Seems unnecessary surly just plug in a raspberry pi into the HDMI port and never connect the TV to internet u can probably flash some version of android TV onto the pi and all set.
The samsung TV that I bought for my son had this annoying overlay thing that pops up when you turn it on that shows all the different inputs and nags about various things it thinks are wrong with the world. It is plugged into an Nvidia shield that we do most things on, but you can't use the shield until the overlay calms the fuck down and disappears.
It'd be great if you could just have the thing turn on and display an input like our older TVs do.
Damn I have an old school amp with the surround sound speakers that has a single hdmi output that everything goes through so my tv never complains cos as far as its aware its just a hdmi input.
