Anandtech published CEATIC 2016: Sharp Showcases 27-inch 8K 120Hz IGZO Monitor with HDR, also 1000 PPI for VR A quote from the article:

While we?re not CEATIC, a Japanese technology show, news has come via PC Watch regarding a new publicly announced milestone in monitor production. For any journalist that has attended either IFA, Computex, CES or MWC over the past year, it would be hard going to miss one of the super large (80-inch plus) 8K monitors doing the rounds. While highly impressive in their own right, current 8K displays on show typically have a low pixel-per-inch value in order to achieve a good panel off the production line. So despite the fact we can get 4K panels on smartphones (Sony Xperia Z5 Premium is 4K in 5.5-inch, or 806 PPI), expanding the size at that pixel density is difficult with panel yields. Also, moving 8K down to a monitor size has been hidden at the panel companies internal research divisions until now.

So this is where the Sharp monitor on display at CEATIC gets interesting. The IGZO display is down at 27-inches, marking a 326 PPI, just hitting at the door of large FHD smartphone displays. The panel is also listed at 1000 nit brightness. But to double down on specifications, the stand listed the display as supporting 120 Hz while in 8K mode, and also supporting High Dynamic Range, or HDR. This requires a large amount of data to be pumped into the display, and as a result a photograph of the rear shows eight separate DisplayPort cables being used in order to give the display the data it needs. 8K120 with HDR is no easy task, suggesting 7680x4320 at 10 bits per color channel (so 30-bit for RGB) at 120 times a second would suggest needing 120 gigabits per second of bandwidth at a minimum (or 15 GB/sec). Thats even before you discuss overhead, which will push that higher.
