Make sure the computer can support the second monitor. Although Windows 10’s setup allows for multiple monitors, not all graphics cards support multiple monitors. You can quickly check if your desktop or laptop has support for a second monitor by looking at the video output: [1] X Research Source
- For desktops — At the back of the desktop tower, look for an empty video output port. If you see a port next to or just above the port being used to connect the desktop to the first monitor, you can use the second monitor.
- For laptops — Any laptop with a video output port (such as HDMI, DisplayPort, or USB-C) can support a second monitor.

Specify the required connector type for the second display. Most newer computers and monitors use HDMI or DisplayPort cables. If you have an older computer or monitor, you’ll likely see a color and trapezoidal VGA connector.
- If there’s an empty video output port, matching the connector on the back of the second monitor, it’s best to use a cable that fits both connectors.
- If your computer uses a different connector than your monitor, you can purchase an adapter cable (such as USB-C or HDMI) or an adapter (such as VGA or HDMI).

Set the second monitor. If you want to extend the first monitor to use the second as an additional monitor, you need to place the second monitor to the right of the first.
- If you just want an extra screen like the first, you can place the second monitor anywhere.

Attach the second monitor to the computer. Plug one end of a video cable (such as HDMI) into your computer’s video output jack, then plug the other end of the cable into the second monitor’s video input jack.
- If you’re using an adapter, you may need to plug both cables into the adapter and/or plug the adapter into a power source before connecting the monitor to the computer.
