Unfortunately works with every slow charging the GPad.
Some adapters also apply 7.1 transmission to the receiver. While it is decoded DD and dts from players like XBMC or Mplayer, but there is no pass-through via SlimPort. So only downmix the receiver input (stereo).
Too bad that some manufacturers do promise too much.
All also have the problem that the charging connector will not go away on the same side as the HDMI port, so the charging cable is now increasingly unnecessary.
When KanaaN adapter strong buy recommendation. My test and price / value for money.
