I know so little about electricity it's not funny. I have a redundant Acer monitor that is powered via a lead that connects it to a computer. I've also got an old Dell computer which came with a monitor that you plugged into the wall for power. There isn't a socket for me to connect the Acer monitor to it for power. Can this monitor be used with my Dell and if so what do I need? Could I for example power the monitor via a different lead plugged into a wall socket?
