Hi All! Long time lurker, first time poster. I apologize in advance if this question has been asked before. I searched but didn't see a specific answer. I just got a new MacBook. I am in the process of getting an external monitor for it. However, one thing has confused me - 16:9 vs. 16:10. I understand the difference, I just am not sure if the picture is stretched or if there are unused areas on the screen. I am considering a Dell S2409W monitor. However, it has an aspect ratio of 1920x1080 (16:9), not 1920x1200. Given that the MacBook supports 1920x1200, how will the picture appear if I connect this monitor to my MacBook? Does the picture get stretched and look strange? Will there be a black bars on the sides? Or does the video card adapt to make the picture look normal? I hadn't seen a clear answer on this previously and I really don't want to buy the wrong monitor in this situation. Thanks!
