Usually, although displays advertise an accuracy of 18bpp, they are driven
either in 16bpp mode or in 24/32bpp mode, and the hw does the conversion
(likewise, a fair amount of flat panels are actually 18bpp in accuracy, and
do the 16->18 or 24->18 conversion on hardware). Are you sure your hw
exposes 18 bpp and not the more standard 16/24/32 ? I have a hard time
believing that.
