I am running a Roadster S9 and two Roadster X5's. The S9 is the center projector in this 3 projector setup. I am experiencing a "smokey effect" in my projected image. I have been told it is from the arc lamp, however it is only on the S9 neither of the X5's have, nor has any other projector I have ever used. Does anyone have an idea what would be causing this?
