Which signal can be connected ?

Standard S-Video(S-VHS)with separate Y(luma) and C (chroma) signals.

How to select the S-Videoinput ?

1.Press 4 on the RCU

Note: Another way for selecting this input is via the Menu.

The projector allows the input of more S-Videosignals (up to 3 composite video signals)."S-Video extended configuration", page 28

This note is not valid for the Pro version:

The Audio&Video optional layer(3) allows the use of an additional S-Videoinput (referred to asS-Video4).The selection of this optional input happens the same way as the standard input (key 4)

3.6Digital Visual Interface (DVI) input


Digital Visual Interface is a display interface developed in response to the proliferation of digital flat panel displays.

The digital video connectivity standard that was developed by DDWG (Digital Display Work Group). This connection standard offers two different connectors: one with 24 pins that handles digital video signals only, and one with 29 pins that handles both digital and analog video. This standard uses TMDS (Transition Minimized Differential Signal) from Silicon Image and DDC (Display Data Channel) from VESA (Video Electronics Standards Association).

DVI can be single or dual link.

Input specifications

Single link DVI

Differential input voltage: 200 mV - 800mV
