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.
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 31.
The  remote’s  Effect button allows you to assign various features to the 
key. The default effect is Magnify. You can select from Blank, Mute, 
Aspect Ratio, Source, Auto Image, Freeze, Magnify, About, and PiP 
Source. See page 37 for details. 
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-
ence seeing them. 
The Blank button on the remote allows you to display a blank screen 
instead of the active source. See page 36.
The PiP Source effect lets you change the video source in a smaller win-
dow on top of the computer image. See page 37.
The Startup Logo menu option lets you change the default startup 
screen to a black, white, blue, or a custom logo screen via Logo Cap-
ture. See page 36.
Two menu options, Power Save and Screen Save, are provided to auto-
matically shut down the projector after several minutes of inactivity or

tor’s fan sound volume. See page 35.
