Sony SXRD panels - (LCoS)
A sort of short history of LCoS panels in projectors: It is true, that the largest percentage of home theater projectors use either DLP or 3LCD technology. Sony uses Liquid Crystal on Silicon, a reflective panel, as opposed to the translucent typical LCD panels. Sony calls their LCoS implementation SXRD. In the under $10,000 price range, JVC and Sony are the primary manufacturers of LCoS home theater projectors. with (in the US), LG making their move (they use Sony panels). We're finally seeing relatively affordable LCoS projectors, which is great news for all of us. Between Sony and LG, you now have a choice under $3000.
But let's concern ourselves now with the more expensive LCoS. The advantages of LCoS, these days, are twofold: First, LCoS panels have, for all practical purposes, invisible pixel structures, way below visibility at normal seating distances with a 1080p projector. Only the 3LCD Panasonic PT-AE4000, with its addition of their SmoothScreen technology, has less visible pixels, and it comes with a price - a slightly softer image.
Pixel visibility, and screen door effect are, effectively, non-issues with this Sony, thanks to the LCoS panels.
The second advantage, it seems, is in terms of black level performance. While some 3LCD and DLP projectors can match some of the LCoS projectors, at this point in time, the Sony, but more so, the JVC LCoS projectors, outperform almost most of the non LCoS competition, in black level performance. And The Sony's are pretty much comparable to all but one or two other brands in blacks.
Individual SXRD panel adjustment
A very nice touch, this Sony allows individual adjustment of each panel for more precise alignment. This feature carried forward from the HW10 and their older more expensive models too. This isn't an end all, there are still limits to the coarseness of the adjustments. If a panel is off 1/3 a pixel, that's too small to compensate for. By breaking the screen down into nine segments, it allows more precise results, than, for example, the single pixel shift design used in the JVC projectors and some others. It's a nice extra to have, although I have to think of it providing only minor benefit, at best.
