest version of the driver software from the video card maker's website, such as ATI or nVidia.
