The 85in screen costs $134,104 and there is nothing you can watch on it.

Dubbed the LV-85001, the screen measures just over 7ft from corner to corner and has a contrast ratio of 100,000:1, plus a viewing angle of 176 degrees. It will go on sale next month Where regular HD has a resolution of 1920 x 1080, 8K measures in at 7680 x 4320.

The screen has a pixel density of 104 per inch. The 8K output requires the use of four USB 2.0 inputs, so it is already looking impractical for home use.

We admire those who want to stay ahead of the game, particularly when they are as broke as Sharp, but it might seem a little silly given that there are too few 4K broadcasts yet.

Sharp said it will flog its 8K TV to the business sector, letting companies produce their own 8K content to be displayed on it, rather than waiting for TV networks to broadcast in the super-high resolution.

The Japanese broadcaster NHK will begin testing 8K broadcasts in 2016 and hopes to have a full service up and running in time for the Tokyo 2020 Olympics.
