LG Gets Ready for 8K Quad UHD
And we say, not even in ten years it will reach the consumer market. LG is carefully pushing 8K Quad Ultra HD display technology, or is warming us up for it. 8K Quad Ultra HD will get a 7680 x 4320 pixels native resolution which is sixteen times your Full HF telly.
Since Japanese engineers first demonstrated high-resolution at the International Television Engineers Conference in 1981, the demand for high-quality content has continued to grow. The high-resolution display trend has already begun with Full-HD TVs being commonplace in homes and QHD (Quad High Definition) quality panels being adopted in smartphones with screens that are the size of the palm a person’s hand. The high-resolution contents that provide realistic images and a true sense of immersion have now moved beyond 4K and the focus has now turned to super-high-resolution 8K.
The World is Turning to 8K
It is not difficult to hear the call for bigger and clearer images from everywhere around the world. When the BBC took on the broadcasting of the 2012 Olympics, they said, ‘Since 8K resolution is the highest resolution that the human eye is capable of seeing, it will put an end to the resolution discussion,’ predicting that ‘ultimately, 8K images will overtake the market.’
It has become clear that Japan is planning to launch an 8K SHV test broadcast and then promptly restructure the UHD service. Apple has also announced that they will release the ‘iMac 8K’ with a super-high resolution display later this year. Korea is also preparing to offer an 8K service demonstration at the 2018 Pyeongchang Winter Olympics. LG Display displayed a new beacon of the 8K era by revealing their 98-inch 8K Color Prime Ultra HDTV at CES 2015.
The Resolution and Pixels of 8K
How will 8K improve image quality over what we are already experiencing? Let’s take a closer look through resolution which is used as the concept to explain image quality.
The screen depicted in the image above is a 7,680 x 4,320 resolution screen. It is 2 times the resolution of a 4K screen but in actuality, the number of pixels is 4 times that of 4K which is 16 times more than Full HD. But what is the correlation between resolution and pixels? In short, by increasing the number of pixels on a screen, the viewer can enjoy a clearer picture.
For example, a 5-inch HD resolution smartphone screen with 900,000 pixels boasts higher image quality than a 5-inch SD resolution smartphone screen with 340,000 pixels. Likewise, FHD (1,920×1,080) provides clearer image than HD, and resolution continues to increase with QHD (3,840×2,160) and UHD (4,096×2,160). PPI (Pixel per Inch) is a term used to describe how many pixels are in an inch of screen and also represents the density of pixels. In order to increase the size of a display while maintaining the same resolution, the PPI must also be increased.
LG Display, Preparing for the 8K Era
LG Display has already succeeded in making super-high resolution a reality with the revealing of their 98-inch 8K UHD display at CES 2015. LG Display managed to improve the brightness of its 55-inch 8K UHD panel with 7,680×4320 resolution and 500nit by implementing M+ panel technology, which adds a white pixel to the existing RGB sub-pixel structure. IPS technology was also applied to make an impressive panel that has the advantage of high resolution and a wide viewing angle even on large scale screens.
With these developments, LG Display has expanded the Ultra-HD (UHD) lineup and is showing off diverse range of screen sizes with super-high resolution displays such as 8K. There are also high expectations in the commercial signage market as there is a need for clear large-scale high resolution screens. Look for great strides to be made by LG Display in the super-high resolution display era.

That link is absolute garbage and a half. It concludes that roughly 30fps, according to some questionable study done at ultra-low resolution in 2006, is good enough for FPS games. What a joke, the feeling between 60fps and 120 is night and day, especially in fighting games and FPS games. And yes I know fighting games are typically capped at 60fps. Not just feeling, obvious visual information is there, you can visibly see more frames super clearly such as when a character turns.
Even in something as lag-infested (super high ping, no eastern server) as League of Legends benefits from high frame rates. Character movement looks choppy at 60fps versus 200+, especially turning.
60fps is the absolute minimum, and that crap tries to conclude that 30 is fine for humans. Maybe 90 year old ones with serious degenerative problems, but I can perfectly consistently time my responses to 1 frame at 60fps both now that I have 20-30ms total lag and before when I had close to zero. I can see individual frames just fine at a rate of 60 and I'm not even young.
It is, and it is not. They took many studies and showed their conclusions. While one concluded that human eye nerves are quite insensitive to flicker over 60Hz, they have there part (which most of as know to be true) with rotary RGB filters in DLP projectors. Which is proof that you can actually perceive difference even for stuff running at 300 fps.

That article concluded 30fps is fine. Therefore the article is garbage.

Remarkably what technology offers today. Only that you barely get any 1080p source material these days (besides PC gaming of course), so why bother with 4K TVs, let alone 8K TVs?
This all reads like the technology is there, but there's little way to use it.
+1 on this and your source quote. Has anyone seen 4K in action beside a really good OLCD? Most demos of 4K involve static images with very little movement (think maybe a boat on the water in front of a city scene, or a person walking in a garden). When 4K is in motion and the viewer gets immersed in the subject matter your eyes quickly adjust and any visible gains are quickly forgotten (filtered). 4K, or 8K for that matter DOES look sharper and more detailed on larger displays, even in motion but for the average display being 46" I'd rather get me an OLED.
Anyone who claims there is a noticeable difference on the cellphone/tablets need to consider that it is their brain telling them it's better as the human eye cannot see that fine of detail on such a small display.

while it's nice that there's progress being made, I think 8k is useless outside the cinemas right now. I think that 4k TV's are useless for that matter until you start moving up to a 80 inch screen or bigger. My cable provider has yet to move up from 720P/1080i to full HD.
That being Said, I've just registered to guru3d after years of being a passive reader of the comment section to announce that I just ordered a 28inch 4k monitor!

I explained why people though that 60Hz crt were close to "flicker free" (they used artificial pixel light persistence).
