I think it was something like: def get_display_number(self): if display_ctrl.GetSelection() < 1: return str(self.display_ctrl.GetSelection() + 1) else: return str(self.display_ctrl.GetSelection() + 1) + ",1" So, if the screen number is > 1, instead of -d n, we get -d n,1 to use the first screen LUT. But I think it is better to add a combobox to choose the screen to use for the LUT, and build the -d param from the 2 screens comboboxes. Better, you could make a test to check if all screens support a LUT; if not, enable the additionnal combobox (and only in this case).
