For presentation purposes I want to mirror the device screen to a (very large) screen connected to a pc, so multiple people can see it at the same time.
What is the best way to do this. I have seen some apps but they either require rooting, signing up for accounts etc.. I don't mind buying some cable if they exist but chromecast is a bit excessive (need to switch device often and don't always run the presentation on the same pc).
Any suggestions or hints to get me in the right directions would be much appreciated.
