└─>Map the console to the primary display device
In linux kernel since version 2.6.24 (release Date: 2008-01-24)  
If this option is selected, the framebuffer console will
automatically select the primary display device (if the architecture
supports this feature). Otherwise, the framebuffer console will
always select the first framebuffer driver that is loaded. The latter
is the default behavior.

You can always override the automatic selection of the primary device
by using the fbcon=map: boot option.

If unsure, select n.
