00:00:00.280 --> 00:00:06.080
so with our technology rapidly improving and our graphics cards and digital

00:00:04.279 --> 00:00:09.840
cameras pumping out crisper more lifelike images than ever before it

00:00:08.000 --> 00:00:14.320
isn't surprising that we're wondering how long it will be until we get

00:00:11.880 --> 00:00:20.600
something that could match or exceed our eyes natural resolution or refresh rate

00:00:17.600 --> 00:00:22.920
but what exactly are the specks of our

00:00:20.600 --> 00:00:27.760
eyes does the question even make sense since we see things not with a camera

00:00:24.720 --> 00:00:30.439
lens and GPU but with a squishy eyeball

00:00:27.760 --> 00:00:33.719
and a hunk of meat inside our brain now we here at Techquickie are not the

00:00:32.079 --> 00:00:38.879
first to answer this question in terms of discrete numbers but even so tons of

00:00:36.920 --> 00:00:43.600
people out there are still perpetuating the same myths like the famous assertion

00:00:41.760 --> 00:00:49.079
that the human eye can't see more than 24 frames per second which Garners eye

00:00:46.600 --> 00:00:53.879
rolls from enthusiasts everywhere so we're going to take a stab at explaining

00:00:50.960 --> 00:00:58.640
the truth obviously our eyes don't work exactly the same way as digital cameras

00:00:56.520 --> 00:01:03.239
but they do operate with a few Concepts in common just like an image sensor in a

00:01:01.280 --> 00:01:09.320
camera can capture a certain number of pixels our eyes have a finite number of

00:01:05.840 --> 00:01:11.439
Rod and Cone cells in them plus our eyes

00:01:09.320 --> 00:01:15.600
need different visual elements of whatever we're looking at to be small

00:01:13.560 --> 00:01:21.320
enough so that they don't appear pixelated so in this way our eyes are

00:01:18.320 --> 00:01:23.560
sort of kind of digital but our brains

00:01:21.320 --> 00:01:28.840
render images we can understand by examining how the view from our eyes is

00:01:26.240 --> 00:01:33.079
continuously changing which sounds a lot closer to how and analog technology

00:01:30.920 --> 00:01:39.360
Works something you can learn more about up here so this means that the commonly

00:01:35.920 --> 00:01:40.640
cited answer of 576 megapixels which was

00:01:39.360 --> 00:01:46.320
decided upon with some rather complicated math which we've linked to in the video description needs to be

00:01:44.119 --> 00:01:50.920
taken with some caveats don't get me wrong our eyes are indeed incredible

00:01:48.640 --> 00:01:58.320
tools for seeing the world in detail I mean 576 megapixels is equal to having a

00:01:54.799 --> 00:02:01.159
32,000 by 18,000 pixel monitor this

00:01:58.320 --> 00:02:08.720
would be like having an array of over 275 1080p monitors this makes it sound

00:02:05.640 --> 00:02:11.319
like you'd need 576 million pixels to

00:02:08.720 --> 00:02:15.200
have a photo that fit exactly within your field of view to completely fool

00:02:13.599 --> 00:02:19.720
you into thinking that the picture is actually real life but remember that

00:02:17.840 --> 00:02:23.560
since you only see things sharply that are right in front of you with your

00:02:21.400 --> 00:02:28.640
peripheral vision being a lot blurrier the actual number is only somewhere

00:02:25.480 --> 00:02:31.080
around 8 or 9 megapixels and again since

00:02:28.640 --> 00:02:35.400
your brains don't work in a digital manner the real number can vary quite a

00:02:33.360 --> 00:02:39.239
bit depending on factors like ambient lighting but let's say you're less

00:02:37.440 --> 00:02:43.280
worried about buying a camera that can match the capabilities of the human eye

00:02:41.360 --> 00:02:47.840
and more about buying a graphics card and high refresh rate monitor that can

00:02:45.480 --> 00:02:53.560
crank out so many FPS that your favorite game couldn't possibly appear any

00:02:50.120 --> 00:02:56.480
smoother is that even possible well

00:02:53.560 --> 00:03:00.680
possibly in theory a human brain could process a th000 frames per second

00:02:59.000 --> 00:03:06.000
according to scientific Research into how quickly our neurons can fire signals

00:03:03.720 --> 00:03:10.319
but just like the theoretical Max speeds of things like SATA drives this number

00:03:08.280 --> 00:03:15.360
doesn't mean a whole lot in Practical terms different people have different

00:03:12.879 --> 00:03:21.519
maximum refresh rates and the real life upper limit seems to be around 250 Hertz

00:03:19.239 --> 00:03:26.239
depending on what study you look at but remember again that our brains and eyes

00:03:23.280 --> 00:03:31.120
aren't exactly digital and don't render discret frames the way a graphics card

00:03:28.680 --> 00:03:36.799
would so there is an actual number of frames your eyes can push to your brain

00:03:33.640 --> 00:03:39.040
rather that 250 number is the point at

00:03:36.799 --> 00:03:43.439
which motion becomes realistic looking for people with good eyesight and of

00:03:41.360 --> 00:03:47.239
course there are diminishing returns as you approach this number for example

00:03:45.560 --> 00:03:54.799
it's easy for most people to tell the difference between 20 and 60 FPS but 220

00:03:51.519 --> 00:03:58.280
and 260 will be indistinguishable to a

00:03:54.799 --> 00:04:00.519
lot of folks so while it is possible to

00:03:58.280 --> 00:04:04.920
attach meaningful numbers to the spec sheets of our eyes and brains individual

00:04:02.959 --> 00:04:09.159
differences along with the not quite analog or digital nature of our bodies

00:04:07.640 --> 00:04:13.360
means that you should take them with a grain of salt and that the most

00:04:11.319 --> 00:04:17.680
important thing is to buy stuff that will give you an experience that you

00:04:15.400 --> 00:04:23.520
think looks good unless of course you're cool with waiting around for the world's

00:04:19.440 --> 00:04:26.440
first 18,000 P monitor to hit the market

00:04:23.520 --> 00:04:29.479
whoa I'm on Techquickie anyways tunnel bear VPN you can tunnel up to 20

00:04:28.240 --> 00:04:34.199
different countries and browse the internet internet as if you are in that

00:04:32.000 --> 00:04:38.479
country they have easy to use apps for iOS Android PC and mac and they also

00:04:36.440 --> 00:04:42.360
have a Chrome extension just choose the country that you want in the app turn

00:04:40.440 --> 00:04:46.280
tunnel bear on and watch as your bear tunnels your internet connection to a

00:04:43.720 --> 00:04:50.919
new location similar to how I just came here from LTT when you turn tunnel bear

00:04:49.199 --> 00:04:55.880
on two things happen your connection gets encrypted with AES 256bit

00:04:53.120 --> 00:04:59.360
encryption and your public IP address gets switched so you show up to other

00:04:57.880 --> 00:05:04.039
people as if you're in that country that you picked earlier they also have a

00:05:01.320 --> 00:05:08.479
toprated privacy policy and do not log user activity you can try tunnel bear

00:05:06.000 --> 00:05:12.600
VPN with 500 megabits of free data and with no credit card required and if you

00:05:10.560 --> 00:05:16.840
decide to get the unlimited data plan you can save 10% by going to Tunnel

00:05:14.280 --> 00:05:20.720

00:05:18.680 --> 00:05:25.080
dislike get subscribed if you haven't already and check out our other channel

00:05:23.039 --> 00:05:29.360
