Windows 7 Information
Display Modes D - 15
D
Display Modes
Single
Only one of your displays is used.
Duplicate
Duplicate simply shows an exact copy of the Main display desktop on the other display(s). This mode will drive
multiple displays with exactly the same content, resolution, refresh rates and color quality etc.
Extend
Extend treats both connected displays as separate devices, and they act as a virtual desktop resulting in a large
workspace. When a display is Extended, you can drag any icons or windows across to the other display desktop.
It is therefore possible to have one program visible in one of the displays, and a different program visible in the
other display.
