I just inherited a M500 projector from my cousin who had to move away and I've been trying to get it to accept video signal from either composite video cable (yellow tip), S-Video or HDMI via different converter pieces for the DVI-I port. I haven't been successful. I've looked everywhere for a converter piece that would allow the projector to accept this type of video signal but no luck. I finally went to an electronics shop where the guy told me that there were specific cables that come with the projector that allow for this type of conversion and that I need these specifically. Since my cousin is gone I won't be getting them from him. Can anyone PLEASE help me by directing me to where I might find these cables or if I can purchase them directly from Lenovo??????? I can't wait to get this projector up and running.
