Recently I bought a new TV with hdmi 2.1. Until last week I was not getting that 2.1 ears output on my Dolby atmosphere lg gx speaker when connected via hdmi. I also saw sluggish TV performance attributed to my hisense TV. I debugged and with trail and error I thought may be my 1.4 hdmi is causing it. Soni bought bestos 8k hdmi cable that claims hdmi 2.1. Cable build is good when connected giving good sound output and see some of TV lagging reduced.now I need help in testing whether the cable is hdmi 2.1 or not. Any help to do so.? Youtube has videos, but I could not determine anything with it.

Tried , tv supports 60hz and 30fps. When played in youtube with video that says 4k 120hz 60fps i am getting 4k 60hz and 30fps. If video says 8k 120hz 60fps i am getting 4k 60hz 60fps max.
This is directly on the tv with earc connected to dolby atmos speaker with new new hdmi 2.1

Well, if one does not trust the brand/ seller or shopkeeper to be reliable or honest in mentioning the correct details or of the product functioning to the exacting standards then,

Alternatively, should one feel that the tags, labels, scan code on the product packing or whatevet is printed on the cable itself is good enough

Personally though, despite the claims of the said labels being non-reproduceable, something tells me that already a ten year young somewhere in Ulhasnagar, Maharashtra or in Shenzhen, Guangdong sheng has already maatered how to create counterfeit tags, codes, labels.

in all this is that, it isn't always going to be easy to have a display/ monitor at hand which can supported the rated resolutions and refresh rates of the current and future HDMI standards.
HDMI 2.1a is already at 8000 resolution at 60 hertz refresh rate (4K resolution at refresh rates up to 120 hertz).
Tough call finding hardware that might natively support 8K resolution at 60 Hz (4000 resolution at 120 Hz) and also give a rated maximum throughput of 48Gbps.
