Getting Display modes mac os X

Question

CGDisplayCopyAllDisplayModes提供的显示模式数量比系统首选项窗格中显示的数量更多。.我只希望那些显示在系统首选项->显示下的显示模式。我如何仅获得那些显示模式？

Answer 1

Checking each mode with CGDisplayModeIsUsableForDesktopGUI() will allow you to filter out modes which are too low-resolution, or have too shallow of a color depth, to be used as the "desktop" resolution. That should eliminate most of the truly wacky modes.
