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 27.

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 28 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 29.

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 27.

The remote’s Effect button 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 32 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 32.

The Startup Logo menu option lets you change the default startup screen to a black, white, or blue screen. See page 32.

Two menu options, Power Save and Screen Save, are provided to auto- matically shut down the projector after several minutes of inactivity or display a black screen. This helps preserve lamp life. See page 31 and page 32.

A Low Power menu option is also available to help lower the projec- tor’s fan sound volume. See page 31.
