Color banding

Thanks for the information. I think I can explain this.

This is due to the panel rather than the DisplayLink compression. I think the panel is 18bit, rather than 24 bit, so the lower bits of the pixel color is missing, which is why you see the banding.

We output 24 bit color, but the panel is losing the lower bits, which has been chosen by the manufacturer. Under normal use, you would never notice this difference, but color ramps will show it up.
