>>7856733fix what? the color inversion? that looks awesome, I'd elave it, but from my memory of win10 it should be in the accessability options, one of the high contrast modes, or perhaps in display settings since it's only on one display
or if you mean the monitors being at different heights and/or correcting for the bezel in the middle, you can do the heights in the display settings menu, bezel correction you need a specific program for that like display fusion (pirate a cracked version, it's actually great for almost anything you'd want to do if you have more than one monitor)
