Poll of the Day > I can't tell the difference between 4k and 1080p video on a 4k monitor.

(+) Yeah! (+)

Is there even a difference?

---

Well 4K is 4X the resolution of 1080p

---

I can't tell the difference between 4K (2160) and HD (1440) period. There's a big difference between normal HD 1080 and 1440 but not much beyond that.

---

If the monitor isn't big enough and/or you're sitting too far away, you really aren't going to notice a difference.

its actually 2x not 4x.
1080 x 2 = 2160

1080 x 2 = 2160

right but it's a rectangle. so it's like tiling 1080p 4 times

Indeed. Doubling two dimensions increases the final product by 4.

I haven't actually compared before, but look at the smaller detail stuff. at a macro-scale it should look similar, but at a micro-scale (fine detail) the 1080 should get blurry before you can see much smaller-scale detail, whereas with the 4k you should be able to see a surprising amount of detail.

additionally due to certain video compression protocols (or something), many 1080 videos will actually already be less quality than they could be. I don't know the technical terms for it, but in many 1080 files the "shading" that is used per each "cell" of each frame is merged between clusters of four (each cluster has the same shade as the top left cell of the cluster, rather than each cell having its own shade). this often means that a 4k video will already look better than a 1080, even on a 1080 display, because the 4k will not have that issue.

Then you need glasses or the video isn't native 4K.

I was just looking at Youtube 1080p vs 4k. They looked virtually identical.
It was just some random Michael MJD video.

not very many people can tell the difference between 30fps and 60fps, let alone the difference between full hd, and 4k.

lol helly post

im not him, and biologically speaking human eyes do not have the capacity to actually tell the difference because evolutionary speaking it was never necessary.

our eyes are designed for contrast, not motion

30fps and 60fps is very obvious.

However, I am not one of those people who thinks that there is a huge difference between 60fps and 120fps. To me, 60 is fine, I would rather have higher resolutions than more fps.

At least you can stop claiming you never said you are not yourself.

Yeah I can absolutely tell the difference between 30 and 60. And as strange as it sounds, it's actually true. 30 to 60 is a bigger jump than 60 to 120. I can't really tell the difference between 60 and 120 either.

I have never seen 120fps, but theoretically where it should be noticeable is when turning quickly in first person, or similarly an object quickly travelling perpendicular to the camera (so left to right on the screen (or right to left)). in a lower frame rate, the number of actual frames you see as it passes will be a lot lower, maybe even just 1 or 2 depending on the speed, and they may have no overlap. in a higher fps, there should be many more frames. (I suppose twice as many in 120fps.)

(as fps approaches infinity, an object could move past you from left to right in front of you very quickly, and there would still be a frame for every position of the object, regardless of its speed (as IRL). with lower fps, the object might not even appear if it moved by fast enough since one second it was off-screen to the left, and the next it was off-screen to the right.)

It is. Shooters are amazing at 144fps.
