Samsung has a 60-inch 4K Ultra HD 3-D television, while both LG and Sony have 55-inch 4K 3-D TVs. All of these televisions come with Wi-Fi, smart functionality and LED backlight. Specialized 3-D glasses are necessary to view 3-D content.
The Sony XBR55X850C features the ability to upscale all content to a 4K resolution. It also displays better colors and greater realism due to its Triluminos technology. The Higher Dynamic Range feature results in a more realistic range of brightness levels. Customers can also use their remotes to activate the television's voice search feature.
As the Sony XBR55X850C is an Android TV, customers can access a number of streaming applications and Android games through it. The Google Play Store offers apps for YouTube, Netflix and other video streaming services. Google Cast allows broadcasting of apps or Web pages from Android phones, tablets, Windows computers and Chromebooks.
The resolution of 4K or ultra-high-definition televisions is 3840 x 2160 pixels, or twice that of 1080p high-definition TVs. This is different from the cinematic 4K resolution, which is 4096 x 2160p. While 4K content is still limited compared to 1080p, both Netflix and Amazon stream some of their original shows in 4K resolution.
