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. See page 30 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 31.

Adjust the Room Lighting. Select Dark if you are in a dark room, Light if in a bright room (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 button allows you to assign various features to the key. The default effect is Freeze. You can select from Blank, Mute, Aspect Ratio, Source, Auto Image, Freeze, Zoom, About, PiP, and Mask. See page 35 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 34.

The PiP effect lets you show a video source in a smaller window on top of the computer image. See page 35.

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 auto- matically shut down the projector after several minutes of inactivity or display a blank screen. This helps preserve lamp life. See page 33.
