Is there any command in Ubuntu to detect an HDMI monitor? I have tried ddclient but it's not working.

The command I tried:

ddclient -p m/> Power control/

@BhumiShah ddclient is a client for dynamic DNS services, it has nothing to do with monitors... Were you by any chance looking for ddccontrol?
