It's unreasonable to expect the average person 
    on the street to be an expert on the subject and 
    to have fully researched everything before walking 
    into a store, so if the TV's packaging doesn't say 
    anything about the subject, how do they learn?

The solution depends on who you ask.

Some would say that it's up to the consumer to be educated. Like you, I don't think this is realistic. It's not realistic to expect every consumer to become an expert in the nuances of every single thing they might buy.

Others would say that if it's really important to customers, we'll vote with our dollars and demand alternatives to the current situation.

Some would say that the government should ban the practice or at least require some sort of very clear disclosure.

What would you like to see?

The vast majority of people just don't care and want the most TV for the least money.

It's a "tyranny of the majority" kind of situation. For TV manufacturers, it's not worth catering to the tiny minority of customers who think like us.
