[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.

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.

Is it possible to buy an MHL to HDMI cable? Where?

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

Inexpensive USB to HDMI adaptor

I am looking for an inexpensive USB to HDMI adaptor. There is a huge price range for this kind of device. I have found some online for as little as $12 or as much as $150.
Does anyone know if the inexpensive ones will will work on a Tab 10.1 with a USB dongle attached?

I never tried this, but I think chances are very low that any of them will work on android.
They need special driver software to use them as graphics devices. As far as I know, no such drivers exist on android.

So you're looking to bypass the oem product this way?
http://www.gottabemobile.com/2011/08/03/samsung-galaxy-tab-adapters/
Due to expense?

Struggling to understand why you would not use the HDMI connector that Samsung produces

I am looking for a lower cost solution. The Samsung adaptor is about $40. There are dozens of USB to HDMI devices out there for much less. If they will work when connected to the USB adapter that I already have, it seems like a reasonable way to go.

Fair enough, seems a little like a false economy to me as $40 isn't that much. I suppose it will depend on how much you use it.

You have to watch out a little with that ...
I assumed you were talking about 'real' USB to HDMI in your original post. As I mentioned above, these need specific driver software.
There are also a lot of MHL devices out there, which use a micro usb connector to get to the MHL signal. These can - e.g. - be used on some galaxy phones. These are not real USB devices. They use an USB connector to get to the MHL signal (which is close to HDMI) and translate that to HDMI.
Theoretically, these could be used with the Galaxy Tab 10.1 (which also has MHL output). But the normal USB connector for the Galaxy Tab will connect them to the wrong ports.

Moreover, price of the original adapter has dropped much.

Errr I got one HDMI adapter for my HTC Sensation, it worked out of the box, I dont think your statement is totally true..
Yes driver is included as far as I know anyway, why would samsung make a HDMI device that wasnt supported by Android..Or HTC for that matter..
Is'nt this down to the GPU rather than the Android.???
Correct me if Im wrong of course..But doesnt the Tab have a seperate GPU or Tegra Chip lets say..

Yes, that is correct.
The HTC Sensation also has MHL support. Yes, that is generated by the GPU. And yes, for that the USB connections are reused. So, the MHL output is send through the same lines as the USB lines. There is some nifty hardware in the HTC Sensation to make this work. The same mechanism is used in multiple devices. But it's not USB, so no drivers are needed for that. I guess that the main reason for this, is not having to add yet another port to these devices.
The Galaxy Tab 10.1 does not have a USB port. It has a wider port that brings out both USB and MHL (on different lines). So, the normal USB adapter will bring out the USB lines. Hence your HDMI adapter will not work with the normal USB adapter for the Galaxy Tab 10.1.
If you know how to reroute the lines, you might get it to work.
For more info, just look at MHL at Wikipedia. Just a little sniplet ...
MHL is connection agnostic (i.e., not tied to a specific type of hardware connector). The first implementations dual-purpose the most popular mobile connection (micro USB) and the most popular HDTV connection (HDMI). Other than the connectors being used, no USB nor HDMI technology is being used. It is exclusively MHL signalling through the connectors and over the cable. Other proprietary and custom connections are also allowed.

[Q] 11 Pin MHL + USB OTG

Hey folks, im crossposting this, as i believe it didnt get the attention it'd have had i posted this in the accessories forum in the first place

Hey there, i have tried gathering information about this subject and it seems all threads always lead to this announcement:
http://www.gottabemobile.com/2012/06/29/galaxy-s-iii-new-mhl-connector-also-enables-usb-on-go/
Short: Samsung have changed to an 11 Pin-out to enable USB OTG and MHL Hdmi out at the same time. I purchased an original HDTV Adapter (EPL-3FHUBEGSTD) which as far as i can reliably count indeed has about 11 connectors inside the USB connector that goes into the phone.
Now, i can get HDMI out just fine, but ONLY when i also connect the MHL adapter to a power source (a PC USB Port will do fine), however i have also read, that the phone is able to power the MHL adapter itself but obviously would not be charged then (no surprises there). This does not work however.
Further, connecting a USB OTG cable to the micro usb port on the MHL adapter does nothing. No notification and no devices connecting. No power either, since the LED on my USB Hub does not light up as it should. Connecting any devices to the hub does nothing to change that situation. If i leave out the MHL adapter and connect the USB OTG cable directly to the phone, everything works perfectly. I have tried this with 2 different OTG cables so they are not the problem.
This is an original genuine HDTV Adapter for our phones, which according to that post should be working fine with USB OTG.
AFAIK, this topic --does-- come up more frequently now as i can find a few more discussions about it, albeit none really helpful:

That wiki entry is the most interesting link as it definitely states that using MHL and USB OTG simultaneously is possible and is also the reason why the 5 pin layout was changed to an 11 Pin layout.
Looking forward to reading your replies!

I don't see why you would feel the need to ridicule me for bringing up this thread. it's not wishful thinking, seeing as even the wikipedia entry on MHL clearly states it should be possible. There is also a blog entry on the exact same topic and even the movement to boycott samsung accessories have stopped because of this: http://www.galaxymhl.com/
I don't really understand why people aren't looking into this more.

I'm not ridiculing you. I want the same thing. What I said was my legitimate wish list. I haven't bought the mhl adapter because I'm holding out for an all in one solution. I'm still waiting on Samsung to give us a product that does mhl and otg simultaneously.

I'm sorry, i must have gotten that wrong. I find it very confusing Samsung do no release enough information on this in order to make it work. Neither the phone documentation, nor the official 11-Pin HDTV Adapter manual mention this in any way.

I'm waiting also for a dock with MHL+USB OTG at the same time by Samsung, I dont understand why the official MHL adapter does not support this already but I've been searching and I have not found yet any example of both working together. It clearly seems that the MHL 11 pins cable we can buy right now does not support this since nobody has tested it succesfully but what I don't know is if that is related to Hardware or it also has something to do with software. I read a couple of weeks ago that Google was thinking about using the phone as a PC via docking, I think the idea comes from Motorola? So maybe the availability of both connections at the same time is also related with android, who knows, maybe in JB it will be possible...Has somebody tested MHL+USB OTG in JB with the official adapter?

It comes with the latest stock kernel and appearently won't boot with anything else so Samsung must have made some changes to it. In a few hours time I'll be back with information on how that worked out.

I can confirm it NOT working on Jelly Bean. The MHL adapter does provide video HDMI output, but only as long as it is plugged into an external power source. When connecting an OTG usb cable, there is no reaction at all. There has to be some way of getting the phone to power the HDMI adapter. Do any of you folks have a good link to a kernel dev who can have a look into this? There has to be a MHL modul for the USB driver. Ghokanmoral probably has more insight into this...
Summary: USB OTG and MHL work fine separately, but not simultanously on JB using a standard genuine Samsung EPL-3FHUBEGSTD adaptor.

The final result of this is that USB OTG work with the Samsung dock, but not otherwise...and that is why they changed the pins to 11. For the dock to allow for OTG at the same time as HDMI out. Does everyone agree?

I don't really know how this is accomplished with the dock, but if it works with the dock, I have to think that the same technique could be used to make it work with other adapters, too. If it's a matter of putting a voltage or a resistance across two pins, that would not be a big deal to do.

It was figured out in the thread that this was split off of.
we already found the resistor value to do it, the wiring.. everything.

Anyone try...
Anyone try a usb Y cable which will inject power over a USB and still allow for a separate device to be attached? I would post a link but i'm noob here. You can find it as "UTStarcom USB Adapter Y Cable"

The HDMI part of the split HAS to be powered...but the USB OTG does not. So...if there was such thing as an 11 pin micro usb Y splitter, then the OTG side would work while the powered MHL adapter was on. Essentially this is what the dock does.
Is it possible to create an 11 pin Y splitter? Someone needs to get one of those docks and tear it apart to see how the leads are split...lol

AFAIK the Slimport cable needs to be directly plugged into the USB port so it can switch the Nexus 4 from standard microUSB to Slimport broadcast mode on negotiating with the hardware. If you attempted to run the Slimport adaptor through a hub or Y-cable it wouldn't work.

Yeah, the microUSB port on the Slimport is for power only, the data pins aren't even wired up.

Suppose I connect Nexus 7 to a monitor through SlimPort. This monitor has USB ports built in. If I connect a keyboard or mouse to this USB port, will it work with the tablet?

No - this wont work.
As stated above the data pins on the slimport are not connected so the USB can't be used for anything other than power.
ie. Tablet can't do anything else over usb when the slimport is in use.
Bluetooth keyboard + mouse could work for you though

Thanks. My intention was to use the tablet as a PC alternative for my parents. I have dropped the idea. Now I am thinking about getting one of those Android mini PCs instead (thread here).

The issue is the limited number of pins on the Micro USB port are multi-purpose.
A Micro USB port has 5 pins, one is power and another is ground, that leaves 3 for data. These 3 "flip" (for want of a better word) between USB mode and Slimport mode, So it can only do one or the other at any time.
So the lack of data pins on the slimport pass-through port (as stated above) is not the issue. They didn't bother wiring them up because they share a couple of pins in common and so wouldn't work anyway.
[Edit]
Just to clarify a slimport Micro USB connector has 5 pins. Samsung on the other hand are now using MHL 3.0 and they are pushing on with an 11 pin connectors that open up all sorts of options such as simultaneous data connections and even multiple displays! nice!

Yeah i know what are you trying to do, but actually the only way to get wired audio/video signal is to use the slimport adaptor. (With wireless you would use Miracast but this isn't your case) So in your case you must use the slimport, the hdmi to composite adaptor and i think you should be good.

It would work fine with every device that support Slimport, newer devices do like LG G2, G Pad 8.3, Nexus 5 and so on. But you should check on the specifications of your devices. Before Slimport productors used to support MHL, which is almost the same but it keeps busy the USB port and on display that doesn't support MHL you should even buy an adapter which even needs external power supply.. if you can see on the Analogix Slimport adaptor you got a microUSB and the HDMI, the first is just for using it as the device one and HDMI for streaming. I was reading that Slimport has some limitations about the length of the HDMI cable, something like that it needs to be not longer than 50 centimeters otherwise you'd encounter problems..
Anyway i think that the Slimport adapter that costs just 15 bucks will be great.

Alright, looks like the SlimPort isn't going to work with the Samsung devices. Is there a cheap alternative so I can switch between Nexus 7 and the other devices? Specifically the S3 and S2 (Epic 4G Touch)
Thanks!

I think the only way is to use Wi-Fi Direct/DLNA. If you're gonna cast your screen just for viewing youtube, netflix and stuff like that, you could use the Chromecast, which does that particular job. It can't cast the entire screen but movies, audio (and other DLNA stuff) and compatible apps (you need to see on its webpage) can right now. To cast the entire screen you would need the Miracast technology but i don't know if there are any good dongles on the market that permit to do that as chromecast does. I hope you know what I mean, i'm not a native english speaker
You should take a look at the Chromecast if that can do what you need, or you can see Miracast dongles like this but i can't suggest anything

OK, I'm trying to do the same. I bought a slimport adapter and a HDMI to composite adapter. My N7 works just fine from slimport to HDMI to the TV, but doesn't work when I add the HDMI to composite adapter. However, if I hook my cable box through HDMI to the composite adapter, all works well. So its something from that slimport out of the tablet to the other adapter. What I'm trying to do is get the display mirrored in my van for the kids and the van only has composite inputs. I'm at a loss.
