I recently got the projector off of EBay in hopes of being able to hook an HDMI up to it and use an adapter to successfully connect it to the projector. Projector inputs are as follows: Red/white/yellow, s-video, (2) VGA inputs, and rs-232. I bought a 20ft HDMI cable, HDMI to dvi adapter, and then Dvi to VGA adapter, and then connected it to the projector. I cannot get it to produce a signal to the projector. Can someone tell me what I need to make this work? Thank you in advance.
