How does Windows 8.1 connect a second monitor or projector?

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

You can use a DVI, VGA, or HDMI cable to connect most monitors and projectors. (Some devices can even connect wirelessly.) For information, see projecting to a wireless monitor using Miracast. Your computer may have one or more of the following ports.

DVI, VGA, and HDMI ports

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

Use the mouse to open the Start screen, the Super button, and the most recently used application using any of the four corners of the screen or the edge of the touchscreen.

Each screen opens with multiple windows, running an application in each window.

Customize your screen by displaying the taskbar on one or all monitors and moving applications between screens.

1, connect the monitor to the computer

You can plug in most monitors and projectors with cables that match the DVI, VGA, or HDMI ports available on your computer. If the computer has only one DVI port already in use, some computer manufacturers come with a custom display cable that decomposes the signal from one DVI port to two monitors.

Attention

A desktop computer requires a video card with two DVI, VGA, or HDMI ports.

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

2, to connect another monitor to the computer steps

Look for available video ports on your computer.

Plug a matching cable from the second monitor into the port.

Windows should automatically detect and install the monitor.

3, connect the projector to the computer

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

You can also connect when Windows detects a wireless projector nearby. For more information about connecting Miracast wireless projectors, see projecting to a wireless monitor using Miracast.

4, connect to the wireless projector steps

Swipe from the right edge of the screen to the middle and click on "Device". (If you use the mouse, point to the lower-right corner of the screen, and then move the pointer up, and then click Devices.) )

Click or click Drop Shadow, and then click or click Add Wireless Monitor.

Select the projector in the list of found devices, and then follow the instructions on the screen.

5, set the content on the screen

After you insert a second monitor or connect the projector, you can select the screen option.

Swipe from the right edge of the screen to the middle and click on "Device". (If you use the mouse, point to the lower-right corner of the screen, and then move the pointer up, and then click Devices.) )

Click or click Drop Shadow, and then choose one of the following options:

computer screen only. You will see all the content on the computer. (this option is changed to disconnected when you connect to the wireless projector.) )

Repeat. You will see the same content on two screens.

Only a second screen. You will see all the content on the connection screen. The other screens will be blank.

6. Use taskbar on all screens

After setting a second monitor or projector based on your preferences, you may want to set up multiple taskbar settings to make it easier to switch between applications and files on your desktop. The following describes how to set up the taskbar on all monitors and how to change the way buttons on the taskbar are displayed.

Swipe from the right edge of the screen and click Search (point to the upper-right corner of the screen if you use the mouse, then move the pointer down, click Search), and then type "Taskbar and navigator" in the search box.

To move desktop applications to the left, center, and right side of the screen, and then move to the next monitor, press the Windows logo key + RIGHT arrow and the Windows logo key +shift+ left.

8. Control the cursor behavior when one monitor is a touchscreen and the other is not a touch screen

If you connect to your computer with both a touchscreen display and a non touch screen display, you may need to change the settings for your cursor.

Swipe from the right edge of the screen, click "Search" (if you use the mouse, point to the upper-right corner of the screen, move the mouse pointer down, click Search), type "tablet settings," and click or click "Tablet settings."
