Below are photos of Netgear PTV3000 Miracast / WiDi receiver that is compatible with Android’s 4.2 Screen mirroring feature. It runs very smoothly using Samsung Galaxy Mega 6.3 rooted and Samsung Galaxy Note II non-rooted, however it does not work with Samsung Galaxy Tab 3 8″ with Android 4.2 — it shows some random green dots after confirming, that it is connected to Netgear. However sound worked just fine. Also, we are unable to run it with Galaxy S3 with android 4.1.2 custom ROM using All Share Cast. It connects, and then disconnects after a couple of seconds.
If you can get it to work with Galaxy Tab 3 8″, please leave a comment.
