As I understand it, if the DMD is switched off, the mirrors are in the flat state (0 degrees tilt). If the DMD is switched on, the mirrors can be on or off (+/- 12 degrees tilt). My question is: is it possible to assign mirrors to be in the flat state when the DMD is switched on? If so, how do you do it? If it's not possible with the DLP4500, is there any other DMD with which it is possible?
