There's a serial port and what looks like an RJ45 port, but no USB port.

The Serial port is RS232, and there are a set of commands you can send to the set to perform a remote/front panel lockout. We used to do them with RCAs that were used as monitors in schools.

You'll need the LG terminal program or a really good understanding of how to send specific commands to the set via PC.
