[Q] micro USB to HDMI/MHL Adapter not working ! - Galaxy S III Q&A, Help & Troubleshooting

All,
Just bought a adapter cable (Micro-USB to HDMI/MHL adapter) from Ebay that is compatible with the Samsung galaxy S3. It states you can watch pictures or video from the phone to your TV in HD.
However, it simply doesn't work, is there something I need to setup on my phone (like the old TV Out) ???
Thanks for any advice received.

You probably got yourself one of the many fakes that claim to be S3 compatible but really just the old type MHL cable.

No you shouldn't have to do anything. Seems to be a bit of confusion among retailers though as to which cable is for s3. Is it generic? Do you have a product no.?

If it's compatible with s2 it's not compatible with s3. Seller has either advertised incorrectly on purpose or by mistake. Best contact them to seek a refund then you will see which it is.

Thanks mate, I was thinking the same thing but great to get feedback, guess I need to return it.

Yup, I can also confirm. There was an article on Engadget about Samsung rearranging the pin arrangement of the port.

Wow, that's not fair. It is Samsung that is selling fake MHL accessories.
That vendor was selling a real MHL accessory, compatible with the > 100 real MHL devices already in market. Sammie gave no warning or explanation, and advertised that the SGS3 supported MHL, so many vendors had no way to know that their MHL cables wouldn't work with the SGS3.
Now those vendors have to give people money back and take a loss, when all they were doing is selling authentic MHL stuff.

Sorry but I am being fair because I've seen dozens of cables claiming to be S3 compatible and some that say they made specifically for the S3 alone, I mean I just got caught out by one because 11 days after getting dispatch confirmation I emailed the seller and they said they just found out it isn't compatible and offered a refund, so it looks like they knew it was fake from the beginning and didn't send it but still charged me and confirmed it was sent, and I think everyone can agree this item is definitely trying to claim to work on S3 http://www.amazon.co.uk/Adapter-GT-...7TNA/ref=sr_1_2?ie=UTF8&qid=1341253133&sr=8-2

MHL is a closed-documentation commercial proposed specification.
With drafts, changes are rather the norm than the exception. There were reports of the old pin-layout causing issues being the reason for the switching of pins.
But anyway, Samsung is one of the main developer in the consortium so they can change specifications.
Noone said MHL had to be backwards-compatible between revisions.
It's the seller's fault for ASSUMING that there would be no changes and marking the cable as compatible without even attempting to try.
Additionally they could've been notified of this change several months prior release of the S3 if they had bought access to the MHL specification which is restricted but still available and most surely includes iformations about the reason and details of the included changes.
