2nd display via GERT VGA 666 board/hat ?

[n1tr0]

As mentioned several times, we never support LVDS since the project starts. The reason is all new LCD panel are MIPI interface. On the GERT VGA 666 board, we don't have enough info and knowledge to know whether able to support.

All your documentation showed the Pine64 supporting LVDS. It's still shown in the the wiki and prominently displayed in your graphics. 
Thanks for the non-answer on the vga hat, it's good to know exactly what sort of show you're running before I commit to buying any more boards.
