Does anyone know if using an HDMI cable labeled "High Speed" or "Ultra High Speed" is a better option to use with the Sonos Arc Ultra rather than the one included?

The video that is sent is the Sonos screensaver.
And I finally found the 720P note.
From the above topic:
Hi
Contrary to apparently popular belief, the cable for carrying audio to your audio device does not need to be capable of carrying 4k or 8k video. The bandwidth requirements for carrying even uncompressed audio is nothing as compared to 4k video - only a HDMI v1.9 cable is required for eArc audio. The cable does carry video, but it is a 720p static picture in case you ever select the eARC/HDMI-ARC input on the TV.
Most Arcs/Arc Ultras are mounted immediately below the TV, so yes - the supplied cable is entirely sufficient in the majority of cases.

The Sonos HDMI cable supplied is already High Speed with Ethernet and can carry all supported audio formats.
And I suspect the amount of ‘speed’ necessary for an audio (ARC) connection is significantly lower than for a video connection.

An Atmos music bluray will get up around 6MBps or so from what I’ve seen. An HDMI cable should handle even that no problems.
The supplied cable is appropriate for sending audio to the soundbar. Ultra high end cables are much stiffer and more likely to cause physical connector damage while you are struggling to install everything.
I think I saw a note somewhere that the TV to Arc cable only carried 720P video.
I’d worry a lot more about quality and not numbers. Stiff, off-spec ends, poor plating or internal soldering all far more important to avoid.

I have no idea what you just said
What he said is the cable supplied by Sonos wasn’t designed to carry high bandwidth video, but enough to handle the bandwith for eARC support, which is a different set of pins in the HDMI connection.
Not sure I agree, I don’t recall seeing that note. But I do agree that the connection to the HDMI ports is important.
Apparently eARC connections on both ends is vital for the best enhanced connection, whether it is delivering video or audio. But the quality level of the HDMI cable itself must also play a factor. That's why I asked the question.
Any HDMI cable of HDMI 1.4 (I’m pretty sure) has the bandwidth necessary to carry ARC or eARC on that part of the cable. Many manufacturers advertise bandwidth for video, but none that I’m aware of for audio.
You could probably get a lot of data at Wikipedia on the various specs for HDMI.

So HDMI 1.4 must be ARC, and HDMI 1.9 must be eARC. I need to remember that.
Remembering is a really good option compared to trying to find old topics here on the forums! :-)
