I connected my macbook pro to a dell u2711 and want to use it as a main monitor, how can I do that? it works as an extended monitor, when my macbook is on
system preferences --> displays --> detect Arrange displays as you want them, then move the menu bar to your external
And if you don't need the laptop's display you can use the clamshell mode: http://support.apple.com/kb/ht3131
No problem! The same thing with the plugging-in happened to me as well, I was cursing... should have read the article a bit more thorough.
yeah I had it working few hours ago, but the macbook was plugged in - didn't think it would make a difference
