Galaxy S III

A few weeks back we told you that the Galaxy S III would not be able to use the last-generation MHL to HDMI adapter cables because of hardware changes. Samsung has come forward with a much better solution than just telling you to buy a new cable, as they have built a 5-pin to 11-pin adapter that allows the old cable to work with the new phone. They also gave us a reason as to why the change was made -- newer accessories will need the 11-pin configuration. 

Samsung Galaxy S® III uses an 11-pin micro USB input, which allows it to support MHL output and USB on-the-go input simultaneously – an improvement over 5-pin capability. This means that customers can take advantage of new functions for accessories that are not supported by a 5-pin micro USB connector, allowing a deeper convergence between the Galaxy S III smartphone and a HDTV.

To ease this transition and to allow for greater innovation with Samsung accessories, Samsung Mobile will offer a 5-pin to 11-pin MHL Cable Adapter that will allow the original Samsung HDTV Smart Adapter to function properly with U.S. models of the Galaxy S III, as well as future Samsung premium smartphones. In addition, Samsung is offering consumers the ability to purchase the new adapter separately, or to bundle it with the original HDTV Smart Adapter. Our goal in offering these MHL adapter solutions is to provide consumers with the newest accessory technology while ensuring the highest level of device compatibility.

The adapter is available now for $9.99 direct from Samsung, and they tell us they will also be offering a bundle with an old cable and an adapter, which should be perfect if you have an older Galaxy phone or tablet and need the 5-pin cable, for $39.99. We're not seeing that one up for sale just yet, but you can hit the link below to see the adapter.

This addresses the one major complaint about the SIII (No USB connection while running an external display.)

Still not as functional as separate USB/HDMI ports, but much more livable.

Does this mean all of the current micro USB chargers I have won't work?

bdmridgback says:

No...the USB chargers still work, just not the MHL.

richardfoc says:

Okay, noob question here. I am moving from the DINC to the SIII and am wondering exactly which adapter I will need in order to connect to HDMI? Is it this one: Will I still need another Micro USB wall charger or will I be able to use the one that comes with the phone?

Many thanks in advance!

This seems pretty great! So we could conceivably see an Atrix-like laptop dock for the SGS3, or a desktop dock letting you plug your phone into your desktop keyboard, mouse, card reader, USB hard drive, and big monitor.

That's what I'm envisioning with a simple USB hub!


Way to come through Samsung!

just when I bought the new MHL cable 2 hours ago because I thought my current one wouldn't work

jfs101 says:

Is the USB in the international version different? The statement mentions the U.S. Galaxy S III instead of just saying Galaxy S III...

lembowski says:

So if you don't already have the Samsung MHL micro-USB to HDMI Adapter you need to purchase 2 items? Are they going to just make a new adapter that has the 11 pin instead of having to buy this 2nd piece?

Barton82 says:

"support MHL output and USB on-the-go input simultaneously" - And how exactly am I supposed to do that? I have an I9300 and genuine Samsung OTG and MHL adapters. I cannot see a way to use them simultaneously.

Any chance we could get some macro pictures of the 11-pin connector on the phone?
I'm curious how they've done that and still left it compatible with regular micro USB.

At first I thought this was the explanation we'd been looking for all along!

Then I realized that this creates as many questions as it answers.

A friend gave me a cable that he had spare. How do I know it is the right one? Cause he didn't gave it to me in a box or neither the manual....
