OK, not really. But the day will come when 4K goes the way of all those lower resolutions and gets replaced by a bigger number, in this case 8K. According to reports, in fact, Samsung is unveiling a series of 8K TVs that you'll be able to buy this year. 

We've seen concept 8K TVs for years, but this would be the first you could actually buy. If Samsung's TV hits the market this year, it will almost certainly usher in 8K sets from other manufacturers in 2019 and beyond. Now that the age of 8K TVs is almost upon us, you might have some questions.
