The cable supports eARC (Enhanced Audio Return Channel). It is an Ultra High Speed HDMI 2.1 cable with a bandwidth of 48 Gbit/s, which fully supports all HDMI 2.1 features including eARC.
It says "3D Ultra high speed" which should mean 2.1 compatibility, but the HDMI consortium does not want (allow) more details, especially as it also allows HDMI2.1 for cables and devices that can only do HDMI2.0.
Hello, compared to the HDMI cables I used before, these are much smoother and I think you can bend them a bit. I don't know if there are HDMI cables with a rotating plug. Sorry.
Hoi. Maybe the 2.1 cable is faulty. I have also had these problems. There is a very good video about it from a dealer about HDMI.... Title: Hausmesse 2018 | What do mushrooms and red wine have to do with the HDMI standard? Very worth seeing. Then nothing is surprising any more.
Hello and good day, so, if I understand the question correctly, the "old" HDMI cable works between the Swisscom TV box and the TV. And the "new" cable does not.
According to my understanding, the PIN assignment for the cable is given and must work. So it seems to me that there is a fault in the cable or in the PIN contacts (HDMI plug) in the cable.
By the way, the HDMI cable between the Swisscom TV box and the Sony TV works for me. I also use the same cable between the TV and the Denon amplifier and that works too.
Conclusion: I would consider the cable to be "defective" and have it exchanged.
