I work with Remote Desktops a lot. I was demonstrating Server 2012 from an RDP session last week and I couldn’t get the display to go full screen. I knew there was a super secret key combination to toggle back and forth between a window and full screen, but I couldn’t remember it. A quick “google” search on Bing didn’t show it. So here is a post that I hope helps when people search for this…

To go full screen from a remote desktop RDP session use the key combination:

<CNTL> <ALT> <BREAK>
