I received my sensor with no instructions so I went to dilard.com and looked up the tips and still am confused on what to do, first it mentions to mount the sensor 7 ' away directly lined up with the lens, well my projector is mounted on a wall inverted, with the lens center 14" from the ceiling, do I mount the sensor the same or what? it also mentions so have the shadow of the sensor in the middle of the screen. I am using a 16x9 screen running threw a quadscan scaler. anything special I should do their, should I bypass it? I noticed someone ran their projector full zoom, before running the setup is this something you should do? I hate calling and bother Mark H. but what the heck, how about some drawing on what it should look like when the sensor is set up correctly. I hate to start not really knowing what the correct procedure is? HELP!
