So if anyone is interested I found the answer to my question. There seems to be two standards for LCD panels and there are these cheap converters for both of them.
They are made for laptops, and I am sure they work there. There was a post here about 15days ago asking about unsmarting TVs but it has been deleted. That got me thinking about this solution.
Seems like this is a much more important than any of the other discussions going on. How many results were tainted by the fact that they were compressing a dithered print image.
That is getting really hard to do. Seems like someone could make a market in controllers that replace the factory ones but hook to the factory sensors.
Many smart TVs require you connect to create an account. More might in the future.
