Wiring up your TV is a reasonably cut and dry operation , and thanks to onward motion in A / V technology , there ’s middling much only one cable you ’ll take for any newfangled home theater component , and that ’s HDMI .

The all - in - one digital connection has created a profusion of way to make hardware ready for the expanding A / V globe around us , allowing for innovations like 4 K Ultra HD and8 K resolution .

But as we move through generations of unexampled HD standard , the character of HDMI cable we need are unceasingly interchange — HDMI 2.0 begot 2.0a , then 2.0b , and now 2.1 . One of the most common HDMI standards that still remains is HDMI 2.0b . HDMI 2.0b was built on HDMI 2.0a , which tack a few feature onto the previous HDMI 2.0 , includingHDR . Designed to vastly ameliorate the contrast between light and dark-skinned paradigm for a more realistic motion picture , HDR is now moderately standard in most new television set .

In this article , we ’ll excuse all the marvelous things you’re able to do with your menage theater thanks to HDMI 2.0 , while also touch on the welfare of HDMI 2.0b — which isextremelysimilar to HDMI 2.0a . In fact , the two are fundamentally the same , except that HDMI 2.0b add financial backing forHybrid Log - Gamma(HLG ) , a newer HDR technology intended for broadcast applications .

And guess what ? HDMI 2.0b does not require dissimilar cables than what you ’re already using , unlike HDMI 2.1 .

The basics

As we’vewritten about antecedently ,   the master ground for the permutation to HDMI 2.0 is that 4 chiliad Ultra HD televisions postulate much more bandwidth to realize their full potential . Since 4 K Ultra HD is four time the solvent of 1080p , the former HD touchstone , it requires   more throughput to handle extra data going back and onward . mess more .

HDMI 1.4 support 4 cat valium resolutions , yes , but only at 24 or 30 frames per second ( fps ) . That works fine for movies but is n’t utilitarian for gaming and many TV broadcasts , which demand 50 or 60 Federal Protective Service . Also , HDMI 1.4 limited 4 jet Ultra HD depicted object to 8 - second color , though it is capable of 10- or 12 - bit colour . HDMI 2.0 fixed all of that because it could address up to18 gigabits per secondly —   plenty enough to allow for 12 - scrap color and telecasting up to 60 frames per second .

Ultra HD was one thing , but current idiot box point to bollix our minds with even higher image realism , by create more intense whites and inglorious blacks — it ’s like Tide for your TV , making everything more vivid , which is what HDR is all about . TVs from Sony , Panasonic , LG , Samsung , and Vizio all tout one version or another of HDR technology . HDMI 2.0b adds yet another flavor to the HDR card , with support for HLG , the interlingual rendition of HDR that is favor for hot video program .

Don’t throw away your HDMI cables

As mentioned above , HDMI 2.0b changes nothing about the sizing , human body , or wiring of HDMI cables . Should you twine up getting gadget that are HDMI 2.0a compliant , your existing cables will work just ok . And since HDMI 2.0b is backwards compatible with older HDMI versions , you ’ll be able to connect your old Blu - beam player and/or AV receiver to a blade - new HDMI 2.0b - equip 4 kelvin Ultra HD TV with perfectly no job .

What’s new with HDMI 2.0b?

Object-based surround sound

The update to HDMI 2.0 in 2013 made possible 32 channels of uncompressed sound . If that sounds like overkill , well … it might be for some . But do n’t secern that to the surround strait gurus   over at Dolby or DTS . The latestDolby Atmos surround formatis capable of 64 epithelial duct of surround in the theatre , which breaks down for your dwelling house theater to let for 11.2 - channel audio frequency . It ’s called object - based surround sound , and it allows for singular objects to be mixed so that they move throughout a   hemisphere of multiple speakers wholly autonomously .

Dolby ’s version includes configurations that tender two to four speaker that can fire vocalise down from the roof , or leaping sound off the ceiling from the floor for an epic explosion of immersive   audio . There are several receiver from the likes ofMarantz , Onkyo , andPioneerthat are Atmos compatible , as well as especially designed speakers from Pioneer and others that mount speakers on top of their storage locker to shoot sound off of your cap . Wondering if your home theater frame-up supports Dolby Atmos ? Check out our full guide togetting great Dolby Atmos sound .

Not to be surmount , DTS also bring out its own organization for   the future of physical object - based surround sound , called DTS : X. The system is designed to be compatible with many of the same component as Dolby Atmos and , for now , also offers a uttermost of 11.2 channels . However , DTS :X allows for even more flexibility than Atmos , including the power to practice up to 32 different available speaker conformation . Is it a coincidence that the available speaker unit shape for DTS :X equate the same number of channels that are permissible by HDMI ’s current protocol ? We think not .

In case you didn’t know, your remote is magical

The switch to HDMI 2.0 brought standards that required the inclusion of certain control feature of speech for the standard language that machine mouth , prognosticate CEC ( Consumer Electronics Control ) . As such , your remote is belike able to control a whole lot of other devices , without necessitate you to whip out an encyclopedia of four - fingerbreadth distant restraint code and plug in a bunch of push combination . With CEC , connected devices can also issue command to your idiot box . A machine-accessible Chromecast , for model , can tell your telecasting to turn on and switch to the correct remark , plainly by draw content from your smartphone to the Chromecast , no need for your remote at all .

Another progression in the protocol , theHDMI - ARC port wine , immensely simplify audio frequency connexion . In the past , if you want to send audio from your telecasting to your soundbar or A / Little Phoebe receiver , you need an optical cable television ( in an idealistic world ) or at minimum a set of RCA analog cables . Using a TV ’s HDMI - ARC port , which nearly all new television set come with , a undivided HDMI cable can receive audio frequency and telecasting from an outside generator , and audio back to that equipment , which is why ARC fend for Audio Return Channel . It ’s a bounteous convenience if you have a streaming gadget connected to a petty HDMI port , or if you ’re using one of your idiot box ’s built - in apps .

What else can it do?

While it ’s been around for a while , it ’s of import to eff that the HDMI 2.0 update made possible simultaneous delivery of dual video recording stream to multiple users on the same screen — just imagine what that could do for video game ! And although HDMI 2.0b is just a pocket-sized update , when HLG comes out en masse , the useable image advancements could make the update sense a lot bigger .

There you have it . We ’re several class in and HDMI is going strong , and the organisation ’s innovative pattern will proceed to allow us to rock out with fresh technologies and the latest hardware while holding onto the onetime .
