I have an inspiron 1100 with an s-video output port. I have plugged a cable into the output of the inspiron 1100 into the input port of an Infocus IN72 projector. I cannot get the unit to send a signal from the computer screen to the projector. I have downloaded and installed version A32 of the Bios driver and version 184.108.40.20642 Video driver. I have tried to shift screens using the FN +F8 to no avail. Can someone help me to switch from the laptop screen to the projector?
