I've only used DisplayFusion. But the virtual displays don't work great. Full screening an app will full screen over the entire display. AFAIK this is a Windows limitation.Oh in that style there are things in both Windows and MacOS where you can configure snapping to act as 4 monitors so when you maximize something it will take a corner instead of the whole monitor. Havn't played with most of them out there but the software is there. My 4k monitors are only 28in so it is a size where I appreciate the sharpness and quality considering how much time i spend with text (source code and such).
