In display settings, you can change the orientation of your displays in relation to one another. However, one of my displays (The inbuilt display of my old macbook) is significantly smaller than my other monitor (Samsung T37F) but it shows the laptop screen as being twice the size of the desktop monitor when the sizes are really the other way round, and the laptop is half the size of the monitor.
My question is, if there is a way to change this, how can I do it.
