20 Optimizing video imagesYour projector has been factory optimized for very good performance no matter what the source. However, if yo u wish to make further changes you can optimize the image using onscreen menus. For general information on using the menus, see page 21. Adjust the Keystone, Contrast, Brightne ss, Color, or Tint in the Picture menu ( page 22). Select a Sharpness setting ( page 24). Use the Color Control to adjust the color gain and offset ( page 25). Adjust the Color Temperature. Select a listed value ( page 25). Turn on Overscan to remove noise on the edges of the video image ( page 25). Change the Aspect ratio ( page 22). Aspect ratio is the ratio of the image width to image height. TV screens are usually 1.33:1, also known as 4:3. HDTV and most DVDs are 1.78:1, or 16:9 (the projector ’s default). Choose the option that best fits yo ur input source in the menus, or press the Resize button on the remote to cycle through the options. See page 18. Select a specific Color Space. See page 24. Select a different Video Standard. Auto tries to determine the standard of the incoming video. Select a different standard if necessary. See page 25. Make sure your DVD player is set for a 16:9 television. See your DVD player ’s user ’s guide for instructions. Customizing the projectorYou can customize the projector for yo ur specific setup and needs. See page 26 to page 28 for details on these features.
