In addition to what James said, I’m reminded of the mechanism to change screen resolution in Windows XP: It automatically resets to its original resolution in X seconds, in case you can’t see the screen. This is so people can’t break their computers in one moment of weakness.
But you are absolutely allowed to break your computer in “one moment of weakness”; it isn’t even hard. The reason for that dialog is because the computer honestly, genuinely can’t predict if the new screen mode will work.
