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.
Presentation features
Several features are provided to make giving presentation easier. The fol-
lowing is an overview, details are found in the menu section on page 29.
The remote’s Effect Key allows you to assign various features to the key. The
default effect is About, which displays information about the projector and
current source. You can select from Blank, Mute, Aspect Ratio, Source, Auto
Image, Freeze, Zoom, and About. See page 34 for details.
The remote’s Freeze effect allows you to freeze the displayed image. This is
useful if you want to make changes on your computer without your audi-
ence seeing them.
The Blank key on the remote allows you to display a blank screen instead of
the active source. See page 34.
The Startup Logo menu option lets you change the default startup screen to
a black, white, or blue screen. See page 34.
Two menu options, Power Save and Screen Save, are provided to automati-
cally shut down the projector after several minutes of inactivity or display a
black screen. This helps preserve lamp life. See page 33 and page 34.
A Low Power menu option is also available to help lower the projector’s fan
sound volume. See page 33.
