Probably a bit of a stretch here but if anyone can help I'm sure it's the XDA community. For full disclosure I'm using a Galaxy Note 10.1 and cross posting this here because I know the GSIII Community is just bigger than the Note 10.1 and the AllShare device is identical.
I have the AllShare Cast Dongle and it works fantastic. Use it with HDMI connection regularly, also use an HDMI to VGA Adapater. I purchased an HDMI to composite adaptor but can't get that to work.

I've done some searching and have found people with AppleTV and have also used the adapter with my laptop, so I know it works. The problem though is that it seems the AllShare Cast Dongle doesn't turn on when it's plugged into this device.
I can get the tablet to connect momentarily but it always disconnects and the device turns off. Anyone used something with the AllShare Cast Dongle to convert the HDMI to composite? Could you share what it is?
Any suggestions on why this setup might not be working?

All of the Galaxy Tab products designed to use the 30-pin connector should work. The HDMI adapter I had from my P1000 worked just fine with my friend's P7510, my old P7300, and now my P6800.
So, yeah, it'll work.
I have one intended for the 8.9/10.1, it works with the 7.7 WiFi. The USB adapter also works.
Just chiming in that it works fine on the 7.7.
I find it kind of ridicolous that the hdmi adapter requires power to function. It makes sense if you would be watching a movie but if for example you are holding a presentation and you want to hold the tab in the hand this is a serious problem, because of the second cable and the fact that the charging cables aren't so long.
Has any of you guys have any idea if this is a hardware requirement or if this could be turned of via software?
If not how does the picture-quality of the hdmi-cable compare to the quality of a simple AV cable?

I'm not sure there is a simple AV cable solution for the 7.7 afaik... I don't know the exact post, but I remember seeing something a while ago about someone trying the AV adapter from the original P1000 with no luck. Also, to answer your question about picture quality, standard composite video only allows for about a 720x480 or 720x576 resolution (depending on region), which is pretty bad compared to the native 1280x800 of the 7.7. Also the 16:10 aspect ratio of the 7.7 is wildly different than the 3:2 and 5:4 (respectively) ratio's of the other two composite displays, so everything will look all funky and unreadable...
Now, having said all that, I do know that HDMI provides 5vdc power via pin 18 (17 is the gnd), albiet, not very MUCH power (50ma max), but perhaps it might be just enough that one could make a modified HDMI adapter that tricks the tablet into thinking that an external power source is connected... Might be a fun DIY project!
Just a thought
HDMI Adapter - Picture but no sound
Hi, first time poster here, I've searched all the forums and posts I could find and I don't see any answers relating to this specific question, so here goes.
I have just got the Galaxy Tab wifi version (P6810) and I bought the EPL-3PHPBEGSTA hdmi adapter to be able to connect watch videos on my TV screen.
This gives me perfect picture but no sound at all. I have power lead connected to the adapter.
I have tried playing through MXPlayer, You Tube and standard video player. None of these give me sound.
I can use the same HDMI cable, TV and connection route and connect my galaxy nexus via MDL to the TV and I get both picture and sound.
I am connecting to the TV via a Denon home theater AMP which was why I checked that the phone was able to send on the same settings & cables.
I've not seen any posts with this same issue of no sound at all, has anyone seen this before? Or does anyone have any idea on what I am missing?
Really two questions:
1. Is there a way to adjust resolution or over/underscan on the HDMI output of the tablet? When I have the tablet connected to my TV, there is about 1-2" of black border around the mirrored image.
2. I am trying to output to a LCD Monitor, mHDMI>HDMI adapter to HDMI>DVI cable connected to my Monitor, but the Monitor does display any image - not even a "out of display range" error. The monitor will briefly turn on, then dispaly "no signal." Both adapter and cable work independently of each other when attached to my TV. Is this a problem with the tablet, cable configuration, or my monitor?
Is there anything I can do to check/adjust the signal out from the Tablet? I am using the OG Samsung Dock w/HDMI out. Please let me know if I can provide any additional information.
[Edit] Currently running Tasks 14 Full Rom with Pershoot's latest kernel. And I have the WiFi only version.
same issue
I have a samsung galaxy 10.1 tab in the office and I am trying to do HDMI mirroring. I do not have a dock but I have HDTV Adapter. I do not have a HDMI monitor at office. So, I used a HDMI to DVI converter. When connected, nothing happens. no errors on the monitor just like you said.
So, does it require a TV/Monitor which has a HDMI input?
Or does it simply require a media dock?
[Edit] Does HDMI mirroring requires rooting?
Any help is appreciated.
Thanks
I would assume HDMI mirroring is built-in, as they sell addons for HDMI output. Semi glad to see someone else has the problem... but now its two of us with the same problem lol. Later this week I'm going to try an ICS build, see if there is any difference.

Well, I was glad I was not the only one with this problem
I did some Googling, search Android HDMI to VGA. Should turn up some links exposing the issue. Basically, android cannot natively do VGA. Need a HDMI to VGA converter, possibly powered, but there isn't much information. Dealextreme sells one for $38... and it may not work.
Sucks, seems like a decades old standard would be something engineers would think to maintain compatibility with.

give up
At this point of time, I am giving up and tell my boss to buy a new tablet. This is my office one.
I have Coby Kyros - bought it for cheapness. Will try rooting that.
mHDMI Connected to HDMI>DVI Cable = No Output on Monitor?
I have exactly the same problem with my XOOM and my Samsung T220 DVI-D monitor
I note that noboby has actually answered the questions posed by the previous posters.
Is that because no one knows??
The HDMI and the DVI-D signals are both fully digital and according to info I read on the web are pretty compatible.
I have aslo seen implied that a 5V signal which the DVI-D requires is maybe not available on the HDMI output.
How about some of you clever tech guys on the forums letting us less well gifted folks know if this is really a no-no and maybe why this is the case.
Thanks in advance for your help
Sorry folks have posted this in the wrong place ooops
Dear Fellow XDA-Developers,
I have spent the last 3 days researching all I can on the Galaxy Note 2, awaiting its final arrival on Verizon. I've seen great videos and posts on its external connectivity (props to NZtechfreak for his work).
I've also seen successful efforts to connect it to a HDMI television directly, no need for the docking station. Very cool. :victory:
What I've *not* been able to discover is whether anyone has successfully been able to hook a Galaxy Note 2 to an external touchscreen and have it both display the video output and serve as an input source for navigation?
Has anyone tried and succeeded here? Any tips or leads?

It really depends on how the input is connected. Most of the touch screens I have seen connect to the pc via generic mouse drivers. If that is the case, you would need the media dock to connect to the touchscreen via usb and hdmi. (The mhl adapter does have a usb port, but it only provides power).

Thanks SFBPro! Could you forego the media dock if you purchased an externally powered USB hub? Are there any options other than the media dock?
And to anyone else, any examples of specific hardware successfully working here? Many thanks!

How do you plan on getting the video on the screen using the hub? Are you thinking about plugging in a MHL into the hub? If so, I don't think that will work.
Did you find a solution? I want to Mount a external screen in my car and connect my Note 2.
Having a few problems with mirroring my Z2 tablet to a TV/projector. Just wondered if anyone could shed any light on some of the issues I am having as I seem to have reached a dead end.
I connect my xperia Z2 tablet to a none MHL projector using the Sony IM750 MHL adapter to present course slides at work and use it to connect to a none MHL TV at home. The picture is good but the adapter uses the power source and this drains the battery slowly from the tablet. I think the reason for this is that the IM750 is MHL 1.1. The tablet supports upto MHL 3.0 but as yet there does not seem to be any compatible adapters that are will work with the z2 tablet above MHL 1. If there was I am assuming that this would allow more current to get to the tablet and less or none at all would be drained from the tablet battery? Samsung currently sell an MHL 2.0 adapter but this will not work with the z2 tablet as it is has a 11 pin fitting rather than a 5 pin. I wish that someone out there would make a 5pin MHL 2.0 or even better MHL3.0 adapter that would work with the tablet, I have spent many hours on the internet but cannot find one.
I have also tried miracast to connect my tablet to my LG TV but there is noticeable lag and the screen can be glitchy at times. Does anyone know whether this would be the case if I used the netgear PTV3000? would it be better than the TV and is it worth a punt from amazon I suppose I could always return it if it does not work as well as I like.
Any ideas anyone it just doesn't seem at the moment that there is a reliable solution to connect the Z2 tablet to a projector or TV or has anyone found anything better?
If you don't need screen mirroring (do you need it? Really???), then other possibilities to bring video or photo to a screen are MUCH better / more problem-free and widely recommended than MHL or Miracast.
- Chromecast
- Android TV sticks / boxes which can receive content via DLNA
- Raspberry Pi with XBMC
- Other mini computer (like Intel NUC) with XBMC, Plex or something like that.
Stop bothering with MHL or Miracast, it will save your nerves.
Yes tell me about it it's a real pain. I have quite specific needs so I think I probably do need to mirror. I work as a trainer giving presentations all over the place so I need something that is not dependant on having a wifi signal as it tends to be poor at best at places that I work, so mhl and miracast do seem like my only options as they don't require connection to a router. As far as I am aware there doesn't seem to be a perfect option for none Samsung android tablets which is disappointing as I am big fan of my z2. I might have to go back to my win 8 laptop which I don't really want to do. I can't understand why there is not a 5 pin mhl 2.0 adapter.

I think the issue, is Chromecast requires the user to be part of a Wifi Network to connect?If you're in a location where there is no Wifi available, well........
Does anyone know what OTG HDMI adapter I need ot which one is correct?
I was order one before I was get the phone and now I see the plug was not compatible.
Sorry for bad english and hope you understand my question
The cable your looking for is called an mhl 3 cable but Samsung stopped supporting mhl starting with the s6 I believe. Casting is a much better option IMO anyway. The last mhl adapter I bought was for my note edge and it was around $60 for the Samsung branded version with back charge. You can pick up a chrome cast for half that and all newer smart tvs have native casting built in.
Ok thanks. But I think with chrome cast will be too much lag for playing games with phone and screen showed on tv?

With the new Chromecast and a decent router you should be good... I haven't really tried to play much but I showed off a few games that way.
thank you. I will buy chromecast and try this way. Hope my internet speed was fast enough with screen mirroring without lag.
If will my TV support screen mirroring I will try this way but its not.
What about if I try change the connector with right one? Plugin on adapter was not right, but attached was the right one.
Problem was only if Samsung was not support mhl cable anymore.
