In the Datasheet the 0xFC is described as "storage" does it mean there should be the settings for the Graphic like VBT? I did not find more information abaout GCT and how to implement it. The board uses sdvo->vga for the output, the second board uses sdvo->DVI and LVDS but there is always a black screen on each output interface. So i think there is wether a VBT not a GCT.
