I went home this weekend and tried my flat monitor. I noticed in invert mode there seems to be a line on one side, the right = side of the array. Not sure if it has to do with threshold or what. I'm thinking of sending the lens and optacon up to Richard Ohm to at = least find out what it is capapble of doing interms of reading a = computer monitor.

Are you the one who reads an oscilloscope screen with the optacon? How do you stop that tactile jitter which I assume is the refresh rate of the scope screen?
