Just an FYI

I had a Monoprice Mini Displayport to HDMI adapter, before Thunderbolt was a thing. Well, it wouldn't work with my 2011 MBA, it didn't transmit sound and it flickered on the screen.

So, I ordered the new "Thunderbolt to HDMI" adapter. It is identical to the Mini Displayport one. http://www.monoprice.com/products/p...=10428&cs_id=1042802&p_id=5311&seq=1&format=2

Anyways - I swapped out the adapters, and now the flickering is gone and the audio works great. I was told that the adapters shouldn't matter, but it appears that it is possible you need a new Thunderbolt compatible adapter for it to work in some cases.

Huge relief. I ran a 25 foot HDMI cable so I could plug in my MBA form my recliner. I thought it was the cable length, but it was just the adapter. Happy day.

Probably because it wasn't compliant with the interoperability guidelines.
