How to Connect Two Computers With an RGB Cable

RGB cables deliver color video signals far superior to old analog cables. RGB stands for Red, Blue, Green, the primary colors used in signal separation and transfer between one digital device to another. You can connect two computers with an RGA cable using the 15-pin VGA (Video Graphics Array) ports on the back of each computer, then send video from one computer for display to the monitor on the second computer.

Things You'll Need

• Two computers
• RGB cable

Instructions

1. Log off and power down both computers before making connections.

2. Designate one computer as the output and the other computer as the input for receiving video from the first computer.

3. Plug the 15-pin RGB plug into the VGA output jack of the first computer and tighten by hand the two screws on either side of the plug.

4. Plug the 15-pin RGB plug on the other end of the cable into the VGA input jack of the second computer and hand-tighten the screws on that plug.

5. In a Windows platform, go to control panel or personalization, then choose display settings and select setup for two monitors.
