We have MINI ITX motherboard, This board supports multiple display option VGA, LVDS..For this configuration we prefer only LVDS. Currently, we are migrating from LINUX to WINDOWS,Initial installation process does not have any hicups. However, when the installtion completes and ask for a reboot. The system by default switches to VGA and there is no display on lVDS. For this we have to connect an VGA display and complete the rest of the installation and set "Duplicate Desktop on Projector" to get the LVDS back.
We definitely do not require any VGA interference during the installation process. Need some guidance fro enabling /CLONE display mode from the time of installation.
