What is the correct way to shut down monitors

I have my computer monitors plug to a power surge protection strip that has individual ON/OFF switch for each socket. When I power OFF my laptop, what is the correct way to shut down the monitors? Can I leave the monitors in the ON mode and just turn the power switch of the sockets to OFF? Or should I turn OFF the monitors first using its little buttons, then turn the socket switch to OFF?  The second question is: is there a correct sequence to turning OFF the laptop and monitors? For example, should I turn the monitors OFF first, then select the laptop to shut down.  Or, should it be the other way round? What is the correct way to shut down when you have a laptop and monitors connected to a dock station, and the power cables for these devices are connected to a power surge protection strip that has individual ON/OFF switches for each socket.  If there is a correct sequence to shut down the whole system, then is there a correct sequence to power it up?  Thank you!
