I found an app in /system/bin/ that lets you control your displays :-D
Now we just need to figure out the pin-out of the connector If somebody can find me a plug that fit the docking port correctly I could probably figure out the pinout for us and post instructions.
Code:
# nvdmmultidisplay
*******************************************************
dmmultidisplay usage:
dmmultidisplay [disp_option] [case_option] <activity_option>
<disp_option> can be one of the following (default is '--lcd'):
--off: Turn off all displays
--lcd: Test LCD Display
--hdmi: Test HDMI with no display on LCD
--crt: Test CRT Display with no display on LCD
--tvout: Test TV-Out Display with no display on LCD
--lcd_hdmi OR --lcd_crt OR --lcd_tvout: Test for dual display at the same time
<case_option> can be one of the following (default is '--case1'):
--case1: Demonstrate case #1
--case2: Demonstrate case #2
<activity_option> can be one of the following:
--ui: Show only UI without playing video
--play: Play only video without displaying UI
--uiplay: Show UI together with playing video
--file <filename>: Video file to be played (including path)
--query_displays: Query some info about all displays
--query_active: Query more info about active displays
Command-line examples:
Turn on LCD and HDMI displays and play default video; use case 1:
dmmultidisplay --lcd_hdmi --play
Turn on LCD and HDMI displays and play default video and show UI; use case 2:
dmmultidisplay --lcd_hdmi --case2 --uiplay

Does anyone have a SandDisk Sansa device with the connector? I know you can buy breakouts of that connector (like the ipad) from Sparkfun. Maybe that one fits. It is similar to the ipad 30 pin connector
I do. The pins fit perfectly, but it's connector goes to USB. Not sure where to go from here

Wow.. Ok then. I am going to order this. It is a sansa breakout plug that allows you to solder to the board. Once we get it working, we can make a cable with the plug they sell also.
http://www.kineteka.com/sansabreakout.aspx
... and see if we can figure out the pin outs!
Thanks for the update.
YOU ROCK! great find... I just ordered one too....
Does anybody know if it's safe to hook the HDMI directly into the connector? I am worried that the dock might have extra power filtering circuitry or protection we could be bypassing by hooking directly into it. (i have only heard plans for a dock, personally i would rather have an HDMI adapter, it would be AMAZING for presentations, opening up a google docs slideshows work great on this thing already)
Did you try plugging the Sansa USB cable in?
no, i just checked to see if it connected into the port. for gits and shiggles!
Yes, i did plug the USB into my computer. Nothing recognized while G Tab was running 2.04. When i reboot into CWM, i went into mounts and storage, mounted /sdcard. Computer didn't recognize. pulled USB from computer - viewsonic reset. Mounted storage in USB mode - same happened. Nothing showing up on the computer.
I know its not cost effective but wondering if something like this would do anything with the sansa usb connector attached?

Mine is on its way. Tried to find a similar breakout for HDMI, but not found yet. I guess I will just cut the end off a cheap HDMI cable and wire it to the breakout. When we get it right, I will wire it to the regular plug. I bought one of those too.
Now, who is going to figure out the pinouts? I dont have a scope to read signals like these.. just a good multi meter

Hey Mike! Welcome. We need help! no one has an hdmi cable for the viewsonic yet. As you see, someone believes the sansa cable fits our viewsonic dock... I and others have ordered on that chance. But we do not have the pinout on the dock connector...and as I mentioned, we need a pigtail HDMI cable to connect to the sansa breakout. Can you send me a private message and we can work on this.
thanks
Dennis
Ok... got my sansa connector breakout board/connector and a spare connetor. but, I have not a clue what to do next! The breakout board connector comes with the other parts to put around it such as the locking pins and plastic cover, but there is no way that fits over the breakout pc board, it is slotted for a cable like the parts on the regular cable connnetor I got. So I assume it does not work so I am clueless why it is included. That being said, there is very little contact with the connetor and the port on the tablet (absent the locking pins to hold it in). Now the big question is while I have it "sitting in there" (connected) how do we begin to test any signals coming out of the port??
Kinkymonkey,
Did you get your plug yet and have you had any luck with the pin out?
Mike from Kineteka, can you lend any insight on the pinout for us?
Thanks
So,, What can i supply about your development??
I have received your PM. and what information need i supply?

We need the schematic for the connector
Thx
I just got it, but it won't fit the plug, it looks like the metal tabs under the connector are just a little bit closer together then slots on the plug - it fits in sideways but it won't go in straight because of those metal tabs :-( Did it actually fit in yours? (i have one of the first 1000....)
Ya- that black cover in the bag is wierd.. did you notice the big holes in the side too- i think those little tiny plastic clips are meant to cover them- man would that be a pain to put together. it must have come from whatever kit the sansa connector came from, They just bought a bunch of cheap connectors and soldered on the breakout board.
On a plus note, the box also contained a cool rubber ducky robot, a christmas card, and a multipage color sales guide for the archos tablet line (LOL! ironic) so it wasn't a total loss... just a really expensive rubber ducky...
oh, btw wrap a piece of electical tape around the pins coming out the back of the connector (instead of the black plastic cover), that way you don't have to worry about touching them when you are plugging in it (sending static electricity from your fingers into the HDMI connector would probably be a bad thing)
Wrap it from the thick part of the connector back down the pc board coming out the back.
I did that so i could get a better grip - but it still won't fit

I did not get any of those trinkets......but my plug engages but just not very deep. I wa assuming the metal hook piece ( when it would be assembled with the cover and the black plastic " buttons" for squeezing the pins) would hold it in. But the other poster said his plug fit.....so i dont know.
I wish Mike from the vendor would chime in again.
a bit confused
XDA is no longer worth my time.
I am briefly reserecting this old thread as I got my dock today. I was all set to pull it apart, cut the end off an HDMI cable and try and trace the pinout with my Sensa Breakout plugs I bought from Kinetica. Well, after seeing the connector on the dock, and knowing the Kinetica plug did not fit and I was going to have to modify and force it on someway, it is not even close to looking like the plug on the dock. I think the poster who plugged his Sansa cable in must have forced it or something or it is completely different from the cable that Kinetica sold us as a Sensa plug. It looks so much bigger in width and it the throat is much narrower ( I know the dock plug is made for the tablet to just "sit" on it and not stay pugged in, but even though it does not have the little clips on the sides that hold this type of plug engaged, the SAnsa cable is just not going to work. So, I will not be pulling the dock apart at this time until someone can spec the dock connector and find us one that is an exact fit.
I wasted $20 bucks on those two plugs unfortunately along with a few others here.
Hi everyone.
So i tried to replace the cracked screen in a Moto G (I just replaced the display+digitizer+glass module). After the reassembly everything worked except for the digitizer (it worked before when i tested it). I tried to reconnect the digitizer connector (the tiny one which connects the digitizer controller to the display connector ) multiple times, but nothing worked. Has anyone faced a similar problem before?

Hi, I have exactly the same problem.
In my case, it's my second screen, so I've already eliminated the screen+digitizer and the cable connector like the origin of the problem.
Has anyone any idea?
Thanks!
PS: Ening, did you get to solve your issue?
much sad

Bad news. My digitizer cable is damaged. On both original phone and the donor. I was not careful enough: the closer inspection showed it. I am going to order another screen or a donor phone (like a used verizon one or something) and try it again.
So the thing is that the video on etradesupply shows it wrong. You have to unstick the tape covering the digitizer cable connector, then unsnap the clicky thing, and only after that should you unplug the screen master cable (the one that goes into your PCB). Otherwise, it is very easy to damage the touchscreen controller cable (the digitizer one).
I really hope you have a different problem and there is still hope for your phone :crying:

Hi Ening,
How do you check the veracity of the cable connector failure? I think I have the same problem than you, but I haven't a way to check it 100%, because I haven't anyone who can lend other screen to me, and the original screen it's now completely destroyed.
I suppose that I will have to send back the screen to the seller and ask for another.
Thanks anyway!

Hi, i gave the phones to a guy in a repair shop and he looked at it through a magnifying glass
agnobi, I have exactly the same problem, but tested several digitizers and same problem
see my post here : http://forum.xda-developers.com/moto-g/help/black-screen-backlight-ok-screen-t2803431
did you solve your problem ?
Me too
The new digitizer doesn't work and now the 'old' digitizer dosn't work anymore
Everyone has found an solution ?

The flex cable part that connects the controller to the rest of the cable is very thin and easy to damage, you've to be very careful or you're gonna screw it (like the OP did).
ofcourse there is a slight possibility that it came defective, but you should have checked it right when it arrived. So far I haven't seen any incomparable ones, but who knows.....

I think there is something else.
On my side, the 3 digitizers (old one + 2 new) give me same result.
The I think the problem should be on the mainboard or a hardware/software blocking ... or maybe something we didn't re-assemble well
and little question : what is the role of this part (see my photo) ???

Probably the last :>
That thin metal plate makes connections on the back of the PCB (its mounted right between the display and the PCB) and I think it connects to mass.I got no idea what it's role is (prolly its a fitting or some sort of heatspreader).I've assembled one phone without it and it worked just fine, but I've put it back afterwards, just for the sake of being complete
and your digitizer works fine ?
I think also that the issue comes from the connection PCB-patch or as you said software digitizer blocking.
So I 'll try to flash a retail rom to see it .... ...... The digitizer still not working

I've replaced 9 digitizers on 9 different moto g's.None of em had any kind of these problems.This leads me to the conclusion that you've done something wrong.
The worst I had is 1 dead pixel on one of the new displays ( I'm using digitizer+display+frame assembly ).

very interesting your experience ...
the strange thing is that we are several persons to have the same problem and the same symptoms ...:silly:
I've unsnapped the connector as they said in the video of etradesupply...
Maybe I've forgotten something.... you have followed this video ?
Edit :My screens are working except for the digitizer.

I've also reflashed a stock ROM ... no change
so it's not software/firmware related ...
so it's hardware
Never, all worked the first time and afaik they are still working fine.Gotta mention that the ones I`ve used are chinise ones, but look and feel like the original, even the glass feels like gorilla glass 3, altough I don't believe that's the case :>
I have a huge scratch down my screen and the local mobile repairing guy quoted £55 to replace.. I thought this was a bit steep.. I expect him to use real gorrila glass 3 @ that price
Sent from my XT1032 using XDA Free mobile app
finally I've just fix my digitizer
It was 1 or 2 pin twisted on the right so there wasn't a contact between the PCB and the patch....
denseye I think your black screen can be fixed, you may see the pin on the left...." Bon courage " PM me if you have questions....
I've got now my earpiece which crackle but I thinks I'll not try to fix it....
Good night
You mean a pin on the pcb connector where thé LCD câble goes? (Français???)
A pin means a spindle which links the patch(LCD câble) to the PCB.There are many pins which compose thé connector.
(Yeah I'm french and i've sent you a MP.... "Dur dur le correcteur ortho ...")
Hi, I have an Iocean X7 Elite which I have had for almost 8 months now. Recently I cracked the screen ( by accident of course) and I have purchased a new one.
So.... I installed the new lcd screen myself and it works fine. Only problem is it did not come with this black connector sticker/mat that lies behind the battery. So I was unable to connect my mainboard to the speaker, mic and charging socket area of the phone. I did peel the sticker/mat off the old lcd and connect it to the new one, but to no avail it does not work.
I really need help on what this mat is called as I believe this is the issue with the phone. Any help would be appreciated.. Please feel free to ask any questions.
Thank You Very Much
Hey All,
I recently dropped my nexus 5, however there is no screen damage, there is still damage to be noticed. On the screen itself, there are numerous vertical lines, disallowing me from actually using the phone. I've been able to connect a USB OTG mouse and connect to my chromecast which works fine.
Again, the screen itself has to visible physical damage. Could the GPU be broken? I'm really confused.
Here's a link to the damage: http://imgur.com/5weAP2Z

I think you broke the LCD panel (/liquid crystal)l behind the front glass, that's why you don't see any damage on the screen.

Thank you for the response. So would I need to do an entire digitizer + Lcd replacement costing me around $100ish? And would that fix the issue?
Your actual gpu/image processing works since u were able to use it on chromecast.
Since it was a drop there are a number of things that could have gone wrong . In order from cheap to expensive it's flex cable , lcd , motherboard. The fact that you can use screencast , and the lack of touchscreen response could mean the screen is broken and not the mainboard. But again could.
If you could get a temporary replacement screen for test you could diagnose it and see if you keep the screen/buy one or scrap the phone.
Thank you everyone for the responses!
Hi
I'm looking for a way to connect my note 4 to an external vga projector (during a university lecture). Have no idea if it's even possible, but i broke my laptop and the note 4 is my only chance...
It's easy if your protector has wireless, just connect in the same network and use screen mirroring.
Another way is if you protector has HDMI, in this case, use a MHL cable.
Last option, if VGA is you only choice, you'll need the MHL cable plus an HDMI - > VGA converter. Keep away of the very cheap ones that only work with specific hardware, you'll need a real converter.
