start up the powerpoint presentation. Then start another occurrence of powerpoint. just drag that to the other screen. Not large full screen. make it a 16" higher. Resize it. that will work. Might even be able to drag a short cut to the other screen. that might work.
I am not to sure about this,since Once I tried doing a slideshow of photos on the microsoft Photo viewer and I dragged the window to the extended desktop and then maximized and when I selected slide show It began a slide show on the primary monitor.
I could be wrong,it might work for powerpoint.![]()
