4K televisions have a greater adoption rate than HDTV, according to technology lobby group the Consumer Technology Association (CTA). Sales of 4K televisions in the US are expected to double to 15m units this year; rising to 20m a year in 2017 and 26m in 2019.
“Consumers are showing a strong preference for 4K,” said Gary Shapiro, CEO of the CTA. "It's faster and more robust than HDTV," he explained, in comments reported by VentureBeat.
4K resolution is 4096 x 2160 pixels (or 3840 x 2160 on a 16:9 picture format), or four times the total number of pixels on a Full HD 1080p screen (1920 x 1080).
The price of televisions is also dropping: from an average of $1048 (£800) in 2015 to $861 (£650) in 2016. So far, there have been 700,000 4K Blu-ray players sold in 2016, with 500,000 4K Blu-ray discs sold, according to the Digital Entertainment Group.
But while 4K might be the highest resolution available in Europe and the US, Japan is set to broadcast 8K content in 2020 during the Tokyo Olympic Games. Sony and Panasonic are rumoured to be in the process of manufacturing televisions capable of supporting the increase in pixels.
