And that's the comparison problem JVC scales 1920 x 1080, to 3840 x 2160. A rather simple scale. Then it flashes the scaled component of that new resolution (lets call it 1920s x 1080s) separately after the original 1920 x 1080 frame, (let's call that 1920o x 1080o) is flashed. The 1920s x 1080s is e shifted over to put those pixels where they would belong on the screen if the JVC panel were 3840 x 2160. The scaling needed to be done to take 1080p to 4K (the Sony 4K panel) is much more complex horizontally. JVC's scaling is much easier. Physically shifted the new pixels generated by the scale so your eyes see them im the right place, is their licensed neat trick, E-shift.
