[Admin]

I don't get it. Why does it matter how much power it can take when all it will do is provide 1080p at max?

Wouldn't display ports still be a better option?

HDMI 2.0 already drives 4K at 60Hz and 8K at 30Hz with 4:2:0 chroma subsampling. HDMI 2.1 will drive 4K at 144Hz, 8K at 30Hz, and 8K at 120Hz with Display Stream Compression. It can also do 10K, probably 60Hz with DSC.

Why not just go with the new fiber HDMI cables? No need for additional power and, cable lengths as long as you need. They work perfectly for me as I keep my receiver 100 feet away out in my garage. No issues. They support 4k 120 / 8k / VRR / eARC, etc...

A media-changer from copper to fibre at either end would also need cable power, which is what this spec provides.

Yes, DisplayPort would be a better option. Everything should have switched to DisplayPort years ago. HDMI was designed for CRTs, and it's becoming a band-aided mess like USB. Look at this:

"the cables are unidirectional"

Then they are a design failure. Period.

I was going to ask the same. I'm confused at why there is no mention about hybrid HDMI cables.
Also confused at why people are giving their opinions about it without trying to use a Google search first. Even Amazon has SO many versions of the hybrid cables. None needing external power. I have one myself.

My investments in call support centers may just pay off yet...hold on Dad's on the other line

This would be a more exciting feature if my AV receiver could send enough power over the HDMI ARC output to my TV to power the TV to eliminate needing an electrical outlet and power cord up near the TV.

DisplayPort is a royalty-free standard controlled by a US-based standards organization.

HDMI requires royalty to use and is controlled by a large conglomeration of companies involved in multimedia.

If you were a for-profit company who not only makes TVs, but is also in this conglomeration, which sounds better?

Aside from needing copper to fiber, fiber has its own set of problems to overcome at the PHY layer. One could argue it's why optical SPDIF never really got an upgrade.

There's already enough power. There are loads of active fiber cables. Even some that are XBox certified for 4k 120hz.

what problems would you be talking about specifically? There are fully functioning HDMI 2.1 hybrid cables on the market that are plenty long enough. The poster said he has one that's 100ft long that works fine. And I have one that's 50ft long that works fine. The only thing that I can think of that people might complain about is that the video signal is only one way (source to display), but the audio fully supports eARC.

DP has power on both source and display sides which is good to support fiber connector. HDMI also need to provide power on display to help fiber based connection. MPO fiber cable is bi-directional and detachable, easy to change among DP, HDMI, DVI or USB.
