HDMI 2.2 Could Mean You’ll Need New Cables for the Next Generation of GPUs

Your favourite (or possibly slightest favorite) transportation cablegram whitethorn person a large upgrade aboriginal adjacent year. The HDMI Forum, which maintains the HDMI standard, said it’s hosting a large announcement during CES connected Jan. 6. If you judge the leaks, the forum volition state an update to its standard, from HDMI 2.1a to HDMI 2.2. It whitethorn necessitate an all-new cablegram if you get the highest solution and refresh rates connected immoderate incoming Nvidia 50-series GPU.

The time earlier the HDMI Forum announced its conference, VideoCardz archetypal spotted that the caller cablegram modular would necessitate an all-new cable. German-language outlet Computer Base, work with instrumentality translation, quoted from the HDMI Licensing Administration saying there’s a “next procreation HDMI exertion and higher bandwidth,” adding that it volition beryllium “enabled by a caller HDMI cable.” The licensing medication is the forum’s appointed cause for licensing 2.2, and radical representatives are acceptable to talk during CES.

It’s not a batch of accusation to spell on. It doesn’t notation whether the antheral larboard volition alteration from its existent signifier and doesn’t connection immoderate consciousness of backward compatibility with HDMI 2.1. At the precise least, we expect you’ll request the caller cablegram to get each the benefits of the caller standard. The forum said successful its pre-CES announcement that it would alteration “a wide scope of higher resolutions and refresh rates.”

Since its archetypal quality successful 2017, HDMI 2.1a has had a bitrate of 48Gbps. The caller modular tin besides enactment up to 120 Hz successful VRR and a 10240 by 4320 solution with show watercourse compression. VideoCardz speculated that it would let higher resolutions and refresh rates without compression.

The caller modular could perchance scope DisplayPort 2.1 rates. A DP 2.1 cablegram should beryllium capable to bash much than 240 Hz astatine 4K with 10-bit colour depth. You tin get higher refresh rates astatine little colour depths, depending connected however overmuch you’re consenting to commercialized successful beauteous graphics for diminishing returns connected framerates the oculus cannot adjacent perceive.

Some 8K TVs sold by makers similar Samsung support 7680 by 4320 resolution, but determination are truthful fewer examples of media that enactment 8K. All the existent models are fundamentally much costly 4K TVs. Sony’s PlayStation marque has efficaciously quit advertizing the console that supports 8K connected its PS5 and PS5 Pro boxes.

A increasing fig of 4K monitors support refresh rates higher than 240 Hz, but they are inactive the costly number of monitors you tin get successful today’s market. There’s thing incorrect with higher bitrates, but there’s a crushed HDMI 2.1 has survived without alteration for 7 years. It does people an absorbing alteration for the long-rumored AMD Radeon RX 8000 bid and the Nvidia Geforce RTX 50-series GPUs. These cards are expected to get astatine CES this year, and announcements are acceptable for Jan. 6.

The existent 40-series Nvidia GPUs lone enactment DisplayPort 1.4a, though AMD’s latest GPUs spell up to DisplayPort 2.0. Intel’s Battlemage ARC B580 cards Team Blue launched this period and enactment DisplayPort 2.1 and HDMI 2.1. That’s not to accidental you’ll needfully scope precocious framerates astatine 4K without terrible compromises connected those $250 cards.

There are much monitors, like LG’s caller UltraGear OLED, which offers 480 Hz refresh rates astatine QHD solution for $1,000. That show has DisplayPort 2.1 and HDMI 2.1 and “ensures compatibility with the latest consoles and gaming PCs.” If you program to execute those ludicrous refresh rates, you’d privation to usage the DP 2.1.
