  • PrintPrint
This document pertains to HP Notebook PCs with Windows Vista.

Requirements for using multiple displays

This document explains how to connect and set up a television (TV) or a monitor as a second display.
Make sure the computer has at least two video connections: one for the main monitor and one for the secondary monitor or TV.
To connect a TV or second monitor as a second display, first identify the type of connection needed, and then connect the TV or the monitor.

Select the type of connection you want to use

The latest computers and TVs offer a wide variety of video connection options. The video connection on the computer must match the video connection on the TV or monitor. Select the connection type from the table below. Adapters are available for connections, such as DVI to HDMI; however, they may not be fully compatible for video or audio needs. Refer to the documentation that came with the TV or monitor for more information.

Configure the display settings

The following describes how to set up the two most common multiple display configurations:
Presentation or Mirrored : This displays a duplicate (mirrored) image on two monitors, or a monitor and a projector. This configuration is most commonly used for presentations; that is, the presenter works from a smaller monitor while the audience views the presenter’s work from a larger TV, monitor, or projector.
Extending the desktop : The Windows desktop or work area extends across both displays. This configuration is most commonly used to get more workspace. Users can take advantage of the extra workspace to view different applications on different displays.

Presentation or mirrored display mode

  1. Right-click an empty space on the desktop, and select Personalize .
  2. Select Display Settings
  3. When the New Display Detected dialog box appears, the images on both of the displays will be automatically mirrored.
  4. (Optional) To adjust the resolution, so that the display area of the monitors are the same size in the Display Settings window, select a monitor and slide the resolution slide bar. Click OK to save the setting and exit.
The computer is now ready to display the same screen on all output devices, from monitors to projectors. Press the fn and f4 function keys at the same time to switch the image from the notebook display, to the external monitor, or to both.

Extending the desktop

  1. Right-click an empty space on the desktop, and select Personalize .
  2. Select Display Settings
  3. Select the monitor representing your second display. Click the Extend the desktop onto this monitor checkbox and click OK .
    NOTE:To help identify your monitors, click Identify Monitors . The numbers 1 or 2 are shown on the monitor icons to help you identify them.
  4. (Optional) To adjust the resolution, in the Display Settings window, select a monitor and slide the resolution slide bar. Click OK to save the setting and exit.
  5. (Optional) To change the direction the desktop will extend (left or right to match how the displays are physically set up), select a monitor and drag it to the desired position.

Troubleshooting TV setup

Try the following items if you encounter problems when trying to connect a TV to the computer:
  • Certain display adapters need to have TV set as the primary display adapter before it can be recognized at all. If the computer is not "detecting" the TV as a display device when the computer is turned on, set TV as the primary display device in Windows and restart the computer.
  • Turn on the TV before turning on the computer.
  • TVs require their source setting to be changed to the video source that the video card is using. Select either Input 1 , Input 2 , or S-video by pressing the Source or Input Source button on the TV's remote control. This can vary depending on the type of TV you are using. If your TV does not have this capability, then you will not be able use it as a second monitor without using special video signal processing (not covered in this document). For more detailed instructions, consult the manual for your TV.
  • Set the screen resolution to 800 x 600 or less from Display Properties on the computer.
  • Use only one video source. Do not connect two cables to the same TV or monitor.
  • A TV accepts either a PAL (Europe) or NTSC (North America) signal, depending on the country it was made for. Make sure that the signal format of the TV matches the signal output that the card produces (for on-board TV-output, this setting can be changed in the BIOS).
