I want to ask here whether LG allows or provides the application that we have created to be used as the default display
Currently, there is no API provided to automatically launch an app when the TV is turned on. Only the user can launch the app. Thank you.
For LG webOS TVs, third-party applications cannot be set as the default home screen. However, it is possible to configure the app to auto-launch in kiosk or signage mode, allowing it to display automatically when the TV starts without replacing the system launcher.
