I've seen around people talking about using their goggles for other things like watching movies. 

Now as I can't fly at the moment the weather is crap I was wondering what everyone's alternative uses for their goggles are? 
And instructions on how you are getting setup so I can copy.

Depends on if your FPV goggles has video output... some of them have HDMI outputs, makes it plug and play to a computer, or XBox, just like any normal monitor screen, for example the Dominator V2/V3/HD, and the Headplay of course.

Cheaper goggles don't have this... such as the predator, you cannot connect it to a PC very easily.

I have watched films on my Dominator. It's a great experience
