44 Using the 4000i
Adjusting the Projector Settings
You can adjust the brightness and contrast levels for each source independently of all other
sources. The 4000i then saves your settings. For example, if you increase the brightness of
the display from the VCR, the brightness for the computer’s display is unaffected.
To adjust the image brightness, press either the Increase Brightness button or the Decrease
Brightness button on the control panel.
To adjust the image contrast, press either the Increase Contrast button or the Decrease
Contrast button on the control panel.
The default levels of brightness and contrast are set to the midpoint. You can restore either
default by pressing both brightness buttons or both contrast buttons simultaneously.
When you initially connect the projector, you may need to fine-tune the projected image. The
lens in the projector isn’t motorized, so you can’t use the buttons on the remote control to
focus the image. Instead, you must manually rotate the projector lens.
To move the image up or down on the screen, use the Lens Shift button on the projector or its
remote control. To eliminate vertical banding of the image, press the Tracking button on the
projector.
After you’ve adjusted the image, you can optimize it by pressing the Auto button on the
projector or on the remote control.
TIP
You can hold down a Brightness or Contrast button to make continuous
adjustments.
