4K vs. 8K TV

4K, or 3840×2160, is about 2 million pixels and it contains almost four times the number of pixels on a screen compared with 1080P (current) technology.
8K resolution is 7680×4320 pixels. It is 16 times more dense than 4K. The numbers show 4K at 2 million pixels is compared to 8K at 33 million pixels. Today’s TV technology is not yet capable of handling this kind of raw power.
Other comparisons show current HD is 24 frames per second, 4K ultra HD is 60 frames per second, and 8K super Hi Vision is 120 frames per second.
For human eyes to actually differentiate between 4K and 8K resolutions, 8K televisions need to be at least 70 and 80 inches in size and you need to sit very close. To truly enjoy 8K, the television sets need to be even larger than that. Panasonic has developed a plasma television that is 145 inches.
2020 Olympics will all be broadcast in 8K - Samsung, LG, Sony, and Panasonic have all announced plans to have 8K TVs ready for the 2020 Tokyo Olympics.

Incidentally, as of September 2017 an 85 inch 8K TV costs $133,000 and is only available in Japan. Oh, and the old wives tale of sitting too close can hurt your eyes is a myth.

We do not even have much content for 4K TVs and now Sharp has announced an 8K, 85 inch LV-85001 for just US $133,000. In fact broadcast testing of 8K is not scheduled to begin until 2016.

8K is 7680 x 4320, which is 104 pixels per inch at the 85-inch size; the contrast ratio is 100,000:1 with viewing angles of 176 degrees. It will be available October 31, 2015.

When I first got into the technology business, hardware was always lagging behind need. Seems during the past ten years technology is leading, and searching for content and relevance before its typically ultra-short life cycle ends. Thank goodness for early adopters, who take the arrows and pay the big bucks so we can enjoy later.
