Hi guys,
I just bought my hdtv adapter in order to connect my tab to my TV trough HDMI and happily see netflix everynight..... The thing is that for any reason when I plug the cable de image in the TV is a clone of the image in the tablet, but the uggliest point is that when I put a movie in netflix not only the image in the TV is not escalated ( I see the movie in part of the TV screen) but subtitles are not in the TV screen but they are in the tablet.
Any idea how can I can get it fixed. Is there any hdmi output control software or something like that?.
I'm trying yo get my TV dispay as an extension of the galaxy note display.
Thanks!.
I just found out, to my disappointment, the same behaviour with netflix and the allcast dongle.

do you think it's a netflix app issue or the hdmi output resolution that it's unable to fit the whole tv screen?. I hope there is a software to fix it.
Unfortunately, I do not have a clue. I will probably try and buy an android stick to bypass the problem

I would have expected stock was better than this. Seems like a lot of devices have issues with UI overlays and HDMI output. Sounds like even Samsung's stock hwcomposer is a steaming pile of ****. Or this is one of the consequences of Netflix's weirdo JPlayer.
Oh wait, never mind, stock is 4.1, JPlayer isn't used... Probably just Samsung brokenness.
For example, my Xperia T has the following issues when outputting Netflix over MHL:
UI overlays do not appear
Anamorphic video is not scaled properly. (For example, Star Trek: Enterprise on Netflix is anamorphic 640x480 video - e.g. it is stretched to display as widescreen and the pixels do not have a square aspect ratio, but when output over MHL it is displayed as if the pixels were square.)

Yeah, that what I've just noticed. The UI overlay does not properly works... I can't see subtitles in my tv screen.
Isn't there any player or another kind of soft to play netflix movies thorugh? or even better, a fix to it...
BTW... i bought the hdmi adapter for my galaxy s3 and now the image in the mobile escales perfectly to 1080p however the overlay issue is still there..., I'M NOT ALE TO SEE THE #"!#$&/( SUBTITLES... :crying::crying:
I hope there's a fix.

Sadly, this seems to be inherent to the HDMI mirror process, as I get the same on my Xoom and all my Moto phones: clear audio and video, but no overlays (controls, subtitles, etc.)
same with Play Movies
I have the same problem with my note 2, note 10.1, over hdmi adapter or allsharecast dongle both with netflix and play movies. Subtitles only on the tablet.
I have contact samsung and google about yhis annoying issue and they both try to blame each other instead of giving me a solution.
What I don't understand is how such a basic thing is not possible
When you use BS player and software encoder the subs is showing in the TV and the phone-tablet. I remember it was the same with the first Nvidia gforce graphick cards with comp-scart output on windows XP. I think it is a hardware problem. I think we need a new genaration og GPU hardware. Question is, what about Nvidia Tegra 4 chipset phones or Shield device???
Have someone got an android phone (could be LG X2) with a real HDMI output purhaps it is a MHL-HDMI problem
It's a hardware issue, yes- the movie is rendered via the hardware-accelerated video channel that also outputs thru the HDMI (and/or Miracast) streams. However, since subtitles (and other such overlays) are decoded and rendered outside the main video stream (that's done on a seperate video channel) that's normally overlaid over the display stream.
This issue isn't limited to just Exynos chips, either- I know for sure the Tegra2 and one of the QCT Snapdragons is like this, too; I suspect the issue actually comes from Hollywood, as DRM protection implies you can't manipulate the buffer that's displaying the external streams (yes, even for your own (non-DRMed) content, sadly), but don't quote me on this.
In order for a player to give you subtitles that display on external devices they'd have to render everything in software, and I don't think every stream will play smoothly that way. I do remember seeing a video player that does do subtitles on the All-Share Cast stream; I think it was the Archos one.
I think what you most have, is just a setting problem.
I have galaxy s3 and samsung tv connected through hdmi adapter.
By default this behaves exactly as my windows media pc, app. 10 pixels are cut on all sides. When you change your tv settings not to overscan, the image is perfect. In samsung tvs (tested 50" plasma and 22" lcd) you do this in by setting the size of the display, from 16:9 to customized. I have Finnish ui, so i do not know the exact terms.
In this way most of the programs work ok, including e.g. Xbmc.
But this does not fix netflix, it is seen on tv as 4:3 without any subtitles. So i would blame netflix first.

I have a simple question and to be honest, I am a little surprised that googling the issue resulted in nearly no hits. So I am trying my luck now here in the forum:
Part of the reason to buy the Kindle Fire HD 8.9 was for me to be able to use it as a playing device for movies on my HDTV. I also bought the official amazon HDMI to Micro HDMI cable to connect the kindle with my TV. The problem I am now having is that my HDTV (Philips 52PFL9632D) produces two vertical black bars to the left and the right of the picture, i.e. it doesn't offer the full 1920x1080p resolution, but something a little smaller (I guess around 1700x1080p).
Yes, I tried all the scaling options on my TV to no avail. And my Xbox, my BluRay-Player and my Dell Notebook do produce a flawless Full HD 1920x1080p experience on that TV Set on the exact same HDMI port. So it must be a problem of the HDMI output of my Kindle.
I suspect that the reason for that behaviour is the fact that the Kindle 8.9 display features a resolution of 1920x1200, which is not 16:9 but 16:10.
So as a result my TV probably squeezes the picture to fit it and thus produces the black bars left and right. It also doesn't matter if I am playing a video using VLC, surfing the web with Silk or just display the Kindle App selection screen on the kindle. There are always the black bars left and right.
(BTW: amazon customer service acknowledged the problem, but couldn't find an immediate resolution and promised to call be back.)
Does anybody have any idea what I can do to get the full resolution on my HDTV? I was so looking forward to not having to unplug my Notebook everytime and hook it to the TV, but being able to use my Kindle for watching movies instead.
What I am really surprised about:
1. Why does amazon produce a default signal output on the HDMI port larger than 1920x1080 anyways? Most people probably would want to hook it up to their TV and except for some monitors I don't know any TV featuring a resolution of 1920x1200.
2. Why does the kindle not offer any configuration option to at least choose the HDMI output?
3. Why is the net basically not producing any results when I am looking for a solution for that issue? Am I the only one hooking up his Kindle to his HDTV? Or am I the only one having that problem? Or am I the only one being annoyed by seeing two vertical bars on the TV?
ANY help how I can get rid of the vertical bars would be greatly appreciated!
I am going to throw a guess at why its not full 1080, someone can correct me if I am wrong because like I said this is just a guess. From what I heard, the kindle fire HD 8.9" model uses a set amount of ram towards the GPU to render out in the resolution it uses, and from what I read it was just barely enough memory for it to use that resolution, so using anything higher than that would probably not be possible. Lemme see if I can find where I read this.
Edit: found it!

The wallpaper service public APIs were selectively disabled to alleviate the memory pressure on system_server. Amazon's default Kindle Launcher doesn't need wallpapers (yeah I hear you when you say apps with FLAG_SHOW_WALLPAPER however do need wallpapers... but that functionality was apparently deemed not *that* important).
We freed about 14MiB+ worth RAM from system_server. This change was primarily targeted at the 8.9 Kindles, as 1GiB RAM was barely holding up to Kindle's massive resolution.
I see that having a bool in framework had work cut out for you guys... so I guess props for us to have made it "configurable" eh?

Interesting theory. But I read elsewhere that amazon claims the output of the HDMI socket of the Kindle Fire HD 8.9 would be FULL HD.
I think that the output is in fact 1920x1200 (equaling the native resolution of the kindle display) and thus even MORE than full HD, which is only 1920x1080. And my TV is trying to sequeeze the full 16:10 information into the 16:9 screen and as a result has to display two vertical black bars left and right. So I am looking for a way to actually REDUCE the output of the HDMI socket to the lower (HD standard) 1080 instead of 1200 pixels.
Well I seriously have doubts about this working on amazon's stock os, but supposedly the full version has experimental support for HDMI resolution changing. Give it a shot, though if it doesn't work on Amazon's os I'm more so convinced it will on cm. https://play.google.com/store/apps/details?id=com.nexter.miniscalerfree

I actually have had very similar problems using my Sony television. I'm curious if you ever found a solution.

My Kindle is rooted, so maybe it works. Thank you very much for the great tip.
I asked the question in the ROM-AOSP CM10.2 forum, since they even have a line under features saying
"HDMI video out is now correct and work across several resolutions. YMMV"
but so far nobody in that forum cared to answer...
I will try out your tip asap and report the results here.
Still I am wondering why I only found so few hits for this issue including in the amazon.com kindle discussion forum.
If nobody uses their kindle to connect it to their TV, why is amazon selling their own branded version of MicroHDMI-HDMI cables?
Ok. Time for an update. I think I am a step closer to a solution.
First I tried the app "Resolution Changer Lite" as recommended by stunts513. In theory it looked great. I was able to select a resolution 1920x1080 and as a result the kindle had a black bar at the bottom and only used 1920x1080 of the 1920x1200 pixels on its display.
So full of expectation I connected the Kindle with my TV. Unfortunately the TV still displayed black bars to the right and left but in addition now also a black bar top and bottom. So while it indeed reduced the displayed area, somehow the Kindle seems to still send the 16:10 information throught the HDMI port, making my TV scale down the picture. I tried all kinds of settings and resolutions to no avail.
As a next step I bought the full version of "Resolution Changer", because it was talking about an additional HDMI feature. Again full of expectation I started the app. Instead of selecting one out of several preset resolutions (like 1920x1080 or 1280x720) the app allows you enter any values for Width and Height. I again tried 1920x1080 with the exact same result as in the lite version.
But the full app has a second tab called "HDMI" and I did the same thing there. Unfortunately again to no avail. After some testing and reading of the description I came to the verified conclusion that all this additional feature does is DETECT if somebody connects a HDMI cable to the port of the Android device and then AUTOMATICALLY changes the screen resolution to the values chosen. So instead of having to invoke the app manually every time you in theory just set the wanted values on the 2nd tab and any time you plug in your TV your android device switches to the defined resolution.
Unfortunately there is no value to edit to stop the Kindle from sending out a 16:10 information to the TV or the app maybe doesn't even change anything that is sent to the HDMI port, but only influences the built-in screen.
But then unexpectedly Amazon's Customer Service sent me a message! They basically confirmed that if you connect your Kindle to a TV through HDMI it sends out it's 16:10 resolution and thus makes your TV scale down the picture.
BUT when you switch to the NATIVE INTERNAL VIDEO APP, the signal sent to the HDMI port automatically switches to 1920x1080 and a 16:9 ratio information. So as a result the native amazon services like "instant video" or other streams will be displayed without any bars. They claimed to even had it tested on a LG Full HD Plasma.
THIS EXPLAINS WHY MOST PEOPLE DON'T HAVE ANY PROBLEMS and thus you can't find much about in the forums.
I have to say I was sceptical, but since I had only used VLC so far to play back the movies, I now used the original video player. And to my surprise the black bars left and right went away and I had a full screen picture!!!
That's why I am saying, I am one step further!
Unfortunately this only helps me partly. For starters VLC plays a lot more formats than the native video player app. In addition I like to watch the movies with subtitles since I am not a native english speaker. VLC plays them automatically if the .srt-file is named the same as the movie itself, but of course the native video player doesn't. I don't even know it is capable of that.
Anyhow the big questions I have now:
1. does somebody know how to make the regular android Video Player display subtitles for example in the format .srt?
2. is there an option in the Android version of VLC (I don't think so, since it is still BETA) to configure the HDMI output?
3. Now that we know, that the regular Video Player can influence the format sent to the HDMI port, is there an app to set the HDMI output permanently to 1920x1080 and more important 16:9 ?
Again any help appreciated...
Ah, I wish I had known you were using vlc I would have suggested a few things. It didn't occur to me you might be using it because I got my from the play store, but it said it wasn't available in the USA, so I had to proxy through another country to get it. Anyways, I know in vlc's options there's a few different output methods, though I don't think that will affect it. Another thing I was thinking of is in vlc, u can change the aspect ratio, I believe the button is on the bottom left above the playback bar while playing a video, when u tap it it switches they various modes, don't know if this will affect the HDMI at all though, as I don't have a minihdmi cable because most of my TV's are CRT, only 2 of them have HDMI plugs, and of those 2 only one has 1080 capabilities, and its a PC monitor so it has no sound output.

Hashcode's CM10.1 and HDMI 1920x1980
Hi Tronar,
Saw your post (http://forum.xda-developers.com/showpost.php?p=45044803&postcount=579) but I'm not allowed to answer in that thread.
I have Hashcode's CM10.1 (20130812) running on my Kindle Fire HD 8.9. I connected the Micro HDMI port to my Samsung Full HD TV, and also saw the 2 vertical black bars (about 2 cm). Using apps like Resolution Changer doesn't help, as I get some weird screen flipping, turning landscape into portrait.
Cheers, S

Well, plenty of stuff to respond to.
First of all VLC was available in the regular Kindle Store. So I didn't even have to root my phone and install the Google Playstore to be able to install it.
In addition VLC is still beta. The configuration options are quite minimal compared to the PC version.
And of course I tried the various screen size and ratio options in VLC. But they only affect the way the Kindle display of 1920x1200 is used, i.e. how the available pixels are filled with the video. So you can achieve all kinds of effects using only part of the Kindle display. But whatever option I chose, the black bars left and right always remained on my TV. To make it simple all I could do was further add more black bars by shrinking the image or distort the image by changing the ratio. None of it seems to have any influence on the HDMI output. I think it is a very special option or feature, the regular Kindle Video Player is using there and would have to implemented explicitly in the VLC player.
Nonetheless this gives me the idea to send some feedback to the VLC developers to add this feature to their wish list. :good:
Anyhow, I really appreciate your help. Please keep the good ideas flowing.

Well, it seems like nobody is allowed to answer in that read, because so far I haven't received any answer.
Neither in the CM10.2 nor in the CM10.1 thread, where there seems to be at least some kind of life.
Thanks for confirming that the Resolution Changer doesn't help on the CM10.1 ROM. That saves me hours of work of trying out that app on this ROM.
But my question was actually a little more specific. The first page of the thread states under Features:
"HDMI video out is now correct and work across several resolutions. YMMV"
I was wondering if that means that there is some way in this CustomROM to change the resolution of the HDMI video out signal.
Update:
I tried the App "MX Player" to see, if that app would behave more like VLC or more like the native Video Player.
I don't know if I should laugh or cry, but this is what happened:
I started a movie using the freshly installed MX Player and was happy to see, that the subtitles were showing on the Kindle Display. I connected my Kindle with the Micro-HDMI-Cable to my TV and was also happy to see that the vertical black bar were NOT showing, but instead it was using the full resolution of my TV. I was totally excited. And then it hit me:
While the subtitles were showing on the Kindle screen, they were NOT showing on my TV!!! Otherwise both screens showed an identical picture, but the subs were missing.
So I tried out all kinds of options in the subtitles settings. To no avail.
Then I tried switching from using the Hardware accelleration to Software accelleration. The app offers three modes called SW, HW and HW+
And here comes the funny part:
When I switched from any of the two HW modes to the SW modes, suddenly my TV was showing the subtitles. And for a moment I was like "Yeah, I finally found the solution". And then it hit me: now my TV was showing the vertical bars again.
My conclusion from this test:
When you switch to software acceleration, MX Player behaves like VLC. You get the subtitles on your TV, but you have to live with the vertical black bars effectively reducing the resolution.
When you switch to any of the two hardware acceleration options, MX Player behaves like the native Video Player and gives you the correct 16:9 1920x1080p output on the HDMI-out. But for whatever reason the subtitles are only displayed on the Kindle screen and not on the TV any more.
My guess: by using the HW acceleration, the app automatically triggers the built-in feature of reducing the resolution from 1920x1200 to the standard 1920x1080 on the HDMI-out. Apparently amazon has built in that feature into the Hardware acceleration of the Kindle.
I don't know why this kills the subtitles. Either it is a bug in the app or for some reason the Hardware acceleration does not allow the blend-in of the subtitles over the video.
And when you switch to SW acceleration, the Kindle apparently thinks of the app like any other standard app and sends the full 1920x1200 resolution not only to its own screen but also to the HDMI-out.
It would be great to know, if superimposing subtitles is technically impossible when using the HW acceleration because the Kindle chips do not support that at all or if it could be achieved with the right algorithm.
I am unsure if it is the exact same thing offhand but vlc has an option to enable hardware decoding, if it is the same thing try it and see if vlc works . also I don't know much bout HDMI, but if its a digital stream and subtitles aren't showing up, try enabling captions on your TV and see if anything happens, I would think that they would be part of the digital stream in one way or another.

Thank you for the tip with Hardware Decoding option in VLC, but unfortunately it doesn't seem to make any difference. The picture remains shrinked with vertical bars left and right, no matter if you enable that setting or not. The subtitles also remain visible in both settings.
So my guess is that the current VLC beta isn't really enabling the Hardware Decoding on the Kindle. At least not the way, MX Player and the native Kindle Video Player seem to do it.
About the subtitles still being part of the digital stream in the HDMI output: sounds like a great idea as well.
So I tried it out by activating the subtitle setting on my TV. Unfortunately to no avail. It MIGHT be, that the way US-TVs receive and display subtitles from TV broadcasts is different than the one used in Europe (here subtitles are sent through a quite old system called Teletext oder Videotext (depending on the country)).
Or it might be, that the HDMI protocol just does not support this way of transfering subtitles to the TV.
In any case, unfortunately I am not any closer to solving the issue.
But thanks for the good ideas and tips, please keep them coming as I will keep attacking that problem.
Hi all,
I am new to Fire Tv and Kodi, but have recently be trialing some paid sports apps as alternative to Sky Sports. I'm currently paying for Infusum and have just been trying out the service from HDTV (mbox hd iptv). I am playing back on my LG smart tv from 2012. The picture quality is quite good, but as soon as you get to any moving pictures, it becomes a bit juddery/blurry and difficult to watch. As this happens with both these add-ons, thinking it is either due to fire tv or tv itself (though all motion and added settings are turned off). I have read that some people not happy with playback on their Amazon boxes, so likely to be this?
Has anyone else got a football feed in HD running perfectly on their tv via the Amazon box and is there anything I can do in settings or addons to make this run better? (I have tried all the options in fire settings, ie 60hz, 50 hz etc and did not seem to make any difference. Such a shame but looks like Sky Sports is still only suitable source for me?
I also would like to know
Not sure if my issue is Kodi related or Fire TV related, but 3D MKVs (1080p SBS) do not work well on my Samsung TV in 3D mode through Kodi. They do display in 3D once I change the TV into that mode, but there's ghosting. Playing the MKV using the TV's built in Media Player has always worked fine. I suspect Kodi isn't converting the SBS video completely correct. OTOH, I had to calibrate the Fire TV due to my TV's overscan, so perhaps that has something to do with it? I'm not sure. Does anyone have any tips for getting 3D video to work?
You´re TV is using additional filters etc. when the playback is run internally but the TV does not use these for external input via HDMI. It´s most likely you would see this also with other external players.
Concerning overscan: when you don´t need it (for e.g. you´re not using any analogue video inputs), set it to 0 in you´re TV or deactivate overscan. It´s the better solution than to calibrate all attached devices for overscan which isn´t needed for digital HDMI input normally.

That's interesting because I have two different TVs connected through HDMI that both required the image to be reduced 2-3% with the Fire TV. That ought to be digital. Am I missing something?
EDIT: Okay, here's what I was missing. Both TV sets were NOT set up to the optimal screen settings. The Samsung was set to 16:9, which you'd think would be the right setting, but it's not. The "User setting" with the option to move the picture horizontally and vertically is the "correct" one to use. On the other TV that I was using overscan on had a similarly poorly worded option called "Fullscreen 100%" or something like that that gave the actual resolution instead of the default "Normal" setting. Unbelievable!
The happy ending to this story is that 3D movies work perfectly. I hear there is a plugin for Kodi to automatically switch the TV into the correct 3D mode assuming the MKV file has the 3D encoding option specified. (I went through and fixed all the MKV metadata to include it.) I'll try to find it and test it out.
Those overscans mechanism do imply scalers which may also corrupt the proper displaying of 3D content. I wonder why still today TVs are preprogrammed with overscan for digital inputs.
But you´re 16:9 issue isn´t clear for me. A 16:9 TV should display everything at 100% or is it a non 16:9 TV, for e.g. with 21:9 aspect ratio? In that case the TV probably tried to stretch the 16:9 content instead of letterboxing which may also lead to a bad 3D behaviour.

The default option on my Samsung 55" TV is "16:9". There's also "Wide" (4:3 stretched to fill the screen) and "Zoom" (4:3 zoomed so the top and bottom are cropped). It's not until you go to the "User" option that you realize that the default "16:9" option (the first setting) is actually zooming the image 2-3%! I can only suspect that Samsung assumed people would be watching a mix of analog and digital sources. You'd assume the cable company's box would take care of any issue with displaying analog signals to a digital TV, but I guess not. The moral of the story here is to not assume the TV isn't implementing an overscan on ALL signals by default.
EDIT: Apparently, my TVs are the only ones like this: http://www.engadget.com/2010/05/27/hd-101-overscan-and-why-all-tvs-do-it/
Is there a way to change the Pixel Ratio of video playback across the board, on the Fire TV Stick 2 through an ADB command?
It seems like 480p mode doesn't exist in the Fire TV Stick 2 after a recent update, it won't even show up in the hidden display option, so 16:9 appears all squished up when using an HDMI to Composite Convert to a 27" CRT TV, the only way I can change the pixel ratio, is when I use Kodi, but i have to load Kodi every time when watching Twitch streams, in Kodi I adjust the pixel ratio to about 1:41 in order to letterbox the 16:9 twitch streams.
So if there is some command to adjust the pixel ratio via ADB, it would help in my situation, I just need to adjust the pixel ratio, so that 16:9 videos is displayed in letterbox format on a 4:3 TV.
