[Nexus 4 Accessories] texasice:
I got mine today (Actiontec ScreenBeem SBWD100A v1.0.21). It does not work out of the box. (for me anyway)

Logcat is saying something about hdcp failing. apparently qseecom is looking in the wrong directory so i copied the discretix files from /vendor/firmware/discretix to /system/etc/firmware/ but it still wouldnt connect. Interestingly i can connect to it as a wifi-direct device it then disconnects saying the app wasnt found (on the tv). so after that i tried reconnecting the wfd, it connects but looks like hdcp still has issues and actually locks up the device every time. Anyway thats my story.

log snipped
