The UI on an LG from a year ago. Normally the bottom row of the first image would be a series of ads, but there is a way deep in the menus to opt out of them tracking your viewing habits which affected the ad space.
Something I had forgotten to mention before is the LG TVs don't have an option to reset the TV. Certain apps and system features (apps in app store disappear when deleting them off your home screen) can break where normally a reset will fix it. The only way to do a reset is to go into system information and opt out of their terms of service. If you're curious, opting out disables access to apps and using the TV for anything other than a monitor.
