I am looking at the new mbp, but I have a quick question. I have noticed that the aspect ratio is 1440 by 900. Which i think, even for design will be ok for me on a 15" screen. When i plug the mbp into a larger monitor, say 24" is there any way to make the image on the monitor, 1920 by 1200. Or am i stuck at the 1440. Thanks in advance.
