MHL to HD CRT Problem - Samsung Galaxy Nexus

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.

Does your phone + MHL work fine when plugged into a different TV?

Yeah, the MHL adapter works great on several other sets, so I was assuming it something to do with the CRT.

MHL Adapter for Nitro HD

Now for all you Nitro HD users who didn't know that it is possible to stream video through the Micro USB port, well yes you can That port is actually a MHL port (Mobile High-def Link), which combines both Micro USB and HDMI features together, and all you need is a MHL adapter to connect your phone to your HDTV and stream movies while having your phone charged.
Now my question goes to those who know about these things. Any idea which MHL adapter is compatible with this phone, or can we use any adapter from any maker? And also, has anybody tried using the MHL capability on this phone?
Well, one would think it wouldn't be proprietary based on the fact that all MHL enabled phones use this as a standard now. I have used a MHL cable from an HTC Raider on a Galaxy S II and it worked just fine.
Does anyone else hear a slight grinding/grainy noise when you plug in the Micro USB? It always makes me feel like I'm breaking it.
any mhl adapter should work.
i use the mhl adapter from samsung infuse and it works! but remember to plug in power for it to works.

plug in power? what do you mean? I thought the whole idea behind mhl is that your phone will get charged via hdmi while streaming through it.

I think if the tv supports mhl mode then you don't need to plug in power.
If tv just has hdmi port then you need to plug in power.
The mhl adapter has microusb port for power input.

Which one and where?
Mine should be arriving on Thursday - just grabbed one of the many off amazon...
So my bro got me an Accell MHL adapter for Christmas and I'm finding it doesn't work with my phone. It doesn't even provide a charge. I'm thinking its physical dimensions are such that the connector into the phone doesn't go in far enough (kinda LG's fault for making the port recessed, kinda their fault for making the connector so damn fat). So, if you guys find one that works for cheap, do you think you could hit us with a link?
TL/DR, Accell's doesn't work, please post ones that do

it needs power for mhl to works. did you try to reboot the phone after you plug in mhl and power input for mhl? i tried on samsung infuse mhl adapter and it works!
Yeah, I provided power and performed every possible sequence of hooking it all up that I could think of and also rebooted several times. I really think it's the form factor of the Accell connector combined with our slightly recessed port that causes it to not go in far enough. I just need someone to give me a suggestion of a brand to buy that they know firsthand works well with our P930.

MHL MicroUSB to HDMI Adapter **VIDEO INSIDE

I bought the Samsung MHL adapter through Amazon - Samsung MHL Adapter and I must say this has been of the best inexpensive purchases you buy for your Galaxy Nexus. I decided to make a quick video to show you how great it works, please enjoy!

The MHL adapter is using full hdmi cable or mini hdmi ?
thanks for the heads up. I may have to get one of these.

Thanks for the video, it is really cool.
When I had my G2x with micro HDMI out, I bought all kines of cables to plug it into the TV from the comfort of my bed, and I really only used once or twice.
Maybe in the future I'll buy it but I think it will end up in my cable's cabinet.

How does this play out with USB host mode in Android?
Do I need another adapter for host mode? Or can I use this one while I also have HDMI out?
http://www.amazon.com/Menotek-Adapt...1?s=electronics&ie=UTF8&qid=1325341220&sr=1-1
This one seems to be "certified" for the Galaxy Nexus and also has a charging port to use while doing HDMI output. Does the Samsung adapter come with this?
I'm most certainly interesred but I want more details before shelling out money, even if it's small money
Edit: Looked at the video and I see the USB port there. Still though, how does this play wtih USB host? Do I even need an adapter for that?
Using the HDMI adapter and playing games with a controller can only be done with a bluetooth controller? Is there any way I can use HDMI and a USB PS3/360 controller?
(using the PS3 wireless is not a option for me i cannot get the app and phone to work together)

to ppl with questions, i got the official samsung gs2 mhl adapter. its 11$.
http://www.ebay.com/itm/230721222527?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
works wonders. i am 4.0.2 stock.
it uses full hdmi. 1$ on ebay.
it has a charging port, but it shows plugged in as usb charger even when plugged into the wall. it only draws enough power to power keep the charge constant, that is your battery does not go down, nor does it go up. and no, you cannot connect usb host when watching in mhl mode. would have been cool, but doesnt work.
One more thing, apparently THE PHONE HAS TO BE PLUGGED IN FOR THE MHL ADAPTER TO WORK. So, unless you plug in the charger, the mhl adater wont give output.
i hope i answered all questions.
OMG I need me on of these. It's not a Amazon prime item so that mean I have to pay for shipping lol.
nice!

Wow. So emulator+wifi+bluetooth+mhl= dead phone. 500ma is not enough to keep the GN floating.
Seems like a huge oversight on Google's part or perhaps it's just a MHL limitation. I know data does not work, which is why people have to use BT. But 500ma, what a joke.
Can anyone else confirm this?
Awesome video and post, thanks!!
Does the MHL to HDMI work with Android Movies? I know on my stock Transformer TF101 HDMI out is blocked in Movies. ...worked fine for Netflix and others though.
As far as battery is concerned. Would it be possible to program the screen to turn off when viewing in HDMI and still view it on the TV? seems like this would cut battery consumption dramatically. If not you could set the screen brightness to as low as possible.
Thanks man! Gonna buy this ASAP

What a downer.
Great minds think alike though:
http://forum.xda-developers.com/showpost.php?p=20156851&postcount=46
So it looks like the only option is to use some sort of dual charging situation where one charges the MHL adapter and the other charges the phone via pogo.
Perhaps the native HDMI doc allows AC charging? I guess we will have to wait and see.

mhl cable issues

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

Getting MHL/HDMI video out to work

I have both a genuine Samsung MHL adapter and the S2 mhl adapter with the 5pin to 11pin converter and I've seen both of these work on other phones.
However, I can't get my video out working on my S3. Both of them connect and bring up active charge and indicate onscreen that "HDMI cable connected". So I know the adapter and cable is being detected but no signal on HDTV. The HDMI cable is good as is TV and monitor I tested on and of course proper input is selected.
Now as far as I remember as soon as it is plugged in the video should automatically show up on HDTV screen...correct? No TV out setting has to be turned on as in past Galaxy correct?
Fyi..I have multiple S3's but currently only have one on hand...its a 747m with KyanROM on it... so not stock..it is rooted and has KT747 9-18 kernel as well.
I have a feeling its the rom(and I could easily test this if I had other phones but don't for a while).
So if both MHL adapters are confirmed working and both the HDMI cable and TV are working AND even the phone states that HDMI cable connected, then what is the issue with no video display?

Do you have the power plugged in? That is, a AC/DC charger to micro-USB cable plugged in to the micro-USB port on the adapter.
Should work automatically
I just received the Min-Suit 11-pin adapter sold on Amazon. Mine switches on automatically as soon as I plug in the adapter. Of course, to make it work, you should first plug a charging cable into the USB micro port on the adapter and you should connect an HDMI cable to the tv. Also, make sure you're selected the correct HDMI input on the tv. If you do all of that, the picture and sound should start up as soon as you plug in the cable.
Unless it was a mistake, your OP says you have s2 adapter. From my understanding, the pins are different on the s3 and will not work with the older adapters.
If you read closer Woody you will see that he says that he uses an old MHL adapter, WITH the 5 to 11 pin adapter
That should work. But I think your ROM is the guilty one...

Dont give up yet, I thought I had the same problem, but my ballistic case was preventing the MHL adapter from going all the way in. I took the phone out of the case and the adapter clicked in. Worked great on the TV, but best of all, worked in the truck via a down converter. Had to play with it to get in deep enough (kind of phone foreplay i guess:laugh to work, but it does.

[Q] Motorola Lapdock & Note 2?

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..
anything to do with HDCP and chinese cable?...
I am trying to get an samsung official MHL or a smart dock to try out. (here in india smart dock is still not avaiable). My once route to get it is through china...

I use the Samsung SmartDock. I was able to get the Lapdock to show the Note 2's screen when connected via HDMI with a Chinese MHL, but I couldn't get the keyboard/trackpad to work with it.

Hi refer my link posted in my earlier reply... it is easy to get the OTG simultaneously with HDMI....
For me i have connected both HDMI and USB together with lap dock.
MY lapdock keyboard and mouse are working fine and i can see it with note 2 screen....
USB port is working fine with 2 pendrives attached......
The only problem is not able to get the screen in lap dock ....only green screen...
update....
Tried with S4. HDMI detected but blank screen.
When playing video once cable is connected S4 screen goes blank but still video is running but lapdock is blank....
Team,
I have updated Android 4.3 + rooted hoping that it should work with lapdock... Still no luck.. still getting green screen.
Any help or update?.
wilbr,
Whats your android version?
Is it rooted or stock rom?...
If you are using Aosp, mhl doesn't work with Aosp.

I cant post a link to it so you'll have to Google it sorry

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've already got a Bluetooth keyboard and mouse. I'm gonna order a MicroUSB to HDMI adapter and go that route. It'll be cheaper and less to carry. When I travel I'll just be able to plug into the hotel TV and go wild!
There's a YouTube video of someone demonstrating it, just search YouTube for "Samsung Note 2 Mobile Desktop with a Bluetooth keyboard mouse"

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
