So I have two monitors, my main is a 37" 16:9 1080p screen (my old TV), and the other is a 20" 4:3 LCD. Now by a nice coincidence, when the 20" one is rotated portrait, it's height is about the same as the 37" LCD. Since they line up, I'd like the mouse to be able to move back and forth along the entire height of the 20" one, but because it's 1600px high and the 37" is 1080px high there's a solid 1/3 of the screen that the mouse will just not go past.
I know it's a minor issue, but it's a bit annoying. Is there any program I can download or a setting I can change that will make 100% of the edge traversable rather than limiting it to the height of the shorter side pixelwise?
