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
