CES 2017: The top trends in new TVs

"UHD, also known as 4K for its almost 4,000 pixels of horizontal resolution, offers a much finer picture than mere HDTV. But unless you get a screen larger than 55 inches or so, the additional detail will vanish when viewed from across the room.

An upgrade to UHD called HDR, short for “high dynamic range,” provides a discernable difference even on smaller displays: a wider range of colors. The difference is obvious, especially with scenes like sunsets and sunrises that involve a large degree of contrast.

HDR stopped being a niche variation of UHD at last year’s CES but still came at a price premium. At this year’s show, the HDR tax looks set to shrivel. Most vendors aren’t talking prices yet, but the Chinese vendor TCL — a leading supplier of TVs with built-in Roku media-player software — said it will sell a 50-inch UHD HDR set for $500."
