Making Connections; Enabling The Computer's External Display; Connecting Your Pc Or Macintosh Computer - NEC VT490 User Manual

Making Connections

NOTE: When using with a notebook PC, be sure to connect the projector and notebook PC while the projector is in standby mode
and before turning on the power to the notebook PC.
In most cases the output signal from the notebook PC is not turned on unless connected to the projector before being powered
up.
* If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power
management software.

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.

NOTE: An image may not be displayed correctly when a Video or S-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.
