hi all i got my self a mhl cable a few week ago and kept losing signal to my tv with it so i got a replacement and this one does the same... basicly i get the old style white noice screen at random when trying to use my phone and tv.. ps also their is alot of color banding with this mhl i have...
please please please help me, where can i buy one that will be problem free,
ps on a side note... can multiple bluetooth devices be connected at once.. ie i have a mini rii keyboard and the touch mouse is a pain to use so if i used that with normal bluetooth mouse would both function ok side by side?
I cant help you about the MHL adapter. Sorry.
Regarding Bluetooth devices. I use a BT keyboard, Microsoft BT mouse and a headset at the same time and it is working without any problems.
regarding your mhl cable
is your data (3G) turned on?
if its on then turn it off and try connecting your device to your lcd again
i had the same problem and i thought it was from the cable
but i read somewhere that if the data (3G) is on it will cause the disconnection because of the search for better signal and reconnecting to it
hope this helps you as it did for me
read something new about the 3G may affect the signal to TV. Mine also kinda weird - my MHL adaptor can output my Note screen to my home Panasonic 720p LCD TV and Samsung 27" 1920x1020 LCD monitor with no problem (but it looks much smoother on the 720p when zooming in and out) but it can't work with my in-law's Panasonic Full HD LCD TV. After connected, no signal at all.
yeah you really can see the color banding when its on a big screen. its there on the small display too, just harder to see.
did i hear right that with ics this will go away as they will switch to a high color depth always?
Thought I would ask the obvious question. Have you actually plugged in the phone charger to the side port of the MHL cable when using the MHL to output to the television.
Try connecting the charger to the MHL cable and then to TV and then to phone. Cause otg cable gives errors when done the other way around, so guessing MHL might give similar problems if you don't connect them in the proper sequence.
hiall thankyou so much for info.. ill try tonight..
@Teflanzy - ill try this 3g thing as i use wifi at home so this will not effect my usage
@bubblesmoney - yes mte it dont work at all without power cable, its required on the leads i have
as for colour banding im happy now i know its not just me and ics might solve this
hi all after much effort of testing i still get the signal loss even with 3g turned off is their any other solutions as the guy i got it from sent me a 3rd cable and all of them do the same
i had same issue.
solution is buy original, or very close to original samsung cable, i bought one and no more drops.

If it's visible on a TV then at least it's 100% certainly not a Note screen issue but purely a software problem.

Hii everybody. In a big problem here. I have a galaxy s2. I9100.
Got a MHL cable from ebay. Supposed to be official SAMSUNG adaptor.
http://www.ebay.in/itm/170773709311?...ht_2211wt_1139
And a high speed universal HDMI cable.
Now my problem is that when I connect this HDMI cable to the MHL and to the Charger and the mobile, it doesn't work the way it is supposed to be.
It connects fine to my TV(Toshiba HDTV) and mirrors the display, but only for few seconds. The screen on the TV goes completely blacked out, while the display on mobile is fine. Now I have to disconnect the MHL and connect again to the mobile to get the mirroring on the TV back. Again after few minutes the same happens. I can see the mobile charging via USB and even though the display drops on the TV, the TV is still in the HDMI mode(a black screen). Coz when I disconnect the MHL completely the screen on TV turns blue(indicating no input).
So this shud not be the case of loose connection.
Now can anybody help me diagnose the problem here.
Is it the MHL?
Is it the HDMI cable.(Although HDMI works perfectly with my laptop and TV)?
Is it the Charger? (Using samsung's box charger)
Is it the mobile, hardware or firmware? (on DDKL1 official release)
i have this problem like screen goes black out for a few sec at certain time on my toshiba regza. but its working fine on my phlilps tv. maybe you can try turning your cell into flight mode and see if it will help a certain? some said data may cause the interupt of it.

Thanks a lot dude. It worked.
But can't understand the relation between 3G and HDMI..
Anyways you made my day.
CHEERS.
I'm glad I read up on this before purchasing. I saw some fake Samsung versions, MIChn, I assume the OEM is MIKor? Please confirm if you bought the original.
I am also having problems with my MHL adaptor. I purchased one for £6.60 from eBay.
I contacted the seller as it was not working and they kindly sent me a second one, however that is also not working.
I have tried turning USB debugging on and off but it makes no difference. All that happens is it says USB connected and then almost immediately says USB disconnected.
I tried changing the order of how I plug the cable in to the power and HDMI and phone but still the same thing happens.
I previously had an HTC Desire HD so I am used to being able to select from options when a USB is connected!
Has anyone else managed to get one of the cheap MHL cables to work or will I have to purchase an official one?
Thanks for your help!
P.S. Hi, I'm new here!
mhl issue solved thanks for the solution

I have read plenty of people who have the same problem. When I plug in the phone to the tv via hdmi the phone freezes and resets. I have not found a solution for this. It seems like it is really hit and miss. Any help?
anyone? please?
I'm not sure if this helps but I had the same issue and switched to another HDMI port on my TV and it worked flawlessly.. I notice that the port i was trying to use shows up on the TV menu as HDMI/DVI for some reason even though it is clearly NOT a DVI port
Your cable is probably bad. Mine started to freeze up after working fine for two weeks. I checked the cable and the cord was coming apart at the top by the full hdmi connector.
Two new monoprice cables I got since have been flawless. The first was an amzer from ebay.
My friends, i bought the original samsung hdtv hdmi mhl adapter for my samsung S3 and please everyone that has one please verify if you have the same problem!!
When connected with the hdtv adapter it only works connect to the original charger, so far so good, the problem isif you notice while connect to this adapter the phone slowly keeps droping the battery level.... i think that means that the energy provided by the charger is inferior, not enough than the one that is being spent by the adapter...!!
When i use my adapter usually i have wi fi and bluetooth on because of mouse and keyboard..
Tryed with energy save mode on and off and made no difference...
HELP PLEASE!! THIS CAN BE A PROBLEM TO EVERYONE!!
How do i contact samsung for further help?
Thank You

Had any luck with this. I have the same problem
I want to hook up my Galaxy Nexus to an older HD Sony CRT set, but am having a problem. Hopefully someone here can point me in the right direction so I can go about fixing it.
I hook up my MHL cable to my Galaxy Nexus and plug an HDMI cable to the Sony CRT and the image appears, but then seems to flicker in and out between what I would expect to see and blackness.
The twist is that the picture seems pretty stable as long as I'm touching the screen (the situation is also better when PDK apps are running), so I'm cautiously optimistic this is a software issue concerning the GPU. If anyone has any more specific advice, I'm definitely open to hearing it.
Thanks.
Have you tried playing something else through the HDMI port of the TV? (a DVD player, a PC, etc.) The problem might be with the HDMI cable or the HDMI port itself and not the phone or MHL adapter
A settop box and game console work just fine through the same HDMI port and the same cable, so I'm pretty sure the problem is with the GN. Any ideas?
One bump for the weekend before I let this thread fade away. Hopefully a weekend reader will see this and know what's going on here.
Sounds like a faulty MHL adapter passing intermittent signal problems to the TV.

Yeah, the MHL adapter works great on several other sets, so I was assuming it something to do with the CRT.
Hi all.
I've searched for similar questions and can't find anything that gives me an answer... so here goes.
Model number: GT-N7100 (Samsung Galaxy Note 2)
Android version: 4.1.1
Modifications: None.
Problem:
- Connect MHL cable to phone.
- Connect power
- Connect HDMI to tv & MHL
- Phone pops up a message on screen advising that HDMI connection has been made.
- No output from phone to tv.
I tried originally with the wrong MHL cable designed for a Galaxy S2 (established this thanks to a post I found on here, thanks). Then replaced with one designed for the S3 which should (according to what i read) also work with the Note2.
Am I missing something here?
The cable used was from Amazon and is not a samsung original part. But before spending more money to get the samsung part i want to be sure i exhausted all options with the cheaper alternative.
Thanks in advance for any help anyone can give.

my theory is it has something to do with all share cast
I bought a 'generic' adapter at first, did not work. Ended up going with the Samsung adapter...worked fine...
make sure yr MHL cable/adaptor is compatible for note2/s3, they use different pins with older model
Hi all.
Thanks for the replies. [will do the whole thanks button thing in a minute].
I threw the adapter in a drawer for the weekend and pulled it back out this morning to have another crack at it.
Its the cheap n nasty adapter that is at fault. I shoved the connector into the bottom of the phone really hard this time, and instead of black, the tv screen went green. All green. A bit of jiggling later and i had phone output on the tv, but its a very sketchy connection and a slight knock loses the connection, even though the phone still thinks the cable is connected still.
Only problem then is that there is no audio coming through the tv. All phone settings suggest there should be.
So i went upstairs to try on another tv, and it works perfectly with video and audio (once the cable is rammed home good and hard).
Problem solved. For now, it will do. But I will at some point be investing in the genuine samsung part that should do the job properly. And a new TV for the living room ~ current one is old and was a budget model at the time, so you can imagine how bad it is by todays standards.
Hi, can you help to check if the camera apps work when you use mhl ?
Im using the sprint gn2 do I go with the same step when connecting mhl adapter? Before you connect to television is the phone suppose to be charging? I think I have to buy the right one .I bought mine amazon from china and still have not hooked it up to my tv yet. Can there be a problem with phone? Its new never dropped

i just got my samsung MHL adapter which is for the S3 but supposedly should work with note 2 also.
when i connect the hdmi cable and the power cable and then connect it to my phone i see a popup "hdmi cable cvonnected"
however,
my monitor (Dell 2408WFP) just goes into sleep mode.
i also tried another monitor.. same thing.
i'm on android revolution with perseus kernel... which is just a modded stockrom.
i have not made a samsung account so i don't have any of the samung specific apps activated... could this be the problem?
do you need to have that sharecast or whatever to be activated first in order to get the TV out functionality?
I bought Samsung MHL adapter last month for HTC One X and it works fine even without connect the phone to charging.
I just tried that to my new Note 2 and it doesn't work at all.. already try to charge the phone still not showing anything not even a notification saying my note2 connected to the hdmi...

ok.. i decided to actually create a samsung account and installing the all-share cast app hoping this would finally make the mhl work..
but alas..
same thing..
i connect power, mhl en and hdmi cable.... set monitor to look for hdmi signal...
phone then gives me the 'hdmi adapter connected' message and then the monitor goes into energy saving mode...
i guess my adapter is faulty.... it is supposedly a genuine brand new samsung adapter but i got it from ebay hongkong or china or whatever... so... well... you know..
i think i will order the wireless all-share hub in stead...

Try it using the 5V - 2A charger, i have read, somewhere i forgot, that 2A is a must for being able to use MHL.
I can't say if it is true or not, i'm atill waiting all stuff be delivered (All-share cast hub, MHL adapter, Smart Dock, etc).
Good luck

For me the MHL cable worked well with easy disconnections (any minimal movement). But I used it with the bloutooh mouse and so I didn't feel so much the issue.
Now the note 2 doesn't reveal the cable. I plug it in and nothing happens.
I don't remember if I changed ROM before the issue but it's sure I always had a custom ROM.
Can be a ROM problem?
I will try the MHL cable with my father's s3 and let you know if is a cable issue.
EDIT:
SORRY GUYS, IS A CAVE PROBLEM. ITS DEAD
I have rooted my device also. Come to think of it, this might just be the issue. Rooted with exynosabuse gonna try to unroot and see if it works. Still want it to work with root though because i use the sixaxis to play games..
Once u unrrot your note 2 did it work with the mhl cable

Just curious if anyone has gotten the keyboard and mouse working on a lapdock with the Note 2. The HDMI works perfectly, but the keyboard and mouse don't work. I don't know if it is possible, but it would be great if someone knows how to make this happen.
Here's a picture of my set up. Everything is connected so it *should* work. I'm thinking that it is a driver issue.
(The lapdock keyboard & mouse work great with Ubuntu 12.04, & Windows 7, & Raspberry Pi (Raspian), so I know that my connections are fine.)
Thanks!
Hmm, guess I'll be able to answer my own question after a bit of research. It seems that the Note 2 (like the S3) can't provide MHL & OTG at the same time.
Not sure if there is a way around this. I wonder if Samsung's SmartDock works, but I don't want to spend $100 to find out.
I'm increasingly interested in trying just this, smart dock + lapdock. Hard to imagine that it wouldn't work, but I wouldn't mind confirmation if anyone has tried it. The impressive low prices on lapdocks in the secondary market kinda offsets (and also kinda shames) the ridiculously overpriced smart dock.
I wonder if the lapdock's battery can provide as much power as the smart dock needs or if I'd have to have an external battery too.

the lap dock should provide 1 amp which is what the atrix needed and the chargers it came with. the s3 has a smart dock and it too only has 1 amp chargers...
plus I don't see the smart dock pulling more than 200mA it has to provide the s3 with at least 750 mA for the charge to survive mhl.
regardless amp drain in android devices is adaptive. even if the dock needs a full 800mA the phone will try to survive with the rest draining battery of course but working none the less just like trying to charge our 2A monster with a Bluetooth 150mA charger. it will try but at best slow down the discharge

I don't know if an MHL adapter will supply both HDMI and OTG at the same time but I know the phone is capable of it because this is how the Samsung Smart Doc works. 3 USB ports with HDMI out.

I've never gotten a green screen so I have no idea. And, you already did the basic troubleshooting. Are you using the Smartdock or something different? If you aren't using the Smartdock, maybe pick one up to see if it works. If it doesn't fix the problem, you can always return the Smartdock.

Based on what you are saying, it sounds like the issue is between your lapdock & MHL cable. Like I said in my previous post, I'd pick up a Samsung SmartDock and see if it works. Just make sure that yo buy from somewhere that you can easily return it in case it doesn't work.

Dear wilbr,
Thanks for the reply.
Do you use the original samsung MHL cable?...
I am using Chinese version of MHL.
HDMI troubleshooting guide says the below....
The green screen problem could be due to HDCP non compliance or syncing problem..

i had a similar problem, its was a shotty solder job on the "Budget adapter" (HDMI PINS). i took it apart and cleaned it, works perfectly now.
Plug your phone in, WAIT 5 SECONDS, Then lift up.....If you still have a problem, push F11 on the Lapdock... that manual cycles the resolution modes...at least thats what the manual says....
As far as the USB key board goes, im currently working a solution.... you have to power the MHL THROUGH THE DOCKS usb port using a donated USB cable with the end cut, solder it in directly on the board of the adapter itself, then make a micro usb extension that has the power wires cut and D- D+ reversed... I have a motorola ATRIX and im looking at the board, it looks like they have been reversed....ill post up some pics if i find this to be true.

Also, sorry to bring up and old post, but I have a reason to believe that the ZOOM bluetooth keyboard uses the same 30 pin connector thats inside the lapdock (connects everything together) all the connectors are the same, except on the ZOOM the other end is a BLUETOOTH module...this would solve the whole issue... im about to get one on ebay. Ill report back in a few days.
I WILL NOT LET THIS THING BEAT ME
