[1] 8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017.
To minimize the perceived flicker, projectors employed dual- and triple-blade shutters, so each frame was displayed two or three times, increasing the flicker rate to 48 or 72 hertz and reducing eye strain. Thomas Edison said that 46 frames per second was the minimum needed for the eye to perceive motion: "Anything less will strain the eye."
The flicker fusion threshold, also known as critical flicker frequency or flicker fusion rate, is the frequency at which a flickering light appears steady to the average human observer. It is a concept studied in vision science, more specifically in the psychophysics of visual perception. A traditional term for "flicker fusion" is "persistence ...

[45] [46] [47] In April 2012, Panasonic, in collaboration with NHK announced a 145 in (370 cm) display (7680 × 4320 at 60 fps), which has 33.2 million 0.417 mm square pixels. [48]
The human eye can perceive anywhere from 480 fps to 4000 fps, [dubious – discuss] [citation needed] and see it as looking completely realistic or immersive naturally. While 120 fps looks 'realistic', the stroboscopic look can still be seen, which also happens on 60 Hz monitors playing 60 fps video and sometimes excessive motion blur ...
Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. [1] [2] [3] It covers content creation, distribution, and playback.[1] [4] [5] [6] It includes dynamic metadata that define the aspect ratio and adjust the picture based on a display's capabilities on a per-shot or even per-frame basis, optimizing the presentation.
