I have 2 monitors , both at 1920x1080. However monitor 2 acts like an extended screen but that is not what i want . I want to create a 3840x1080 so both screen act like one.. So far i tried to create a custom resolution in nvidia cp 3840x1080 but when i press test the screen goes black. Can anyone help me out Im using Nvidia gpu - displayport and dvi.
