JDisplay

At present that 4K displays accept become more commonplace, we're seeing a scattering of manufacturers start pushing 8K resolutions. At CEATEC (Combined Exhibition of Advanced Technologies) this week, Japanese manufacturer J-Display will bear witness the starting time 8K monitor — a 17.iii-inch panel running at 7680×4320. That works out to nearly 520 PPI, which means the homo eye would be unable to distinguish pixels at merely vii inches. Given that most people find a seven-inch focus rather limiting, information technology means this display is going to be retina at any sane distance.

According to J-Display, the new 17.4-inch IPS console is built using LTPS (depression-temperature polysilicon). We've talked almost this technology in the past, and it's one of the nearly-avant-garde methods of edifice conventional LCDs — even better in some respects than Sharp'south IGZO. J-Display is also claiming a 120Hz refresh charge per unit, wide viewing angles, and plainly positioning the hardware every bit a video production display.

As Hot Hardware notes, at that place are some key points left unanswered in the current copy. Primary amongst them is what connection standard this monitor could perhaps be using to hit 8K resolutions at 120Hz. Correct now, the highest-bandwidth technology available in consumer hardware is HDMI 2.0, which is supported by Nvidia'due south loftier-end Maxwell cards. HDMI 2.0, however, maxes out at 4096×2160 at 60Hz. It might be possible to tweak the standard to let for 8K @ 30Hz, simply that's just 25% of the necessary bandwidth. HDMI has a dual-link standard, known as Type B, only I'one thousand not certain it's ever been employed in consumer hardware, and doubling up bandwidth would still only allow for 8K resolutions at 60Hz — one-half of what J-Display is claiming.

LG8K

LG demoed 8K earlier this year, but it takes huge amounts of zoom to make information technology noticeable.

Things aren't much clearer on the DisplayPort side of the fence, either. DisplayPort 1.three (non currently supported on whatever GPUs) allows for 8K @ 60Hz, just once more — no electric current manufacturer is shipping graphics cards that tin even support information technology. Of form, J-Display could be relying on a custom-built solution, similar Apple tree did with its 5K iMac, simply the need for such solutions points to how long information technology'southward going to exist earlier 8K panels actually go mainstream. J-Brandish obliquely alludes to this when they refer to the 4K/8K broadcasting that'south expected to be widespread in Japan by 2022, simply neglect to mention that it's 4K that's expected to become live to consumers. 8K will hopefully exist ready for the Olympics in 2022, simply in that location's no plan yet to roll the standard out to consumer hardware.

There's as well no mention of a toll tag, but we're willing to let that slide for at present. OLEDs and 4K panels were staples of the convention circuit years before they were ever bachelor for consumers to purchase, and nosotros expect to see 8K follow a similar pattern. Even if it was possible to buy an off-the-shelf GPU to drive this kind of panel, we uncertainty consumers would enjoy the experience very much.

WattsPer

Our contempo Fury Nano review showed how GPU power consumption (measured in the number of watts required to draw each frame) closely tracks the game's resolution. In each example, the amount of power required per frame of 4K was roughly 4x the ability requirement of 1080p. Quadruple the pixels and you quadruple the ability consumption. Extend that out to 8K, and nosotros'd exist looking at almost 80W of ability per frame. That's 9.6KW of system power required to drive an 8K panel at 120 FPS.

Information technology's going to be a fiddling while.
