I want to use an external monitor with my 2010 13" MBP. The MBP's screen resolution is 1280x800 (8:5 aspect ratio). Let's say I buy a monitor with a 1920X1080 resolution (16:9) aspect ratio. Does that mean that the image would be distorted on the extermnal display? Or can the graphics card simulataneously hadnle two different native resolutions?
