drag2share: JVC shows off projectors with 4K precision, but not quite 4K pixels

JVC first brought 4K home with its $175k DLA-RS4000 and now it's back with four new models with greater than HD resolution at much easier to swallow prices. You'll note the term used is "with 4K precision", because strictly speaking these don't project over 4,000 pixels of horizontal resolution, coming in at a still impressive 3,840 x 2,160 resolution. While this is still about four times the number of a standard HD image, it's less than say, Sony's VPL-VW1000ES. Filling in the difference is JVC's e-Shift technology, which was originally developed for its 8K projector. It works by creating two 1080p frames, with one shifted down diagonally and alternated at 120Hz to create the effect.

The scheme is not far off from the old wobulation technology featured in some "1080p" DLPs once upon a time, but this time there are no moving parts as it's all being done electronically. Shown off with an HD resolution source the upscaled image was still impressively sharp to us, even up close, while it also handles native 4K feed. While JVC may not be winning on raw pixel count, what it does have is a serious price advantage. Sony indicated its hardware would be available for "less than $25,000" but the top of the line JVC has an MSRP of just $12k, while the cheaper model will be $7,999 when they all ship in November. Check out the press release after the break and images in the gallery for details, including those so rarely seen native contrast ratio measurements.
