How do I manage my system settings
Open your display settings with ‘Menu’ button. Select the ‘Advanced Settings’ network menu option. From here, select the ‘System Settings’ menu option.
This opens to allow you to set: your system language, the current date/time, manage your sources, or select the ‘more’ option for addition options.
Select the 'more' option.
The ‘More’ menu allows for additional configuration, setting: your menu timeout, toggle your standby mode LED, review your software upgrade, adjust your country, toggle Auto Display Off, mange CEC, manage your CEC power on, and manage USB Auto Play.
