Repeated side-by-side shoot-outs viewed by experts have concluded you need to view a freeze-frame from 2 feet to see the difference between faux 4k and real 4k. There have been multiple threads on this and they come to the same conclusion....
Don't get me wrong I look forward to full 4k someday on my big screen but don't want pixel shift...unless my RS1 dies on me I will wait it out for now.
I'm not saying this to prove a point. I say this with a feeling of supporting your experience. I just don't want you missing out on spectacular technology for something that's not really visible.
In addition, with the angular resolution of the human eye, 4k doesn't add anything unless sitting closer than 1sw. Again... don't miss out!
