A human with 20/20 vision can differentiate up to 160 pixels (80 intensity pairs) per degree of field of view. It’s possible to see the difference between 4K and 8K video, but depends on the size of the display and the distance from the viewer.
The human horizontal field of view (HFOV) is about 175 degrees.
 To make the pixels disappear - have more than 160 pixels per degree of field of view - a 4K monitor needs to fill less than 24 degrees HFOV (14%), and an 8K monitor less than 48 degrees (28%). Those numbers aren’t very big.
If you wanted to have a head-mounted display fill 100% of your HFOV at 160 pixels per degree the resolution would need to be 28K.

For gaming for example,If we get to a display resolution of about 8k horizontally and about 6k vertically then, for a player with 20/20 vision, they will have something that is close to perfect for their visual system.”
(*Beyond that, the human eye wouldn’t be able to perceive any more detail on their screen. There’ll be no great race to 16K or 32K.)
So..the difference between 1080p,4K,8K is really one of fine detail and sitting at the correct viewing distance to perceive that detail-this is where the science of setup and calculating viewing distances are ALL important to ensure that you have the correct information to get the best out of your display. 8K image....
Where 8K images will come into their own of course is where your left and right peripheral vision are not occupied by anything other than the image..the IMMERSIVE 360 technique...that Projectiondreams have employed in their setup for some years now.

In short ABOVE 65" tv`s and assuming you want to ensure that the experience is optimal, I would suggest 8K..... not buy an 8K display IF you are further back beyond a point where your peripheral vision is not occupied.
