It took the better part of a year, but Google Stadia is available on recent LG TVs. Anyone with an LG set running webOS 5.0 or 6.0 (that is, 2020 or newer) can use the cloud gaming service to play Assassin's Creed or Madden without requiring a media device or PC as a go-between. You'll need a compatible gamepad, but that shouldn't be an issue when the Stadia Controller and common console pads should work either wirelessly or through USB.
Not surprisingly, LG suggests one of its OLED TVs for Stadia thanks to the fast pixel response times, low latency and (for Stadia Pro subscribers) 4K HDR visuals. They're certainly not required, though, and it's arguably the lag from game streaming that will make the larger difference.
Stadia is available through the LG Content Store in all 22 countries where the service already exists. You probably won't buy a TV with Stadia in mind, but this significantly widens the number of sets where native support is an option — you might be more inclined to try it if the barrier to entry is that much lower.
