Small screen for 4K
Short of sitting very close, you’ll need a screen bigger than 55 inches to see the full benefits of 4K resolution. But the XBR-55X900B is, nevertheless, a champion in all respects, including one we didn’t anticipate: state-of-the-art edge-lit local dimming.
The XBR-55X900B is the smallest set in Sony’s X900B series, which also includes the 65-inch XBR-65X900B ($5,000) and the 79-inch XBR-79X900B ($9,000). Fifty-five inches is a relatively small size for achieving the maximum benefits of 4K resolution. But it’s also perhaps today’s most popular size for the principal home HDTV, so there’s no denying its market importance for Ultra HD as well.
