In the professional A/V integration world, it's normal for displays and projectors to have serial port interfaces that can be driven by commands from e.g. a Crestron controller or video switcher. Just not as much of a home/consumer thing.

Most LGs had a serial option, you can plug in a very specific USB to serial module in its USB port and then control it over serial with fairly generic commands.

Not sure if they still have this though. Mine does.
