it seems like we were only just getting used to HDMI 2.0 as the new normal with
its support for 4k resolution at 60
hertz making it a viable option for gamers and enthusiasts but there's
already something much more impressive on the horizon the recently announced
HDMI 2.1
of course going from 2.0 to 2.1 might
not sound like a huge leap for mankind
think about how unexciting the transition from Windows 8 to 8.1 was
but this new revision of HDMI actually has
massively enhanced uh capabilities
first up let's talk resolution 4k 5k and
even 8k are child's play for the new HDMI 2.1
which supports content at up to 10
k and although the HDMI forum hasn't yet
said if 10k means the typical
16x9 aspect ratio with about 10 000
pixels across or something more widescreen and cinematic
it definitely far outstrips the 4k
resolution of older hdmis
perhaps even more impressively though HDMI 2.1 can handle these absurd
resolutions at equally absurd frame
rates we're talking 120 hertz at 10
k which makes even the ak 60 hertz
capabilities of the latest displayport revision 1.4 look positively pedestrian
and although you would need a seriously incredible video card in your computer
to push that many pixels in a game you can still perhaps look forward to ultra
smooth movies and videos on youtube at
staggering resolutions and on the subject of gaming HDMI 2.1
will support its own variable refresh rate technology simply called
game mode vrr this allows a source device like a pc or
a game console and a connected display to synchronize their refresh rates and
thus avoid pesky screen tearing similar
to NVIDIA's g-sync and AMD's freesync which you can learn more about here
hopefully this will finally make adaptive refresh much more accessible
than the fragmented bundle of ecosystems
that we have now and that's not all it can do to make
your content look more real than ever before
like HDMI 2.0 2.1 supports HDR or high
dynamic range which expands black and white levels as well as color ranges
especially in bright and dark scenes you can learn more about HDR here but HDMI
2.1 takes the concept a step further
with dynamic metadata this allows the exact range of luminance
to be varied on a per-frame basis and
although the existing dolby vision HDR standard also supports dynamic metadata
it's a proprietary standard whereas the hdr10 standard is open meaning more
devices at lower prices
and of course HDMI carries audio along
with your video so there are improvements for your ears as well we'll
be getting a feature called enhanced audio return channel enabling
object-based audio schemes like dolby
atmos and dts x meaning each sound in the movie or show
that you're watching is encoded as its own specific object
instead of just having a limited number of discrete channels making positional
audio more realistic whether you have four speakers in your setup or 24
but all of this new stuff means HDMI 2.1 needs a larger pipe with
higher bandwidth 48 gigabits per second
to be exact which is over twice as much
as HDMI 2.0 and even faster than current
m.2 pci express ssds
there is bad news though in addition to buying a new tv a new
source device and new copies of all of your content you will even need new HDMI
2.1 cables to take advantage of the
higher resolutions just make sure that you don't get
hoodwinked into buying one of those thousand dollar silver ones from wire
world racing against the clock as a freelancer
challenging yes but with the growth of the internet
