Comment on HDMI 2.2 will be announced next month — and it may require a new cable

Kind of a crappy headline, like yeah you’re gonna need a new cable to achieve higher rates. This has been the case with every cable standard ever.

Whatever the spec brings, that mention of a new cable is a tidy reminder that like USB-C, not all HDMI cables are the same. It seems unlikely that HDMI Forum would change the port itself, so you’ll probably be able to use your old ones with the updated spec, and some might even support its higher bandwidth. Still, there’s always the chance you need fresh cables to get all of the new capabilities when the time comes.

All Display Port cables are compatible with all versions of the standard.

Subpar cables may not be able to take advantage of all the features present in a newer version. But if you bought a high quality cable for v1, it would still have full support for 2.1.

  That’s actually the same ad USB C, as I just learned. The pinout hasn’t changed, so if you have a good quality USB 3.1 cable it’ll work with 3.2x2 just fine

Yeah. There’s almost always a software update and high end (and sometimes surprises) gain significant bonuses.

But that has to lineup between both devices and the cable for it to actually manifest.

Pretty sure most “standard” HDMI you’d see first can handle 4k/120 tho. So it’s doubtful stuff will randomly already be capable of 2.2.

The article doesn’t seem to guess, but the 120fps is the weak point. I could see 240hz/4k or 120/8k and if you’re real lucky you could push something like 180 on a 2.1.

But just like, with very rare exceptions there’s no reason to be using HDMI for that type of stuff when other options already exist

It’s good to see the standard evolve, but it’s more future proofing than anything.

Like yeah you’re gonna need a new cable but also al new devices with new ports. And then hope this time the spec means is fully implementated.
