Samsung Original HDMI Adapter not working on first try

Well, I bought this using the 50% discount code that was floating around for weeks on this forum:
http://www.samsung.com/us/mobile/cell-phones-accessories/ETC-EIA2BEGSTA
I connected the HDMI cable to the TV and to the adapter, connected the OEM wall charger to the adapter and then the adapter to the Note 2. Nada. Nothing happened on my TV when I switched to the correct HDMI port (I have a Sony 3D TV so I thing it should support whatever that adapter requires).
I tried it without the 5 to 11 pin converter as I thought my phone uses an 5 pin USB (the tip looks like my charger).... Nothing. Then tried it with the adapter... Nothing...
On a previous tablet I had I had to enable "Display Out" in Settings. But I don't see any settings related to that under "Display" or "Accessories" on my phone.
Any ideers?

I suspect you have the wrong MHL adaptor.
The one you've linked to days it works with multiple smartphones, but as of the S3, Samsung changed the pin out of the MicroUSB port so existing MHL adaptors don't work with the S3 or the Note 2.
You need one that specifically says S3 or Note 2.

@foxmeister
in this kit there is 5 to 11 pin adapter that is required for s3 and note 2, so this adapter should work (with adapter and charger connected)

find a friend with S3 or another note2 to test it...

MHL issue on Galaxy S4

Hi,
I have a Samsung Galaxy S4 with original Android from Samsung. Today I bought this Samsung SyncMaster Series 7 / 750 screen, which comes with MHL cable and port. I connect the cable to my phone and the port behind the screen (which supports MHL), but NOTHING happens. Any idea ? I already have checked and I have the latest updates from Samsung when it applies to my android OS.

Did you plug the power micro usb into the MHL adapter?
If the adapter is generic or doesn't have a port to plug in a micro usb, it will not work.

[Q] Cable for OTG + charge on the Tab 3 8.0?

According to this thread:
I figured I would kick off some of the development for the 8.0 version of the Galaxy Tab 8. I've included the kernel I created recently which has helped with several performance issues and allows for OTG with Charging on our Tab 3 8.0.

How would one go about making (or buying if available) a cable to actually do this? I've done a lot of searching and can only find OTG cables with a 3rd USB plug that powers the slave device, not provide power to the host.
I'm researching the possibility of putting a Tab 3 8.0 into my dashboard as a dedicated car computer, and need to find a way to combine charging it with OTG to run a steering wheel button controller from it simultaneously.

[Q] TabPro 10.1 - USB changing

Would someone with a TabPro 10.1 please answer the following charging questions?
How long does this tablet take to fully charge from 25% or less charge?
If you attach a micoUSB OTG cable to a powered USB hub will the tablet still charge while using a device (USB harddrive, SDCard reader ... etc) that is also attached to the powered USB hub?
Can a microUSB OTG Y Cable concurrently charge from the standard USB charger and run an OTG USB device (e.g. SD card reader)?
I'm asking as I currently use a Nexus 10 attached to a powered hub with a USB ethernet adapter attached. Unfortunitely the Nexus 10 does not utilize the charge provided by the powered USB hub and looses charge. In this set up the powered hub only helps to power the Ethernet adapter so overall the Nexus 10 does not discharge due to the Ethernet adapter. I am hoping the TabPro 10.1 has a better charging implementation than the Nexus 10.
FYI: The Nexus 10 will not charge from its pogo connector when the micoUSB port is being used for charging or with an OTG device. The charging notification falsely indicates the device is charging.
Thanks for anyones insights.

I would like to know this too. I've purchased and the Note 10.1 2014 and this is the only issue I have with it is the lack of support for charging and USB OTG use. If the Tab Pro 10.1 or even 8.4 can charge with OTG I may exchange the Note. Thanks!

I just tried an OTG Y cable, it wont charge. I also tried a trick that worked on my lenovo windows 8 tablet where you turn the tablet off, turn it on with charger in, rip out the charger and plug in the OTG cable before it fully boots and then connect the charger to the OTG cable which allowed OTG+Power, didn't work on the tab.
IIRC this is something that can only be changed by a kernel modification as I think the old 2012 Nexus 7 could do this with a custom kernel, but I could never find a working download.
EDIT: Tried on my Tab Pro 8.4 running latest CM nightly

Can't Get Mirco to USB OTG to work

Hey Guys,
I recently bought a Micro to USB OTG cable but unfortunately can't get it to work on my new S Tab(10.5).
I am able to get it to work on my Galaxy S3 phone and old Nexus 7 tab so it appears that the cable works fine. My S Tab is not rooted and currently does have the latest updates. I also ran the OTG checker which verifies that my tablet has the necessary files. When I run the OTG troubleshooter tho it does not appear to be picking up my cable at all.
I originally bought this to use my wired 360 controller on my tablet, the 360 controller and flash memory sticks are the only things I have tested on the cable itself. Like I said above, my S3 and Nexus 7 picks up these 2 devices just fine through the cable.
Anything that I am missing? Any tips/quirks to get this to work?
Thanks so much for your time/help!
P.S. attempted to post link to my exact cable but couldn't because I am a new member.

Are you willing to have device root and flash a custom kernel?
If yes, then my SkyHigh kernel does support OTG and has in-built XPAD (XBOX) controller module and confirmed working by another user. Some games may require you to map the controller with a certain app, some without.
FS support is dependent on kernel. If you are trying to mount NTFS r/w, then you will need to also install Paragon app or navigate to /mnt/ntfs/.... for kernel NTFS r/o

It's possible that it could be your cable. I had problems a couple years ago with an otg cable not working on my Note 2 but working in a couple older devices. It turns out it was because the micro usb end that plugs into the phone was too short to plug in all the way. I'm not sure if it's a new standard or something, but my Note 2, Note 8, S5 and Tab S all seem to have a cable with a longer micro usb tip than any of my previous devices have.
Hold the otg cable next to the charge cable that came with your Tab S and see if the tip of the otg cable is a couple of millimetres shorter. Also plug the charge cable into the tab and notice the way it kind of "clicks" into place when you push it in the last little bit. Now plug in the otg cable and see if it has the same "click" feel. If not, then I'd bet it's your cable. I have an otg cable that specifically states that it's for an S5 and it works perfectly on all the devices mentioned above. I also have a generic otg cable that works on my old galaxy nexus but doesn't work on any of the above devices.
Here's the old thread in case that helps:

Thanks for the reply's.
I don't really want to go down the Root road because I have never gone through that process and don't feel comfortable with it at this time.
The cable Micro pin portion definitely doesn't fit as snug as the S Tab charger. The OTG cable actually appears to be longer than my S Tab charger Mirco pin. When plugged in you can tell it sticks out a smidge....The thing with that though, it does the same exact thing on my other 2 devices that work with the cable.
Guess it could be the cable, just hate to send this back and order another and be in the same boat.

Cable or no cable, if you wish XPAD controller, then you'll need the kernel or loadable kernel compiled module. Other features (some I described) also require kernel. ... all requiring root.
Since you've ruled that out, you just need to forget many features that are available with some other devices and move on.
Best of luck.
