I often wonder what happened to the irritating environmentalists who stood in the way of progress thirty years ago, while today millions of satellite boxes MUST be abandoned in favor of new technology and we never heard BOO about an "environmental impact statement." If the industry had tried to introduce HDMI in the 70s and 80s, the resulting trashpile of old but completely usable equipment would have inspired national picketing.
Today we just VOID the reality of millions of components, all in one fell swoop.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
