You can do it with lisp ( ActiveX ), adjust the size of the whole Acad program window, but I don't know yet how to get the true size of all screens attached, and I don't see how to move the acad program window where you want it yet. One would adjust the ' Height ' and ' Width ' properties of the Acad object ' (vlax-get-Acad-Object) '. You might also have to change the ' WindowState ' property.
