Further explanation is provided here to avoid misunderstanding
18bit= single channel & 6 bit color
24bit= single channel & 8 bit color
32bit= dual channel & 6 bit color
48bit= dual channel & 8 bit color
For example, the pictures above selected setting for 1024x768 panel with a single channel 6 bit color .
Resolution from 1440 x 900 to 1920x1200 must be dual channel data transmission
So choose 18/24 Bit (Single channel) can't light the screen.
