I wanted to share my chromebook screen with student PCs. But why not just use a projector to share the screen? Engagement. If my screen is shared on their device, they can't be off task very easily. If I am projecting it, they may be checking email, playing games, or surfing the Web. So screen sharing is a great alternative. Simple, right? Not so fast.
The obvious choice would be a Hangout on Air with screen sharing.
BUZZZZZZZ! Incorrect - not allowed in our GAFE domain.
Okay then, use the Chrome Remote Desktop app from the Chrome Web Store.
BUZZZZZZZ! Incorrect - it allows sharing to a Chromebook, but not from a Chromebook. And all computers involved must have the app installed.
Fine. Use one of many free screen sharing apps available in the Chrome Web Store or online.
BUZZZZZZZ! Incorrect - you get what you pay for. I tried almost every freebie I came across and they are all dicey at best. They proved to be unreliable, incompatible with Chromebooks, or blocked by our school. And I'm not chucking out a monthly fee to share my CB screen.
Mirroring360 - The best solution I have found.
But I think I found a winner: Mirroring360 is designed to wirelessly share a Chromebook, iPad, or iPhone screen with any PC or Mac. It requires downloading software to the PC/Mac and installing two apps: Mirroring360 Receiver on the PC/Mac, and Mirroring360 sender on the device.
While it took me a few tries to get the screen sharing to work, I am happy with the results. I used the free trial to test it. So, no, Mirroring360 is not free. But here is the good news: the cost for a perpetual (forever) license is only $10.99 through October 31 (2014). The regular price is $29.99. The apps are free; the price covers the downloadable software for the PC/Mac. For that price I'll pay out of my own pocket if I must!
