If the image is stretched:
• On the projector or remote control, press the picture mode   button one or more times 
to see if one of the picture modes makes the image the correct size.
• Press enter, go to Picture > Customize picture mode > Aspect ratio. Try the different 
settings.
• If the source device sends wide-screen output, press enter, go to Source, and try setting 
Widescreen input to On. Otherwise, set it to Off.
If the projected colors seem slightly wrong:
• Press enter, go to Help > Diagnostics, and run the color test.
If the projected colors seem completely wrong:
• Be sure the pins on the cable connectors are not bent or broken.
• Press enter, go to Help > Diagnostics, and run the color test.
• Press enter, go to Picture > Color settings > Reset color settings, and press enter.
• Press enter, go to Setup > Advanced settings > Reset all settings, and press enter.
If the picture is not clear (ghost images, smearing, poor quality):
• Be sure the video cable you are using is coaxial cable rated at 75 ohms. Any other 
cable or impedance rating can reduce picture quality.
• The video cable connecting the video source to the projector probably must be higher 
If several picture settings seem completely wrong and you cannot fix them:
• Press enter, go to Picture > Color settings > Reset color settings, and press enter.
• Press enter, go to Setup > Advanced settings > Reset all settings, and press enter.
If a scrolling or cut-off image is displayed for a computer connection:
• Press  the  auto sync button on the projector or remote control.
• Turn everything off. Then power on the projector first and power on the notebook or 
desktop computer second.
• If the previous steps do not correct the display image, adjust the resolution of the 
notebook or desktop computer to the same resolution as the projector, 800 × 600 or 
1024 × 768 (see “Specifications” on page 61). If the computer has multiple monitors, 
adjust the resolution of the monitor assigned to the projector.
