> Watching movies on OLED (or at least on this particular OLED) looks crap, because if you turn motion interpolation OFF, the image looks stuttery, 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!) And turning motion interpolation up a notch already produces the well-known soap opera effect. No, thanks.
My guess would be that it's not so much a difference between projectors and OLEDs as it is a difference between old movies and new movies.
Personally I think that slow pixels is the wrong way to "fix" poor motion blur in movies.
