A Real Home Theater

摘要

Screen quality follows a simple rule: The larger the screen, the more pixels necessary to fill it. A high-def image is 1,920 by 1,080 pixels. On a 60-inch LCD TV, the image is flawless, but go any larger-say, 80 inches or a wall-sized projection-and the individual pixels become visible, degrading image quality. The Sony VPL-VW1000ES is the first home-theater projector to produce 4,096-by-2,160-pixel, or 4K, images, which allows it to produce pictures up to 200 inches across.
