Passive MHL cable verified working with N3
I received this from Amazon yesterday ...
This is a passive cable, different from the MHL->HDMI adapters that Samsung sells in that it has no electronics and as such requires connection to an MHL certified input such as those found on the latest TVs and receivers. It also has a 5 pin micro-usb 2.0 connector so requires the 11->5 pin adapter to be used with the N3.
The picture came up as soon as I plugged it in at 1080p/30Hz. The 30Hz limitation is from the Yamaha RX-A1030 I was testing with which supports 1080i/60 or 1080p/30 but not 1080p/60 through MHL. I'm also seeing around 300mA charging current with the screen on which means around 900mA total coming back from the MHL input on the receiver.
All of the videos I played went without a hitch (even those with Cinavia protection), with full 5.1 surround sound. In about 15mins of testing I drained about 3% from the battery so it's losing ground but slow enough that you could get through several long movies before needing to reconnect the N3 to a charger. The cable is a little stiffer and thicker than I'd like, comparable to high quality USB 3.0 cables but at ten feet long it's pretty reasonable given the bandwidth it's delivering (and the charging current).
