> apparently due to OLEDs ultra-low response time, which produces zero fading between adjacent frames. (By the way, why didn't this happen with 35mm movie projectors? They couldn't blend adjacent frames either, because they are just shining light through individual pictures on a sheet of celluloid, yet I don't remember seeing this kind of stutter in movie theatres back in the day!

35 mm film projectors usually interrupt the light 3 times per frame, and switch frames while the light is interrupted. Some projectors only interrupt the light twice per frame, but I think those were earlier projectors. By your description, on an OLED the pixels just change to the new frame, with no transition. You might prefer an OLED with black frame insertion? (Although, I have an LCD with that and it gives me headaches)
