Just had my old dumb LG TV die after 9 years of working just dandy. I lack the desire to root around for a dead capacitor so I am currently in the market for an approximate replacement to act as the display for my Linux media center in my living room. I figure this is the right crowd for finding a non-invasive TV so my Linux machine can be the brains. I trust modern Tvs less and less.
Desired features
55"
Non terrible audio
As dumb of hardware/software as reasonably achievable
Really the best options I have found is to get a device running android tv which has the dumb tv mode. That combined with either not connecting it to wifi or using a pihole for any residuals is probably the most practical option.
