Has the usual USB port and mentions HID in the documentation does seem to work. There are so many like this that it would be improbable that anyone would make a list.
That out of the way the usual keyboard I suggest i the Logitech K400 Plus.
And there's a big topic we must address. Adding a keyboard to a Smart TV does not turn it into a PC. The apps are not open except for what the makers decides to give us (there is a rare exception to this) and some apps just don't work as expected with the keyboard. I found the YouTube app to be all over the map.
I am looking for the best Smart TV operating system that also works with a keyboard easily. Names and models if available
