SYMPTOMS

Consider the following scenario:
  • On a Windows Vista-based portable computer, you run Windows Media Center in full-screen mode.
  • The portable computer has a wide screen, and the screen resolution has been configured for wide-screen resolution. For example, the screen resolution is set to 1280 by 800 pixels.
  • You connect the portable computer to an external monitor by using an S-Video connection.
  • You try to switch the screen to the external monitor by using the function key on the portable computer.

    Note The particular function key to switch the screen between monitors varies, depending on the computer manufacturer.
In this scenario, you may notice that the screen has been successfully switched to the external monitor. However, the screen is black, or it appears to be otherwise broken.
