"The Midnight Modder"
I have similar setup on my 65.01 inch 4,001 Sony, apple, orange and banana TV's for air play.I built my own home theater PC years ago. I still use it once in a while when I want to do browsing on my 65 inch 4K Sony.
But, both the Sony in the Samsung in our bedroom have built-in apps so we use those most of the time now. I also have a couple Apple TVs that we use, mostly for airplay.
