For two way communications you would need a display that supports Samsung’s MDC Protocol. These are typically signage/business/professional displays. Mine are ME Series and support MDC Protocol which is very useful for automation because I can query status of various things, keeping in kind that the status command supported when the TV is off is the Power Status command.

A helpful program for testing with either ExLink codes or MDC Protocol codes is DockLight ([Link:])
