Try using the 1.4 cable with your 2.1 devices.
One could quibble over whether that is forward compatibility or backwards compatibility. (It depends if you define HDMI to mean the cable or the standard…) But the 2.1 compatible device will probably just silently fail without any hint to the consumer of what the issue is. Or, if you’re really very lucky, you’ll get some sort of degraded option.
Anyway
Fuck HDMI and their stupid standards that aren’t backwards compatible. Fuck their DRM supporting asses. These updates are usually just an excuse to close the analogue loophole for a month or a year, until it is broken again.
Their website speaks corporatese. Not immediately clear what their business model is.
That’s assuming both devices can successfully negotiate. Does not always happen.
