I don’t think that’s correct. You won’t be able to use 4k60hz with 1.4 that’s for sure, but unless the device only supports like 60hz, it should work if you lower it to 1080p 24hz or whatever fits within the 1.4 bandwidths parameters.
It doesn’t always happen even with both devices being 2.1 and the cable being 2.1, lol. But stating that HDMI revisions are not backwards compatible just simply isn’t true.

That’s assuming both devices can successfully negotiate. Does not always happen.
