The IFA Show is currently on in Berlin - This is the worlds leading trade show for consumer electronics and electrical goods, and is now in its 10th year.

Sony has announced three new projectors at the show, all featuring 4k (resolution of 4096x2160 pixels) displays and HDR (High Dynamic Range imaging).

There are three offerings from Sonys 4k line all of which feature Sony's SXRD Technology.  This technology is also sometimes referred to as LCOS (Liquid Crystal on Silicone) or as D-ILA (when JVC touts it).  Here's what Sony say about SXRD - 

Basically as per the wikipedia page ; Liquid crystal on silicon (LCoS or LCOS) is a miniaturized reflective active-matrix liquid-crystal display or "microdisplay" using a liquid crystal layer on top of a silicon backplane. Effectively light is blocked from passing through the LCD when blacks are meant to be shown.

The VPL-VW870ES ($35,000/€25,000) is Sony’s premium offering, with 2,200 lumens brightness and an 18-piece All Range Crisp Focus lens said to ensure high precision within a compact and lightweight design. Its Digital Focus Optimiser further provides refined image quality and accurate focus without distortion.

Sony have provided their 4k Motionflow technology in all of the new projectors, enabling smoother and clear motion by adding extra frames to reduce blur and maintain brightness.  They also offer up HDMI 18 Gbps compatibility and 4K 60P 10bit processing, and Reality Creation analyzing each element of an image to provide gamers with enhanced clarity and resolution without noise.

In the middle of the range sits the 1,800-lumens VPL-VQ570ES ($10,000/€8000), which features Picture Position Memory to quickly change settings for ideal format as well as high dynamic contrast by Advanced Iris, while the VPL-VW270ES ($5000/€5000) brings a 4K HDR picture at the company’s most affordable price point yet.
