When we talk about displays , we mean how physical screens are detected by PC as virtual displays. "display" defined does NOT equal to physical screens.
You can check it by: "right click on desktop" >> "click on screen resolution"
For example: 2 screens connected PC are merged to 1 desktop by graphic card. PC detects 1 virtual display , but there are 2 physical screens.
