Optimizing Computer Images; Presentation Features - InFocus LP650 User Manual

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 29.
• 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 30 for details.
• Adjust the Color Space or 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 31.

lowing is an overview, details are found in the menu section on page 29.

• The Freeze effect allows you to freeze the displayed image. This is use-
ful if you want to make changes on your computer without your audi-

screen to a black, white, or blue screen. See page 34.

page 34.

tor's fan sound volume. See page 33.
