I say the above is theorethical because under ordinary circumstances digital zoom should be avoided at all cost comparitive to optical zoom.
But I believe my theory may prove true for the simple fact that the video displays on these digi-scopes are quite small and top out at resolutions which contain less pixels than full HD signals.
I could be flat wrong but the way I am looking at this is:
OLED screen for a unit at this price point can't be much higher than 800x600 pixels in resolution, so:
At 1x you are viewing an 800 x 600 pixel range of a sensor provided 1920 x 1080 source.
At 2x you are still viewing 800 x 600 pixels, because the viewing size doesn't change, however instead of strectching a lower quality source signal out your actually zooming into a higher quality source signal
So on and so forth throughout the zoom progression.
I wish somebody with a video engineering degree would come in here and say that I am right or wrong....
Or I'll just have to wait another 5 days, weeks, months to find out for myself
