I'm running Win7 64 bit on VirtualBox and it only takes up half the screen. How can i expand it further?


To be able to change the screen geometry of a Virtual Box guest we need to install the virtual guest graphics driver.

This is done by installing the guest additions.

We can then set the Virtual Box guest into the following display modes from the View menu of the Virtual Box Manager or by a hotkey:

  • HOST + F Switch to fullscreen mode
  • HOST + L Switch to seamless mode
  • HOST + G Auto-resize guest display
