The GPIOs can only be used on designs that have firmware configured to
use them. You'll have to contact sales at displaylink.com if you wish to
build your own firmware - this would also require that you build PCBs.
The DL1x5 is only specced to operate down to 25MHz, so 320x240 is a bit
low for that - there is no guarantee that the chip would sucessfully
operate at a frequency as low as that.
