MHL Cable or adapter

¿Where the fck can we buy an MHL adapter microusb-hdmi or a full cable to use with the phone?

tada!
http://www.clove.co.uk/samsung-galaxy-s-ii-i9100-mhl-adaptor

As clove give a mid june date, anyone know other site to buy a mhl cable now?

try here, but its more expensive
http://cgi.ebay.com/Samsung-Galaxy-...183007?pt=PDA_Accessories&hash=item5ae01ef99f
note: this was supposed to be sold for the galaxy s, but i think it didnt work, so it was abandoned. I think that what happenend. If im wrong, someone kindly correct me please

Hum, I think that MHL is a different kind of cable, in concept it is the same input output, but the middle conversor I dont know.
I prefer not to try at that price until I know for sure

Is this not all that is needed
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=320679284523
Hope so as i orderd one a few hours ago.

I doubt that'll work as it's not an MHL connector, which I understand is HDMI and USB combined, but if it somehow does... bargain!

Lol now i look properly its not going to work at all

imo very stupid not to use standard HDMI mini port... now we have to buy adapters and ****.. and the phone won't charge if you don't have special adapter.. epic fail imo.. anyway they should include adapters with the phone.

I agree, they should include the required cables and adapters in the box, other manufacturers like Nokia do with their flagship handsets.
I think MHL will ultimately be better than mini HDMI port though, since its looking very likely to become the next standard connection.
I'm hoping to get one of the MHL cable/adapters from the MHL consortium for my Clove Blog review, if I do then I will post up a youTube video for everyone. At the present time the consortium PR person is trying to procure one for me, but it seems likely its inordinately difficult, so remains to be seen whether I will have it in time for the review.

In the very least, you'd expect them to have manufactured and released the accessories by the time the actual phone is released.

due to my low post count i cant post this as a link.
have spotted this adaptor for the HTC Flyer, says will be in stock 16/5
I assume this would work guess a little more research needed 1st.

Here you go... It's supposedly the official Samsung Galaxy S II MHL adaptor.

First stock due mid-June just saying.

Can someone confirm for me that this is the same cable. They call it an Ethernet Micro-HDMI (Type D).
Edit: Monoprice[)0Tcom has them for like 5 bucks. I can give the link so you can see the cable once I get some more posts in here.
I'm not worried about the Ethernet part, it should not get in the way because the extra connections for it are female.
Also, there is a lot of great info on these forums. Look forward to sticking around and modding some phones in the future.
Edit 2: So when searching for the Samsung cable by Goog'ling the phone, they call it either "microUSB" or "HML port"
That site has two different types that they call: Mini-HDMI (Type C) and Micro-HDMI (Type D) the type C looks like the usual Samsung cable connection, I was just wondering if there is some different way they wired the Samsung cables so that we had to use those ones. I cannot see them doing that though since there are many devices switching to the same cable as well.

The trick is that standard HDMI so far does not include a link for power. The Samsung MHL adapter has a microUSB plug that connects into the phone and a microUSB jack to connect your charger, and the mini-HDMI jack to hook up to the TV so the device gets charged while playing back. In a future specification update, HDMI will probably be amended to include a power link.
Some info here: http://www.youtube.com/watch?v=ZtwTcnR0hqA

Clove told me that the MHL cables from different manufacturers will be compatible which is useful to know. I guess they all conform to the standard

" Also if your television supports MHL enabled HDMI connections, then you can charge your HTC Sensation when connected and control the Sensation using the television remote (MHL enabled televisions expected late 2011)"

Thats only true if you TV is MHL capable (hint: nobodies is yet).

i dont understand how the phone has is out but the cables are not? how do they know it works if theres no cables lol

[Q] HDMI cable

Anyone know where one can be brought? also why have I read stuff about the s2 having mini usb? it doesn't it has the same propriety connector as the galaxy s.

It's MHL. It's the supposed new 'standard' for connectivity. I think most devices are using that connection nowadays. Last I heard was Clove saying the MHL adapters won't be out until June.

really? so the original galaxy s had mhl as well? Any suggestions on what to do with my fancy new phone? so far apart from being super quick it just seems like a sleaker bigger galaxy s, I cant think of anything my galaxy s couldn't do :S
Oh I know I'm gonna see if the wii mote works on this thing

I can't find any evidence that it did.
http://en.wikipedia.org/wiki/Mobile_High-definition_Link
It's the new standard, but that doesn't mean older devices support it. The SGS2 is one of the first AFAIK

But nothing on the market will currently work? HDMI out from a mobile is just supercool!

I have both an sgs1 and sgs 2, my charger fits the micro usb (the only i/o connector) on the phones, perfectly

The connectors should be the same on the S1 and S2, but only the S2 is MHL compatible.
I think MHL can use any 5 pin connector to send an HDMI signal while receiving power for charging.
I'm not sure if you'll be able to use the MHL HDMI out and USB at the same time, but I hope this is possible.
I'm also guessing that the adaptor will need to be a clever one with circuitry rather than a passive adaptor. Does anyone know if this will definitely be the case, and if so I'd imagine it'll have cost implications! Hope I'm wrong and a passive adaptor is possible

Coming from a LG Optimus 2x, that came with a Micro USB ---> HDMI cable. These are available from Ebay for a GBP 10 - would these work?

Yea guessing its just MHL compatible as the old port was usb compatible. Thats annoying, with all the talk of this new standard usb-hdmi port I was assuming it would use a standard connector and not a proprietary one.
It stupid really if all manufacturers used the same connector we wouldn't have to have multiple chargers/docks/cables

You can't use the USB port for MHL and USB functions at the same time, this is confirmed (if you search for MHL at youTube there is a great video with a person from the MHL consortium explaining it).
To badasschris: this isn't a proprietary port. Samsung, Nokia, Sony, HTC, Toshiba, and quite a few other partners are involved with it, it seems likely to become the standard for mobile devices (iPhone aside, I am sure Apply will continue to push their proprietary ports).

Are you absolutely sure it isnt proprietary? Why I am getting confused is because it has the same port as the galaxy s1 and I heard nothing about that being a standard port and you always have to buy a samsung charger not a [standard port] charger e.g. mini usb charger for any devices which have mini usb. So you are saying at some point the other manufactorers will have the same port and I will be able to use my galaxy s charger to charge them?

Galaxy S is a standard micro USB port, and lacks the MHL connection, its not proprietary at all, I use several non-Samsung cables to charge the phone in my car and from PCs. Most manufacturers, Apple excluded, use micro USB charging now.
The port in the Galaxy SII is not the same as the Galaxy S, as it has MHL connectivity in addition, but its function as a micro USB port for mass memory and charging is perfectly standard, and doesn't require special cables or connectors of any kind.

lol I had to thank you there I've been a right plonker. I remember seeing someone say the origional galaxy s was micro usb and then when I saw it I thought that't not micro usb. It just clicked I have been getting micro and mini usb confused. When anyone said micro I immediately assumed mini
Glad I got that sorted.

That sucks. I was hoping to look into making a tablet dock that used a USB capacitive touch screen & HDMI output for the screen.
A laptop dock using Bluetooth for the keyboard and HDMI for the screen would still be possible, or a tablet that used Bluetooth for the touch-screen.
This phone is powerful - it's annoying not to be able to use the hardware for more than just a phone.
I reckon Motorola is thinking along the right lines with the Atrix, and I hoped other manufacturers would be too, but this combined port indicates Samsung are probably not.

Plus you have the added fact that samsung like to mess with bluetooth meaning many devices wont work with it. I really hope the bluetooth situation gets fixed somehow as this device paired with a screen and a bluetooth keyboard/mouse and game pad gives you a portable computer / games console. without it its just an amazing phone

This should work perfectly with bluetooth mouse and keyboard, my SGSI does. It should also work with a Zeemote, unfortunately it doesn't have enough buttons to be that good for using in emulators.

I can confirm that the igo stowaway bluetooth keyboard works fine w/the SGS2 in case anyone's curious

Galaxy S III MHL Adapter Supports USB OTG--Work with GN?

The new MHL adapter for the Galaxy S III supports both HDMI and USB OTG simultaneously, according to this article:
http://www.gottabemobile.com/2012/06/29/galaxy-s-iii-new-mhl-connector-also-enables-usb-on-go/
I'm wondering if this means it could be used for USB OTG with a flash drive while charging the phone at the same time--something that's impossible with current adapters and cables. And does it also work with the Galaxy Nexus? Does anyone happen to have the adapter and a GN to test this?

My friend has an S3 and I know the 5 pin MHL adapter we use doesn't work with his because of the pin configuration, so I would assume if he can't get HDMI out using the 5pin, we won't be able to get HDMI out using the 11pin. Of course I am only guessing, but it makes sense to my mind.

I don't see how it could work, to use the HDMI out you need the charger cable plugged in to the MHL adaptor. So where would the OTG cable go?

Looks to me like the standard S3 MHL adapter has a micro USB "charging port". Could be that it could also accept an external drive. I don't have the phone or the cable yet, so I can't test. Maybe somebody who has both could post results?

it's not actually a charging port, it's a power port because apparently it needs more power to output HDMI, i.e. if you don't have the charger plugged in to the vacant port, no HDMI.

Samsung does sell a bunch of dual head micro usb to usb cables.... so maybe you need one of those and they sell this: http://www.samsung.com/us/mobile/cell-phones-accessories/ET-R205UBEGSTA which says it allows you connect drives, keyboards, etc to S3's....

Yeah those work, I actually use this one:
http://www.ebay.com/itm/Micro-USB-2...100-Note-i9220-Nexus-i9250-XOOM-/120894431890
or something similar, but you still can't use HDMI when you use those
you can however plug in keyboard, mouse, usb drive and anything else you want all at once which is cool

only MHL is affected by the pins, usb OTG is not affected by the new layout

OTG+MHL? Maybe (anyone taken an MHL adapter (or 11pin to 5pin converter) apart yet?)

so, anyone taken apart an MHL adapter yet?
i have a sneaking suspicion, that the move to an 11 pin is what will allow BOTH OTG, and MHL at the same time, but i could be wrong.
look inside your USB port on the bottom of the S3...
whatya see?
the normal 5 pins on the USB part.. but what is that in back wall? THE OTHER 6 PINS!
yep, that is why you cannot plug the MHL adapter into a hub or anything.. there is 6 pins are missing.
Now, i am wondering:
has anyone taken it apart to see if the 6 pins are used alone, or if it uses the the USB also?
if it uses only the 6 pins for MHL-ness, then it should more than possible to make an OTG/MHL adapter/dock.
more thought says, if my theory is right, an 11 pin to 5 pin conveter may be the key.. and an otg can be spliced in to give 2 outputs: MHL in one (using an s2 MHL adapter) and OTG in the other.....
anyone wanna tear their adapter up? or are you guys gonna make me spend some money?

I ran across this post looking to see if anyone has done this yet. I am going to try to grab the 5 to 11 tomorrow and tear it apart (since it's the cheaper adapter). My plan was to rip it apart and if the original 5 pins are available, splice just as you mentioned.
I can't find a decent picture of the microUSB plug to see if all pins are there.
Also I found this:
http://homixtech.en.alibaba.com/pro...Galaxy_S3_11pin_To_Micro_USB_5pin_Gender.html
Which makes me think 11 pin microUSB plugs that work are available out there somewhere.

So, did you do this experiment? Has anybody found a way to get access to all of the pins and make OTG work with MHL?

I've been waiting for two months for an answer about this. I'm glad someone started a thread. I kind of have this hesitation to start new threads.
I would love it if this could be integrated with the seidio active dock.

meh, I think that is wrong. many people have done exactly what it says you can do, and it doesn't work.

Makes me wonder if the boys at Samsung made a press mistake. If indeed you can't use both with the correct cable, then why make a port with 11 pins? Seems a waste of resources to me.

I have never seen anything from samsung saying that MHL and OTG was possible.. just speculation in websites.

It better be possible because if not all Samsung's managed to do is make us buy hugely overpriced new MHL cables when they could have kept the old type, but I guess Samsung's made some decent money giving people no option but to buy £30 MHL cables.

I hope Monoprice really is working on a cable. 35-40 USD is more than I want to pay, especially if I get a couple and/or an HDMI dock.

that would be key. I have sent out messages to people that may know, or may be able to find out, but i have not had success.
heck, If it can be done in the terminal (turning on items) i can make a shortcut that would do it.. but i have had no success with that either.

It's not possible I think.
You can use an MHL enabled tv wich powers MHL, (so you don't need the adapter) but how do you want to split that?
You can split the cables from the samsung adapter, so you have the MHL ones(6) and the usb ones(5).
But what then?
You need to connect the MHL ones to an hdmi cable, and connect it with an MHL enabled tv. And the usb ones to an usb port for OTG.
But will that even work with this S3?, because it is designed to get power from your charger via the extra usb port on the adapter.
Maybe it only works with the adapter, and not even with an MHl enabled tv...
I think somebody needs to connect the S3 to an MHL enabled tv, if that works you can modify the adapter and use the usb as OTG.

I found (and shared) the MHL value, and we already know the OTG value.. but it only seems logical there is ANOTHER value to activate both at the same time. we are postulating, the the reasoning behind the 11 pin, is to allow both. If adding just an OTG cable turned on MHL too, it would cause issues without an MHL connection. and the same with MHL activating OTG, without an OTG device connected. like i said, this is postulation at the moment, but there SHOULD be a thrid value to enable both at the same time. that value would be used by a future peice of hardware that does a whole "PC MODE".
and if it does not exist, it CAN be done, we just need more "stuff" a way to enable a special switch if you will.
some people are saying you can connect straight to an MHL enabled TV, but that has not been done yet (and since there are no 11 pin MHL cables, that are not adapters, it seem unlikell that anyone will until said cable exists. the S3 cannot send MHL signal over the usb part, it has to be either the extra 6 pins, or with the 11 to 5 pin adapter.)
essentially, the pins are there, and with some special software, or a hidden resistor value as to yet, unfound, and some custom hardware (as of now NOTHING 11 pin, has 11 pins in it) it SHOULD be possible.
but there is nothing that has been found (hardware wise) that is even modifyable to work.... yet.

What I don't understand, why does MHL only work with the power connected?
They could easily make an MHL cable with the 11 pin, and hdmi. That should work for only MHL.
Only no go I can think is that MHL drains your battery because of always having your screen on, and the MHL output.
So they decided to use the adapter with power, otherwise you can't use MHL feature very long before your battery is empty
I think inside the adapter they only use the pins for giving power, and not the full 5 pin support for OTG, and therefore OTG doesn't work when you want to connect something.
Inside the ROM they have maybe build in something that MHL will only work when power is connected.
Maybe the solution is very simple,modify the adapter so full 5 pins are connected.

diy smart dock for galaxy s3

after searching a little bit about 11 pin port in galaxy s3 and take apart an 11pin to 5 pin adapter i am thinking about make DIY smart dock for galaxy s3
i ordered mhl adapter and waiting for it mean while i tried to connect usb otg and extra micro usb connector together so i can use otg and charge the phone at the same time. but the problem is when i short ground and seance pin for otg ; charging doesn't work.
so any suggestion about the project?
i attached a plan of my project here
edited:after failing my 1st attempt i succeeded to make it work on my 2nd try!
this time i opened a 11 pin to 5 pin adapter. it has a small resistor which is connected ground to sense pin for hdmi out put. i removed that resistor and i connected 5 extra wire in the adapter 1. vcc 2. data+ 3. data - 4. sense 5. ground ( i showed in picture) . then i connected sense and ground with a 40.2k resistor.
then the 4 wire, which i i connected in 11 to 5 pin adapter (vcc, data+,data-, and ground) , goes to a femele usb where you will connect usb devices or usb hub.
and thats it!! hope you can try it too. if if have any other question just ask me

AW: diy smardock for galaxy s3
You forgot the vcc at the otg side, but anyway it can't work.
While charging you send 5v through the micro usb to the phone.
But in otg mode the phone will send 5v to the usb connector to supply power for the connected device.
I think your only chance is to use the inductive connectors to charge your phone while in otg mode.

I have a suspicion that the IC to the left of the Realtek one is the brains of the board. The RT chip does the hdmi out conversion and the other two longer IC's are usb host and usb audio. Can't make out the printed data on the unknown chip, but my best bet is if we can get a dump of whats on there then we might have a good chance of DIY hdmi/otg capabilities. i'm no expert by far, but just throwing ideas out there.

otg + charging success
hi guys! just want to give an update of my work.
i got otg and charging work together.
as in this post http://forum.xda-developers.com/showthread.php?t=1953061 i just connect ground and sense pin with a 40.2 k ohm resistor.
i ordered 40.2 k ohm resistor which i just got tonight. the hdmi adapter i have is a cheap and old one. its not mirroring the screen. i ordered a new Rocketfish MHL HDTV Adapter . hope that will work!! waiting for that to arrive!!!!
here i am giving 2 screen shot

mess lol
and here what i did so far....
i didnt connect micro usb female port for data sync because those i didnt get yet.
if anyone have any suggestion please tell me.
hoping to make it work.....

Great work, necomer. I've also been trying that for two months now, but haven't been able to make it work. I have the 40,2 KOhm resistor between sense and GND, and am able to launch smart dock mode on some ROMs I have tried. So, which ROM are you running? My only idea here is that maybe you having a US S3 is what does the difference (well, I'm assuming that, maybe you have an international one).
Thanks in advance, and once again, great work :good:

Hi. Thanks for reviewing I am using us galaxy s3 and just the stock touch wiz rom android 4.1.1.
And I received my mhl adapter. But when I am connecting it the tv screen going all black. Any suggestion about that?

I'm pretty sure your buying the wrong MHL adapter. The Note II and the s3 have a different micro usb than any other phone and require the samsung
MHL adapter.

Not sure what you are trying to do?
Amazon sells a combo cable so you can use OTG and charge the device at the same time. I use it to connect a 1TB portable drive to my S3 and Tab 2 10.1.
I bought the official Samsung HDMI adapters for both devices. They are powered and stream over HDMI to my TV just fine. Works with just about everything I've tried although some services require some workarounds. Copy protection crap.
What you are trying to do sounds risky. You might fry the phone.
I apologize if I haven't grasped your intentions but I'm kind of slow.
Edit: I think I may get it now. Are you trying to power, feed external data through OTG and then stream out to an HDMI display?
Dumb question as I said I'm slow but, how about the official Samsung HDMI adapter and use the power in port with a powered OTG combo cable?

what i am trying to do is, use otg , charge the phone and use hdmi at the same time. i thought it would be easy bcz samsung made new 11 pin connector in Galaxy s3 . so apparently its supposed to work ,as they are not using same pin for transferring data. But i dont have any idea about internal proses. while charging and otg at the same time is possible, dont you think we can connect hdmi with it in any way?
well all this is just guessing from my little knowledge. i want some suggestion from those who worked on this and correct my mistakes

Maybe... it's a HDCP problem...
If your TV don't support HDCP function(or authentication failed), then MHL chipset will show a black screen
(HDCP : High-definition Digital Content Protection)

I was going to this topic, being all hopeful that I finally might get my S3 in OTG+Charge mode. And then it turned out it only worked on a phone still running 4.1.1. I have 4.1.2, and OTG+charge did work for me before, but it seems Samsung broke it in 4.1.2. It is probably the fault of the kernel that came with the XXELLC (a stock 4.1.2 ROM) update, but how to fix it is beyond me.

Are you serious! I won't update mine then. I need to use that together! !!
Thanks for the information
