First 8K computer monitor expected this week

Now that 4K displays have become more commonplace, we’re seeing a handful of manufacturers start pushing 8K resolutions. At CEATEC (Combined Exhibition of Advanced Technologies) this week, Japanese manufacturer J-Display will show the first 8K monitor — a 17.3-inch panel running at 7680×4320. That works out to nearly 520 PPI, which means the human eye would be unable to distinguish pixels at just seven inches. Given that most people find a seven-inch focus rather limiting, it means this display is going to be retina at any sane distance.
According to J-Display, the new 17.4-inch IPS panel is built using LTPS (low-temperature polysilicon). We’ve talked about this technology in the past, and it’s one of the most-advanced methods of building conventional LCDs — even better in some respects than Sharp’s IGZO. J-Display is also claiming a 120Hz refresh rate, wide viewing angles, and apparently positioning the hardware as a video production display.
As Hot Hardware notes, there are some key points left unanswered in the current copy. Chief among them is what connection standard this monitor could possibly be using to hit 8K resolutions at 120Hz. Right now, the highest-bandwidth technology available in consumer hardware is HDMI 2.0, which is supported by Nvidia’s high-end Maxwell cards. HDMI 2.0, however, maxes out at 4096×2160 at 60Hz. It might be possible to tweak the standard to allow for 8K @ 30Hz, but that’s just 25% of the necessary bandwidth. HDMI has a dual-link standard, known as Type B, but I’m not certain it’s ever been employed in consumer hardware, and doubling up bandwidth would still only allow for 8K resolutions at 60Hz — half of what J-Display is claiming.
