I've regularly been using my MHL port to transfer video to my TV's - and to my girlfriend's tv when visiting.
Recently - after finally rooting and using a couple different ROM's, I'd noticed my MHL output had steadily gotten worse. First it was a matter of the audio not getting transmitted with the video, but usually disconnecting and reconnecting and/or resetting my phone would restore proper HDMI output. But eventually, my Toshiba TV was not registering input at all. Testing on my LG TV - I get a scratchy signal and may lose it all together while jiggling the phone's USB port.
I've tested with 2 different HDMI cables, and 2 different MHL adapters. The results are similar. Actually - with one of the adapters I no longer get a signal at all, with the other one I get a good deal of snow and audio crackle. Which is odd, because I thought that being digital - I'd get a signal or nothing?
I'm pretty sure it's a hardware issue, but does anyone think going to another ROM might help? Perhaps usb or mhl drivers getting screwed up? Failing that - I'm thinking of going to a Sprint service center to see if the USB port might be replaced under my insurance coverage. Any advice?
Yes, go back to stock everything and see if that resolves it. I've found some roms and kernels and different combinations break mhl or make it unreliable.
In fact, I had the same EXACT things happen you're describing. Couldn't get it to display to the TV. I gave up, then tested it on my pc monitor that has an hdmi port, worked every time. Then I thought it was the tv or something. went back to the stock kernel eventually, it worked perfect each time. I'm stock everything with a few minor mods, works great.
Hmmm, that's odd - I'll have to go to a mostly stock rom then. Which one do you suggest?
I'm literally stock, no variation. Just added leeroid tweaks and a few app mods, that's it. Not sure what else would work.

I've had the official Samsung MHL adapter for a few weeks now. But just recently a problem has developed. Basically WiFi no longer works when the adapter is attached. For instance I can watch Netflix through the phone, then connect it to the TV and it'll stop. I've also tested surfing, disconnected from the TV I can surf fine. But as soon as I connect the adapter nothing loads. The WiFi symbol is still visible and connected, but it won't give me any data.
As I said this wasn't a problem until very recently. I could watch Netflix on my TV through the same phone (on three different TV's). Now on the same TV's it won't work. I haven't changed the phones firmware/OS or any settings AFAIR. Also everything being used is an official Samsung product (including the power adapter in case anyone's wondering).
EDIT: Tested mobile internet (3G) and it still works with the adapter connected. But when I tried to turn WiFi back on it won't connect until I disconnected the adapter.
EDIT2: I tried just plugging in the adapter with the plug in but without having it connected to the TV, WiFi then works normally. Its only when the HDMI cable is plugged into the TV that the problem occurs. I also went into WiFi settings on my phone and noticed it was stopping at "authentication". So I disabled security on my router temporarily and then WiFi connected with everything plugged in, but still no data, web pages still won't load. This is quite baffling.
It happened to me too. Actually, I bought two identical MHL adapters (same brand, same model...) from brando workshop. With one the condition occurred. With the other one, no wifi problem at all. At that time, I assumed it was a faulty MHL cable and didn't care. But considering that you suffered from the same symptoms, I believe that further investigation would be nice. At this moment, I have no clue on what could be causing this weird behavior. Hope more people can contribute on this...

I'm having the same issue, though with a brand new generic MHL adapter...
All my searching points to using nothing but samsung MHL adapters and power bricks being a possible solution.
Also Samsung's only suggestions are wifi dropout is normal and to use samsung adapters only...
IMO this is bull****, MHL is a STANDARD now, if I have a device that meets said standard it should function without issue.
How would you feel if you bought a samsung laptop and the USB ports only work right with samsung mice and keyboards even though they advertise standard USB ports...
Also I find it odd how I've managed to get pandora to stream music while I have my MHL cable connected some times, yet others data drops completely.
It seems more likely to drop out completely when my SGS II is decoding video+audio rather than just video.
Also, on the rare occasion where my data connection doesn't drop 100% it slows down massively, going from 2meg down to .2 meg down right after plugging in the MHL adapter.
I've tried multiple power sources too, from wallbricks, to desktop computers, to my macbook running on its battery to just an external USB battery pack. So I'm pretty sure it not a power noise issue...
Seems to me that Samsung needs to work on some software fixes...
Higher mA plugged into the MHL adapter may help. If you're only plugging it into usb (which I believe only outputs 500 mA), that could be your issue. I don't have any issues when using the AC adapter out of the box.

Are you using a original or generic mhl cable?
Nevertheless, i read some people saying that with some versions of Siyah Kernel and a 1000ma managed to resolve the issue...
I'm eager to solve this because my bluetooth keyboard with touchpad are arriving soon...

Found this charger: http://www.ebay.co.uk/itm/USB-Wall-...K_iPad_Tablet_Accessories&hash=item27bfeb2ecf
Any toughts? Since it has 2.1mA, can this harm the mhl adapter? And can i charge my SGS2 with this item?
Thanks!

Hope it works for at least some of you
It works for me too.
I have the SGS2 with the latest 4.0.3 rom.
I think this is the solution for everybody. No need for different chargers or MHL adapters. Just find the channel that works for you.

You change the channel on your wireless router. Every router is different. Depends on what kind you have. Google how to do it for whatever model you have.

I've done, changed channel in wifi setting, and It's Solved , THanks so much
same but different...
I'm having similar sort of symptoms, but I can't quite isolate if its the same problem or not. It definitely wasn't cured by changing wifi channel unfortunately :/
Here's the deal:
I use ps3 media server on my pc to stream to devices around the house. The SG2 (i9100) is rooted, but standard rom and mostly stock. I have been using bubbleupnp as a client for ps3MS and either Vplayer or Dice Player as the video player. ALthough lately its been a bit stuttery, overall it works and plays either saved mp4 videos, downloaded music vids and stuff just fine.
I have a generic MHL adapter and a hdmi to dvi cable that I use to connect to a spare PC monitor. I plugged some spare PC speakers in the headphone socket and was prepared for viewing heaven.
The monitor mirrors the phone screen fine. I can browse the PS3MS fine and select music and it will play fine. If I play a movie off the SD card (internal or external) again its all good... clearly I don't have the wifi stopping when the mhl is connected....until... drum roll and thunder....
I select a movie to play over the bubbleupnp, then it all turns to custard...kinda, basically the phone either stops and thinks for a while, then returns to the directory tree in bubbleupnp, or just sits there on the loading screen. Dice player definately takes longer to decide its not going to do anything than vplayer, but the results the same. Every now and then I get a network error, but not all the time. Sometimes when it returns to bubble, I find that the PS3MS can't be detected either, which usually takes either a few minutes wait or a restart of the phone...
Anyway, would really appreciate any thoughts and advice. While I've found plenty of threads about mhl problems, they seem to be all or nothing. This one seemed the closest to my problem. At the moment I'm a bit unsure what part of the setup is causing the problem; it definitely seems to be something to do with how it all fits together.
I've searched for problems specific to bubble and mhl, or bubble and ps3media server and all seem ok, or at least other people have them working...
Thanks.

thank you so much.
I just got a generic MHL from Ebay and got very upset when I wasn't able to stream from my network drives from neither my Galaxy Nexus or my wifes SGSII and changing from 8 to 4 solved it.
=]
ive had my MHL cable for over 2 weeks now and its got the official samsung logo - and i got it from suntekstore... only problem is i havent got it working...
ive tried with my dads stock 2.3 i9100 on a viewsonic monitor and samsung tv
same with my 4.0.4 i9100 resurrection remix 1.7 + siyah 3.1.2
the other two items i got from suntekstore were 2 OTG adaptors which fail to work... (i also have one that does work from another store) so i think it might be the MHL adaptor itself
yesterday i was frustrated and kept plugging my phone in and out of the samsung tv.... and BAM i got a visual =S after like 10 'no signal' and 2 resolution not supported... but the screen was stuck in portrait... thats the closest ive come to using MHL properly!
on top of that... when i use OTG keyboard connection... the phone freezes if i try pressing caps lock to check for power on my phone! any one else running same OS version and its working?
When successfully connected via MHL the S2 will display in portrait, so that was normal. Apps that run in landscape will do so when run, or where sensor orientation works, like in photo gallery etc, you can rotate it to landscape yourself.
No, as for your issues regarding getting the picture to stay on; first, you did have the Samsung Charger plugged into the MHL cable right, and the correct output channel selected on your tv?
Assuming you did for both the above, the problem is likely with your hdmi cable, not the tv's. Have you tried using different cables? I have a problem with one of my hdmi cables where the screen goes black for a few seconds whenever it pleases, with another cable (which comes with the sky box), it stays on all the time. So try changing cables and see what kind of response you get.
Also, some users have mentioned that they seem to get picture when they put their phones into flight mode first, I've never needed to do this, but give it a go and see what happens. Once you've got your picture up, you can use your tv's remote the control your S2, assumming your tv supports that function.
Hope that helps
I have not tried that rom but last I heard any source based rom doesn't have a working MHL output. I don't know the status at all of OTG on source based roms.
You said you tried it on your dads stock phone but didn't clearly state if it worked or not which it should if the phone is stock. So use that as a basis of if the adaptor is broken.
thanks guys - yeah it could be the hdmi cable... they are pretty cheapo - but on seeing 2 OTG adapters from the same store dont work... the MHL being broken cant really be a coincidence? it was in delivery for over 1 month =[ maybe someone broked it! lol
I think in the end it was the MHL adaptor... ive got a replacement sent out as now the phone wont even recognise power to charge when plugged into the mhl however the charger directly into the phone works! argh may be a long wait for the replacement took 30 days to get my other shipment! may have to resort to a more expensive one
Hi...sorry if this is the wrong place, but from my understanding they are the same phone and I didn't see any category specifically for the evo v...
At any rate, so I bought an ikross mhl to dvi adapter, hoping to connect my phone to an 18" LCD I have, but so far no luck with any of 3 monitors. I've connected the phone to a wall charger and tried hooking it up in different orders, to no avail...basically have followed every suggestion I can find.
I've now purchased an mhl to hdmi adapter from newegg for my TV and hopefully will at least verify the general functionality is working (when it arrives on the Monday following this post), but eventually would prefer it on the monitor. I also bought an HDMI to DVI adapter, just as a long shot.
I scoured google before I bought the adapter and every indication seemed like it should work fine, and now have scoured google + these forums again, but just not really finding much info related to my specific hardware.
The phone is rooted, running the latest Harmonia rom and is S-ON...I don't think that would affect it, as everything else on the phone so far has worked flawlessly, however, can't rule it out. There is a guide floating around on how to "turn the evo v into a evo 3d", so if this is rom-related, it's something to try? Requires going S-OFF, but even if it didn't fix anything, at least I'd get the radio updates. But again, from my understanding, the hardware is identical and this phone should be able to do standard mhl, so i assumed mhl to dvi should work as well, but I'm a little unsure about the standards...
Any insight is greatly appreciated and as I always do, if I find a solution, I will post
Still a no-go with an MHL to HDMI adapter, connected to my TV. The closest I came, was the phone went into dock mode if I didn't have the charger connected. Oh and if I unplugged the HDMI cable from the adapter, the TV would say check cable...So the TV was aware that a device was connected, thus it seems the issue lies in the phone.
Anybody have any idea what I could be missing? This /should/ work - the Virgin Mobile site even lists hdmi output as a feature of this phone, but no further mention in the manual and as I said in the OP, spotty info around the web
UPDATE: Just tried it with a monitor again, using an HDMI to DVI adapter, with the new MHL to HDMI adapter, and it almost wants to work - the monitor stays awake (not saying "no signal") and the phone registers that it's connected via hdmi, but the most picture I can get on the screen is but a flash when I change the phone's orientation =/
A second hdmi mhl adapter that I had ordered arrived today (was not expecting it for a month or I wouldn't have bought the other one...oops) and it works on the tv w/ full mirroring
Still a no-go on the monitor - it does the same as the other adapter. The phone and monitor both know it's connected, but only occasionally flashes of video appear and rather than any mirroring, the phone just says "play a video or slideshow" (which does not work).
So I guess the moral of the story: if you have an HTC EVO V 4G from Virgin Mobile (which is more or less the same phone as the EVO 3D) and you want to hook it up to a computer monitor: good luck! I mean, I'll test some more with other monitors on this new adapter but not getting my hopes up. Will post any positive findings, tho...
On the other hand, if you want to hook it up to a TV, it's just a matter of finding the right adapter...in my case, it was pretty much luck of the draw. One worked; the other did not. Maybe the other one will magically start working or will work with one of the new TVs I bought, but we'll see...
Anyway, here is the specific adapter that is working for me: not allowed to post links. Sorry! You all lose. Thank you spammers.
you also need to be on jellybean, or higher for the hdmi to work I do believe, otherwise the phone os if below doesnt recognize or work for hdmi out. the jellybean update made it so anyphone with micro usb out should be able to connect to hdmi with the mhl adapter.
I think its simply a matter of analog vs digital video signal. A computer monitor will need a digital video signal but a TV will be happy with either analog or digital. And I'd guess the output of the MHL adapter is analog.

I have tried HDMI out on 3 TVs and it only works on one. The one it works on is the newest one by a few years.
On the other TVs the results range depending oddly on the cable. A $30 Rocketfish cable I purchased for testing and now returned resulted in zero output on the other two TVs. My cheap cable will make some crackling noises and the screen will flicker on and off.
No output at all through my my receiver.
On the third TV... a 2012 model I believe, it works great. I have never had any issues with HDMI out on the other TVs although I only use an older laptop and a PS3.
Any clue what might be going on? Do I have a bad device or are my older TVs not compatible for some reason with the Tegra 3 HDMI out?
Thanks.
I finally got through to Hisense support. Major PITA as they disconnect you after a minute or so of hold time. Not like I expected anything different. Regardless they guy had no idea about any issues.
I'm going to go and buy another from Walmart and see if it has the same issue or not.
Went and bought another one to test the HDMI out with.
Same issue. So this tablet has problems with some TVs. Searching a bit further it seems like some android devices regardless of manufacturer have HDMI out compatibility issues.
Chromecast should hopefully solve this issue anyways.

Chromecast works great with this tab. Havent tried the hdmi yet.
I've seen some strangeness of a different type. When I plug my Sero 7 Pro in to one of my TVs with a particular cable, the touch screen starts acting funny, meaning a touch registers as a swipe and we'd things like that. Anyone else seeing weirdness like that?

HDMI issue
I am having an HDMI issue. For me, whenever I connect an HDMI cable to any HDTV and use Adobe PDF Reader while scrolling and zooming in I get all kinds of artifacts and glitches on the tv screen but not the screen of the tablet. I've used two different tvs and they both react in the same way. These jagged lines appear on the screen while zooming and scrolling but disappear right after i lift my finger off the digitizer. I haven't tried many other apps but it seems like its solely Adobe PDF Reader reacting this way. The few other apps I've tried do not react this way.
Would this be caused by...
The tablet itself?
The current software/os version?
The hdmi cable?
The tvs?
Model number: M470BSA
Android version: 4.2.1
Kernel version: 3.1.10
Build version: P756.6.02.11.00
I just bought the tablet a couple days ago and was notified of an update, P756.6.02.20.00. Should i go ahead and apply this update? or has anyone experienced this issue before and found a remedy? Any help regarding this minor but annoying issue would be greatly appreciated.
Different cables with less or more quality is not odd at all really.
I would not be surprised to find out that all your problems are from the cable you used and/or the tv you tried to use and not the tablet.

There are definitely issues with the Sero 7 Pro and older TV's via HDMI out. In my case, I'm lucky enough to get a picture on the screen, however it fails back down to 480p which is just unacceptable.
With that said, there is some hope. The issues that I am experiencing do not seem to be directly tied to a hardware problem, but rather software. Via rooting and trying a custom rom, that is not based off the stock rom, I was able to get a 720p picture on screen though there are other issues

I have a small, cheapo TV that causes problems with my touchscreen whenever I plug in the HDMI cable to my tablet. Plug it into my big Samsung TV and it works great! Weird, eh? The small TV causes the touchscreen to register taps as swipes..

The touchscreen being erratic happens on a few of my other older devices with HDMI & MHL connected too. It seems that most of these haven't been tested extensively in this mode. There's a ground connection problem, I remember it was better if I connect a charging cable also, or holding it slightly differently or setting it down when using the touchscreen & HDMI connected.
Erratic screen problems
I almost returned my tablet today. I have three of them and only one exhibited erratic behavior while using HDMI out.
The screen would barely respond to my touches. It would misread and select the wrong things. I couldn't play games or scroll the screens. A mouse would work but not touching the screen.
It turns out the erratic screen problem goes away if I turn off the Sony Playstation 3.
This time I tested it and it is repeatable. I had both the cables plugged into the TV next to each other so now I separated them.
Now that I think of it I remember seeing a video about a guy who thought he had screen problems but it was interference from a nearby computer.
I found the video I remembered of the guy who was having the same problem due to interference from his computer. He demonstrates the erratic screen behavior and says he returned his tablet twice thinking it was faulty.
I can't post the link...oh well. You'll have to look it up.
I purchased the Amazon Basics micro HDMI cable (http://www.amazon.com/AmazonBasics-High-Speed-Mini-HDMI-Cable-Ethernet/dp/B003ES5ZR8/ref=sr_1_1?ie=UTF8&qid=1419968500&sr=8-1&keywords=mini+hdmi) and I've been having issues with poor or no connection. The first time I connected the tablet everything was great. I played about an hour of Portal with no issue. I had to reboot the tablet, and after that I couldn't get a signal. I tried the HDMI cable in my Canon 70d and had no signal. I assumed that the cord was bad, but last night I tried again and got a good signal for about ten minutes. I had to change the source on the TV and when I went back to the original input, my signal was gone. Has anyone else experienced this with the Amazon HDMI cable or any other HDMI cable? What are some good low-cost HDMI cables that others have had success with?
Ive used this adapter a few times without issue. http://www.amazon.com/gp/product/B00IZYIYX8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 .. If the cable is giving you an issue with multiple devices can it be the TV?

I plugged the cable into all of the HDMI ports on the TV and one on my Sony receiver. It seems to react the same way with both devices. But that adapted you linked looks pretty slick.
Sounds more like a bad cable than anything else. If you replace the cable and it continues then the shield would be the next more likely culprit. I haven't heard of this happening to anyone else, though.
