Possible to set different resolutions on multiple displays?

If I do this:

Screen.SetResolution(A, B, true);
Display.displays[1].Activate(C, D, 60);

…that sets the resolution of both screens to a resolution of AxB, and puts a CxD window on the second screen. What I want is to set the fullscreen resolution of both screens separately. Is there a way to do that?

Actually, with more testing, what’s happening is Screen.SetResolution is only affecting the primary display. The second display stays at its resolution no matter what I do (and Unity thinks it’s 2880x1620 while it’s set in Windows to 1920x1080). There doesn’t seem to be a way in Unity to set the screen resolution of secondary displays (only the Rendering resolution, which is different from the actual native resolution).
