I have a Macbook Pro that I use both at home and at work. At home when I'm using it as a laptop, the standard resolution of 1440 x 900 is fine as it's closer to my eyes. However, at work I plug in an external LCD so that I can dual screen and the resolution of the Macbook screen is a bit too large for my eyes.
Is there any way for me dictate a smaller resolution when I have an external monitor plugged in? Or is there an app that does this?
