That could be a possibility and I will look into it with my software soon.
But, as far as the image itself, it looks about the same as when projected from a 16bit DAC. Galvos are relatively slow devices so can't draw with great detail to begin with. Going from 16 to 8 bits doesn't have the same graphical effect as going from 16 to 8 bits on a precise monitor display.
