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 @Bellatone

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.

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! :-)
