JDisplay

Now that 4K displays accept become more than commonplace, we're seeing a handful of manufacturers start pushing 8K resolutions. At CEATEC (Combined Exhibition of Advanced Technologies) this calendar 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 ways 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 ways this display is going to be retina at any sane distance.

According to J-Brandish, 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 Precipitous'south IGZO. J-Display is as well challenge a 120Hz refresh rate, broad viewing angles, and apparently positioning the hardware as a video production display.

As Hot Hardware notes, there are some cardinal points left unanswered in the current re-create. Chief among them is what connectedness standard this monitor could perchance be using to hit 8K resolutions at 120Hz. Correct now, the highest-bandwidth technology available in consumer hardware is HDMI two.0, which is supported by Nvidia'due south high-finish Maxwell cards. HDMI ii.0, withal, maxes out at 4096×2160 at 60Hz. It might exist possible to tweak the standard to let for 8K @ 30Hz, but that's merely 25% of the necessary bandwidth. HDMI has a dual-link standard, known every bit Type B, only I'k non certain it's ever been employed in consumer hardware, and doubling upwards bandwidth would still just allow for 8K resolutions at 60Hz — one-half of what J-Display is claiming.

LG8K

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

Things aren't much clearer on the DisplayPort side of the fence, either. DisplayPort 1.3 (not currently supported on any GPUs) allows for 8K @ 60Hz, but over again — no current manufacturer is shipping graphics cards that can even support it. Of course, J-Display could be relying on a custom-built solution, similar Apple did with its 5K iMac, but the need for such solutions points to how long information technology's going to exist before 8K panels actually go mainstream. J-Brandish obliquely alludes to this when they refer to the 4K/8K dissemination that's expected to be widespread in Japan by 2018, but neglect to mention that information technology's 4K that's expected to get live to consumers. 8K will hopefully be prepare for the Olympics in 2020, but at that place's no program nevertheless to scroll the standard out to consumer hardware.

At that place'south also no mention of a toll tag, but nosotros're willing to permit that slide for now. OLEDs and 4K panels were staples of the convention excursion years before they were always bachelor for consumers to purchase, and nosotros look to encounter 8K follow a similar blueprint. Fifty-fifty if information technology was possible to buy an off-the-shelf GPU to bulldoze this kind of console, nosotros doubt consumers would enjoy the experience very much.

WattsPer

Our recent 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 instance, the amount of power required per frame of 4K was roughly 4x the power requirement of 1080p. Quadruple the pixels and you quadruple the ability consumption. Extend that out to 8K, and we'd be looking at nigh 80W of power per frame. That'south 9.6KW of system power required to drive an 8K panel at 120 FPS.

Information technology'due south going to be a little while.
