My TV's getting on a decade old. It's getting bad burn in around the corners. It's time is coming, and I'm prepared to replace it. In an ideal world I'd get a 4K HDR TV with OLED. Is it possible to get a high quality TV that doesn't have smart features? They're completely redundant for me so I'd hope that I could save money that way.
You could just not connect it to wifi/ethernet/internet.
A TV with 5g would still need you to buy a phone plan and a SIM card so you could just not do that.
