it seems like we were only just getting used to HDMI 2.0 as the new normal with
0:06
its support for 4k resolution at 60
0:09
hertz making it a viable option for gamers and enthusiasts but there's
0:13
already something much more impressive on the horizon the recently announced
0:18
HDMI 2.1
0:21
of course going from 2.0 to 2.1 might
0:25
not sound like a huge leap for mankind
0:28
think about how unexciting the transition from Windows 8 to 8.1 was
0:34
but this new revision of HDMI actually has
0:37
massively enhanced uh capabilities
0:42
first up let's talk resolution 4k 5k and
0:46
even 8k are child's play for the new HDMI 2.1
0:51
which supports content at up to 10
0:54
k and although the HDMI forum hasn't yet
0:58
said if 10k means the typical
1:01
16x9 aspect ratio with about 10 000
1:04
pixels across or something more widescreen and cinematic
1:09
it definitely far outstrips the 4k
1:12
resolution of older hdmis
1:16
perhaps even more impressively though HDMI 2.1 can handle these absurd
1:21
resolutions at equally absurd frame
1:24
rates we're talking 120 hertz at 10
1:29
k which makes even the ak 60 hertz
1:33
capabilities of the latest displayport revision 1.4 look positively pedestrian
1:40
and although you would need a seriously incredible video card in your computer
1:45
to push that many pixels in a game you can still perhaps look forward to ultra
1:51
smooth movies and videos on youtube at
1:55
staggering resolutions and on the subject of gaming HDMI 2.1
2:00
will support its own variable refresh rate technology simply called
2:05
game mode vrr this allows a source device like a pc or
2:10
a game console and a connected display to synchronize their refresh rates and
2:16
thus avoid pesky screen tearing similar
2:19
to NVIDIA's g-sync and AMD's freesync which you can learn more about here
2:24
hopefully this will finally make adaptive refresh much more accessible
2:29
than the fragmented bundle of ecosystems
2:32
that we have now and that's not all it can do to make
2:36
your content look more real than ever before
2:39
like HDMI 2.0 2.1 supports HDR or high
2:44
dynamic range which expands black and white levels as well as color ranges
2:50
especially in bright and dark scenes you can learn more about HDR here but HDMI
2:56
2.1 takes the concept a step further
2:59
with dynamic metadata this allows the exact range of luminance
3:05
to be varied on a per-frame basis and
3:09
although the existing dolby vision HDR standard also supports dynamic metadata
3:15
it's a proprietary standard whereas the hdr10 standard is open meaning more
3:22
devices at lower prices
3:25
and of course HDMI carries audio along
3:28
with your video so there are improvements for your ears as well we'll
3:32
be getting a feature called enhanced audio return channel enabling
3:38
object-based audio schemes like dolby
3:41
atmos and dts x meaning each sound in the movie or show
3:46
that you're watching is encoded as its own specific object
3:51
instead of just having a limited number of discrete channels making positional
3:56
audio more realistic whether you have four speakers in your setup or 24
4:02
but all of this new stuff means HDMI 2.1 needs a larger pipe with
4:09
higher bandwidth 48 gigabits per second
4:14
to be exact which is over twice as much
4:17
as HDMI 2.0 and even faster than current
4:22
m.2 pci express ssds
4:26
there is bad news though in addition to buying a new tv a new
4:31
source device and new copies of all of your content you will even need new HDMI
4:37
2.1 cables to take advantage of the
4:41
higher resolutions just make sure that you don't get
4:44
hoodwinked into buying one of those thousand dollar silver ones from wire
4:48
world racing against the clock as a freelancer
4:52
challenging yes but with the growth of the internet
4:56
there's never been more opportunities for the self-employed and come on did
5:02
you have a degree in accounting already
5:05
i didn't think so but freshbooks
5:08

5:12
designed to make your life simpler and
5:15
save you time not to mention help you get more organized you can create and

5:24

5:28
when your client has seen the invoice and put an end to the guessing games you
5:32
