"8k" name in this case is just a marketing. It's not 8k, it's 4230p only.

8k is 7680×4320. 4k is 3840x2160.

Nope, That TV is 4320p (presumably 4320x7680) "4k" means ~2000x4000 pixels and "8k" means ~4000x8000 pixels. It is 8k and reasonably priced at $1000 new / $752.99 used

  No, 4k === 3840x2160 resolution.

    ...and 3840x2160 is roughly 4000x2000, thus "4K". It's close enough for the marketing department, and now that's what it's understood to mean.

    Originally 4K came from the DCI spec for digital cinema and it was 4096x2160. For consumer use it was shrinked to UHD which is the 3840x2160, but cinemas still use 4K (although most of the screens actually use 2K) Now 4K refers to image roughly the width of 4000 pixels according to wikipedia [1] [1] https://en.m.wikipedia.org/wiki/4K_resolution https://en.m.wikipedia.org/wiki/4K_resolution

      All new/upgraded auditoriums installed 4K (laser) projectors when I left the business 5 years ago. So not sure if most auditoriums only have 2K these days?

        IMAX has only started switching to 4K laser projectors a few years ago, they were one of the last hold outs for 2K projectors (and many IMAX cinemas still use 2K projectors sadly).

        Are those cinema projectors or more like video projectors? The cinema ones are more heavy duty and not changed so often.

        Cinema projectors. It should be said that I worked in the business in Norway which had converted all auditoriums to digital in 2010, so many theatres were looking at upgrading their projectors around the time I left for something else.

8k is double the vertical and horizontal resolution of 4k. You can argue that 4k was deceptive, since it switched from measuring the vertical resolution (2160p) to the horizontal, but 8k is just sticking with the established standards.

  4k was the marketers cashing in a puffery token they'd been carrying for quite a long time by accurately measuring the short side of displays. They moved to measuring the long side AND exaggerating by rounding up in the same generation, stealing the name of a slightly-better existing standard in the process. You're right that 8k makes sense so long as you accept 4k, though.

  Well, 4K is called that because when 1080p became common at home, cinemas switched to DCI 4K and suddenly TV manufacturers had to compete with that, so they branded the closest they could get to DCI 4K as their own "UHD 4K".

"8k" name in this case is just a marketing. It's not 8k, it's 4230p only.
