Black screen resolution caused by incorrect MAC settings

In "display" of MAC lion 10.7 system preference settings, if you click the wrong resolution, some will prompt that the user may not be able to display, and some may choose to immediately black screen, in this case, restart to enter the Security Mode of the Mac, which can be displayed normally, but enter the normal mode again, it still cannot be displayed. This is not as good as windows. There is indeed no good way to solve this problem. The method for deleting windowserver plist files circulating on the internet is useless in lion.

I also accidentally discovered a method: Install the Free Software switchresx in safe mode. After installation, the resolution will be reset and then return to normal mode, it will be displayed normally. In addition, the software package replaces the shortcut key for restoring display settings. If you accidentally encounter another tragedy, you can use this shortcut key to reset it.
