How does Windows 8.1 connect to a second monitor or projector?

Having a second screen helps you view multiple open apps at the same time. You can also connect a projector so that everyone in the room can see your screen.

Most monitors and projectors can be connected using a DVI, VGA or HDMI cable. (Some devices can even be connected wirelessly. For information, see Projecting to a wireless display using Miracast.) Your computer may have one or more of the following ports.

DVI, VGA, and HDMI Ports

After connecting your monitor or projector to your computer, you can do the following:

Use the four corners or touch screen of any screen with your mouse The edge opens the "Start" screen, the charms, and the most recently used apps.

Open multiple windows on each screen and run one app in each window.

Customize your screen by displaying the taskbar on one or all of the displays and moving the app between screens.

1. Connect the monitor to your computer

You can plug in most monitors and projectors with a cable that matches the DVI, VGA, or HDMI port provided on your computer. If your computer has only one DVI port that is already in use, but some computer manufacturers come with a custom display cable, you can split the signal from one DVI port to two.

Note

Desktop computers require a video card with two DVI, VGA or HDMI ports.

If the monitor or projector cable does not match your computer, you can use an adapter to convert one type to another (for example, to help insert a DVI monitor into your VGA port, and vice versa) .

2. Steps to connect another monitor to your computer

Find available video ports on your computer.

Insert the matching cable from the second display into this port.

Windows should automatically detect and install the monitor.

3. Connect the projector to your computer

For a wired connection, plug the projector cable into your VGA, DVI or HDMI port. In most cases, Windows will automatically detect and install the projector.

When "Wireless Projector" is detected nearby, "Windows" can also be connected. For more information on connecting a Miracast wireless projector, see Projecting to a wireless display using Miracast.
