Sony, JVC and Texas Instruments were among those touting 4K Ultra HD devices and content at the recent CEDIA 2015 Expo. Sony debuted its line of Full HD home theater projectors, including a 4K Ultra HD front projector with a laser light engine. JVC showcased its fourth-gen “near-native” 4K Ultra HD liquid-crystal-on-silicon (LCoS) tech for three projectors, “supporting some of the industry’s best contrast ratios and brightness levels in front projection,” according to HD Guru. Meanwhile, Texas Instruments announced a home-based 4K DLP chip for future front projectors. Manufacturers say affordable 4K home projectors should be available for demo around CES time in January.
