I'd like to refine my question to you Gerald... How can I get 24-bit color with the BBB via either HDMI or LCD (assuming the LCD I wire up is a 24/32-bit color panel)? I thought the TI spec indicated the BBB could drive true-color but all I can manage to get out of the BBB is 16-bit color regardless if I use HDMI or the LCD from 4D Systems.
