No option to duplicate monitors on Windows® 10 Anniversary Update

If you don't see an option to duplicate a display to the externally connected DisplayLink display, this may be due to the graphic driver for your primary graphics card being out of date.

Please make sure to update the driver from the Intel, AMD, or NVIDIA website, as the latest version may not be available from your computer manufacturer.  The ability for a graphics card to duplicate its display to another graphics card was not a mandatory feature for graphics card drivers until the Windows 10 graphics driver model.

Therefore, some older graphics drivers, which have not been updated for Windows 10, may not support duplicate mode with DisplayLink. Examples include Intel Ivy Bridge and Bay Trail graphics drivers for Windows 10. A workaround to this issue is to uninstall the graphics driver so the system uses the Microsoft Basic graphics driver, which supports mirroring with DisplayLink.
