If I'm not mistaken, since most (all?) rear projection microdisplays to this point have had fixed resolutions and refresh rates, they show information about the input
signal on the screen since the display output
signal is always the same. I think that it's exceedingly
unlikely that this display has multiple refresh rates (e.g. 24Hz, 30Hz, 60Hz, 120Hz, etc.) Since this is a 120Hz unit, the display most probably takes whatever input signal that it is given (that it accepts) and converts it to 120Hz- somehow.
Now I hope (and believe) that the A3000's take 24fps signals and multiply them directly to 120Hz (24 X 5 = 120) without further processing (other than maybe black frame insertion and perhaps Motionflow frame interpolation if you choose to use that feature). Some recent 120Hz displays don't do that, though. Instead- again if I'm not mistaken- they take the 24fps signal, convert it to 30Hz with 3:2 pulldown telecine, and then multiply it by 4 to bring it up to 120Hz. In my mind, this defeats most if not all of the purpose of having 24fps input on a 120Hz display (e.g. judder reduction). I do believe the A3000 does it "right", but don't know, and don't think that seeing a display of the input signal proves it does.
Now, having said that, if a LCoS display were to take a 24Hz signal and multiply it to 120Hz without any
further processing (no black frame insertion, no Motionflow, etc.) then the 5 repeats of each frame wouldn't change and you would have an effective
refresh rate of 24Hz (even though you still have a true refresh rate of 120Hz), but I think that unlikely.
