I understand this is possible on a mac with an ipad, and I had high hopes for chromecast being able to do this, and in fact I think it did, by some third party crack, until google prevented it. But at the moment I have my silent PC plugged into the tv by HDMI and use a wireless keyboard which is buggy and annoying. What I want to be able to do is for my PC to transmit its output basically onto the screen of my nexus so my nexus essentially becomes a touch screen controller for the TV so I can load my media, browse but have it on the big screen, directly mirrored from the Nexus. Is this possible?
