Ultra High-Def, Ultra Low Price

SOUND & VISION has reviewed a number of DLP projectors over the past two years that display 4K-resolution images with the help of Texas Instruments’ XPR pixel-shifting technology. Two of those models, from BenQ and Acer, are priced relatively high due to their use of laser light engines.
