Like a monitor. They don't have anything smart, like TVs do.
My fear is that as usual if they become popular, they’ll just be yet another device used for more invasion of privacy and spying. They won’t stay dumb for long. ... Look what happened with TVs lol
EDIT: Also consider this monstrosity <https://www.samsung.com/us/monitors/smart/32-inch-smart-moni...>The solution here is to not use Windows, or to disable this auto-install feature if you do, not to avoid all external hardware the OS is capable of identifying (read: every device connected through any modern bus or I/O interface).
