connecting two monitors to a pc
You will need two video out connections on the back of your computer, one for each monitor. There are 4 main types of connections, listed from oldest to newest: VGA, DVI, HDMI and Display Port. For best results, use two of the same connectors for your dual monitor setup. If you have a monitor with a VGA cable, and your port is DVI, you can purchase an adapter that will attach to your VGA connecter and allow you to hook it up to a DVI port. 2  The ability to set up dual monitors depends on the power of your graphics card and CPU.
