The tip of HDMI could lastly be right here because of this new tech from China

China’s Shenzhen 8K UHD Video Business Cooperation Alliance has formally detailed an all-new audiovisual cable interface customary, which it aptly calls Common Function Media Interface (GPMI). Reportedly, the GPMI customary is being backed by 50 Chinese language corporations, together with huge names like Huawei, Skyworth, Hisense, and TCL.

As reported by Chinese language outlet HKEPC, GPMI can be accessible in two bodily kind elements: one with a propietary connector model (known as Kind-B), and one other that makes use of the open USB Type-C plug model.

Impressively, GPMI in its Kind-B kind is described as having the ability to help as much as a whopping 192 Gbps of information bandwidth, along with 480W of energy provide supply. The Kind-C variant can interface at as much as 96Gbps and 240W.

To place this into context, the newest HDMI 2.2 customary is able to a most output of 96 Gbps, and DisplayPort 2.1 customary is able to 80 Gbps. Neither AV requirements help energy supply of their base configurations. Thunderbolt 5, in the meantime, is able to 120 Gbps with as much as 240W of energy throughput.

HKEPC goes on to say that the Kind-C model of GPMI has obtained official USB Association approval, that means that this new customary ought to play good with the broader USB-C {hardware} ecosystem.

On paper, China’s GPMI seems to be the true deal

GPMI’s quoted bandwidth and energy supply speeds blow different requirements out of the water

On paper, the brand new GPMI audiovisual customary is extremely spectacular. On a specs-vs-specs stage, it outclasses different options like HDMI, DisplayPort, and even Thunderbolt 5. Theoretically, a single GPMI cable is able to outputting 8K video alerts, audio, energy, HDMI-CEC-like common management information, and networking info — a formidable all-in-one resolution if there ever was one.

The GPMI customary being backed by 50 Chinese language corporations is an enormous deal, too: establishing {hardware} requirements, open or in any other case, has traditionally confirmed to be an actual problem. We have seen tons of ‘format wars’ erupt through the years, they usually’re at all times a messy ordeal. After all, for GPMI to hit essential mass, Western corporations will undoubtedly should put their weight behind the usual as nicely, which is much from a given.

The bifurcation of GPMI into two totally different specs, one primarily based on a precedence connector, and one other primarily based on USB-C, can also be quite notable. It is unclear whether or not we’re formally witnessing the higher limits of USB-C as a expertise, or if GPMI Kind-B is extra of a play at disrupting the USB establishment.

In any case, I anticipate it to take a number of years earlier than GPMI-touting units hit retailer cabinets at a mass-market stage. It is unclear simply how costly it’s going to be to implement the tech into consumer-grade devices, or how keen non-Chinese language corporations can be to play ball. Within the meantime, HDMI, DisplayPort, and USB-C stay wonderful 4K requirements with sufficient headroom for almost all of technological purposes.
