+## Service `vizio.update_setting`
+
+This service allows you to update a setting on a given Vizio device. You will need to know the type of setting and the name of the setting to call this service. You can determine this by using the SmartCast app and going to device settings for your target device. The setting type is the lowercase version of the first menu item you'd select (e.g., display, audio, system), and the setting name is what you see in the app, but spaces are replaced with underscores and it is also all lowercase (e.g., AV delay would be called `av_delay`).
