HDMI 2.1 has had a rather slow launch as well as silent , because although the specification was announced in January of 2017 and was launched in November of that same year, the availability of Products with this connectivity has been very limited.

However, the emergence of the first audio amplifiers with HDMI 2.1 support might not be the way that we connect our equipment to a high quality sound system, because a bug in the Panasonic HDMI 2.1 chips is causing black screens.

As is known, a bug in the aforementioned chips prevents video from being transmitted at resolutions only compatible with HDMI 2.1 , such as 4K 120 or 8K 60, both with HDR , so that although we could get sound in our speakers, the screen that is connected to the amplifier will go black due to this problem.

At Heise.de they have been able to verify that both the NVIDIA GeForce RTX 30 Serie s like the Xbox Series X suffer from this problem when connected through an amplifier with the aforementioned chip, whereas if the amplifier is removed from the chain and connected the sending device directly to the TV, problems disappear immediately.
