I'd like to use my phone instead of a TV as a small display monitor (with a cable, not wifi). I have a couple of devices which have AV out on them, what I'd like to do is show their output on my phone (for example a MFT camera, so i can use it as a video monitor without having any special apps controlling it, or for a baby monitor that doesn't have wifi, it could plug in and i could see the feed on the phone and take screenshots perhaps)?
Is such a thing possible? I have found the right cable on amazon (male to male, micro usb to mini usb) but i don't know if it'll just work? I have a Sony Xperia Z3 (f that makes any difference).
