I honestly cannot see the point of an 8K resolution screen on a Smart 'Phone. Over 33 million pixels on a tiny screen - what is the advantage?I am looking forward to 8k and the innovations that occur along the way and expect it will not end.
I will enjoy having a couple 8k displays on the wall [eg Samsung Frame] at home with High Res art that reveal ever increasing detail as you get closer to the pictures. Some artists like Monet painted in a blurry fashion eg Stacks of Wheat (End of Summer), but would like to see people walk up to the screen and every paint stroke revealed. Some of the popular painting masters art is truly impressive when up close, which is hard to achieve in the art galleries due to the crowds. The idea that there is a an ideal static point to view the display [tv screen] from disappears with art as it tend to pull you closer.
Security Cameras, now I could have 16 in 1080 mode in one large screen, which is a bit much, but to have the main four of my 4k cameras on as display in their native format will be great, like windows showing me what is going on in the garden or with the animals. At the moment when doing this from another country there is an update lag. so the AI technology will be useful and force others to innovate. a lot of view in security camera is static a lot of the time when they are inside.
Next year by all accounts several phone makers will have high end models that are capable of 8k video on top of the 33mp+ photos that can be done; I do hope that the Samsung S11 will be 8k capable. Which is kind of ironic as just a few years ago I was lugging around a large camera and might again as like the Nikon Z7. But is you want to see example Nikon Z7 45mp picture here is an example Nikon Z 14-30mm F4 S real-world samples
So for the people that want to make their own content, the 8k future looks exciting. Storage wise I might need to upgrade my 8 bay NAS unless the new codec also makes file sizes smaller...
