Dev Request - HDMI Desktop Out

Ok, I'm getting this "phone". I've been sitting around waiting for a release date for what seems like a year now, lol.
Here is my one request, from the marvelous XDA dev community, who has never ceased to amaze me in the years I've been here.
I want this thing to do HDMI out. I'm not talking pushing a YouTube video out of the HDMI port, I want to see Android on my 24" monitor. I want to be able to use a Bluetooth mouse and keyboard to run the controls, and I want to be able to dock my Streak and use it on a larger display. 720p/1080p would be a huge bonus, but I have no idea what limitations are in place there.
Ok, that's it. Make that happen, and I will be very happy.

If you pay £55 for the Dell Home AV Kit it will do this I believe......

Granted, I don't have a Streak on which to try it out...but isn't that only for videos (YouTube, video files, etc)? As far as I'm aware, you don't get the actual desktop, right?

I don't have one either, but in a video I saw it appeared that the dock only pushes the video through the HDMI and not the android "desktop."
I too would love to be able to do this though!

Ah right thats not too good then, the Samsung Galaxy seems to be TV-Out and just replicated the system as on the screen, I'm thinking of buying a Nokia N900 to play with as it has TV out and would let me play SNES / Mega Drive games etc when I'm in a hotel room.

I wonder if full TV Out is something we could hack

£55 is a lot for just movies out...i was hoping for full android on my big tv

Yeah, that's for sure. Big deal, if I wanna watch just movies, I'll find a computer and do it. The power of HDMI-out is in being able to use Android on your phone on the go, and then docking it and using it as a netbook-replacement when at a desk (or as a HTPC when in the living room, etc.)

Give it a few months once the Chinese get their hands on it and they will churn out the Accessories and flood ebay

I need this also for a bmw idrive integration. I'm sure the community will crack it.

I just bought a BMW with the new 1280 pix CiC I-Drive display. With a Motorola Bionic, I'm hoping to send TV to the phone via SlingBox and send the HDMI out from the phone to the display in the car.
Thoughts?

Something pretty cool that apple will implement into ios 5

I have not tried this, but it appears to do the same thing.
There is also another app called Skifta that is DLNA certified as a streaming app.

It says it has been around since 2009... Apple isn't all that innovative after all, only very good at marketing.

Horrible at marketing, not very good.
From the tv ads I tought it was their renaming of DLNA (laaaaame), but this is incredibly cool and completely different! Aside from that the PS3 had DLNA support in 2007 already, so it's even older even if I'm not sure how much.
DLNA offers you to stream multimedia files (video, pictures, music) to a compatible reciever, but that's all. You wouldn't be able to watch video from an app like Hulu and so on, just files you have on your device. Also, nothing like seeing on a tv (passing through a special device like Apple TV, true) the game/app you are using at the moment, if it was just DLNA. It's closer to a wireless HDMI transmitter/reciever, but it costs way less than that!

Airplay has been around for a while. It is similar to UPNP/DNLA.
Anyway, Airplay is an RTSP variant with DRM. It's been reverse engineered, and there is an a freeware C lib for it. The biggest advantage to Airplay is that it probably had tighter standards. UPNP allows pretty much anything, which means you end up with a lot of cross device format compatibility issues.
I haven't seen a lot of really good uses for either. DNLA is kind of fun to DJ with and maybe should pictures/videos from your phone. I think a really cool app would be to take the SD card from my camera and send the pictures to a TV. You can kind of do this, but I haven't seen anything real slick.
If you have a device that supports AirPlay/DNLA, it likely that it can already do whatever you need to through that device and use your phone/tablet as a remote (This is how I use my Onkyo TX-NR509). The problem is that both protocols rely on a wireless network, which is susceptible to drop outs.
FYI: You should check out iMediaShare. It's pretty impressive (I'm not sure it works on Transformer, it's really geared more toward phones).

How about a cheaper, more efficient, more universal solution transformer owners can already utilize: HDMI mirroring...
WiDi (if it ever becomes standardized) will then blow airplay/DLNA out of the water anyways and only requires a firmware update in existing WiFi modules.

[Q] Will miracast in 4.2 work on my old N7?

As announced, JB 4.2 will support miracast which allows display mirroring through wifi-direct. I don´t understand whether this feature require certain hardware, and my question is wheter this will work on my 16 GB Nexus 7 when it is updated to 4.2? Anyone know?

Tegra 3 supports it and it uses wifi direct so I'm confident it will be supported.
Sent from my XT910 using Tapatalk 2

I hope that's true. All the hardware indicates it is able to support it, but not necessarily that it will actually be made available. The Nexus 10 doesn't have the option for Miracast, despite having WiFi direct/Android 4.2.

I don't get what all the worry about will it support it. The only hardware thing necessary is does the device have hardware encoding, and this does. Yes the N7 has wifi direct but ANY device could be upgraded to support wifi direct. It's not like wifi direct is some additional hardware on a wifi chip. Any wifi could technically support wifi direct.
So I would be really surprised if this doesn't support miracast. From what I've read the hardware encoder has a big influence on latency (as does the cpu). So one question that I would like answered is, how low is the latency? Movies/browsing etc doesn't really matter, but for gaming.
Has any article mentioned how low the latency is with miracast? This will vary from device to device of course, but even knowing for one device might give a ballpark of what to expect with the n7

I can't believe miracast is not supported by the N10! Mind boggling...
Sent from my SAMSUNG-SGH-I727 using xda premium

yes I just read that. Does it not have hardware encoding? The nexus 4 definitely has miracast enabled but not the nexus 10?!

Where is written that N10 doesn't support Miracast? I watched android developers hangout on YouTube a few days ago and if I remember correctly then they told both N4 and N10 support it. When someone asked about N7 they first told no, but then said they don't know for sure. Unfortunately YouTube is down, so I can't double check that at the moment.

Here:
Miracast is the Wi-Fi Alliance's standard for wireless streaming of video, and its addition to Jelly Bean made us very excited -- Android finally has a response to AirPlay. Imagine our disappointment, then, upon learning that Miracast isn't supported in the Nexus 10, at least not yet. It is there in the Nexus 4, a perplexing state of affairs that Google wasn't able to give us much clarity on, but it does appear that this is not a hardware limitation, since all the communication takes place over WiFi. If Miracast isn't going to be software-enabled in every Android 4.2 device then we're struggling to see how it's actually part of the OS, and we're definitely feeling let down about its potential to improve the platform as a whole.

It's not like the nexus 10 ships with 4.1.2. It comes with 4.2 but yet miracast is disabled?! But he's wrong about pointing out wifi as the potential hardware limitation. Everything has wifi (and could potentially support wifi direct as that is done in software) the hardware barrier is hardware encoding. Does anyone know the details of the chipset the nexus 10 has?

Interesting... Cnet review says it is supported, but they didn't have a dongle to test it.
I believe even the Verge/Google video said it is supported, but again, I can't check that either at the moment. Why is YouTube down when you need it the most?
Does anyone know if Miracast supports audio only? I know that it supports audio and video, but what happens if I want to connect it to my AV receiver and use it for audio only?
Edit: YouTube works again. http://www.youtube.com/watch?v=Z92fwFQntG8 at 56:30 they say that both devices have HDMI and Miracast.
I think the software in review devices wasn't final. Some N10 review devices didn't have user accounts either, but the final software clearly will have that, so I believe its the same case with Miracast.

Does anyone know if Miracast supports audio only? I know that it supports audio and video, but what happens if I want to connect it to my AV receiver and use it for audio only?
Turn off your display and you have audio only

That's what I want to do, but is it possible? Does the Netgear ptv3000 work if it's not connected to TV?
It is possible that it doesn't allow connections from android device if its not connected to TV. For example Nexus Q doesn't allow streaming YouTube to it if its not connected to TV.

I'm thinking it should bypass through the a/v receiver but I am simply speculating... it's going to be one of those things we will have to test with or a/v systems
Sent from my SAMSUNG-SGH-I727 using xda premium

I would buy and test it but I can't I can't find this product in any shop in Europe. And US shops that have it in stock don't ship to Europe.

I'm in the u.s. and I will buy it once the 4.2 update and miracast are official for the N7. Then, I will report back with my findings on how the netgear miracast box interacts with my a/v receiver.
I'm so pumped for this feature!
Sent from my Nexus 7 using xda premium

I never thought about audio only. One thing I hope is possible is to turn off the n7's screen but still stream. It's one thing if you are interacting with it, but say you are streaming a movie, why have the n7's screen on for 2 hrs? Or even a game where you are using a gamepad and you aren't touching the device at all.
I've wondered if that functionality is in the spec, but I doubt. The other thing I wonder about is how low the latency is for gaming.

I found a US store that has it in stock and ships internationally. Only bad news is that shipping costs more then the device :| I'm not sure I want to pay that much for it.
About games, I have no idea if the screen can be off when streaming, but I hope so. One interesting thing that was discussed in Google developers hangout was a api that let's app developers use the two screens (tablet and connected display) as separate displays. For example the game runs on TV while your android device has buttons or whatever else on display.

HDMI issues real? (about to buy)

First of all, I've read the prior threads, but my question is contextual, so please bear with me.
I currently have an Acer 500 which I use for web, email, RSS on a daily basis. On trips the HDMI-out is a lifesaver in the evening at the hotel, as anyone with kids will attest to.
In the spirit of Father's Day the Boss has authorized an upgrade, handing the A500 down to my kids for homework use.
I understand there are 2 HDMI issues with the N10:
- Scaling
(fixed in Videos and MXPlayer, and possibly with newly discovered code/app)
- Compatibility
no sound via HDMI
no video with certain TVs
I don't care about scaling, and can live with letterboxed video.
Just how bad are the TV compatibility issues, really? I know HDCP can wreak havoc between devices, but both the Acer and SGIII have worked well with every TV I've tried them with; I have decent cables/adapters. Is the problem a connector issue, or is there an inherent issue with the N10 HDMI pathway hardware? If' it's just the plug, I can return it until I get one that works. If it's the intrinsic hardware, this would be a show stopper for me.
Again, I know the prior threads on this issue, but I'm trying to gauge if this is an unfixable issue for most people.
TIA.

From what I've heard and seen, compatibility with older Panasonic-based TV's (VIERA for example) might be somewhat bad. The VIERA TV I have has working video, but no audio. Some no-name HDMI TV my friend has (can't think of the actual name) works fine for both video and audio.
Not sure if there's any general rule or anything that determines compatibility though, or how other devices handle TV's...

HDMI with video and audio work perfectly fine to most things, the problem is not that HDMI simply doesnt work but rather that certain companies do not conform to all standards properly and this causes compatibility issues. As Espionage said, Panasonic's are the big one with no audio, and Sony Bravia's also tend to have issues. I use my Nexus 10 to go into my Onkyo receiver which then passes video on to my Panasonic plasma and audio goes to my speakers. It works perfect except for the obvious scaling issue because it is not trying to send a 1080p signal. That is easy enough to live with or you can do the workaround to make it perfect if you really care that much.
The thing that sucks though is just that hotels have all sorts of TV brands, so compatibility will just be hit and miss depending on which models of TV they choose to have.

Most of the time , hdmi doesnt have sound .
Many incompatibility tv s .
I personally have a pan 30gt ... No sound .

When you say that the video is fixed in MXPlayer, where did you see/read this? I would be interested to know because I heard it was coming but for me the scaling is not yet fixed.

and what is the price ? im looking for something in good price i found some from connection lab and try to find out if its really good

Guys, Can anyone confirm if Nexus 10 needs to charging for the HDMI out to work? My nexus 10 doesn't output via HDMI if its not connected to power.

I get no sound through my Viera too, it's pretty damn annoying actually. Regardless of their HDMI 'compatibility restrictions' or whatever, all other devices work correctly with it including my Galaxy S3 and a whole assortment of cameras, PC's and gaming consoles. Hoping for a fix in 4.3.

connectionlab is good!
So far so good. Couple of days ago I asked you about connectionlab brand, but since I have no responses I thought I'll give a chance and bought ConnectionLAB HDC-10 Premium 10m HDMI CABLE. Is beautiful!
I have to say that I'm really pleased with my new baby. Seriously, you get a good quality for a good price. My friend bought a cheap hdmi cable and sait it broke down into 2 after 15 minutes! But this one from connectionlab seems like a good choice

We need OUYA as Miracast Receiver (someone did it on Nexus 7?!?)

Saw this on Reddit:
http://www.reddit.com/r/Android/comments/1iwnvb/miracast_working_on_nexus_7_devices_link_to_dev/
http://www.youtube.com/watch?v=WMlTxTyoaOs
I was only mildly interested until I saw the note that he got it working both for receiving and sending.
If we can integrate this into our OUYAs (and it should be easier to do since Nexus 7 is somewhat similar hardware), then we won't need another box to receive Miracast streams!
I will try and port it, but not sure when I'll get around to it. Posting it here in case some dev wants to take a crack at it sooner!
Also if anyone can verify that this will/will not work, please do! Getting the OUYA to receive screen-mirroring of some sort has been on my wishlist since I first ordered it.
EDIT: Knew there had to be a catch I wasn't thinking of... The Miracast stuff linked is working with Android 4.2, whereas OUYA is 4.1, so that would probably be the main hurdle -either getting OUYA up to 4.2 or backporting Miracast+patches to 4.1. Not sure how difficult either would be.
EDIT2: OUYA's weak wifi would probably also be a problem, would probably work better to rework the streaming to work as long as you're on the same router.

What about the Chromecast device? I'm really not understanding the goal here.
Basically sending video from a device, to the Ouya, to pass through to the TV?

Yes it's all about mirroring the screen output of your phone via ouya to the TV. What's the point? Mostly displaying content without having to transfer it to the ouya.
Oh and chromecast doesn't support miracast.

Yeah, I posted all this before I heard about Chromecast.... believe me, I jumped on that boat quickly!
I already got my Netflix promo code and my chromecast should arrive by Wednesday and I have great hopes for it, but yeah, it won't do full-on mirroring. True mirroring isn't really needed in most use cases though, but it is handy in a few.

If Chromecast could do full on mirroring we woudn´t even need a Ouya anymore.

At first this didn't make sense to me, ouya as a miracast receiver to stream from your nexus 7 while the ouya is already hooked up to the tv via hdmi?! But when I think about it, this could make the ouya perform double-duty as a small miracast dongle/receiver. I was looking to buy a miracast receiver but if the ouya could do this, then I would probably buy this as my miracast receiver to boot. I guess if you had a video or somethng on your nexus 7 and didn't want to bother sending the file over to your ouya, you could just miracast it.
Personally, I think if the hardware is capable of it, why not? meaning why isn't miracast enabled in all devices by now? Last year they were saying the n7 (and the n10) couldn't do miracast, well this guy proved it can, and the n10 officially has support as of 4.3.
But here's the bad news: I was reading that guys blog who made miracast work for the n7 and the sink mode (acting as a receiver) has been stripped out of android 4.3. Why google did that I don't know.
I commented on it here:
http://forum.xda-developers.com/showpost.php?p=44124359&postcount=7
His site mentioning it is here:
https://github.com/kensuke/How-to-Miracast-on-AOSP/wiki/Android-4.3
I'm still surprised so much time has past and none of the rom devs were trying to implement miracast in their roms for the n7.
I hope the source from 4.2.2 (last source with sink code) can be brought forward to 4.3, but that probably makes this all the harder. But I'd be interested to hear why google removed that functionality.
it's also a neat feature to be able to miracast device to device, for say showing someone how to do something, share a video etc. I guess google never advertised the n4 as capable of being a receiver?

You need to research miracast more. it's a failure, there is a delay which makes trying to play a game useless. unless your playing checkers or watching a movie. Miracast is useless , it's why devs don't bother with it. Chromecast uses a google tv port to do the heavy lifting. get a Bluetooth mouse and keyboard and a Bluetooth controller. link them to your nexus 7 (2013) with hdmi out and you have a ouya on steroids.

Hmm, well this video with the work being done for nexus 7 looks pretty smooth. Yes, a little latency, but for a 3d game that's working pretty good. Especially on a n7 which supposedly couldn't do it.
I read one comment on it being a failure but I couldn't find any comments on any dev here attempting to implement it in their rom. Maybe there are some things to work out, but it's still getting a big push. LG has announced about 70 tv sets with built-in miracast and mircosoft has it in windows 8.1. So I wouldn't give up on it yet.
