5k,8k,10k what's the point

[buyit1986]

Can someone explain the point of displays with resolutions in excess of 4k/UHD when the average  human eye cannot discern the difference. I'm just curious about this

I've never seen higher than 1440p tbh, but I'm sure the difference between  4k and 8k would be noticeable to (almost) everyone. 

 

Would also depend on the screen size though, an 80inch 4k next to an 80inch 8k for example, there'd probably be quite a difference.

Those resolutions are useful to have a lot of high quality elements on screen at once without scaling, and higher resolutions are better for larger displays. Would you rather have a 70" 720p or 1080p display, or would you rather have a 70" 4k/5k display? You'd rather have the latter.

I've never seen a 8k display so I wouldn't know, if i ever get to see that I will keep this in mind thank you

Thank you for the insights I didn't think of it that way, I do know for content creators 8k cameras are useful for editing down to 4k for publication. I think a 8k display might be cool if it was displayed next to a 4k display and you could tell the difference.

I have seen an 8k TV in Japan; it was playing a demo video and was about 70"(?) in size.  From 15' away it looked the same as the 4ks next to it.  As I got closer it started to look more and more amazing; at 4' feet it was staggering!  However, why would you watch a 70" screen from 4'?

 

Personally, I would like to see the resolution race put on hold for a while and have the industry focus on quality instead (HDR10 and Dolby Vision becoming standards are a good start...).  Doesn't seem likely though, when people vote with their wallets they generally choose quantity over quality.

I think the 1st thing is for you to remove this notion that " the human eye can only XXX" be it FPS, detail level, peripheral sight etc etc.

Each person is different, as much as some people refuse to admit, just becouse they cant see somthing , doesnt mean som1 else cant, even if they think they have the best vision possible. As the old addage goes, " theres always a bigger fish", there will always be som1 with better sight that you.

 

ofc there will be point where no1 can tell the difference between 2 resolutions at a given size, but i assure you. 4k at any reasonable monitor or TV size, is no where near the maximum resolution in which people can notice a difference.

 

The difference in resolution is much easier to see when the image being shown is not processed in any way. As such, movies are not ideal as they have a good deal of motion blur introduced to smooth the 24 fps most run at.

A static native resolution image, say a 10k image, displayed on un-processed 4k,8k, and 10k displays will show a difference.

So....

30" Display

10k = 10240 x 5760 = 392 pixel per inch

8k = 7680 x 4320 = 294 pixels per inch

4k = 3840 x 2160 = 147 pixel per inch

 

Consider that mobile phones have way higher PPI, and people notice. The Samsung galaxy S8 has a 5.8inch display at 2960x1440, thats 568 PPI.

"yes but a mobile is used very close to your eyes" ... well. so is a 30" monitor, maybe not THAt close, but close enough for you to notice a difference between 147 PPi and 392 PPi

 

Hope this helps explain.

Thank you for your insights I now have an idea of how to look to see if I can personally tell a difference.
