If you have Windows Phone 8.1 and want to display it’s screen during a presentation try the Project my Screen feature. You’ve probably heard of this feature, if not Cliff Simpkins has details on how to install and use the feature.
Essentially you install an application on your computer and enable the feature on the phone. Run the desktop application on the computer. When you connect the phone to the computer via USB you see this prompt on the phone.
If you choose Yes, your phone screen is shown in the desktop app (and can be shown on a conference projector).
Did you know the connection is bidirectional?
I’ve been using this feature for a couple days but I had no idea that the connection went both ways. I have a touch screen laptop. I can touch the image projected on my laptop screen and remote control the phone. Nice!
Shout out to Morten Nielsen for tweeting about this “feature”.
