HP PCs - Using two or more monitors with one computer (Windows 10)
Learn how to duplicate or extend your desktop display. Connect and set up a television (TV) or an additional monitor to your computer.
-
Duplicating (or cloning) the desktop displays the same image on both screens. Duplicating is most commonly used for presentations.
-
Extending expands the desktop display across both screens. Extending is most commonly used to get more workspace.
Check your computer specifications to see if multiple monitors are supported on your PC. You can add another video card to some desktop PC models to provide an additional video connection. When adding another video card, make sure the new card uses the same drivers as the current Windows 10 compliant driver.
You cannot install an additional video card on laptop PCs. Most laptops support external monitors. Check your product specifications to learn about external monitor support for your model.

Connecting the second monitor to your computer
Computers and TVs have a wide variety of video connection types. The video connection on your computer must match the connection on your TV or monitor.
If your PC only has DVI and your TV does not have a DVI port, you can use a special adapter or converter cable.
Connecting another monitor using cables
Connect another monitor to your computer using cables.
Connecting another monitor with a wireless connection
Miracast is a wireless technology that projects the image from your computer screen onto another monitor, TV screen, projector, or streaming media player that also supports Miracast. You can use this to share what you are doing on your computer, present a slide show, or even play your favorite game on a larger screen.
For more information, go to HP PCs - Sharing Your Screen Using Miracast (Windows 10).
Troubleshooting TV setup
If you have problems connecting a TV to the computer, consider the following.
-
Turn on the TV before turning on the computer.
-
Use only one video source per monitor device. Do not connect two cables to the same TV or monitor unless it supports picture-in-picture.
-
Make sure your TV supports sound with your connection type, or use a separate audio cable connection.
-
If the computer cannot detect the TV, set the TV as the primary monitor device, and then restart the computer.
-
Make sure your TV input source matches the video source that you are using. On the TV remote control, press the Source or Input button. Input 1, HDMI 1, or S-video or similar options might be available, depending on your TV. If your TV does not have this option, you cannot use it as a second monitor without using special video signal processing (not covered in this document). For more information, see the manual for your TV.
-
If you are using a coaxial or S-video connector, set the desktop screen resolution to 800 × 600 (or less).
-
Adjust the aspect ratio to scale the image to the screen you are using.
-
Make sure that the signal format of the TV matches the signal output of the card (for on-board TV-output, this setting can be changed in the BIOS). For standard analog signals, a TV accepts either a PAL (Europe) or NTSC (North America) signal.
Configuring the monitor
Configure your monitor for presentations or for more desktop space.
Configuring the monitor with Windows
Extend or duplicate the desktop with a second monitor.
Configuring the monitor with the display driver
Use the video or graphics card driver to configure screen settings.
Enhancing and personalizing your monitors (optional)
After attaching an additional monitor, enhance and personalize your monitor.
-
Taskbar: Right-click on the taskbar, and then select Taskbar settings. Click the drop-down menus to set your taskbar preferences.
-
Start screen: On an extended desktop, the Start screen displays only on your primary monitor.
-
Background image: Right-click anywhere on the desktop, and then click Personalize. Select images, colors, and themes.
The following images show examples of different images on each screen and one image spanning both screens.
