I’m with others. An offline ‘smart’ OLED is a dumb one, and with game mode they have lower input lag than any plasma I’ve used.
They’re just obsolete.
And yes, modern TVs have features you don’t need. Just don’t use them; they’re basically zero hinderence.
Maybe plasmas are okay if you find one at goodwill/eBay for dirt cheap, but that’s about it.
