TV Explained: 4K, 8K, 16K and Why Beyond 4K is Useless
Today I will be explaining about 4k, 8 K, 16 K technology. I’ll explain how these technologies work, and also I’ll explain later on closes the end of the post 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 many people, and I’m saying that as a tech person. I’m going to explaining there’s actual science behind it. I’m going to start with 720p, and I know it sounds like it going backward, but 720p was a first standardized high definition TV standard for consumers, so I want to understand 720p and 1080p will take a few seconds to understand and 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. So we don’t need to know much about progressive for this, but that’s what the P stands for, so 720p, 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 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.
It looks like you have a moving object, but they’re still pixels, just constantly changing colors to match the color. Hence, 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. now it doesn’t matter if the TV is 37 inches or 90 inches 720p is 720p.
Let’s jump over to 1080 P as I promised it is going to be fast 1080 is based on 1920 by 1080, and as you would’ve guessed, it’s the same concept you have 1920 little pixels going across that happens 1080 times. Imagine you have 1920 columns of pixels going across, and then 1080 rows of that happen. That’s where you get 1080 for 1080p.
4k TV 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; however, cinemas have a different aspect ratio than the consumer TV aspect ratio. I’m not going to get too many technical details; it’s the shape of the TVs. So, for example, four by 3 TVs, which are like standard definition before HD or well, it’s four by 3, very close numbers 4, and 3 are very similar, so it’ll look almost like a square widescreen TV. For example, you have different filming formats. It can be 16 by 10 or 16 by 9. 16 by nine is more widescreen, and this is where this kind of change at the cinema level.
The aspect ratio is different than it would be for a consumer TV at your home to keep 2160 the same that’s no problem. We can’t have 4096, which is 520 less 60 on consumer TVs. It doesn’t make any sense, so they’re like well how we make it match the aspect ratio of a widescreen TV; we have to shrink it a little bit to 3840, and this difference is so minuscule. It’s almost impossible to tell the human eye there are so many pixels here. It’s tough to tell this is also where the name 4k comes from for K stands for 4,090 pixels, but 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 consumer level, but there are not four thousand pixels at the consumer level. When you buy a computer monitor, if you buy one that says 23 inches technically is 22.5 inches. It’s also easier to say 4k than it is to say 2160p and thinks 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 more significant number. There no one 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 lying but that’s what it means. I saw it 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 4320 P. That’s what 8k would be considered. It’s not eight thousand seventy-six, but no one’s going to call it seven point six K so like that surround it up, let’s call an 8k just more straightforward. So as of this Post date, we don’t know what’s after 8k or at least what is going to be the standard after 8K.
4K, 8K, 16K and Why Beyond 4K is Useless
So I’m just assuming here, but hey one day we might reach 16 Kor skip it altogether around but 16 K similar situation. Let’s pretend to go to the TV store to TV sizes identical forty-seven inches, which’s 1080p and 47 inches 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 will barely be able to tell the difference the only reason the 4k will look better primarily is that 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 to 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. Still, the science is going to help you argue that you don’t need anything at 4k at a specific size. Let’s argue where 4k and 8k might be right. Let’s pretend you get much bigger you have a 110-inch projector screen 1080p will look good on it I’m not going to argue that it will look good. Still, 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 the 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 full 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 inches to 110 inches it always stays the same resolution never changes on screen size. 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 specific 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 not be smaller than 28 inches. it didn’t make any sense the same concept with TVs
