What They Say
The 8K Association published some details on some new 8K/e-ShiftX that upgrades the firm’s e-Shift technology by doubling the number of image shifting positions for each frame to four. The projectors use three DCI-4K panels (4096 x 2160) that are driven at 240Hz to provide a DCI 8K (8192 x 4320) image at 60fps. The report said that “JVC employs an “e-ShiftX filter” that mechanically moves and shifts the 4 images at 240 Hz. It is a glass substrate between the optical block and the primary lens designed to bend the light as it moves”.
The projectors have dual 48Gbps HDMI 2.1 ports with 4K/120P content displayeded natively. There are three models from $15K to $25K wuth up to 3000 lumens. There is also an ‘entry level’ unut that has 2,200 lumens of output and uses older ‘two shift’ technology. It has 40,000:1 contrast (not dynamic) and costs $10K.
What We Think
JVC has also supplied systems using 8K native D-ILA chips, but, inevitably, given the size of the chips, they are very expensive. Not only are the chips big, but the larger area makes the optics more tricky, although moving around the 4 chips must be far from trivial. Chris Chinnock wrote this article and my comfort with pixel-shifted imagery was very influenced by his work in this area some years ago. Still, I have always liked LCOS projectors for movie content as they can have a real analogue/film look. (BR)
