At CEDIA in 2011 with 3D being passe, the new big thing was set to be 4K. Sony presented the first true 4K projector for consumers, and JVC come out with eShift to compete with that. What eShift does is take the 1920×1080 pixel array and shift it in two directions by half a pixel, to enable for something that approximates 4K resolution, but isn’t actually a true 4K display.
Though not true 4K, this still allows for better pixel fill, but more importantly also allows for very exact pixel alignment on the screen. Since JVC projectors have always been class leaders in black level and contrast ratio, adding in even better sharpness only helps them out. Does eShift bring a lot to the table, or is it really a place holder until we get to true 4K resolution? I have a full JVC X70 Review at Secrets of Home Theater which goes into depth with the projector to see what eShift does and how the projector performs overall.
