Samsung Galaxy S4 HDMI/MHL adapter

The Samsung Galaxy S4 is packed full of features, one of which has been present on earlier Samsung Galaxy models.  That feature is the ability to connect the phone to a larger HD display with a HDMI cable and special HDMI/MHL adapter.S4_HDMI_Adapter

Whilst there are complete wireless sharing options available the cable solution is generally more cost-effective and flexible.

The S4 will continue this useful function, but there is a new HDMI adapter for it.

Part code ET-H10FAUWEGWW (shown in the image) will allow you to do the above, but the benefit is that it supports the MHL 2.0 standard meaning there will no longer be the need to connect power to the adapter.

Whilst this is still to be confirmed the presence of a microUSB port on the adapter would suggest that this cable will be compatible with the Samsung Galaxy S3 and Note 2, albeit with a power cable connected. It could also mean that the port acts as a USB host, meaning that other accessories can be connected via the MHL adaptor.

  1. not having a separate power port is great; even though the Note2 has a beefy battery and could drive an external MHL adaptor, it’s disappointing it doesn’t.

  2. Hi Jon

    Thanks for the article, I find it surprising how few people seem aware or even interested in what their expensive phones can do! (Like Nokia users from 3 or 4 years ago that didn’t know they had navigation or USB OTG on board :-)

    Anyway, I’m wondering if you have any idea whether the 11-pin, MHL 2.0 enabled phones such as the Galaxy S4 can do the following:

    – stream video to an HDMI display that is NOT powered (such as a wearable heads-up display)
    – accept incoming video from a webcam
    – both of the above simultaneously, and without external power!

    I know that Samsung sells a dock that might do this, but it requires external power which invalidates it as a solution. Ideally the solution would use nothing more than a Y cable. I’m prepared to buy both a MHL-to-HDMI and MHL-to-USB cable and solder them together if necessary.

    What we’re trying to do here is use the Samsung Galaxy S4 Active as a “wearable computer”, playing content to the user on his heads-up display, while at the same time recording video from a webcam that he wears on his head or something. Kind of like Google Glass.

    I know this is a tough question but any idea from you would be welcome!

    Cheers,
    Boris

    • Hi Boris, slightly more technical than we normally get in our comments!
      Looks like I’m going to have to disappoint you and say the S4 adaptor wont perform either of these tasks that I’m aware of.

      The MHL 2.0 adapters will only work without their own power when connected to a compatible MHL 2.0 display (such as Samsung and other’s most recent HDTV ranges). The receiving HDMI port needs to also be MHL 2.0 wired to allow for the full duplex (2 way) communication and transfer of power back down to the adaptor.

      There’s no reason why you couldn’t have an MHL wired HDMI port to on HUD as you suggest – it’s effectively just a display like any other. Although I think it would probably need to be AC powered to meet the MHL specification and work with an adapter how you want it.

      I’m not 100% on that though. You could probably get around it using battery power and some clever hardware engineering but you then might be going outside the specification and risk making hardware that doesn’t properly conform to the standard.

      It might take some time to get a response but you could contact the MHL consortium at http://www.mhlconsortium.org/ for complete details of the standard.

      Regarding accepting video then the adapter wont do that either – it’s designed as a video out cable. All the phone software is also designed for video out, not to receive.

      I don’t think there’s anything in the actual microUSB port to stop video input (unless the Samsung hardware is specifically made to stop it). What it would probably require though is a custom adapter that allows for two way video and an app for the phone that is built to recognise video input. A lot more work!

      That’s about the extent of my knowledge and I’m stretching what I know. I recommend heading over to XDA developers and setting up a thread there. I don’t know how deep your technical knowledge goes, as some of the guys there can be very in depth, but you’ll likely get a much more comprehensive answer and suggestions on how to proceed

      • Hi Josh

        Thanks for the reply!

        I have contacted the MHL consortium, but didn’t get a clear or definitive answer. Seems like what I’m trying to do really is too far-fetched.

        I’ll head over to XDA developers and see what they have to say…

          Sounds like the best idea to me. As I said, sending the touch data back down the link is what you’re trying to do.
          It’s not really in the spec although the cabling may allow for it. All the best!!

  3. If I have a samsung S4, and an MHL compatible Asus 24inch monitor, can I output video to the monitor without the Samsung device specific hdmi adapter/ or powered adapter? The Asus 24 inch MHL enabled monitor came bundled with a micro-usb to Hdmi cable JUST for this type of application but I get no display when its connected. Thoughts?

    • Josh Bethell says:

      Hi Fallon, you will need the MHL adaptor for the S4.
      The micro USB port on the S4 is MHL ready, but requires the Samsung adapter to be connected to provide the functionality.
      The cable that came bundled with your monitor will be compatible with newer micro USB/MHL enabled devices with the MHL circuitry embedded into the micro USB port
