iOS devices let you AirPlay the display to OS X or to an Apple TV. Android does similar thing with Miracast, but only the latest Android devices, and latest HDTVs support Miracast. Older devices were out of luck, till recent.
What you need to Mirror wireless display:
- Any post-2012 Android device (it might work on 2011 devices too, but not guaranteed)
- Any Rooted Android 1.6 – 4.4 ROM (stock or custom)
- Wireless router
Cyangonmod’s lead developer Koushik Dutta has made it possible to be able to wirelessly stream your Android display on to another PC, Mac, Linux, Apple TV, (and even another android device). This is an ideal thing to do when you wish to watch videos, photos, on the big display, without having to use any HDMI cable.
The best use case is of course gaming on the large HDTV, wirelessly. At present experience is far from perfect but its mostly smooth with frame-rates around 20fps for Full HD 1920×1080 resolutions. (720p phones might even achieve 30fps+, I haven’t tested it).
How to Wirelessly Mirror, Screencast Android Display to TV, PC, OS X
At the time of writing Mirror app is experimental, and available through beta signup. If you’re using CM11 nightlies, you should already have Mirror under Settings > Display > wireless displays.
Step 2. Once signed-up, go to Play store and install it.
Step 3. After installation, run the app, it will confirm installation to system partition, this needs root.
Step 4. Next time you launch app, you’ll have list of AirPlay devices nearby, and even record screencasts. Connect to any and start streaming screen.
Note: For viewing AirPlay stream on Windows, you can use any app that supports AirPlay rendering e.g. XBMC.
