Introduction

When the history of digital projection is written, October 2005 will stand out as a milestone. After numerous demonstrations, impassioned industry discussions and mounting anticipation, it was in October 2005 that the Sony SRX-R110 and SRX-R105 became the world's first commercially available 4K projectors, with deliveries to Landmark Theaters, the National Geographic Society and Sony Pictures Entertainment.

Since that time, Sony 4K projection has become a fixture in auditoriums, research universities, flight simulators, control rooms and trade shows as well as movie theaters. In short, Sony 4K is called on for any application that demands ultimate size, resolution and picture quality. And Sony has extended the product line, adding two models with a pre-installed DVI input (SRX-S110 and SRX- S105) and two dedicated Digital Cinema models (SRX-R220 and SRX-R210).

As with any such dramatic departure, Sony 4K projection raises many questions.

•Why has Sony entered the high-end digital projection market? Why has such a large company, so well known in other categories, decided to pursue such a niche?

•What is the significance of 4K (4096 x 2160) resolution? What source devices support 4K? What signal transport delivers 4K? What applications does 4K serve?

•What is the technology behind the projectors' microdisplay device: Sony's Silicon X-tal Reflective Display (SXRD™) panel? How does it perform, not simply in terms of resolution, but also the vital parameters of contrast, brightness, response time, aperture ratio and long-term stability?

•How do Sony 4K projectors work? How are they connected and controlled?

To begin to answer these questions, Sony has prepared this document. Here we will take a close look at the Sony 4K projectors for Visualization, Simulation, Auditoriums and Postproduction. These are the 100 Series projectors, the SRX-S110, S105, R110 and R105. (For detailed information on the Sony 4K projectors for Digital Cinema—the SRX-R220 and R210—please refer to sony.com/digitalcinema.)
