It took almost a year, but Google Stadia is finally available in newer LG TVs. If you have an LG TV running on webOS 5.0 or 6.0 (which is 2020 or newer), you can use Google's cloud gaming service without using a media device or PC as a go-between. You will need a compatible gamepad, which can be a Stadia Controller or other standard console pads.
LG recommends you use it with one of its OLED TVs, citing fast response times, low latency, and 4K HDR visuals (at least for Stadia Pro users). But you can still use its other compatible televisions just fine. You can access Stadia through the LG Content Store in the 22 countries where the service exists.
