Samsung and 4K TVs were the stars of CES 2015
4K, also known as 4K ultra HD TV, is the next stage in television picture quality.
A 4K ultra HD TV picture is 3,840 x 2,160 pixels, more than 8 million pixels in total, which is four times the number in ‘normal’ high-definition (1,920 x 1,080).
In terms of trends, 4K TVs took the top spot with 15,912 tweets. This was ahead of wearables on 3,998 mentions. Sony’s new KD-65X9000C 4K TV, announced at the show, will run Google’s Android TV software and is just 0.2-inch thick. The firm boasted the TV set is slimmer than its smartphone.
