I don't really know how to explain this well. I have an external 27 inch monitor that I use with my MacBook Air. The 27 inch display and my MacBook's display obviously do not have the same resolution. In the display properties, you can drag each display up or down to align the edges of the displays. The problem is, with the resolutions being different, you have a "wall" between some areas of the displays. As in, when you go to move the mouse, the mouse will only cross to the other display where you have the displays aligned in the preferences. Is there a way to scale the edges of the displays so that no matter where you move the mouse between displays, it freely moves across? It can be annoying to have to move the mouse to the only area of the display where you can drag across to the other display. The optimal solution is obviously to have two monitors with the same resolution, but that's not really an option at the moment. Am I SOL, or is there maybe a third party software that does what I'm looking for?
