Display Device: The options in the Display Device menu allow you to perform various
adjustments at the projector.
• Configure: Select Configure from the Display Device menu to change the picture
orientation, correct a “keystoned” (trapezoidal) image, access the lamp timer, perform
lens adjustments and quickly optimize various display settings.
• Installation - Orientation: Refer to Adjusting the Picture Orientation on
page 37.
• Installation - Keystone: If the projector and screen are not installed perpendicular
to each other, the image may become distorted in a trapezoidal shape, as shown in

• Installation - Lamp Hours: This menu page also displays the number of hours that
the lamp has been in service. To reset the counter (which is recommended after you
replace the lamp), refer to
Lamp and Filter Replacement on page 73.
• Lens: Select Lens from the Display Device menu to access the motorized lens
controls. Refer to
Primary Lens Adjustments on page 37.
• Auto Setup: Refer to Auto Setup on page 47.
• Digital Bypass: The DHD Controller can either process 1080i digital sources or
pass them through to the projector. By default, it passes them through.
With a VX-44d/CineWide or VX-55d/CineWide, it may be necessary to instruct the
DHD Controller to process 1080i digital sources internally. To do this, select an input
other than HDMI
1 or HDMI 2 on the controller. Then, select Digital Bypass from the
Display Device menu and press ENTER to clear the checkbox.
