2. Installation and Connections

￿Making Connections

NOTE: When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning on the power to the notebook PC. In most cases signal cannot be output from RGB output unless the notebook PC is turned on after connecting with the projector.

*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.

Connecting Your PC or Macintosh Computer

NOTE: • VT676/VT670/VT575/VT470: The COMPUTER 1 connector supports Plug & Play (DDC2).

• VT47: The COMPUTER connector supports Plug & Play (DDC2).
