7. Installation and Connections

NOTE: The projector is not compatible with video decoded outputs of the NEC ISS-6020 switcher.

NOTE: An image may not be displayed correctly when a Video source is played back via a commercially available scan converter.

This is because the projector will process a video signal as a computer signal at the default setting. In that case, do the following.

* When an image is displayed with the lower and upper black portion of the screen or a dark image is not displayed correctly:

Project an image to ﬁll the screen and then press the AUTO ADJ. button on the remote control or the projector cabinet.

Enabling the computer’s external display

Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector.

When using a PC compatible laptop, a combination of function keys will enable/disable the external display.

Usually, the combination of the “Fn” key along with one of the 12 function keys gets the external display to come on or off. For example, NEC

laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle through external display selections.

Cautions when using a DVI signal

• When the computer has a DVI output terminal, use a commercially available converter cable to connect the com-

puter to the projector’s HDMI 1 or HDMI 2 input terminal (only digital video signals can be input).

NOTE: When Viewing a DVI Digital Signal

• Turn off the power of the computer and projector before connecting.

• When a video deck is connected via a scan converter, etc., the display may not be correct during fast-forwarding and rewinding.

• Use a DVI-to-HDMI cable compliant with DDWG (Digital Display Working Group) DVI (Digital Visual Interface) revision 1.0 standard.

The cable should be within 197"/5 m long.

• Turn off the projector and the PC before connecting the DVI-to-HDMI cable.

• To project a DVI digital signal: Connect the cables, turn the projector on, then select the HDMI input. Finally, turn on your PC.

Failure to do so may not activate the digital output of the graphics card resulting in no picture being displayed. Should this happen, restart

your PC.

• Do not disconnect the DVI-to-HDMI cable while the projector is running. If the signal cable has been disconnected and then reconnected,

an image may not be correctly displayed. Should this happen, restart your PC.

• The COMPUTER video input terminals support Windows Plug and Play.

• A Mac signal adapter (commercially available) may be required to connect a Mac computer.
