Hi I am new here and need some help. I have a Sony 1042 projector and a video scaler. I have a S-video cable going to the input of the scaler and a component video cable going to the projector from the scaler. The problem is that at the lowest resolution I get two pictures on my screen and at the highest resolution I get multiple pictures. There is a sync input on the scaler, am I supposed to have something hooked to that and if so, what does it hook up to?
