connecting projector to PC problem shadym[ at ]gmail.com 28.09.2006 21:32:21 Hi guys I have a Benq MP610 Projector its a good projector I guess I bought it to be used in a computer lab in a school for demonstration purposes my problem is I want the monitor of the computer which the projector is connected to work with the projector because they are using this computer for lessons which doesn't need projector also and here is what I've tried so far: - connecting an AGP VGA card to the computer (Didn't work) Reason: my computer have a built-in VGA card and a free AGP slot when the AGP card is connected the internal VGA will be disconnect automatically from bios with no control over this feature to turn it off. - connecting the projector with computer and using the VGA out port from the projector to the computer screen (Didn't work) Reason: to use the out port on the projector I bought a female/female cable to connect my monitor to the out port of the projector its making my monitor showing curly moving lines passing horizontally across the screen "maybe bad quality cables or something", and most importantly when I turn off the projector the computer monitor will be turned off as well which make the computer of no use to the other lessons with no projector. I am using windows XP Pro., my screen refresh rate is set to 60Hz the VGA to Projector cable length is 5m and the female/female cable to the monitor length is 3m. What I am thinking about now is to buy a "monitor switch" if it exist I don't know!! to out put from the computer to the monitor and the projector and switch between them. Any comments will be greatly appreciated, thanks for your time.

It sounds like you just need a "VGA video splitter" to split the signal from the computer into the monitor and projector. You just need 2-port output with a signal amplifier. These are common devices that you can find in most computer stores. The ones at CompUSA start at $54: http://tinyurl.com/p2ehl
