I mainly want to be able to adjust the split of the picture-by-picture mode. By the default, the monitor splits the display 50-50 between the two inputs. It can, or at least should according to the official documentation that I currently have open in another tab, change that ratio but apparently that can only be done through the control software.
edit: nvm, turns out it can only adjust that ratio when connected to the same computer. And only on windows and mac. Meh.
