Or a security feature like Secure Boot could be used for such purposes. Samsung also offers the possibility to remotely turn off TVs worldwide. The feature is called TV Block, and it recently came to light.
[German]The encryption method StartTLS, which can be used in network communication, especially for e-mails, has a number of vulnerabilities that make it possible to break open communication by stealing access data, for example.

At least the manufacturer Asus has now apparently released a solution in the form of a vBIOS update for the TUF 3080 TI.
