I picked up this used 4k sony bravia recently and the thing is such junk. AndroidOS, seemed promising, but it has hardcoded ads on the homepage from whatever movies were coming out in 2015 when they were selling this screen, so much input lag, crashes constantly, can't even change picture settings as it will crash and reset to default. Sometimes it will just boot loop and not turn on until hard reset. Useless device today. Probably cost a thousand dollars when it was new I'm guessing, now it is ewaste.

Meanwhile my ancient 1080p panel still works, and I noticed I can't actually see the pixels from my couch so, ehh, I guess...
