What would we call the device that is used to deliver the computer's image on the bigger electronic screen (like a PC monitor)? It is about the actual device that provides a visual output of every other device connected to it.
So literally it is an external monitor that commonly called a monitor, a TV, a screen or a display.
I believe that the word monitor stands for the part of the computer equipment that is connected to it with wires.
The word TV stands for the device that is used only for telecasting receiving.
A display is the part of a device that has a function of displaying the image. While a screen is the glass part of the display.
So what is the proper word for such a device?
