Some said they thought the JVC had better ANSI contrast this year and there may be a reason for that, for the e-shift models. Here is info off of JVC's site:
“e-Shift is an innovative JVC technology that allows us to build a projector with 4 times the resolution using much of our existing infrastructure, keeping the projector small and affordable. For 2013, We've made significant upgrades to the original e-Shift—now called e-shift2—which include an all-new optical device, smarter Multiple Pixel Control technology, and improved enhancement and upscaling. All of this results in a picture with significantly improved contrast, and more natural color tones than on previous models. And best of all, with the DLA-RS4810, e-shift2 4K precision is now more affordable than ever.
Using e-shift, the original 1920 x 1080 signal is processed with a correlation detection algorithm to uncover detail that can be enhanced on a 4K display. With e-shift2, a much wider area is sampled—12 times as many pixels than previously—which results in improved edge transitions, zero aliasing and stair-stepping, and a significant increase in contrast in detailed areas. New sub pixels are generated based on this detection and a 3840 x 2160 frame is created and enhanced. Our new 8 band analysis filter delivers much more accurate smoothing and enhancement that the previous 2 band filter. The enhanced 4K frame is then temporally separated into subframes 1920 x 1080 pixels each and projected using a the D-ILA optical system through the e-Shift2 device. The original e-Shift device used liquid crystals to shift the subframes by 0.5 pixel both vertically and horizontally. Our new e-shift2 device shifts the image without the use of liquid crystals, and that results in an overall better resolution linearity and better ANSI contrast.
The result is an image with 4 times the pixel density of the original content.”
