Just curious if anyone knows if the touch-display functionality on the atrix will work with HDMI mirroring when connected to a touch-sensitive external display?
Curious as I'm contemplating getting one to setup in my car in the center console, idea is to replace a display in my center console with a touch-sensitive one and run 1x HDMI & 1x USB cable into my arm rest storage area where the phone can reside.
Would be nice if it worked, I could have android on a larger display in the car, internet, navigation .. etc etc... seen guys do this with some tablets but I'd like to see if I could run it off the Atrix.. could even wire the audio to an 'Aux Input' on the back of my radio and use the phone to play music on my car's system.
Similar idea to the padfone concept, just different application.
Just don't know if the touch-screen functionality is native when its connected over HDMI or not, anyone ever messed with it?
I suppose with webtop it may be possible, especially if you have ubuntu or debian, as for hdmi mirroring I wouldn't think so... and if there were calibration software you wouldn't be able to run it on android... So I would say you could try and that it is theoretically possible. Though I don't have a touchscreen to test it with...

What would be involved?
I have a 6800 with a bad screen. I also have a couple of spare touch screens(5"). One from a GPS and one on my car stereo. How hard would it be to find the correct wires in the phone hard wire one of the other touch screens. I know the driver might be hard to find to get this working. But heck I am just playing with this. I would kind of like to connect the computer part of the phone to a car EEC. I have found the software to run on the PPC. Now I just need to connect the aux monitor and install the drivers.
I would really like to get it set up as an aux input to my indash monitor.
Give up it isn't going to work to use a different touchscreen
ebay...you can have the touch screen only for 20$ and the complete touchscreen and the screen for around 40$

What is the software you have, do you have a link to it?
Can you upload it? (Is it free?).
It sounds real cool to de able to monitor the EEC function, Maybe "adjust" it too.
Any way, I think even the old 6700 screen won't work on my 6800.
But let me know about that software if you can.
Thanks.
Would something like this work for you?
http://www.wmexperts.com/review-htc-tv-out-act100-cable
Are there retail component cables available for TV out on an HTC device? If there aren't, is there a work around/DIY solution?VGA/S-Video/possibly HDMI....ANY ideas/ contributions are appreciated!
Seems to me it is a software issue and a cable one. The device can only put out NTSC/PAL. Composite video only requires one wire. Component would need 3. Where would the extra pins come from (in the USB connector)?
Wouldnt higher quality S-video still be possible though?
Not sure if this will work for you guys, but I used the multi-adapter that came with my Touch Pro2 and a 3.5mm jack to composite cable to get TV out from my TP2. Basically, it was a cable that came with my camcorder. I had to remove/cut the blue wire inside the multi-adapter to get it to work. It works automatically without additional software. I found the information from another poster at PPCGeeks.com. I would have provided a link, but since I'm a noob, this site would not allow me. Good luck. Hope this information helps.

Thanks for your response and yes this does work as I have been using this solution for about two months now and it's "okay" at best...I am still looking for something that would enable at least a "clean" 480p picture with every pixel cleanly represented without all the noise of the composite cables....
I am planning on getting a tv out cable from the following website as soon as my TP2 arrives (hopefully on tuesday):
http://shop.lab88.co.za/pL88OL-61/HTC-TV-Out-for-Pro--Pro-2.aspx
The cable sells for R188.00 approx. $25.00
They are the official importers of HTC devices in my country and their prices are very reasonable.
try sparkfun.com and search for 'extusb'. if you are feeling adventurous like me then go for the cheap one (style 1) otherwise go for the one with the breakout board. either way, its good fun but be prepared for anything. you should have a bit of knowledge on how to solder though. tried it myself and it worked but with all the bare wires hanging out of the video cable it's in a box somewhere in the garage, lol.
sorry about my lack of using the shift key, hehe

I'm not sure if that is possible since the output of the device is not digital. And even with a USB to composite cable, the data will still be in analog. Good luck with your search and please provide an update if you find anything. Thanks.
Im thinking "S-Video" would be achievable, no? Anyone have thoughts?
If you google for "composite-to-s-video" you get lots of little adapters for under $10, so it can obviously be done, but I doubt the video quality can improve. You also see decoders that cost $150.
If you look at the product description here
http://www.amazon.com/Dayton-SVC2-Jack-S-Video-Converter/dp/B0002KR7G8
it actually says the quality won't be better than the original composite.
It's a huge sight, but it is a better question to research over here:
http://www.avsforum.com/avs-vb/
I think component PAL output is created through hardware, as running video at the absolute highest quality without dropping frames still runs perfect(on the phone) when i click in the video output. if this was done in software then it would slow down the video.(tested with fast moving scenes at really high h264 bitrates in full res so it would be noticable)
The only way i can see it working is if you "somehow" send the screen output over a normal usb connection to an external device which then created the composit output. This would have to be done in software which would be slow and inefficent if it would even be possible at all. If your trying to say... play video at a higher quality then PAL along with software running in the background outputting to said device... well yeah it just wont happen.
What exactly are u trying to do? if its something other then video like presentation u might be able to set up a webserver on the phone(pretty sure there is already software to do this) and take screenshots(software to do this too) and generate webpages in a higher quality that u can see on a computer ect that can plug into a TV

hi!
I just ordered an asus eee tab transformer for my car, as car entertainment system and navigation system. I am planing to invest some time o modify the hardware of the car to fit the tab optimately in.
One thing I'd like to do is to let the car command the tab for boot and shutdown. I am thinking of using the asus docking station interface of the tab but I have no pinout of this connector at the moment. Can anybody help here?
Maybe it is also possible to throw typical "next", "back", "play", "stop", ... commands? I am expecting an serial interface or something similar. Since I am an routined embedded developer, with a pinout this should be no problem.
The second thing is maybe a software thing.
I have an bluetooth car radio which supports one connection at the same time. The Idea was to use the Tab with bluetooth a2dp but with this connection all calls on my bluetooth phone are ignored. Is there something to establish a android to android bluetooth connection where the tap plays the roll of a bluetooth a2dp headset.
So for music and navigation:
Tab <-> CarRadio
For phone calls:
Phone <-> Tab <-> CarRadio
The other thing is, can the android tablet keep 2 bluetooth connections at the same time from the hardware point of view?
Ok, I think I wrote enough for now ^^
Hope somebody can help with any information.

maybe someone has a good link to the asus support?
oops, sorry

Something to consider when designing.
Not sure if this is going to be a permanent install or not. But you can easily set up your audio through the Hdmi instead of burning battery with your Bluetooth. At least you can still use your phone through the Bluetooth. You can also incorporate other monitors in other parts of the car. I was speaking to a car audio shop for this type of install myself a few weeks ago. I will try to get more details and report back. Was waiting for the desktop docking station to come out to really run with it.

Bluetooth battery burn would be no problem since I want to load the battery over the car. Anyway... I'm afraid that there won't be something like a "bluetooth router" so I have to use the analog audio out. That brings me to my first question: I need the pinout of the asus connector to control the tab over the steering wheel control.
I don't think anyone's figured out a pinout yet, and even if they do, it wont be as simple as "this contact is for play, this one is for skip, etc". All those most likely go through a usb interface. Not that that would be impossible, but if you're using bluetooth your headunit should support AVRCP for sending those commands over bluetooth. Most android devices only support 1.0 right now, but that still gives you play/pause, stop, next, previous, maybe ff and rewind too.
As an embedded developer here follows one idea that maybe can help you.
Why not using all via BT, I will say you prob looking for some BT support inside the kernel. If you find a similar application using linux (google it), maybe you can ported it to the transformer. Compiling the kernel with new drivers is very easy, then u just need to get into the software part.
Have fun.

I was thinking about a similar idea. Bluetooth could be an alternative but with bluetooth it won't be possible to switch the device on. So I tried to find a pinout and maybe I have luck to command a power on. Anyway... Right now BT seems the more realistic way, you're right.

Android and the TF already support A2DP audio streaming and AVRCP remote control over bluetooth, there's nothing that needs to be done here. I'm pretty sure its only AVRCP 1.0 though, which only supports the basic controls (play, pause, stop, next, previous, etc). The newer versions also do things like metadata, so you can see on your headunit what song is playing.
I can say from experience that working with improving BT support in android is not easy after I spent a fair amount of time banging my head against the wall trying to add MAP support to CM7. In any case, without HC source it would be impossible to do here anyway.

I'd bet that there's no way to power it up over the dock connector since the keyboard dock doesn't support it.

Power it up maybe not, but wake it up certainly. If you allow the unit to be in deep sleep when you open the dock it wakes the unit. And as long as you are constantly feeding a small amount of power to it to keep it fully charged it shouldn't be a big deal. Maybe tear down a dock to provide an extra battery to the unit and perhaps the circuitry you need for wake on start of the car. I don't play with hardware so not sure what this would do but it seems it should be possible since it already does this to an extent.

Im Not sure hat this "deep sleep" is. is this the same like when i press the power button shortly on the tab or another power mode?
I have no dock and I wanted to save my money and not buy it.
Gents I bought a generic POWERED MHL cable and when I plug it into the S2 WiFi won't connect anymore to my network. What gives? I have googled a bit and seen a few issues regarding it, not sure if more have had the issue. I wonder if this is a software or hardware issue. I have 4 days to return this phone if it is a hardware issue.
Anyone else have the same issue? TV signal shows up fine.
In general section someone has this same problem. I believe they said it was a tethering issue so you might have to root
yup i saw that and posted. i called samsung. according to them when plugging in an MHL adapter it disables wifi (even though you may still see the wifi icon) so that it doesnt cause jerkiness of ur picture
Hmm... I'll need to retry. I know cell data worked fine. Will try wifi-only.
Did you get it figured out? I ordered up one last week and should have it tomorrow. I was looking forward to being able to stream netflix.
What I would like to know before I spend the money on the official Samsung one if it would do the same thing.

Wifi works fine with my MHL adapter connected. There is a small overscan issue but nothing I can't work with (my screen is 1:1 ratio so it's the adapter or the phone output). Both the laptop and the phone reported the same external ip.
Using this MHL adapter - http://www.newegg.com/Product/Product.aspx?Item=9SIA07R0608256
P.S. - I just checked (10/29 - 5pm EST) and it did 1080i output. Not 1080p like some suggest but it may not do that until an actual 1080p video is played. Mine was 1280x960 resolution. There were two other interesting observations made that I thought were good when the MHL adapter was connected.
(Inline edits below)
(Clarification: Below observations are during video playback using the Video app only!)
1) During video playback TV does output 1:1 resolution (no overscan issue)
2) TV doesn't mirror phone display. Just renders playback so you can use the phone like a remote.
3) Screen doesn't turn off automatically during TV out playback.
Now then the above are for the video app and just to put minds at ease here are for everywhere else.
1) Screen may overscan but it may be resolution or screen ration differences between phone and tv. Mine is 1920x1080 native.
2) The TV will mirror the phone display so you can play your games and what not on the TV (like in the youtube videos showing off the adapters)
(End Inline Edits)
Now then samsung's claim about studdering during MHL TV out? That sounds like bs. I checked cpu usage during the mkv decoding work and it was at 25% at the highest point and that was done by the mediaserver process. The tvoutserver used less than 2% cpu time to do it's work. I connected via adb over wireless which would of been only possible if wifi was working.

I was specifically referring to the video app that's included on the phone (the samsung one). It mirrored the display everywhere else including in games so everything that showed on the phone showed on the TV.

I didn't know that. Thats pretty sweet. You can plug the phone in, set it down and control everything with the tv remote? How does that work if you have to touch the screen to select stuff. That would be worth the extra cash for the samsung one over the cheap ones.

You can use navigation keys from the TV remote to navigate through the phone home pages and program list and select apps with the "Select" button on the remote, but it is impossible to select apps from the dock. It's not as fast as the touch screen , but it is manageable. My Sony TV is two years old, but works well with the Samsung MHL adapter. I borrowed one from my coworker to try, now I'm looking for a good online deal.

That was stock, so I rooted the phone to disable any tethering app, and wifi is still disabled....did you have to do anything to get this to work?
This is really strange....maybe I should return the monoprice one and get the newegg one.

This may be such an unusual use case that it hasn't been an issue for anyone other than me, but here's to hoping for a solution...
I've just bought a new car (2015 Honda Fit) which has a decent size LCD panel in the dash (but I opted not to get the expensive navigation system) and which also has full bluetooth integration and, surprisingly, an HDMI port for the screen. HDMI is one of the "source" settings, and Bluetooth is a separate one.
I've paired my Nexus 5 to the car in order to take and make phone calls and get the other integration features such as music and podcast playback over the car's audio. I had this idea that if I were to run the Nexus 5 through the large screen using HDMI (via a Slimport adapter), I can have a much nicer Google Maps based navigation system that would give something close enough to the experience of the in-dash nav system minus the touchscreen -- which is fine, as I can set the route, put the phone in a cupholder, and not bother with it again.
Now, here's the fatal snag. While the phone is paired to bluetooth, it insists on sending 100% of its audio through Bluetooth and doesn't send it through HDMI. The car is either-or on the sources. If it's on HDMI, it only plays back HDMI. The screen displays exactly as I hoped -- but no audio at all (again, it's going to Bluetooth). Now, I can switch over to Bluetooth and hear the sound but not get the display. I could kill the pairing to get both through HDMI, but now I lose the ability to receive calls over bluetooth with the handy steering wheel call answering and all of the amenities associated with that.
I'm wondering if there is some kind of workaround -- Android configuration that I've somehow never noticed, or a third party app -- which will allow the Nexus 5 to remain paired and actively Bluetooth connected while still sending audio through the HDMI port (Slimport). I don't see that this would as likely be a car-side solution.
The Nexus 5 is rooted stock 4.3.3.
Thank you in advance for help toward a solution.

I could kill the pairing to get both through HDMI, but now I lose the ability to receive calls over bluetooth with the handy steering wheel call answering and all of the amenities associated with that.
I'm wondering if there is some kind of workaround -- Android configuration that I've somehow never noticed, or a third party app -- which will allow the Nexus 5 to remain paired and actively Bluetooth connected while still sending audio through the HDMI port (Slimport). I don't see that this would as likely be a car-side solution.
The Nexus 5 is rooted stock 4.3.3.
Thank you in advance for help toward a solution.

I can't help ith your situation, but I'm wondering if you can help with mine. I also just bought the 2015 Honda Fit. What I want to be able to do is mirror my Galaxy S4 to the screen for navigation purposes. But from what I understand, it will only work in Park. I don't have the cable yet and did't want to buy it unless I knew it would work.
For a quick test, I plugged a roku stick in the HDMI port. As expected, it worked fine until I put the car in gear. Then the display gets disabled. Does this happen with phone mirroring? Would I be able to actually use google maps and see it while in motion or will the screen shut off? What does and doesnt work with mirroring?

This behavior of the HDMI port / display actually became a far bigger problem than how to route the sound. I had been doing all of my testing with the car sitting in the garage, and because I wasn't ever able to get the sound to do what I needed, I didn't bother to go drive around with HDMI display enabled. I confirmed through this and consulting the manual that for "safety reasons" they have entirely disabled the HDMI input while the car is not in park. Unfortunately, I'd guess this is coded in the system's firmware which most of us aren't going to have a way to tamper with, so this is a fatal problem for what we're both looking to do. I was confident that there was probably some sort of solution to making audio go over both channels, but that's irrelevant in light of this problem.
So to summarize, I'll suggest not bothering with the Slimport (or the other kind of interface, if that's what your phone uses) because it will certainly be utterly useless for this and I don't foresee a solution. It looks like this thread is therefore dead. Thank you for bringing this to my attention, though -- I'd have continued working toward an audio solution and then discovered this bigger problem once I solved that one. You just saved me from wasting a lot of time.

One more thought (stating the obvious, I suppose) -- We've been hamstrung by the assumption that everyone is going to be using the display to watch movies while driving, even though we have excellent reasons which would actually make it safer (an easier to see navigation display). I guess Honda is mitigating lawsuits from the would-be idiots who might actually be watching American Idol episodes while driving to work.
