00:00:00.199 --> 00:00:07.439
have you been in the market for a new TV lately if so you've probably noticed

00:00:05.200 --> 00:00:12.679
that the TV manufacturers and big box stores use a number of tricks to lure

00:00:10.519 --> 00:00:19.119
you in they mostly Focus their advertising on the same stuff High

00:00:15.160 --> 00:00:20.720
resolutions huge screen sizes and rock

00:00:19.119 --> 00:00:26.640
bottom prices all designed to convince you to

00:00:23.760 --> 00:00:32.040
punch and elbow your way past a bunch of strangers on Black Friday like some sort

00:00:28.960 --> 00:00:35.559
of electronics piranha but there's a

00:00:32.040 --> 00:00:38.960
crucial often ignored element one that

00:00:35.559 --> 00:00:43.200
is arguably the biggest determinant of

00:00:38.960 --> 00:00:46.600
overall picture quality contrast

00:00:43.200 --> 00:00:48.000
ratio but what the heck is that well

00:00:46.600 --> 00:00:51.920
although it's not something that's always easy to find if you're buying a

00:00:50.000 --> 00:00:57.680
TV or a monitor Off the Shelf at a brick and mortar store you should have

00:00:54.719 --> 00:01:04.720
encountered contrast ratio at some point on a spec page if you're shopping online

00:01:00.079 --> 00:01:08.880
but what do those values 1,000 to 1 1

00:01:04.720 --> 00:01:11.080
million to one even mean well you see

00:01:08.880 --> 00:01:15.680
contrast ratio is essentially the difference between the brightest white

00:01:13.680 --> 00:01:21.640
that a screen can produce and the darkest black which is very important

00:01:18.880 --> 00:01:27.159
because having the correct brightness on different areas on screen is critical

00:01:24.600 --> 00:01:33.240
for making dark areas look sufficiently dark without losing detail and for

00:01:30.600 --> 00:01:39.799
optimal visibility in bright areas think of a shot of a city at night a TV with

00:01:36.439 --> 00:01:42.600
good contrast will clearly show you a

00:01:39.799 --> 00:01:48.640
dark night sky while making the detail of the city lights stand out if your

00:01:45.560 --> 00:01:50.840
screen contrast ratio is too low the

00:01:48.640 --> 00:01:55.840
entire scene will be less detailed and more washed out with dull stars on a

00:01:54.439 --> 00:02:02.680
charcoal backdrop typically modern IPS displays

00:01:59.640 --> 00:02:04.320
as as well as better-made TN panels will

00:02:02.680 --> 00:02:09.879
offer contrast ratios in the neighborhood of a th000 to1 meaning the

00:02:07.280 --> 00:02:16.200
brightest pixel will be a thousand times brighter than the dimmest if you opt for

00:02:13.000 --> 00:02:18.519
a more unusual VA type display you'll

00:02:16.200 --> 00:02:24.840
generally see better performance at least by this particular metric with

00:02:20.800 --> 00:02:27.879
contrast ratios between 2 and 5,000 to

00:02:24.840 --> 00:02:30.680
one but what about those spec sheets you

00:02:27.879 --> 00:02:37.879
see that advertise insane contrast ratios of like 10 million to one well if

00:02:34.680 --> 00:02:41.159
you look closely you'll see that these

00:02:37.879 --> 00:02:43.239
numbers indicate a dynamic contrast

00:02:41.159 --> 00:02:49.319
ratio which is a number that a manufacturer claims a display can

00:02:45.920 --> 00:02:52.200
achieve with backlight trickery so on

00:02:49.319 --> 00:02:57.599
lower end sets the entire backlight will be turned up or down depending on the

00:02:55.239 --> 00:03:02.319
brightness of the scene while on high-end ones this is done more GR

00:02:59.840 --> 00:03:09.040
granularly with certain parts of the scene being boosted or dimmed these

00:03:06.159 --> 00:03:15.200
dimming techniques are quite useful and can result in better picture quality but

00:03:12.680 --> 00:03:20.840
the experience definitely isn't the same as having a panel that can achieve

00:03:17.440 --> 00:03:23.440
natively an absurdly high contrast ratio

00:03:20.840 --> 00:03:28.640
like an OLED one whose pixels individually emit their own light

00:03:26.239 --> 00:03:35.959
without any backlight allowing them to perform this dimming functionality on a

00:03:31.519 --> 00:03:39.000
per pixel level they can even be turned

00:03:35.959 --> 00:03:41.200
off so long story short then unless

00:03:39.000 --> 00:03:47.280
we're talking about OLED you should take those 10 million to one numbers with a

00:03:43.840 --> 00:03:50.400
huge grain of salt and for that matter

00:03:47.280 --> 00:03:52.799
even oleds that might really have 10

00:03:50.400 --> 00:03:58.439
million to one contrast ratios are sometimes advertised as having infinite

00:03:55.159 --> 00:04:00.280
contrast that should really be undefined

00:03:58.439 --> 00:04:06.560
if you don't like divide by zero errors you guys speaking of divide by zero and

00:04:04.200 --> 00:04:10.879
math errors do you find accounting complicated do you wish as a small
