Summary: 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.
Pros: Exceptional blacks and shadow detail, Excellent color and resolution, Impressive sound with optional subwoofer
Excerpt: The standout features of the 55X900B are 1) the X-tended Dynamic Range feature which allows for more active zone control of the LED backlighting and 2) the Side Mounted speakers eliminate the need for a surround sound system.
Conclusion: We’re astonished the X900B isn’t Sony’s flagship television … it certainly looks and sounds the part. That this television is able to achieve such excellent black levels and avoid so many edge-lighting pitfalls is a testament to Sony’s engineering chops.
