As stated in the (www .blogtalkradio .com/motodev) Q&A session yesterday with Motorola about the Droid X, in answer to the question asked at the 29:00 mark,
"The only time that we are enabling the HDMI driver on the device is when you are in the gallery mode. [...] The HDMI driver is not active any time outside the gallery," where the "gallery mode" is their included photo/video viewer.
I'm wondering how true that is...
(www .pcmag .com/article2/0,2817,2365630,00.asp ) PCMag's review stated that the youtube player and blockbuster player were not able to use the hdmi out at all.
As seen in (forum.xda-developers.com/showthread.php?t=703111 ) this thread the evo 4g, which also has hdmi out, is capable of allowing any app that uses VideoView to utilize that output, but that's supported by the phone maker.
Will that usability be true on the droid x?
Could we figure out a way to bypass any limitations Motorola includes, and maybe even send (an upscaled version of) the main screen through the hdmi (not just video but anything we could put on the phone's screen)?
I was just at a motorola event and we were able to run nfl mobile through the hdmi.
Yes the tv was in an ice sculpture and yes it was connected to a droid x via the hdmi cable

That's great news, thanks for letting us know!
The more apps with handshakes to the hdmi-out we have, the better for us to get it working completely openly
The whole media-center-and-phone-in-my-pocket is just a great idea imho...
With the hdmi out we could:
put any videos and pictures from any source up on your home tv
connect it to the projector at work and give presentations
go with a few bluetooth controllers to your friend's house and play multiplayer (even online) games on their tv with minimal cords to deal with
maybe even video-chat would be possible if you set up the phone with the camera facing out in front of the tv
... ok, that last one sounds like a pretty lame way to get video-chat, but it would save on having to have a computer/monitor/webcam when you wanted to
Of course this is all far into the future stages of development on the phone, but I'd rather create buzz and excitement to build up a developer and user base
Talked to a moto rep, said it might have been a beta device as licensing is what will prevent this thing from being turned on when it hits consumers hands. At least we know it can be done.

no fun, i'm not much of a C programmer, but if it's just enabling or disabling the driver, I guess it comes down to the security on the phone. If you go into root, I suppose we should be able to start the driver. The only thing I fear is if the driver is signed and only a signed application can access it, then I think we might be SOL
I'm not particularly worried... if we get access to enough apps that use the hdmi driver, we should be able to document enough of the method.
I believe while the hardware can reject unsigned versions of the OS (roms), most apps are self-signed (see developer. android. com/guide/publishing/app-signing.html) so that shouldn't be a problem. We just have to figure out which hoops to jump through (following the programs that use hdmi) to get it to work. They'd have to leave the hoops pretty wide open or else risk the need of updating the thing every time a new app is released that needs to get through.
This is a mixed bag here. The reason why Motorola limited the hdmi driver is likely so they didn't have to put a fps cap on the droid x like htc put on the evo.
This is pure speculation here but I would imagine the way that the evo devs are going to "truly" overcome the fps cap is to mimic the droid x behavior of toggling on and off the hdmi drivers so that the evo can access up to 60 fps.
You guys are on the other end of the boat where by default your fps won't be artificially capped, but you likely won't have full access to the hdmi drivers at first.
I think the sweet spot for both phones is finding a happy medium where we can toggle the hdmi drivers at will.
Any news on this? I would really like to get rockplayer and youtube working through hdmi. In fact, I would like to get the entire OS through HDMI and possibly a bluetooth keyboard and mouse working so I can use it as a little media center pc.
2 way control
I would lime to see this pushed to.the level of controlling the phone through an hdmi touchscreen.
I thought we would be able to see pandora and other apps through the hdmi...This sucks the way it is...also does anyone think the sound is terrible through the hdmi?
There is no point int he HDMi at all if you can only use it for your pictures and your videos from the phone's camera.
They need to make it show what you see on the phone, but on the screen
I remember there was a windows mobiel program that popped up a small window on your desktop that let you see your phone's screen and interact with it on your monitor when connected through usb
anything like this for android?

Update: "Real HDMI" in the market
http://forum.xda-developers.com/showthread.php?t=769990&highlight=control+hdmi
Hi,
I'm pretty new to Android development. So my understanding after reading a couple threads here is that HDMI access on the stock Droid X is limited to the gallery only, is that right? And the point of the "Real HDMI" app is that it will automatically redirect all output to the phone's display through HDMI, right? So no API exists which gives programmatic control over the HDMI port? That's a shame if so.
Do any of the Android devices allow easier HDMI port control or do we need these kinds of work arounds for all of them?
Thank you very much for any information anyone can provide.
Sorry to be a pest, but can anybody answer my questions? Should I consider posting somehwere else?
Thanks again.

Maybe try posting in the Real HDMI thread over at DroidXForums.com because username GMAN (who made real hdmi) has a thread there. I'm sure his knowledge of the subject is pretty extensive.
I just picked up a Thrill and tried hooking it to my TV and it keeps saying no signal. Is it I have a bad cord or is there a setting I need to put the Thrill on to mirror it to my TV? I don't actually need to mirror it, I just wanna watch movies from it on my TV.
Please HELP!!!!

We have a couple more months till we upgrade TVs to get a HDMI capable TV. Would there by any issues with getting a converter to RCA jacks from the HDMI cable out from the phone?
If you find somewhere that sells Micro HDMI to RCA let me know. I mean I could always go to DVI but I would lack the sound.
From what I recall the actual device required to convert from hdmi to rca is quite expensive....it requires some sort of signal processor box...
but I could be wrong.
http://hdmitorca.net/
It does require a processor box, because you need to transfer Digital signal (HDMI) to Analog signal (RCA). That's why You won't find just a simple hdmi-rca cord.
the converter boxes can range from cheap to expensive depending on quality, and if you are looking to scale up or down. IMO with down scaling quality is not as important as with up scaling.
I cant seem to get my hdmi to work either I guess i'll try some of the suggestions here
Any other suggestions, I cannot get it to work and I tried all the suggestions here, Do I need to be in a specific program for it to work?
try Post #7 on fist page of this thread. also some tv's don't pick up automatically what is being broadcast as far as the signal. you may have to play around with your hdmi output settings to match your tv.
Some hdmi tvs have to have a firmware upgrade i cant connect my fios tv box to mine without doing an upgrade according to the fios guy i gotta use the old rca style hd cables

Is it just not possible to mirror hulu plus via HDMI? The best results I found said that it's just a matter of processing power and even the Bionic isn't up to the task. It's nice being able to stream hulu on my phone, but it would be even better if I could just connect it to my TV to watch everything too.
If there is a way to mirror with hulu, I would appreciate any help is far as pointing me in the right direction to get this working. If it's simply not possible at this time, then I guess I'll just have to live with that fact lol.

I think I found the thread you're talking about. If you're talking about the xternal display app, then it doesn't seem to be working for me or I'm doing something wrong. I've tried enabling it before plugging in the hdmi cable and after plugging it in. If I ignore the stock mirroring pop-up window, it just displays the red moto logo on the TV. If I select the mirroring option in the stock pop-up, xternal display says an error occurred and then hulu displays the same message saying that mirroring is disabled.
i couldnt seam to get it to work, sorry. you can always flash the webtop hack and watch hulu thay way without any docks just hdmi cable. i know that works for sure cause i watch it that way myself

Thanks for confirming that doesn't work.
When you run it on webtop, are you using the hulu app or pulling up the hulu website? I tried running the app in webtop and it still pops up with the HDMI out disabled message.

Well i'm happy with a setup i've just done. Using my X Mini portable speakers I get a very loud speaker, with high quality. If anyone else cannot be bothered/cannot figure out how to fix HDMI, these are probably better than my Tv's speakers anyways. And there only £12 =D

Hello, I haven't seen much on Raspbmc on XDa, but its a great little OS. With overclocking controls (much like yuo might get on android) and XBMC booting by default for the professional look =D
Anyway, I haven't been able to get any sound out of the HDMI. I know that sound output can work (on a different OS, like raspbian). Also, i noticed that the HDMI control (ie using TV remote to control it) doesn't work.
Any ideas? Anyone else using PI?
(also, have tried loads of configurations in audio, now i'm stuck)
Edit: I'm trying a clean install, ill post my results.
I've been using raspbmc since I got my first pi and haven't had those problems. However the last iteration of rc5 did have issues with cec which would explain why your remote wouldn't work if your not on the absolute latest. As far as sound only issues I've heard about is with people using external stereo for sound. Disable DTS if your using your tv. With the latest versions be careful with overclocking, there's currently a problem in the build that is causing SD card corruption for a lot of users.

I did overclock it, but i have noticed that when booting up, sometimes i have to restart as it says
Code:
**cant read, cut off screen****al commit I/O error
Humph, im guessing that al is journal (after googling the rest).
Ill report back again on my xbian results, hopefully end of thread? we'll see (i hope my sd card isn't corrupt or something, i dont think so, file management sitll works and it boots...)
Right...
I installed XBian but still have no sound?!
I know that sound has worked on XBMC, i remember when i first got it i tried it breifly, im gonna try with headphone port and see if i get sound. Even if I do, i'd like to use the HDMI output, rather than headphones/portablespeakers.
Any clues?
Edit:
Headphones working fine... i'm not sure whether that is a good thing or a bad thing...
(im testing using a few different sound sources, not just one, os i doubt this is any Program errors. It must be the system. Are there any drivers i can download for a samsung TV?)
Also, i might try on a different TV and see if it's just the tv?!

I see that no one has commented on this in a while, so I hope that the thread is not dead. When I hook up my Raspbmc to my TV through my Denon receiver, I get picture, but no sound. I added the two lines of code to the config file mentioned on the Pi forums that supposedly force HDMI. When I go into audio settings, however, I don't even seem to have an HDMI option. The only options are Analog and Coax.
Thoughts?

I had this problem too when I got a Raspberry Pi a week ago, with a Samsung UN32EH4000 (I don't think the TV has CEC, if that matters). Tried all the recommended solutions, but never had the HDMI choice for the sound even. Went to Xbian and had no problems.
Not posted since forever :S
I have given up on Raspbmc, and even xbian as I have found they don't work well, for me.
I did like Arch linux, but had problems had memory problems.
I have had memory problems on all of the distros tried, I think it might be a hardware problem (after a successful boot or two it forgets how to turn on and just fails)
Oh well :L Gonna try raspbian for a bit and see if i get anywhere.

I was able to fix this by adding "hdmi_force_hotplug=1" and "hdmi_drive=2" to my Config file. I also went pure Raspbmc. You can install XBMC from Raspian, but since my goal was a media extender, I just installed Raspbmc. Wait for everything to settle, turn off the Pi, put the SD card in your PC, open up config.txt, and copy those two lines of code.
Make sure when you edit the config file on a pc, if using windows. Use notepad+ as windows will not properly format the file using utf-8 with standard notepad.

Also... make sure you're using a quality dependable power supply that actually puts out 5V and at least 700mA, I use an Amazon Kindle Fire 2.1A charger just for the headroom.
The easiest way to check is to have the Pi plugged in and on, and check voltage on the board directly with a test meter. If you don't get the correct values, try a different power supply.
Dear All,
I have just flashed to the most update nightly version of cyanogenmod 10.1 for P880, everything seems working fine except for MHL output. It output to my TV with only 720p + weird rotation.. ie even the screen of my P880 is landscape, it display portrait on my TV.
On the stock ROM it won't being that and there was an option to adjust the default output resolution. Is there any way to adjust it on Cyanogenmod??? Please help. Thank you.

The only MHL functionality currently working in CM 10.1 is direct mirroring. This means that it will directly mirror the display on your device as it would look holding it straight up. To add to the fun, the default is to keep your display rotated at 90 degrees when HML is connected, although it is possible to fix this to 0 degrees instead.
Since the 4x screen only supports 720p resolution that implies that you won't get a higher resolution on your TV either using this mirroring functionality.
I have already been trying for weeks now to do something about this, but it's a royal pain. The problem is that the hdmi mirroring seems to be completely handled inside the nvidia tegra proprietary drivers, which are closed source. This means that the easiest solution, which would be to edit these drivers, is not an option. Moreover, it makes it more difficult to establish exactly how the interaction between the android system and these drivers occurs.
LG clearly found a way to make it work though, which I suspect involved adding better multiple screens support to android. That would indeed open up the possibility to change the output resolution, as the tegra chip seems to support higher resolution. I have not given up on the problem yet, so perhaps I'll get lucky in the future and get things working.

Thanks for your detail reply, I have just found that they said about the Nivdia proprietary driver issue. ie. The resolution is almost impossible to fix.
On the stock rom, LG did a very great job on this, even the P880 has only 720P, but they can upscale(or stretch) it to 1080p and rotate it correctly over MHL.
But what do you mean we can fix it by set it to 0 degree?? (I have try the auto rotation and limit it to single orientation, but it does not work) So, how can I do it? Honestly, I really don't care if it is 1080p or not, coz' what I think it is just upscale(or stretch), I can also do it on my TV set too. The problem is the orientation. Anyways, 1000 x thanks on your reply.

I am interested in this MHL problem too
But I noticed that when the device is booting up with MHL adapter in place of course the "cyanogen"(bootscreen) is normal on my TV but later when the rom is fully booted that weird rotation takes place
So I thank that this is CM 10.1 problem, and I dont know how to solve it

I said you can fix the rotation to 0 instead of 90, but that does not fix the problem. You can do this by adding a line 'persist.demo.hdmirotation=portrait' to your build.prop. I do not find it too useful though, as most things you'd want to display externally work better in landscape mode.

After the boot sequence the window managers kick in and decide you should be stuck on landscape mode while connected via MHL. You can change that part quite easily. The real challenge is making the MHL output rotate independently and use the entire screen.

Yes, that's a shame, but it is primarily a vendor problem, as writing proper support is near-impossible when the APIs for the video drivers are kept secret. I also fail to see what your problems with the HTC EVO have to do with the 4X HD, apart from the fact that they both appear to be supported by the CM crew.

Sure.
1) Take your separately bought HML adapter.
2) Plug the power cable into the adapter.
3) Plug the adapter into your phone.
4) Plug a HDMI cable into the other end of the adapter.
5) Plug the HDMI cable into your TV.
6) Set your TV to the correct HDMI output channel if necessary.
Optionally,
7) Discover that HML with CM 10.1 does not work the way you want, since the image on the TV is rotated.
You're welcome.

Hi Wenque
You seem to know stuff about this problem.
I too have an P880 running CM10.1 and I recently bought a new stereo for my car, where I can connect my phone using MHL. And I obviously have the same problem.
Do you know if someone at CM are working on a solution or something? I know you wrote it's hard to fix, but it would be nice with some information on, whether there is hope for a solution or not.
Thanks

The only MHL functionality currently working in CM 10.1 is direct mirroring. This means that it will directly mirror the display on your device as it would look holding it straight up. To add to the fun, the default is to keep your display rotated at 90 degrees when HML is connected, although it is possible to fix this to 0 degrees instead.
Since the 4x screen only supports 720p resolution that implies that you won't get a higher resolution on your TV either using this mirroring functionality.
I have already been trying for weeks now to do something about this, but it's a royal pain. The problem is that the hdmi mirroring seems to be completely handled inside the nvidia tegra proprietary drivers, which are closed source. This means that the easiest solution, which would be to edit these drivers, is not an option. Moreover, it makes it more difficult to establish exactly how the interaction between the android system and these drivers occurs.
LG clearly found a way to make it work though, which I suspect involved adding better multiple screens support to android. That would indeed open up the possibility to change the output resolution, as the tegra chip seems to support higher resolution. I have not given up on the problem yet, so perhaps I'll get lucky in the future and get things working.

Hi Wenque, I have googled around and found the parameter "config_undockedHdmiRotation" on "platform_frameworks_base/blob/master/core/res/res/values/config.xml". Maybe setting it to 270 would solve the issue?
Wondering if it's possible to set the resolution of the device to 1280x720 instead of 720x1280 on kernel can solve the hdmi output problem too..
