Anyone got this to work succesfully? I managed to pull this off TO A DEGREE. https://comsysto.com/blog-post/force-hidpi-resolutions-for-dell-u2515h-monitor I can run it in a custom resolution 1140*855 (in that way, a virtual 4-pixel is roughly the same size as running the 15" 1920*1200. But no way can i make it run in 1024*768 (ipad native) also, there is no way to run it in portrait mode. I guess running it in one config is better than *nothing*, but still.
