Can you connect the google chromecast to a projector?
If you could it would be very handy.
Can you do it with the epson 3020?
I just did some research and it appears that the chromecast doesn't play local files. It is only officially supported for chrome, netflix, and a few other things. That cuts down on its usability quite a bit.
With you and your friends set up, how did you get the audio to work?
