The image from my computer appears stretched when it's projected. What should I do?

• Try the following solutions:
  • Press the Aspect button on the remote control to select a different setting.
  • You also may need to modify existing presentation files if you created them for a different resolution. See your software documentation for specific information.
  • Make sure your computer's resolution setting is correct. If this option isn't available, select one of the other supported video display formats.
