You Don’t See In 4k

Well, the picture looks better on my 4K TV than it did on my 1080p, so ... human eyes may not "see in 4K," but I can see the difference between 4K and 1080p.

I didn't watch the video, so apologies if I missed his point somehow.

He went into detail of how eyes, rods m/cones, FPS/hz and motion blur all work....many interesting details.

Side note, I did find it funny, one time I showed a friend the insect demo on my X and he couldn’t tell the difference, when toggling on and off 4k, until I pointed them out :(
 
4k movies look amazing though. The improvements are definitely getting more and more incremental for sure though.

What I find funny about 4k is that you see clearly at all sorts of distances. In Blade Runner 2049 in 4k, every neon sign is crystal clear. In real life, our eyes would never be that good. I was in a 4th floor office talking 4k with some colleagues and we were joking about it. I looked down and at a distance everything is less defined and blurry. If you took a 4k monitor and showed the same view, it would look unrealistically good.

Get glasses. 😝

What you’re explaining isn’t about eyes not being able to see the details. If you have 20/20, you can see high detail at a great distance. Where camera are superior to eyes is the ability to close the iris of the lense to bring more distance objects in focus along with the close objects.

The smaller the opening in a lense the greater detail at different distances, i.e., asomething at 15ft will be just as sharp as something at 100ft at f22. Our eyes, at best, in extreme bright situations is about f8. Now, the same scene above at f1.4, focused on something 15ft away, 100ft in the distance will be nearly indiscernible because of of blurry the objects will be.

Normal, around the house eyes “fstop” is probably in the f4 range.

The notion the video is making that we don’t see in 4K is nonsense. We see well beyond 4k. Sure, the image degrades in our peripheral, but if your vision is good, what’s you’re focused on is beyond anything a camera can capture.
 
Aren't we all forgetting that...it depends? It's not "He's right" or "He's wrong". Viewing distance and screen size are pretty important factors here correct?

In the video he does make note that the human eye can see well above and beyond 4k, I’m too lazy to watch it, again, atm to get
 
Bottom line is 4K is better than 1080p. Cracks me up how many PC gamers on youtube say 4K isn't worth it, maybe because they are playing on a small screen(compared to most TV's) less than two feet away but if you are a gamer who plays on something 44 inch and above you'll be sitting several feet away and the higher resolution is pretty easy to notice.
