Sharp has been pushing near-8K screens (7,680 x 4,320) since 2015, though its first models later that year boasting true 8K had a consumer-unfriendly $130,000 price tag. But the issue wasn't accuracy -- it was lack of content recorded at such a high resolution to actually enjoy on the fancy screens. Watching 4K content isn't much different whether you're watching on a 4K or an 8K screen.
Ergo, Sharp's announcement blitz today also introduced a company initiative called "8K Ecosystem" dedicated to refining the process and tech of shooting, editing, storing and broadcasting content in 8K. Sharp's new TVs won't make much of a splash if there isn't material that only their screens can show off, and there's very little 8K content in the wild.
It's the same chicken-egg problem that 4K faced at first, though some pressure from outside the industry could nudge 8K along. Japan's telecommunications ministry is pushing for production and broadcasting of 8K technology by next year to ensure systems are ready for the 2020 Tokyo Olympics, according to The Japan Times.
Sharp will start selling its 8K AQUOS TVs in China and Japan later this year. Then it will release AQUOS models as 8K monitors for release in Taiwan in February 2018 and Europe in March -- but no official plans for a US release. Sharp hasn't listed a price for these screens, but a source told the Nikkei Asian Review that they may start at 1 million yen (or about $9,000).
