intel-virtual-output - Utility for connecting the Integrated Intel GPU to discrete outputs

 "intel-virtual-output [<remote display>] <output name>..." 

intel-virtual-output is a utility for Intel integrated graphics chipsets on hybrid systems. The tool connects local VirtualHeads to a remote output, allowing the primary display to extend onto the remote outputs. The xf86-video-intel driver is part of the X.Org and Freedesktop.org umbrella projects. Details on bug reporting can be found at https://01.org/linuxgraphics/documentation/how-report-bugs. Mailing lists are also commonly used to report experiences and ask questions about configuration and other topics. See lists.freedesktop.org for more information (the xorg@lists.freedesktop.org mailing list is the most appropriate place to ask X.Org and driver related questions). intel(__drivermansuffix__), __xservername__(__appmansuffix__), __xconfigfile__(__filemansuffix__), Xserver(__appmansuffix__), X(__miscmansuffix__)
