Adjust Full Screen Settings
You can customize how Windows appears and behaves when in Full Screen mode.
To access Full Screen settings:
Choose Which Full Screen Mode to Use
By default, when you switch Windows to Full Screen, Windows is set to operate in the OS X native Full Screen mode. This means that it becomes displayed on a separate space and when you move the mouse pointer to the top or bottom of the screen, the OS X menu bar or Dock appears correspondingly.
If you don't want the menu bar and Dock to appear (for example, when playing games or working with Windows applications in Full Screen), clear the Use Mac OS X Full Screen option. In this case, Windows will work in Full Screen designed by Parallels. In this mode, a separate space won't be allocated for Windows and the OS X menu bar or Dock won't appear when you move the mouse pointer to the top or bottom of the screen.
Set Actions for Screen Corners
Parallels active screen corners allow you to exit Full Screen, display the Mac OS X menu bar and Dock.
If you set Windows to operate in Full Screen designed by Parallels, Parallels active screen corners become enabled by default. If you prefer Windows to operate in the native OS X Full Screen but want to use Parallels active screen corners instead of Mac OS X hot corners, select Active Screen Corners.
To set which action is performed for a screen corner, select one of the following from the menu near that corner:
Note: If you're using Mac OS X Snow Leopard and active screen corners such as Expose or Screen Saver are set in Mac OS X preferences, those settings take precedence over Full Screen mode active screen corner settings. You must deactivate Mac OS X active screen corners to enable Full Screen mode active screen corners. See Mac Help for more information.
Scale to fit screen
Using the Scale to fit screen menu, you can configure how Windows is displayed when working in Full Screen:
Set What Shows on Displays Connected to Your Mac
If you have a second display connected to your Mac, by default when you switch to Full Screen mode, Windows is displayed on the primary display and Mac OS X on the secondary.
You can choose which display Windows is shown on by dragging its window to that display and then clicking the Full Screen icon .
To extend Windows across all your displays, select Use all displays in full screen.
Allow Windows to set display gamma
If you're using Windows to play video games, Windows may need to temporarily change your Mac's display gamma setting to properly display different visual effects. To allow Windows to change gamma settings, select Allow Windows to set display gamma.
Note: To prevent unauthorized changes to Full Screen settings, click the Lock icon at the bottom of the window. Once locked, an administrator's password is required to make further changes.
