There's too many variables between a Desktop and a Notebook/Laptop to give an exact solution, part of that is the differences in the video/graphics adapters and the sizes of the screens and their resolution capabilities. Also part of it is that the screens are Dynamic, not Static like a picture on the wall, always being refreshed or redrawn during use. Another part is the removal of customizations, usually with the twice-yearly Version Upgrades and possibly with a Build Update. And then there's the way third-party programs act with Windows.
