This app effortlessly lets you display photos from your phone or facebook account onto a big screen. Just navigate to http://screendrop.tv from your your browser on your big screen (e.g. PC or SmartTv) and follow the instructions given there and from the app itself.
When you start the app it will start a QR-scanner in which you should scan the code given to you at http://screendrop.tv. When that is done, the phone should have established a connection to your browser via our servers and will now be ready to send photos. Just navigate among your photos and click on the one you want to display, and it should appear on your big screen.
