Hi. I just bought an adapter from to connect from the "bottom" 30-pin output (in this case) to a HDMI cable. Thing is, my TV (also a Samsung, btw) will not recognize the HDMI connection, which works perfectly with my laptop. So, I suppose I have missed something here, most likely something quite elementary. Any hints, please?

Did you also attach the power adapter ?
I had the same thing when Trying to connect via the 8.9 dock. You need external power for hdmi to work
External power? As in plugging into the 30-pin thing, which is already taken by the HDMI adapter? (Now I'm SURE I have missed something . . )
Ah - the power adapter! Well, I knew it had to be something elemental! That being said, I can't say this seems like an easy (nor elegant) way of doing things, but it works. At least.
Thanks to the both of you!
Yeah I had same experience with you,

With my p7500 the same experience I'm now using it in every presentation I made.
Would like some light shed on the matter, how am I supposed to connect the Power adapter while the 30 pin port is taken by the HDMI adapter?
Execuse my ignorance ;(

Found out how through eBay listing description.

Has anyone tried to get a TV out going on the G-Tablet without having purchased the dock? We have a standard and mini-usb available, maybe it can be done?
electroniccrap.com has a dock connector to hdmi cable.
You can also get a cable from electronic crap which plugs in the proprietary plug and outputs HDMI. Just got mine and works like a charm.

I've tried connecting mine through both USB ports and it's a no go. When I put my TV into USB mode, it says "no device connected" My Digital cameras and video camera work fine, but not the G-Tab.

Does audio work through this cable?
hdmi out
can you post a link or name that cable so we can find it on electronic crap? That would be great-
Nevermind- found it!....LinkIt $29
Since it works like a charm I'm assuming audio works. Do you need to change any type of settings on the g-tab for the video out to work? Or do you pretty much just plug it in and you're good to go?

I bought the HDMI MHL Adapter from Monoprice, great price and stuff, but it doesn't seem to work right. For one the power cord doesn't fit good in the HDMI MHL Adapter, it seems like it can't go in far enough to snap and hold so it falls out a lot. Also it took many tries of unplugging and plugging in the phone to get it to work with it. It also has frozen my phone quite a few times, especially if I have the HDMI MHL Adapter hooked up and someone tries to call me. I bought this phone because I wanted to be able to play my movies on friends TVs when I go over their house, but this just doesn't seem to work.
Does anyone else have experience with the Monoprice HDMI MHL Adapter?
I think I'm just gonna buy the one from Samsung.
Thanks for the heads up. Just started shopping around for one.

Make sure you report it to monoprice. They listen. It may take awhile though.
I voided my warranty and your mum.

Silly question: I bought a similar one from newegg, but I don't know how to get it to work. For example I'm watching a youtube video on the phone, how do I make it output to the TV? (Of course I had it connected to it through an HDMI cable).
I got mine in the mail last night and it works just fine.
The regular samsung usb cable connected without problems.
Make sure to connect the power on the adaptor before connecting it to the phone.

I bought the official HTC adaptor for this and I can't get it to work.
I plugged power into it, used a brand new HDMI cable and nothing works at all.
The first time I plugged it in, an icon came on up top saying HDMI out but nothing showed on the TV screen.
Now, when i plug it in the phone starts charging but nothing else happens at all.

There are a couple members with the MHL adapter. You might just have a faulty accessory because to my knowledge none of them have issues.
MHL adapters do not work on their own, you have to plug a micro USB cable into the side to power it.

Here's the one I'm using.

Probably find a cheaper one out there, but this one worked for me.
Just out of curiosity, what would be the purpose/need to hook HDMI up to your phone? (And no, I am not being snarky or a d*ck, just curious as to what it's used for...)

You can plug the phone into an HDTV and show pictures or play movies at their full resolution on the screen. This phone can probably play HD video better than my (aging) laptop can.

Not sure if you tried disconnecting all of the cables and reconnecting them, but I'd give that a shot if you haven't already. A battery pull may not hurt either. Could also be a bad adapter or phone. Saw a few similar issues in the accessories section.

Did you choose the output in whatever application you are playing the source from? In the standard sense player, for example, there is a button that says output right next to the beats logo. I have heard that the option "TV" appears there when you are connected via HDMI or wifi to a televison.
For me, as soon as I plug in the adapter to the phone an hdmi icon appears in the notification section and the display shows up on the tv.

Yea, mine did that the very first time I plugged it in but it hasn't done it since.
The adaptor has to be defective, I have read a good percentage of them do not work correctly.

I'm using the cheapest one Amazon sells and it works great. I remember seeing someone else had a defective phone. You may be in the same boat. I'd try another adapter and if that doesn't work I would return the phone(exchange)

This is somewhat counter-intuitive, but the Samsung MHL adapter works extremely well. Oddly enough it works better on the Rezound than it does on the Infuse or Epic Touch 4G.
All that to say, yeah, you probably have a bad adapter.
Here's an MHL adapter people posted about using successfully in the accessories forum:

I am also using the one from monoprice. It works like a champ no problems and is only $15. Highly recommend it!
Mine was getting the HDMI logo at the top but no output I was useing the USB OWM rezound wall plug that came with he phone. Well I used a better one i had here and now HDMI out works great... It just will not work with the HTC rezound wall plug power.. even works off of my PC's usb power just not the OEM one.
I've searched on the flyer forum quite extensively, and there's talk of HDMI cables and so on, but nothing about HDMI working on the latest HC OTA.
Has anyone tried this out yet? If so, has it worked for you?
In my experience (tried with two TV's) nothing is coming up on the TV.
Any help is much appreciated. Thanks.
Works fine on HC, as always the MHL box is required to interface and the box requires external USB power.

Could you tell me what Micro USB power adapter you use? I don't have any and need to buy one but I wasn't sure if there was a specific/minimal power output I should look for.

Doesn't seem to matter. I've used probably 6 or 7 different power adapters with no problem and also powered it from my PC usb port. As long as it supplies 5v @ at least 500 ma, the same as a standard USB , it should be fine. My favorite is a 4 port 2amp wall wart I got for $5 at a "5 Below" discount store.
So, is there any easy way to change the Tab 12.2 and keep USB as a data connection?
something like this?

The power point is used to power the connected devices and doesn't power/charge the tablet.
Plus it's only powerful enough to power USB devices, it will not power 2.5 " HDD's for example.

Did you order one of these? If not, I'm curious as to where your getting the specs from. I'm hoping your wrong of course, lol. My external 2.5" HDD runs perfectly with 500ma, so if I had my 2100ma USB wall wort powering this adapter, I would assume I would get 500ma (if the power is being limited) or more out of the 2 usb ports. Unless Samsung is planning on selling an overpriced breakout box, I don't understand why they would cripple such a nice tablet with this one port for everything crap.

I ordered the 1 port version, not the 2 ports version mentioned above.
It's true the tablet can power 2.5 HDD's when connected to any/most OTG cables, but I also wanted to use it with a phone (which needs the HDD to be connected to a power source).
After I sent the 1 port version back, I looked at buying the 2 port version, but after reading the small print, I found out the tablet couldn't be powered/charged, the power point was used to power the connected devices.
Two examples of the 2 ports version I looked at:
http://www.amazon.co.uk/Micro-Adapter-Cable-Galaxy-EXCITES/dp/B00J2QID16/ref=sr_1_29?ie=UTF8&qid=1402734708&sr=8-29&keywords=otg+cable

The USB Power Port only supplies extra power to the dual OTG ports. It will not charge your mobile phone or tablet.

The 2 port version, obviously will work when connecting 2 devices at once, but the power point, won't be any use, as the tablet will already be powering the devices.
That's my understanding of it.

It does not charge the tablet. It does supply power to the 2 usb ports even when disconnected from the tablet. It is an inexpensive alternative to the Samsung otg to usb adapter I purchased for $19.99.
Hopefully Samsung or some other company comes out with an adapter that can charge the tablet and has usb and hdmi ports.

I don't think an MHL adapter works with a regular USB port. Not 100% sure though. Just ordered a male USB to female micro USB to try, lol. Even if it doesn't work, that's one adapter I don't already own.

here u go guys...meant to post this almost a week ago when i saw the topic. i ordered one for my tab pro 8.4 lte (should work for every variant though) & it works great...u can use hdmi (takes the regular full sized cable) with a hard drive/flash drive or large sdcard connected simultaneously while charging your device but the charger doesnt even need to be plugged up for hdmi to work. The bonus for me was that i won mine in an auction & only paid $4 for it (normally around $10 as u can see from the link which still isnt bad)...if there is any negative about this thing its all the weight/stress resting on that lil micro usb connection which means it basically needs to be placed perfectly flat. They also have a dock version which should solve that issue for around $20 which i plan to order & test at some point...hope this helps other users out with your decision

And you're sure, that HDMI and USB-OTG and Tablet-Charging works at the same time? Thus, I'll be able to play a video from an external harddisk to my TV over HDMI out.
