The title says it all...
I connect my Gnex to the my hdmi tv and it displays perfectly,,, but as soon as I open a video ( recorded video or youtube) the video keeps stuttering...
The stuttering disappears as soon as i remove the hdmi connection..
Does anyone have a solution to this?
I'm running a stock 4.0.4 on a unlocked and rooted phone
anyone knows why this happens...or had a similar experience?
As the title states I got the MHL today. Output to a 73" 1080p DLP, 55" Samsung LED 7000 series smart TV, 50" 1080p Panasonic Plasma, and 39" 1080p westinghouse LED all produce similar results... and if I do say so myself, it's really bad.
Lets see where to begin:
The Good:
-Watching 1080p content from local or network storage produces a pretty good picture
-Text is sharp, webpages look great
-Phone charges while mirroring
The Bad:
-Audio output is descent at best through HDMI, when connected with a very nice surround sound decoder it only decodes as "multi-channel", so DTS and other streams are not preserved on output
-Lag. And let me say this again... LAG. Don't even bother playing a game, it's unbearable. The phone experiences no lag while mirroring, but the output is about 1/3 the framerate.
-Lag on movies. On every TV the lag was exactly the same, whether I hardware decode or software decode the lag is present. Youtube videos look laggy even.
-Netflix does not properly mirror. I presume this is related to HDCP or copy prevention, but streaming HD content to the phone produces a nice widescreen image on the phone, but the output to the connected monitor is pure crap. Take a nice 720p HD movie, compress it using the bitrate of a low quality MP3, transmit it via AM radio to your least favorite country somehow, and then watch it on a ****ty color TV from the 1980's. This is my experience with Netflix output. Also, you can tell it is not "mirroring" because when you tap the screen, the position slider appears on the phone but not the TV.
-Cannot turn screen off while mirroring
All in all, I'm somewhat pissed off. In its present state I would have preferred the phone not support HDMI. I would accept this as a "Oh hey the phone doesn't technically support MHL HDMI mirroring but we hacked it and look what we can do" but this is definitely not a finished product to advertise. Anyone else experience similar problems? Anybody have HD output with no lag? Maybe I have a defective MHL adapter/phone?
I think you may have a defective adapter/cable. I got the adapter tip today and most of your cons were nonexistent for me -
Audio Output - I don't know much about audio but I have a 5.1 surround sound setup and it worked perfectly.
Lag - I had 0 lag. I played a racing game and watched a few episodes of Breaking Bad (MKV so the phone was working hard at decoding it too) and I had no lag.
Turning screen off - I see this as a pro since you cant accidentally turn it off while mirroring
But this brings me to my point about netflix...
Netflix has been horrible with MHL on my last 3 phones, including this one. If I try to watch a 16:9 HD show on netflix through MHL, it plays fine on the phone but becomes 4:3 on my 16:9 HDTV somehow. I don't know why this happens, but if there was a way to make it mirror exactly what was on the screen, that wouldn't happen.
I'm actually quite pleased since the signal is very solid with this phone. With previous phones, the signal constantly dropped and reconnected. I tried every cable but it was a no go.
The Netflix I don't believe is the phones fault directly, I think it has to do with Netflix restricting output. As for the lag, I will return the unit as defective if I can and get another one. Hopefully that's the problem, the lag is incredibly noticeable for me. Audio wise, it's not bad, but I don't see why it can't just output (or at least give as an option) uncompressed audio from the source. My main irk is the framerate I've seen, hopefully it's limited to this unit. Anybody else experience lag or more importantly not experience any?
I ran Netflix ok.. but same ratio issues as above... didn't look great but was ok. Any regular video files looked great.. but I had to order 2 adapters before I got the right one.

I also received my MHL adapter in the mail today. I like the picture quality and sound quality on my 42" 720p plasma, but I am wondering if it supports headphone port output somehow.
I got a connector also, but does seem to work with my monocable NHL,

I have a Samsung mhl and it works great

I just used the official Samsung one today to deliver a training for a few new hires, and it worked perfectly. I had a full 10 slide powerpoint, afterwards I opened up the camera app and used the connected LCD screen as the viewfinder.
Issues with the MHL adapter lag, and possible fix
I have noticed similar problems as the OP. About an 1/8 of a second lag when trying to play SNES. For those of you who wanted to retro game with a bluetooth controller (like a PS3 sixaxis) I was able to get it to work. It could be my TV, but I got the lag down well below a second, enough so that you can play a game like donkey kong country and dodge opponents. The game plays at 30Hz which isn't the best frame rate, but fine for SNES.
The TV is a Samsung 1080p and there are two options that I enabled that seemed to help; video game mode, and BD mode. I don't think the TV should matter but I thought I should mention this. After much tinkering I realized that the phone is sending two different streams instead of exactly mirroring the phone's own stream. I think this is the case because when I was playing with settings I noticed in some cases it would send a landscape view to the TV when the phone's own display was in portrait mode. There were a couple other things that indicated that this is the case.
The Fix:
Anyways using a third party app like Titanium back up you need to freeze almost everything, anything that is not essential to running the game of your choice; this includes things like Verizon bloatware, Samsung bloat ware, s voice, maps, Facebook etc. You also have to turn off things like wifi, GPS, sync, etc. I also enabled force GPU rendering in the developer settings. Make sure you don't have a live background running. I also overclocked my phone to the max with setCPU. Also if you use an app like nova launcher you can make a back up of your settings and app placements which you can restore to keep your icon placements. I realize this is not a very viable fix, but this seemed to work for me.
End Fix
It's a pain, but worth it if you want a portable retro game machine. Samsung or someone at XDA needs to look into fixing this because I am pretty sure it is a software related issue. I hope anyone who bought a MHL adapter and wanted to retro game finds this useful.
So with the guys who have good results where you ordering it from.

Hey just an update for anyone having issues such as screen flashes and lag I did a little more research and found in Samsung documentation that when connected to hdmi the s3 disables the output when a text or phone call is received but this was not implemented. I found that the device still checks for phone use and texts when connected to mhl. I actually had random screen flashes at set intervals on my TV! I disabled the phone and sms and this seemed to stop the flashing and help with some lag. I also noticed if you restart the device with the MHL to hdmi cable inserted the connection is a tad better and it also fixes screen flashes. I wish the damn thing worked and I have already replaced the MHL to hdmi cable twice now, and the slight lag (noticable when gaming) seems to affect a lot of people. It could be a problem with the actual device and not the software which would suck

I have tried just about every infected ROM, plus some other ones (Mahdi and Candykat) with different kernels (mani and redkernel) they all have the same issue.
When I go onto the Twitch app and go into a game stream and change the quality to Source (which I assume is 1080p) after a while the video starts to lag, sound gets choppy and unsynced, and after a minute or so the stream just stops.
This doesn't happen with Stock 4.4.2 ROM though, so anybody have any idea how to fix it?
Thanks.
Is anyone else having Bluetooth audio problems on 5.0? I can play music and video just fine over Bluetooth, but whenever I launch a game like Real Racing 3 my audio completely breaks up, and is unusable. It's not stutter every few seconds, it's a constant break up of the sound.
I've tried a few different games, and two different Bluetooth audio devices, no joy.
Odd thing is, this issue is the same when I try to do a screen cast to my chromecast. The audio is completely messed up and stuttering.
My N7 2013 is on stock (no root) Android 5.0. I did a clean install, formatting the entire tab. I have very little installed on it. I've done some searching here and on Google but all the posts relate to the 4.4.2 update, and was meant to be fixed...
My AFTV2 will not playback video from any source without the playback pausing/stopping for about 1-2 seconds all through the movie. No matter what the source whether streaming from my NAS or streaming from an app, any app. I play the same video back on my AFTV1 and it plays fine. I can't even play 720 video back clean let alone 1080p. I am rooted on 5.0.4 I was thinking of unrooting and going back to 5.0.3 but I would rather not have to do that. Anyone else having issues with video playback on AFTV2? or can anyone suggest what I can try to correct it. I have already tried playing back video using MX Player and VLC. I thought VLC might work because its the one from Amazon Play Store but the result is the same. It's really driving me crazy because it happens all the time. The reason I got the AFTV2 was because I thought I would get cleaner playback of video based on the new hardware, but my AFTV1 which is also rooted blows it out of the water. The Fire TV 2 is connected to a powerline adapter, but I tested it connected directly to my router and the result was the same. Even on the powerline adapter my speed test is about 19-24 mbps which should be fast enough to playback video smoothly. Any help or suggestions would be appreciated.

So.....no one else has problems with video playback on the AFTV2? If not then maybe it's my particular box that has a problem...

I just stream using Kodi & some addon sources you will get buffering problems but to be honest it's fine when you get a nice stream.

thanks for the reply. Yes I use Kodi as well, and you're right you have to have a good stream first. But even when I stream movies from my NAS in Kodi, or select a stream from an addon that's say MQ it still stutters throughout the movie. When I play the same movie, same stream, from my AFTV1 it plays perfectly fine. I know I have a fast enough internet connection. It just seems strange to me that the AFTV2 with the more powerful hardware can't come close to the AFTV1 when it comes to video playback. Even Netflix stutters.
