Dual Monitor Cables Plug the power cords into your power strip. Connect the first monitor to your computer through the HDMI port or through a VGA port, if desired. Do the same for the second monitor. If your computer only has one HDMI port and one VGA port, which is common, find an adapter to complete the connection.

Can I use dual monitor without GPU?

Yes, your motherboard and integrated Intel graphics supports up to three monitors at once. You can use the HDMI port for one monitor and use the VGA connector for the other. You could also buy a DVI -> HDMI cable to connect the 2nd monitor if you prefer not to use VGA.
