On E3 2017, 4K was the biggest buzzwords. So what is “K”, and why do four of them make a better picture?
The” K” in 4K is taken from the prefix kilo-, meaning “thousand,” which comes to English from French. “K” is often used where typing out “thousand”, in addition: “Crowdfunding Raised $500K” or “I’ve reached 50K subscriber”.
In 4K resolution, “K” is more of a marketing ploy than a real number. It represent 3840×2160 pixels, which is one of the higher resolutions available in consumer electronics. Marketers call this resolution 4K because it’s almost four thousand pixels across, because it sounds more impressive than “3.84K”.
