How do different resolution monitors work together?

How does it work having a 1440p monitor and a 1080p monitor? As everything looks smaller on the 1440p monitor, when you move your mouse onto the 1080p monitor does it get slightly bigger?

Yes it gets bigger when you move to the 1080p monitor. A simple solution would be to run the 1440p in 1080p as long as you don't mind that. (and both screens have to be the exact same size)

Yes it works exactly like that. I will post a pic in a few min with 1920x1080 & 1280x1024 monitor.

There are two things at play here. The total vertical resolution and the vertical physical dimensions of the panels. 

 

If I take a print screen it matches the resolution but alters the positioning of the monitors. The right hand screen has 56 less vertical pixels which can be seen as the black bar that runs across the top.

 

Now I have taken a picture with my phone (sorry about bad quality)

 

 

You can see how the window is larger on the 1280x1024 screen even though it has less pixels so therefore should be slightly smaller than the 1080 screen. This is due to the right hand screen has a larger physical screen size so the pixel density isn't as dense as the 1080p screen hence it looks bigger. 

 

Also it isn't the picture but the top of both screen panels are at the exact same height (i.e the screens are level at the top). You can see how the 1280x1024 screen panel protrudes lower than 1920x1080 panel at the bottom as the 1024 screen physical screen size is larger.

The 27" monitor will have about a 108 PPI, while the 24" will be around 91 PPI, so the things will get very slightly bigger on the 24" monitor, but you don't notice it. It's more like having a monitor that's shaped like this:
