HP PCs - Using Two or More Monitors with One Computer (Windows 10, 8)

This document is for HP and Compaq computers with more than one video connector, using Windows 10 or Windows 8.
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 the desktop expands the work area across both displays. Extending is most commonly used to get more workspace.
You can add another video card to your computer to get another video connection. Make sure both video cards use the same Windows 10 or Windows 8 compliant (WDDM) driver.

Step 1: Connect the second display

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.
  1. Select a connection type based on your second monitor.
    • Monitor: VGA or DVI cable
    • TV: Video (composite) or S-video cable
    • High Definition TV: DVI or HDMI cable
  2. Connect the TV or monitor to the computer using the cable you chose.
  3. Connect a power cable to the TV or monitor, and then turn it on.
  4. TV connections only: Change the TV video input source to match the video source connection from the computer (Line-1, Video-1, HDMI, etc.). Refer to documents that came with the TV for instructions.
    Depending on the TV, the image quality might not be as good as that of a monitor.
  5. Turn on the computer.

Step 2: Configure the display

Use the steps in this section to configure your display for presentations or for more desktop space.

Step 3: Enhance and personalize your displays (optional)

After attaching an additional display, enhance and personalize your display.
  • 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.
  • App tiles (Windows 8 only): On the Start screen, drag tiles from one monitor to another. If the app is snapped, it snaps on the other monitor, too.
  • Background image: Right-click anywhere on the desktop, and then click Personalize. Select images, colors, and themes.
