And as the code is manufactured in the HDMI chips and not replaceable or reprogrammable then it's cast in stone what the HDMI chips and interface can do.
Somewhere in the lab there is such a thing but in production gear such as TVs, it's strictly what they tell you it is.
Let them be. Let them believe what they want.
I'm currently having an argument with a friend of mine regarding HDMI input / output.
It is my understanding that an input and an output are not the same piece of hardware and are intended to be used as receiving and sending information respectively.
Now my friend is telling me that they are, in fact, the exact same and the input and output can be reversed through 'code'. I can't find any information that supports that ability to specifically make a HDMI input act as a HDMI output, but my friend is adamant that the ability to do this exists.
Could anyone help clear this up please?
