VMware Workstation 4.5
Virtual machines run faster in full screen mode.
If you want your VMware Workstation virtual machine's display to fill the screen so you no longer see the borders of the VMware Workstation window click the Full Screen button on the toolbar. You can also use a keyboard shortcut press the Ctrl-Alt-Enter keys at the same time.
To get out of full screen mode to show your virtual machine inside a VMware Workstation window again press the Ctrl-Alt key combination.
Linux hosts: You can switch between virtual machines without leaving full screen mode by using a Ctrl-Alt-Fn key combination, where Fn is a function key corresponding to the virtual machine you want to see. To find out what function key to use for a particular virtual machine, check the title bar of the virtual machine while it is running in a window.
Windows hosts: For similar functionality, see Using Full Screen Switch Mode.
Note: VMware Workstation does not support running virtual machines in full screen mode on dual-monitor systems.
