How the switch via screen edge works if it doesn't need any progs installed on your computer? Doesn't the absolute mouse coordinate space need two identical monitors? And how it figures out when you are at the edge of the screen?
Maybe it detects when the mouse is moving, but a given coordinate is always the same. So you reach an edge, and X is always the same, while y has some variability. So this means time to change to the other monitor.
It doesn't, the coordinates are always reported 0-32767 and the computer does the heavy lifting of mapping it to the physical screen geometry. This also takes care of the problem with different resolutions.
