• Try the following:
  • Make sure the correct Input Signal is selected in the Signal menu. See Adjusting Signal Settings.
  • Make sure your computer's resolution doesn't exceed UXGA (1600 x 1200) and the frequency or refresh rate is supported by the projector. See Compatible Video Formats. If necessary, change your computer's resolution setting and the screen's vertical refresh rate to match the compatible video format resolution that you have chosen. For 1280 x 800 resolution, for example, you can select a 60 hertz refresh rate.
