The signal is transferred via WiFi - most modern displays have in-built wi-fi. First check if your monitor has it. If yes, check if the specifications match.
If no to either, you could use an HDMI receiver like
this one or connect a wi-fi receiver/router to a laptop, DVD player or Media player and connect that to the monitor.
It's not hard.
