Sharp Demonstrates 31.5-Inch 8K 120Hz HDR Monitor
Sharp this week demonstrated its first 31.5-inch HDR display featuring a 7680×4320 resolution and a 120 Hz refresh rate. The monitor uses the company's IGZO technology and the manufacturer evaluates plans to release this LCD commercially.
Being one of the key backers of an 8K resolution as well as the Super Hi-Vision format, Sharp was among the first to release 8K screens and 8K cameras for professionals as well as 8K UHD TVs for consumers. Several years ago, Sharp demonstrated its first 27-inch 8K IGZO monitor with a 120 Hz refresh rate and 1000 nits luminance, but the device has never been released commercially (at least, it has not been available in stores). This week the company showcased another 8Kp120 display.
Meanwhile, Sony has created a monstrous 783-inch display:
The screen is 19.2 meters (63 feet) long and 5.4 meters (17 feet) high, it features a diagonal of 783 inches and is generally larger than a bus. Sony does not disclose exact resolution of the display (other than saying that it has around 16,000 horizontal pixels), though judging by the looks of the screen we are dealing with something that has a non-standard resolution and a non-standard aspect ratio.
Sony's 16K 783-inch screen uses the company's Crystal LED technology that uses multiple Micro LED-based modules to build custom displays featuring virtually any size, any resolution, and any aspect ratio. Featuring individually-controlled Micro LEDs, the modules have no bezels and can be attached to each other seamlessly. Sony and Samsung use Micro LED/direct-lit LED-based modules to build custom screens for cinemas, airports, showrooms, and other venues that need large displays.

A New Wave of 8K TVs is Coming

No really. 8k at just over 30" would require you to be mere inches from it to actually appreciate the resolution, and then only in a small field due to how the fovea works. Why would anyone develop an 8k screen at this size?
I have a 2560*1440 resolution monitor at 30". There is no need to have more information density than this, it's already pushing the limit.

Well physicsmajor, lets not give up on reality so quickly; with rudimentary experimentation, you can easily see that the square sources arranged in a cartesian grid as is (typical of LCD pixels) do not fit with the models used for naturally emitted gaussian distributions (usually borrowed from film photography). Try opening paint or etc. and drawing a single pixel line across the screen with a slight angle, such that one or more shifts in pixel row (jaggies) are visible. Now walk away from the screen until you can no longer resolve the jaggies. Measure this distance. Now compare with the value arrived at with your preferred formulae for human resolving power. You will find that your measured distance is easily more than 3x greater than the calculated "retina resolution" distance.
I had a 30" 2560x1440 monitor for a decade, and I recently changed to a 28" 4k. The difference is appreciable, but with fine lines jaggies are still readily visible at 10 ft, and my eyes aren't great. I print native resolution fractal images at 600 pixels per inch and jaggies are still resolvable from more than a foot, despite the advantage of round ink drops (but there's also a disadvantage of screening due to halftoning). As long as the pixels remain square and gridlocked, there are gains to be had in a few more doublings... not the smartest approach, but brute force also gets there eventually.
