There is that video wall processor world I know a little about. With those you can take 4, 9 and maybe more TVs to make your own video wall. There are some than call those video servers such a thing and there was a company that claimed to improve standard definition but beauty is definitely in the eye of the beholder.
I'd forget about such things.
Just purchased a 65" Panasonic VT 50. Waiting for it to be delivered. Would like to be able to max out all of its potential. New to the tech world. Any opinions?
