Best of the Best 2013: Electronics: Video: Sony XBR-84X900

The Sony XBR-84X900 (www.sony​.com) was among the first TVs to offer playback of 4K video content—and it is still the best. Priced at $25,000, the 84-inch TV, which uses an edge-lit array of LEDs to backlight the LCD picture, is capable of delivering full 1080p resolution images to each eye during playback of 3-D content. Sony equips the set with a newly developed chip that upscales and refines the resolution of any content less than 4K. For the XBR-84X900, which weighs 176 pounds and has a depth of about 3.5 inches, the company offers prepurchase in-home consultation and white-glove installation.
