You Don’t See in 4K

The next big thing when it comes to home entertainment
is 4K TVs. And they’re stupid. Now if you didn’t figure this out from my
self-driving cars video, I’m just taking a holy grail of reddit and deconstructing
it in order to talk about vision – and maybe flirt a little bit with color finally. 4K TVs will happen eventually, but they’re
kind of wasted on most people. So let’s get started. Now, this video is currently being filmed
in 1080p at 30 frames a second – actually 29.97 frames per second but… 30, okay? And this is pretty much the current standard
format for most media, including Youtube. So let’s step back in time a bit and see
how we got here. This is 480i. But this is clearly too small so let’s uh… There we go. If you’re older than 20, you should recognize
this. This is what home television was for most
of its history. Now, there were lower resolutions, but we
have to start somewhere okay? The resolution is 640 by 480, which is where
the 480 in 480i comes from, the vertical resolution… this becomes important later. But let’s talk about the I, this stands
for interlaced. There is a difference between the field rate
and the frame rate. The field rate or refresh rate is 60 Hz, while
the actual frame rate is still 30. So you’re getting half a frame, interlaced,
each time. It may not be obvious with this video, but
you’ve likely seen something like this in lower quality videos… this is called combing
and now you know why. This is also why old CRT monitors and TVs
would flicker or have that rolling bar when you filmed them, because the camera frame
rate and the screen frame rate didn’t match up. And this is the format which VHS tapes were
in. Home video and VHS tapes weren’t really
a thing until Top Gun in 1987. That was the “must have” VHS tape and
the one that basically started the whole home theater industry… that’s just a funny
side note re- actually, you know why? VHS tapes used to cost upwards of a hundred
dollars, but Top Gun brought the price way down by having a Diet Pepsi ad in the beginning… You remember the ad. Anyway, VHS was a horrible format. It was just a magnetic tape. Not only did it degrade over time, but it
also degraded with each viewing. So the hundredth time you watched it, it would
be noticeably worse than the first time. So it needed to be replaced. This is 480p, the format of DVDs, you probably
didn’t notice much of a difference though. DVDs are to VHS tapes what CDs were to Audio
cassettes. The only difference is that the storage medium
was far more durable and resistant to degradation and the p. That stands for progressive, which unlike
interlaced, means you’re getting a full frame every single time without and combing. Now, a common saying among the non-techno
elite is that porn decides what the next video format will be. And that’s only been true once, during the
VHS and Betamax war of the 80s. But ever since then, it’s been video games. Most peoples’ first DVD player was the Playstation
2… and the must-have DVD was the Matrix, which came out in 1999. Every single person in high school right now
was born after the Matrix came out. Feel old yet? So the transition from VHS to DVD was fairly
quick because it was necessary and film studios finally stopped releasing VHS tapes in 2006. That really feels like it should have been
longer ago. Anyway, by 2006, people were starting to transition
to… High Definition (HD). You’ve probably noticed that we’re in
widescreen now. This ratio is known as 16 by 9, as opposed
to 4 by 3 which is known as fullscreen. Remember when old movies would say “This
film has been modified from its original version. It has been formatted to fit this screen?” What they’re saying is that they cut the
sides off to make it 4 by 3. So widescreen is the actual movie, not – as
I stupidly thought when I was a kid – the movie with black bars on the top and bottom. So HD not only made the resolution better
by making it 1280 by 720, which is one and a half times the size of 480, but also standardized
widescreen… which is far more accurate to what you actually see since you have two horizontally
placed eyes, making your horizontal viewing angle almost double your vertical. 720p is kind of forgotten middle child because
it came out at the same time as 1080i, and very shortly after, 1080
p… also known as Full High Definition There, that’s more like what you’re used to I
hope. It’s 1.5 times the size of 720p, so 2 and
a quarter the size of of 480p, at 1920 by 1080, and still 30 frames a second. Much like in the 80s, from 2006 to 2008 was
the Bluray vs. HD-DVD war, spearheaded by the video game consoles, the Playstation 3
and the Xbox 360. They were both the pretty much the same format,
1080p, with slightly different compression. So they were only competing to see who could
get the most sales, which Bluray won partially because the Playstation 3 came with a bluray
player built-in, unlike the 360’s HD-DVD which you had to buy… separately… that
was so dumb. There were no “must-haves” or memorable
“firsts” when it came to Bluray like with the previous formats, but the first bluray
movies came out in June 2006. 50 First Dates, for f… So here we are, in the current mainstream
format. Why did I just talk you through the history
and evolution of video formats? Because we’re already talking about upgrading
to the next formats, yet again spearheaded by the gaming consoles, the PS4 and Xbox One. Before we get into the resolution changes,
let’s talk about framerate. As I said, this video is being filmed and
shown to you in 30 frames per second or fps. But there’s been a recent shift to 60 frames
per second. Yeah, I know, we round up, I don’t know
why that is. Now, framerate is a sacred cow in the gaming
community and on reddit, and they will defend their framerate more angrily than the second
amendment people, so I have to tread lightly. Let me start this off by saying that the average
person watching my video, whether you’re a subscriber or you found this on reddit,
is not the average consumer. You’re probably an early-adopter… you
are the techno elite. Not the average consumer. Remember when you thought 3D TV, Google Glass,
and VR were going to be the next big thing? Pepperidge Farm remembers… Now… the human eye doesn’t see in frames
– you see pretty much continuously – But. Beyond a certain speed, things can move too
fast for you to notice. Now depending on the source, at that seems
to be about 45 to 72 frames per second. Let’s go with 72. That means, just sitting there on your couch
eating doritos, if something appears on screen for 1/72nd of a second, odds are you’ll
miss it. Unless you know where to look and you’re
waiting for it. That’s at rest though. Your perceived framerate changes based on
your arousal level. If you just went for a run, or are being chased
by a dinosaur, or more likely, you’re hopped up on caffeine, you can see up to about 120
frames per second. And if you’re a super human, like a fighter
pilot, or you’re on cocaine or something, you might be able to see up to 240, but nobody
has been able to do it reliably beyond that. If you still think you can, you belong in
a lab because you’re some sort of mutant. So again, you don’t really see in frames
per second, but if something appears and disappears above a certain frame rate, you probably won’t
notice. 30 frames a second was established as the
standard decades ago, and I’ll get to why in a moment. But 60 frames seems to be where economic use
of energy and human perception meet. PC Gaming has been at or above 60 frames a
second for decades, and most computer screens are 60 Hz, so they top out at 60 frames a
second. If you brag about your 150 fps on your 60
Hz screen well… I won’t ruin the illusion for you I guess. For a while after HD came out, they started
pushing different framerates. When we’re talking about screens, they call
them hertz, but hertz is framerate. First it was 60, then 120, and then 240…
and then they stopped because the average consumer was complaining. Why would that be if we don’t really see
in frames per second? Because of the Soap Opera Effect. The Soap Opera Effect is when things are too
crisp and too fluid for real life, giving it an eerie look and causing motion sickness. Move your hand in front of your face. There was a significant blur, wasn’t there? This isn’t set to film in 60fps so let me…
there we go. So the soap opera effect makes things look
like they’re moving in slow motion, but at regular speed. I know, it’s weird which is why it gives
people motion sickness. The Soap Opera Effect doesn’t affect video
games, because a) it’s not real life so nothing really looks strange, and b) they
program in motion blur. So they’ve kind of stopped with the 240
and are only pushing 120 and 60, 60 being the likely new standard. However, framerate isn’t uniform across
your entire field of vision, which I’ll get to in a moment. The next big format shift is to 4K or Ultra
HD, which is a stupid name by the way – it’s just something they came up with in a marketing
meeting to make it sound more epic. Remember the naming conventions from before? 480, 720, 1080, there’s a nice pattern going
there. But 4K is four times the size of 1080p, so
you would think it would be called 4X. But it’s only twice the width and height,
so if we go by the same naming convention, it’s 2160p. So where does 4K come from? The horizontal measurement, 3840, rounded
up… to 4k. If we go by that naming convention, regular
1080p is actually 2K. I told you it’s dumb. Anyway, HD was a huge jump from regular D.
Most people can easily tell the difference. But HD to 4K? Most people can’t. Again, you are not the average consumer. And remember, you’re usually sitting about
10 feet away from your TV, or at least you should be. Actually, the myth that if you sit too close
to the TV, you’ll damage your eyes, is kinda true, but not for the reasons you were told
as a kid. It has nothing to do with the flickering or
the pixels or anything. It has to do with the fact that you’re not
changing your depth perception or focal length any. While you’re watching TV or playing a game,
your brain is perceiving distance, but everything, whether it’s the guy in the background or
your own character, are the same distance away. So your eyes never really have to adjust and
they get strained and fatigued. You won’t really damage your eyes, but they
will hurt. This would happen whether you’re watching
TV or you go outside and stare at the same tree for three hours straight. Anyway, 4K is 3840 by 2160, which means there
are 8 million 294 thousand 400 pixels, or just 8.3 megapixels for short. For a 60 inch TV, that means an individual
pixel is a third of a millimeter wide. Put a dot on a piece of paper only a third
of a millimeter wide and then put it ten feet away. Okay you probably still see it because it’s
a black dot on a white piece of paper but… okay? You know what I’m getting at. But you know what? There’s been a single black pixel right
here for the least few seconds. Go back and watch it again, you probably didn’t
notice. And this is 1080p, do you really think you
would have seen it if it was a quarter the size? Now get this, there are 8.3 million pixels
on that TV…. And there are only 6 million cones in your
eye… Yeah. But that isn’t even the whole story because
each pixel is actually three pixels in one, red, green, and blue… I hope you know that those are the primary
colors of light. But we only think that because we’re human. If you were to ask an alien what the three
primary colors are, they might say “Three? Silly Human, there are fifteen!” Though that’s pretty unlikely because- wait,
this isn’t the color episode stop! Anyway, the cones in your eye are ONLY red,
green, OR blue. And while the ratio isn’t exactly a third,
if we matched them all up to make a pixel, that means there are only 2 million “pixels”
in your eye. Before you say anything, rods don’t matter,
if cones are the pixels of your eye, rods are the backlight – you can’t see with
only rods but… stop trying to sidetrack me! Anyway, cones aren’t evenly spread across
your retina. Cones are concentrated in an area called the
fovea, which is only a third of a millimeter wide in the center of your retina. So while you’re looking at this screen and
think you see this… you actually see this. Now you have to take into account the fact
that we’re squishing about 210 degrees of your visual field down to maybe 15. But I’m actually still being generous. Of your visual field, your focal area is only
about 1 degree wide. Hold out your hand and look at one fingernail
– the other fingernails aren’t in focus. So as you can – hey! My eyes are up here! Actually, sidenote, if you’re talking to
someone you have a crush on, watch their mouth while they’re talking, for some reason,
they’ll pick up on that and start to like you more. Just a little tip on how to get the ladies
from Knowing Better *The more you know* But since most of your cones are concentrated
in the fovea, that also means that as you get out to the periphery, there’s less color
perception. The fovea is also where you get the highest
framerate, by the way, as I mentioned earlier. It’s the most important part of your vision,
and it’s the only thing that’s really tested when we figure out if you have 20/20
vision. Another sidenote, there’s no such thing
as “perfect vision” What 20/20 means is that at 20 feet away, you can read what most
other people can read at 20 feet away. If you have 20/100 vision, that means while
you’re reading it from 20 feet away, the average person can see it from 100 feet away. You have bad vision. But it’s okay because we all kinda do. Because while we do have some of the best
general purpose vision in the animal kingdom, our eyes are really poorly designed. All of your cones and rods are on your retina
in the back of your eye, and all those cells need blood… guess where all the blood vessels
are… Yeah, in front of the retina. So at all times, you are looking through a
field of blood, which your brain usually filters out but looks something like this. But all of those blood vessels have to get
back out of your eye somehow… which they do through a hole in the retina. Which results in a blind spot. Close your left eye… actually, remind me
about this in a second. Anyway, close your left eye and focus your
right eye on the cross to the left. And move either your head or your phone closer
or further away – once you hit the sweet spot, the circle will disappear. It will be different distance depending on
what size monitor you’re on, but if you’re watching this on a computer, it’s about
3 feet. Your brain fills in that spot with whatever
is surrounding it. It’s kind of cool when you think about it. So not only do you not see this, you see this…
but you also have this going on. And of course, that’s not the end of the
story, because if you close one – oh yeah. Okay. What do you see when you close one eye? If you think it’s this, you’re wrong. When you close your… left eye, your brain
receives a “no input” signal, and turns off all information coming from that retina. So you don’t see half-black, you see this. Don’t believe me? Close your left eye. Now cover your left eye. Now open it. See? There’s a huge difference. Kinda cool that your brain just shuts off
incoming information like that. Anyway, so again, you’re seeing this. With the addition of this fun mess… which
can be bigger or smaller depending on how lucky or unlucky you are. So you really think you need a massive TV
with pixels literally the size of dust mites with all of this going on? Again, 4k will happen, mostly because they’re
just going to stop making HDTVs, but not anytime soon. There’s virtually no content for 4k right
now. Anything before last year will never be in
true 4k because it wasn’t filmed in 4k. The current generation of bluray disc, the
triple layer, holds 125 gigabytes of data. Do you know how big a 90 minute 4k video is?
477 gigabytes. So okay, it probably won’t be on physical
media anytime soon. So streaming, obviously. Yeah, well, unless you live in a big city
and not somewhere rural or like, Australia, you- better ge- used to that happening a lot. The major hurdle for 4k right now is the file
size, it’s just too large. And there are virtually no games in 4k right
now because of how much processing power that would take. As of May 2017, only 0.82% of steam players
are even able to play in 4k… and Steam players are the PC Gaming elite… so yeah. And in terms of TVs, in 2016 only 25% of all
new TVs sold were 4k. If I were a betting man – which I am – I
would say that 4k is going to take another 5 to 10 years to catch on for the mainstream. Much like cars, most people don’t buy a
new TV until their current one breaks. 8k on the other hand, will never happen…
it’s just too much for too little payoff. If we look at video formats like soap. 480p, or DVD, is regular old soap. It was fine for most people for a long time,
and many people still use it. 1080p is a big antimicrobial step up, it’s
obviously better and if people can get it, they will. 4k is like, super mega antibacterial, kills
99.99% of everything soap. And 8k is massive overkill, 99.9999 – like
who cares, okay. There’s an upper limit to what is necessary,
and 8k has 16 times the pixel density as HD… that’s too much. That’s fives times as many pixels as cones
in your eye. You’re never going to get a TV with pixels
the size of atoms, and at a certain point, it’s just not an economical use of energy,
storage, or bandwidth. If you don’t have better than 20/20 vision,
this is lost on you, and most people don’t see or care about the difference. And if you don’t believe me, they still
make DVDs, and still sell them by the millions. Last week I posted a poll on twitter – shameless
plug to follow me on there – asking people if they were to buy a movie today what format
would they prefer. Not what could they afford, not what setup
do they have, which would they prefer. And here were the results. Again, my average subscriber is not the average
consumer, so if anything, this poll is skewed in 4k’s favor. Think of all the people out there who don’t
use Reddit, Youtube, or Twitter. These are the people who still buy the Bluray/DVD
combo pack for the DVD. So now I hope you understand a little bit
more about not just TVs and video formats, but how your eyes work and how your brain
cleans up the information it gets by a lot. I was exaggerating a little bit with some
of those effects, but not by much. Seriously, start to notice some of the weird
things about your vision that your brain filters out, it’s kind of amazing. And the next time you go out shopping for
a new TV, hopefully now, you’ll know better. So what was your first memorable bluray? Do you plan on switching to 4k? Let me know down in the comments and don’t

100 thoughts on “You Don’t See in 4K

  1. What was your first memorable bluray? Do you plan on upgrading to 4k?
    Also… anyone know why the blood field you're constantly looking through is blue? The answer will be revealed in my color video!

    And for the worried… I was putting sunbutter in Wheatley's mouth. It's totally safe but… maybe a little annoying. 😀

  2. (Late) Interesting video, but technology has been on a steep incline, so the time estimates were a little off. Netflix actually makes it a requirement that shows/movies are shot with atleast 4k cameras, so most shows people watch with a 4k tv are true 4k. Isn't it crazy how quickly we have been advancing? You should make a video about that.

  3. 4K has definitely come a long way since this video. A great video as always. I'd love to see a follow up on what you think of 4K availability recently.

  4. Note to dumbass: People do not see in a resolution, there is no limit to the amount of light our eyes can read

  5. film can be scanned to be noticeably better and i think has the image quality of the analogue equivalent of 8k.

    4k is just sharper and has more information. its just 1080 improved.

  6. I was shopping for a new TV in the Philippines and ran across a Samsung QLED 98 inch 8K for P3,999,999 which translates to about $80,000 US.

  7. Whose watching in 2019? The 4k and 8k is geared towards bigger screens where pixels can be easily visible. Thats why you don't see a lot of small TV 📺 in 4k. As demand for big screen continues its only logical that framrate and resolution will be improved. Remember years back 65" would have been taught to be too much for average user. Now I can't even stand my 50" as image seem too small

  8. His facial expression in the thumbnail is the look of someone that you caught farting but doesn't want to admit it.

  9. Coming here in 2019 and this video SAVED ME. About 5 years ago, I started getting motion sickness from fps games- just all of a sudden. I thought my body had changed somehow and just gave up and stopped playing my favorite games. Now I know… that was the year I got a TV with motion-smoothing!!! I turned it off on my tv and I can play fps games again!! They don't make me sick anymore! Hallelujah!

  10. you don't see in 4k? more like you don't see that those words make no fucking sense. the shear amount of stupidity that "you don't see in 4k" is alone should be common knowledge. however, if you think that, i won't stop you. not about to stop protesting you though.

  11. Just installed the first 98'' Samsung 8k in the U.S. a few weeks ago. Yes you can see the difference. They actually use AI to upscale all content to 8k. Pretty incredible but when you do see actual 8k content, which there is some build in, it is incredible!

    Also installed another 85'' Samsung 8k this week. same amazingness.

    Personal owner of 2 4k tvs and hate when content is shown in 1080(streaming obv). You can see the difference and I do not have amazing eyeballs. Yes I am that guy that wont watch a show in 720 or less.

  12. This guy just bought a 1080p monitor, then standing at the bus stop waiting to come home somebody told him about the new model thats out called 4k. He is pissed

  13. I bought a 4k TV but then realised that my Xbox one outputs most of my games in 720p so even though I'm playing on a 4k TV I'm playing in 720p 🙁

  14. Did you know that there are more possible games of chess than there are atoms in the universe. Thus there are not enough atoms in the universe to create a database that shows all the best moves of a chess game from the starting position. Also, you don't need high def to play chess.

  15. I bet the reason Youtube keeps recommending me this video is because of them trying to hide from the general public about their horrible bitrate.

  16. The reason why "hardcore" gamers want a high frame-rate (above 60fps) is a misconception. It's not that they can see more (or that they think they do), but that the games themselves are running their logic based off of that frame-rate… important stuff like controller input: the higher the frame-rate your game runs, the more frequently it'll look for your input and, thus, the better it'll feel.

    It's one of the primary reasons why most haven't adopted wireless devices and continue to use wired mice, keyboards, controllers, headphones, etc… compared to the general public despite typically being "ahead" in technology.

    P.S. – the difference between 30fps and 60fps is pretty noticeable… even if you're not giving any input. If it's a video, it might not look any different depending on how it was filmed and compressed.

  17. I've got both 4K and lower res screens; and I don't use the lower res screens anymore because they suck compared to 4k. Huge difference. Your arguments are flawed.

  18. He has a point but he makes a mistake he actually explains in the vid. Your eyes (and brain) focus on a small area on the (4K) screen meaning that you are not looking at 4k pixels but way less. Your eyes have more cones (etc) than pixels in the area you are focusing on. Meaning you will see a difference between 1080p and 4K (for example) in that small area at the same screen size. It will be the same at 8K (allready for sale). There is a point the cones (and things) in the eye will be less than the pixels you are watching in your focused area. What the number is I don't know but it will be in dpi. The higher the resolution the higher the dpi at the same screen size. 4K and 8K are not so much about a clearer and sharper picture but more about making it possible to go to bigger (70" or more) screens and still having the sharpness (dpi) of a normal size 1080 screen which everybody loves. 4K and 8K will be useless on your smartphone but will be necessary on you fullwall-tv.

  19. "About 25% of new tv sales in 2016 were 4k"

    20% of your twitter poll supported 4k. If we assume your poll was for the average consumer, then a majority of people who have 4k would prefer content in 4k rather than lower resolutions

  20. 1st thanks for the informative content and 2nd yes I'm planning on switching to 4k simply because at age 35 I still want to feel like I'm keeping up with the latest of modern home technology!

  21. I agree with the main theme of the article that there is little discernable difference between 1080 and 4K from the viewers perspective, there are a few inaccuracies. The first is that there are only 2 million cones in the eye and therefore we can't detect resolutions higher than that. Yes, there are about 2 million cones of each colour type in an eye, but we have two eyes. An image also isn't just made up of colours; there's texture and contrast as well. All six million cones of each eye play a role in detecting this. It is also problematic to compare TV screens with true vision in terms of resolution. TV's display a sequence of still images. The resolution of each image is therefore very easy to calculate. The human eye produces a live stream of data. The brain then takes this data and forms a model of what's going on, overlaying the data of the same object again and again. Our eyes move imperceptibly from side to side to provide even greater resolution. The final image that we 'see' is not simply the light reaching our eyes at a given moment in time. The bottom line is that we can easily see a difference between 1080p and 4K from a purely technical aspect given nornal vision. But, for those of us who have watched numerous 4k shows, the question is, do you really notice when engrossed in the film? I have to say that I don't. I do see a difference with side-by-side comparisons. But when just simply watching a film, I certainly couldn't tell you which films I'd seen in 4K. But a lot of this will have to do with the amount of action (at 60fps, a moving object blurs whether it is HD or 4K) and how good the actual source material is. I remember back when HD was the next big thing I saw The Rockford Files in HD. Of course, the source footage was from the 70s and wasn't HD… but it was being broadcast in HD. So technically, they could claim it was HD!

    Just one other small point of pedantism – 4K and UHD (U-HD) were not, technically, the same thing. 4K had 4096 lines of vertical resolution, UHD had 3840. Although, I've seen a whole bunch of manufacturers selling 3840 line TVs as 4K, so perhaps the lines are now blurred.

  22. What do you think about 4K now 2019-08-07 @ 23:39:16 considering that it is pretty much the current default format in TV, PC monitors and even in smartphones shooting 4K? And the 8K which is never ever going to happen? Ha. We are at the threshold of that happening right now and already there are 8K TV panels on the market. Oh, and as an aside, 16K is in R&D. Enjoy! 🙂

  23. While human eyes are not rated in pixels an approximation of what we can see is 40 megapixels where 8K is 33 megapixels. But our eyes don't see everything in equal resolution. … Anything above 8K is effectively better than our eyes can see.

  24. For me, 1080p still looks good enough for most things. 4k does look better to me though. 8k though? I can't tell it apart from 4k other than the price. Bear in mind that I'm talking about TVs and not monitors.

  25. In all fairness, freezing the drinks is a good idea…as long as you remember to get it 15 minutes later.

  26. Worth noting that the reasons for a higher framerate for gaming are slightly different different. For TV, the higher the framerate the closer it is to continuous. For gaming there's that, but it also reduces input lag. If you're at 30fps, there's going to be a 1/30 of a second difference between your input and the game registering it. This matters for certain games more than others. For fighting games or high octane shooters, 60fps really does make a difference. For turn based strategy, framerate is basically irrelevant.

  27. It is true that we have less cones in our retina than pixels in 4K, and it is also true that outside the fovea we have less visual resolution, but it is that very fovea that makes 4K worth it. IF you are sitting close enough to a large enough screen then it gives you the freedom to aim your fovea at any part of the screen that might have detail and see the crisp detail in all its glory. You won't see all the detail all the time but you can see any of the detail any of the time. You can also pause 4K video and examine it like a picture up close or take a screenshot to use for the background on the 4K TV you are using as a computer monitor. With 4K, we are finally reaching the resolution that print has had forever. I find that stuff filmed in 4K looks better quality than stuff filmed 1080p, even if I am watching it scaled down to 1080p. For example, check out the 1.5 hour video of 4K footage from the ISS. But I agree that 8K is overkill for general purposes; it can have special applications though.

  28. Hey I’m Australian and NEVER get any stop starts in videos or games, like, EVER. But Brisbane does have the best down here.

  29. I'm so tired of the "you don't see in whatever". It's BS! They said the same thing about framerates over 30. You can tell the difference, especially on large monitors. It's all about pixel density.

  30. Also, in FPS, there are differences in perceived fluidity weather or not you can see the actual frames or differences.

  31. It's not about what your eyes can see, it's about how big you can make the monitor/screen. If it's 4K, you can have a computer monitor be as big as your biggest screen TV and still have it look super-crisp.

  32. the only thing i disagree with, with this video, is the general mass buys 4k tvs and the people who are big on tech avoid it cuz they know you don't see in 4k, the same sort of people who buy a smart tv but already own a streaming device, are the people who buy 4k it's the people who don't know any better, they're the same people who buy those stupid curve tvs.

  33. As far as steam, since most game play is on a smaller screen, many laptops in here, for the most part 4k is not desired this why such a small % play in 4k. On a TV with large screens its different.

  34. I never knew why I didn't like some of the HDTVs I'd watched in stores or at friend's houses, because the picture looked…"too real" and I had a hard time watching. The Soap Opera Effect, as you called it, nailed it perfectly. And I'm glad I didn't just on the Blu-ray bandwagon, since for me the quality really wasn't different.

  35. This didn't hold up very well. In fact, I think his predictions were wrong in 2017 when this came out.

    The whole idea that there are more pixels than cones in your eye doesn't matter at all. You can always improve. At least until there are more pixels in each square inch of a huge theater screen than there are cones in your eyes. You want to be able to focus on a tiny portion of the screen and still get perfect clarity. I don't get it because he mentions this fact in the video but ignores it later on.

  36. I think you don't understand the objective of 4k TV. The objective isn't to see the difference betwen 1080p and 4k, but to make the edges of things like constructions, hair, wires and other things more defined, of course if you take a 1080p tv with a flat image like just some colors without diagonal edges and the same image at 4k on a 4k tv, you'll not see any diference, even if both of them have a black pixel as you pointed out. But when you start to play games or watch even movies and start to see diagonal edges you will
    definitively preffer a 4k tv, even if your eye can't really see the difference betwen individual pixels. To undestand what I'm talking about, just research about AA on games, is the same thing as simulating a higher resolution to correct the "stairs" effect at the diagonal edges, even in 1080p, if you play without it, it will look shit.

  37. From someone with 15/20 vision (not bragging) my Samsung q80r looks better than real life and I know that doesn’t make any damn since but it does, the color is more vibrant and detail/definition is insane. I can watch something in 4K wether it be Netflix (stranger things) or a 4K movie on anything else I can tell an enormous difference from 1080p, 1080p is like ok I can see this clearly and clean then 4K is just wow. As far as frame rates go 60 to 120 to 144 I can tell a difference as for 240 I had a Sony tv with a 240hz refresh rate and as it did look fake at times you quickly get used to it and when your watching extremely fast scenes like a mission impossible movie it looks really good. And as for marketing don’t blame the corporate guys blame the people with lower IQ that go wow 4K that sounds impressive when they have no idea what it means.

  38. I have a 65 inch 4K HDR Tv with an Xbox one X.
    If you are gonna upgrade your films from blu Ray to 4K, I’ll let you in on a little secret, any film shot digitally in the last 5 years will look good, a little better but not drastically better. Now, Any movie shot on film from the last 20 years will see a MASSIVE upgrade from blu Ray and is well worth the investment and you will notice a massive difference.
