[Monitor] Live display of chat using monitor

Is it possible to have a monitor display what's happening on a Computer live? I would use it for the chat feature, in order to display a live chat feed.

If there is no way to do this, is there any other way to display chat on a monitor live?

Thanks, I'm just really new to this.

Using the command line command monitor requires the following arguments:

<Name> <Program> <Arguments>

How do I set the name?
I've tried anvils and all, I just can't figure it out. Maybe the solution is very simple and I'm just stupid, if so let me know :)/>

The name is either the side of the computer the monitor is attached to, or the network peripheral name that appeared in chat when you activated the wired modem attached to it.
