I have a laptop with a 4k 17.3" display. When set to native resolution, 3840x2160, some programs do not display their dialog boxes and menus in usable form. In an attempt to correct this I have tried setting the display resolution to 1920x1080. Then setting the magnification to 100%. At 4k resolution it is set to 250%. When I change the resolution down the dialogs and menus become usable, however all the desktop icons disappear and the icons pinned to the taskbar all change to the same graphic, I can't tell what it is. If I change the resolution back to 4k the icons become normal again. Any ideas?
