Make it OLED, dumb TV, instant on, Apple TV box plugs in. Separate box with front facing ports that connects to screen with one cable. A remote designed by someone who thought about it for ten seconds (why do modern TVs have dozens of buttons no one ever uses?).
This entire market is in desperate need of someone to make something decent.
The best available option today is LG and it’s still laden with ads and takes a few seconds to boot up.
