@zoyd, what problem do you foresee if I leave my setting the way it is now, even if a few and 'infrequent' pink sparkles appear in the scrolling pattern?
I finalized my setting last night (no more pink sparkles showed up on scrolling pattern and dither on black image). I then continued observation/testing today and after several cycles on scrolling pattern, I decided to close the back. Lo and behold, after putting back all screws, putting back all cables, testing the connections, and playing the scrolling pattern, a saw a few pink sparkles, but this showed up for only a short while. I kept replaying the scrolling pattern and saw it only once or twice. Are these sparkles probably more predominant when the unit is still cold? How safe/advisable it is to leave it this way? Or should I re-open and readjust?
FWIW, an observation for those about to setup this tweak, I observed the pink sparkles appeared more when set to Dynamic than Movie.
