TV Explained: 4K, 8K, 16K and Why Beyond 4K is Useless

[Music] hey welcome guys this video explaining about 4k 8 K 16 K technology which is as soon as give me the next thing after 8 K we don't know that but there is 16 K I'll explain how that works and also I'll explain later on closes the end of the video why if you just bought an expensive 1080p TV a few years ago or a 4k TV recently and you just heard about a K don't kick yourself it's not that bad it's honestly a waste of money for a lot of people and I'm saying that as a tech youtuber I'm gonna explaining there's actual science behind it why I'm saying that so let's get into it right away but I'm gonna start with 720p and I know it sounds like it going backwards but 720p was a first standardized high definition TV standard for consumers so I want to understand 720p 1080p will take a few seconds to understand 4k 8 K 16 K takes mere seconds after that it's the same concept over the P in 720p or 1080p or 2160p which is 4 K stands for progressive not pixel anyone who does use pixel Donington they don't what they're talking about and explain the concept of progressive in a different video I'll put a link to in the video description but let's jump straight into it so we don't need to know much about progressive for this but that's what the P stands for so 720p which is a first standard HD has a resolution of 1280 by 720 so we'll take a TV doesn't matter what size we don't care this is our 720p TV what this basically means is that we have pixels now we care about pixels and pixels are tiny little dots on the TV thousands millions on there to pay on your TV that change colors as the motion changes on your TV so it looks like you have a moving object but they're actually still pixels just constantly changing colors to match the color so what happens is on the 720p TV you have 1280 little pixels going across horizontally and that happens 720 times so 1,280 online to 1280 pixels on line three so on and so forth and that happened 720 times that's where we get the number 720 720 p now it doesn't matter if the TV is 37 inches or 90 inches 720p is 720p well let's jump over to 1080 P like I promised is gonna be really fast 1080 is based on 1920 by 1080 and as you would've guessed it's the exact same concept you have 1920 little pixels going across and that happens 1080 times so imagine you have 1920 columns of pixels going across and then 1080 rows of that happen that's where you get 1080 for 1080p okay so 4k is where things are a little shady I guess you could say so 4k the initial standard is cinema 4k right and it has a resolution of 4096 by 2160 cinema 4k is designed for cinemas makes sense right however cinemas have a different aspect ratio than consumer TVs aspect ratio very quickly I'm not gonna get too many technical details it's basically the shape of the TVs so for example 4 by 3 TVs which are like standard definition before HD or well it's 4 by 3 is a very close number 4 and 3 are very similar so it'll look almost like a square widescreen TVs for example you have different filming formats it can be 16 by 10 16 by 9 bowls will you 16 by 9 16 by 9 is more widescreen right this is where this kind of changes at the cinema level the aspect ratio is different than it would be for a consumer TV at your home so they can keep the 2160 the same that's no problem we can't have 4096 520 less 60 on consumer TVs it doesn't make any sense so they're like well how do we make it match the aspect ratio of a widescreen TV we have to shrink it a little bit to 3840 this difference is so minuscule it's almost impossible to tell the human eye there's so many pixels here it's really difficult to tell this is also where the name 4k comes from for K stands for 4,000 90 pixels but obviously you should know that K stands for a thousand well it's four thousand pixels right across right now you're thinking hold on a second four thousand pixels at the sim 11 but there's not four thousand pixels at the consumer level am i getting ripped off it's how you want to look at it it's marketing gimmick um honestly II when you buy a computer monitor if you buy one that says 23 inches technically is twenty two point five yeah marketing garbage it's also easier to save 4k than it is to say 2160p and also think about it this way it's another marketing gimmick that 4k makes you think of 4,000 initially that's what your brain is thinking 4,000 sounds like a bigger number and then 2160 more marketing garbage so they're not reading lying there no one actually said hey 4k means you have 4,000 pixels across it's just a name it's just a naming convention and we based it on this so no one's actually lying but that's what it means I saw again for 4k TVs is 3840 by 2160 which is you get 2160p that's the standard for 4k some other concept for aka you have 7600 pixels or 7680 to be precise going across and that happens four thousand three hundred twenty times so it's 43 20 P that's what 8k would be considered again no notice it's not actually eight thousand seventy six but no one's gonna call it seven point six K so like that surround it up let's call a 8k just simpler that way more marketing garbage but that's what it is okay so as of this video recording date we don't know what's after 8k or at least what is gonna be the standard after eight K this is just an assumption because it seems to double you know 1080p 2160p you and so forth and up until you reach 86 40 P so I'm just assuming here but hey one day we might reach 16 K or it might just skip it altogether around but 16 K similar situation 1530 1015 thousand we're in the double digits of ten thousands 50,000 360 by eighty six forty seeing concept to you're seeing concept here again you notice it's not sixteen thousand pixels more marketing garbage so let's pretend to go to TV store to TV sizes identical forty seven inch that's 1080p 47 inch that's 4k chances are you will be able to tell the difference in quality and sharpness detail the reason being is because there's millions and millions of pixels packed in here millions and millions of millions of pixels packed in here the human eye just will barely be able to tell the difference the only reason the 4k will look better primarily is because it's the newer technology so TV manufacturers like Sony Samsung they're investing and making the colors look better here but the sharpness will look very identical I bought my parents a 1080p TV 50-inch I think four years ago it still looks better if not just the same as 4k TVs and a 50-inch now and they're more expensive ironically so it's not about oh there's not enough 4k TV channels ask my fork is useless know there's Netflix Amazon Prime is you to like this video you guys are watching in 4k 60 frames a second there's a lot of 4k content but the science is what's gonna help you argue that you don't need anything at 4k at a certain size for example but let's argue where 4k and 8k might be good let's pretend you get much bigger you have a 110 inch projector screen 1080p will look good on it I'm not gonna argue that it will look good but when you stretch out 1080p you have to understand 1080p at 47 inches or 110 inches it's the same amount of pixel count it doesn't matter how much you stretch it those pixels be spread apart more on 110 inch projector screen so they look slightly blurred compared to a 47 inch 1080p TV now a 4k a 110 inch projector will look much better because you're stretching all those additional millions of pixels across a wider area so that's where 4k will shine on like say one hundred and ten inch projector screen but again the amount of pixels going from 47 inch 210 inch it always stays the same resolution never changes on screen size very important thing to know well what does 8k shine it's a good question well when you're going to be on 100 inches it even then depends how close or far you're sitting from the screen distance sitting from a TV also matters on whether or not you can tell the difference between certain resolutions if you go to movie theaters that's where 8k and 16k will look amazing because this the screen size is so massive that's why a lot of gaming monitors for a good chunk of time if they were 4k would not be smaller than 28 inches it didn't make any sense same concept with TVs so hope you guys found this video so if you did it sure took my social links
