My best purchase in the last couple of years was a 4k Sceptre TV from Walmart. Super cheap, good enough video quality and is dumb, just turns on to 4hdmi ports. That way I can just plug in whatever I want, or get a $30 roku and replace it whenever they update it to the point where it lags on basic menu navigation like my previous tvs.
Fuck all that bloatware, ad infested crap.
