HDMI Forum is unwilling to disclose the 2.1 specification for open-source (Linux): according to AMD, they had submitted a functional, HDMI 2.1-compatible driver [for linux?], which the Forum rejected. (www.heise.de)

I do not really have a body for this. I was not aware that this is a thing and still feel like this is bs, but maybe there is an actual explanation for HDMI Forum's decision that I am missing.

These days a ~10€ gadget can tell you about the electricity going through a USB connection and what the cable is capable of. I don't like the idea of basically requiring this to get that knowledge, but considering the limited space on the USB-C plugs I'm not sure anything is likely to improve about their labeling.

That's good enough for me, what they called and wee where can I get one?

I have something like this myself, it's useful for knowing the power delivery, but I'm not sure if that really helps when it comes to determining the speed of the data transmission that the cable/port is capable of, or other features like displayport support, or which version of USB4 it might be supporting (I believe they have the same power delivery, even though the transfer speed is double).
