Optimizing computer images
After your computer is connected properly and the computer’s image is on
the screen, you can optimize the image using the onscreen menus. For gen-
eral information on using the menus, see page 31.
• Adjust the Keystone, Contrast, or Brightness in the Picture menu.
• Change the Aspect Ratio. 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. Choose the option that best fits your
input source. See page 32 for details.
• Adjust the Color Temperature in the Advanced menu.
• Adjust the Phase, Tracking, or Horizontal or Vertical position in the
Advanced menu.
• Once you have optimized the image for a particular source, you can
save the settings using Presets. This allows you to quickly recall these
settings later. See page 33.
