In looking at the Sharp LH7400 User Guide, they only talk about bit-per-pixel modes 1, 2, 4,8 & 16 for the Color LCD Controller. I am assuming that this means that the on-board LCD controller cannot do more than 16 bpp. Is this correct?

If you need to do greater than 16 bpp, what are the options? Do you need to bypass the on-board LCD controller and use an external controller chip to get better than 16 bpp?

Thanks for the info in advance,
Frank
