Hello everybody!
I an an Android app developer and I would like to attach my Galaxy Nexus to a projector (with VGA input unfortunately) in order to present my applications to other people when they are many. In this case I don't want to just start a presentation or show images, but I want the projector to reproduce what the screen is actually showing.
Is this possible? If yes, how?
I've seen that in USA it is possible to buy a micro-usb to VGA adapter that works with Galaxy Nexus, but it is not clear to me whether I'm able to see the screen or only media files. I think that a special app is needed to show the screen, do anyone know which one?
I would look at getting a projector with an HDMI, that way you can hook up and HDMI and I am not 100% sure, may want to search online, but I believe it has mirror mode doesn't it!

VGA is analog and HDMI is digital, to convert between one another you'll need to find a unit that looks like a small box and requires power. Don't be fooled by cables that have HDMI on one end and VGA on the other, these are for desktops that support sending VGA over HDMI which isn't common.
Assuming it has no HDMI port, does it have a DVI port. DVI is just the digital video carrier of HDMI so a cheap pin converter cable will work.

Has anyone tried to use the malata dock with an HDMI to VGA cable?
The dock works fine outputting to an HDMI TV, but I've tried to use an HDMI to VGA cable and I don't get an output on a monitor. Ideally I want to use this on a VGA projector, anyone had any sucess with this...?
BTW, big hand to itsteve for being such a good sport and organising the import and sale of these for us!
Funny you should ask.
My fiance is a teacher and the projectors at her school have VGA ports. Most of what i saw on the web were Displayport to vga, $100+, Bulky, Needed external PS, or had poor reviews.
I found a HP adapter that actually worked, and didnt have any of the negatives i mentioned.
HP NP031AA#ABA $40 right from HP. (I would link, but I am to new (under 8 posts), and it wont let me)
It arrived yesterday. Plugged it in to the dock, and into my vga cable, booted up and it simply worked!
Hope this helps.
Fantastic, thanks! I'll order one and give it a try. Thanks again.
I don't understand. Shouldn't the following work?

No, I don't think it will. I don't think you can transfer from a digital to an analog signal without some type of converter device. That's what the HP probably does.
I've tried the cable on it's own and I don't get any output (I thought it would work but alas not). I guess you do need to have some form of D2A conversion, not sure what the cable actually does do though as clearlky there is an HDMI and VGA connector on it...!
looking for clarification on the HP HDMI ->VGA converter w/G-tab in Malata zpad doc for use with projector? works? or no works?
HDMI to vga , adapter or cable.

To make a long story short, HDMI is digital and VGA is analogue.
Straight through cables (like the ones linked above) will only work if :
- the GTab can send analogue HDMI (very less likely).
- your projector can accept digital signal via VGA input (very less likely).
The cable above would work in rare scenarios where devices are already able to send the proper signal.
In 99% of the other scenarios you will need an extra hardware (converter) to convert the digital HDMI output of the dock to analogue VGA input of the projector.
These devices aren't that pricey (yet not that cheap) plenty of options on ebay ($40 shipped worldwide).
Hope that answers your question ..
Is there a way to connect my 5 year old Dell VGA PC monitor to my Atrix?
Couple adapters, hdmi to dvi, dvi to vga, I'm not sure if they make hdmi to vga.

First of you got to understand that VGA is an analog signal(the wave signal) and HDMI is digital. There is no simple way this can be done. Because you have to change from digital to analog you are most likely need to purchase a converter box of some sort.
There is another thread with the same question.

I'm also interested to connect Atrix with projector. Anyone tried converters?
Hi guys,
I ve got a HDMI adaptor and cable for my S2 and it is working fine on the TV with HDMI, just wondering if I can connect S2 to the telly without HDMI socket?
There is no cable for that. Or use an HDMI cable with a DVI converter on top of it?
Google for HDMI to composite. There's loads of cheap leads to do this.

I am also trying to find how to cheaply connect S2 to a crt tv with either scart or composite RCA - does't look possible without high cost below taken from a web site but not allowed to post link as I'm a new user!:
HDMI To Composite Cable is sought by many people nowadays. People who have old technology equipments try to connect them with brand new HDMI-ready devices. Most old devices are using either composite cable, analog cable, or S-Video cable.
HDMI To Composite CableSome people think that they are able to convert the digital signal from HDMI end to several analog signals in the other end. The truth is, while you clearly can connect wire-to-wire, which simply won’t work. There is no possible solution to convert digital to analog signal without using a converter box. When you see HDMI To Composite Cable sellers claim to be able to convert the digital to analog signal directly without a converter box, they mostly scam and don’t work.
So, is it possible to convert the digital signal to analog signal? The answer is yes, but you can’t use a simple HDMI To Composite Cable. You need a converter box. It will do the conversion from digital to analog without a breeze. You may find them on the market labeled as HDMI To Composite Converter, HDMI To S-Video Converter, HDMI To 3 RCA Converter, HDMI To 5 RCA Converter, HDMI To Composite 3 RCA / S-Video Converter Adapter, but simply not as HDMI To Composite Cable only.
hdmi uses digital signal, so you can use a DVI adaptor but that's it.. (or digital component but that's ultra rare)
to use analogue (scart, composite, component, s-video) you'll need a digital-to-analogue converter box and they cost around £30 from ebay.. you're better off putting that money towards a new LCD with hdmi
Really two questions:
1. Is there a way to adjust resolution or over/underscan on the HDMI output of the tablet? When I have the tablet connected to my TV, there is about 1-2" of black border around the mirrored image.
2. I am trying to output to a LCD Monitor, mHDMI>HDMI adapter to HDMI>DVI cable connected to my Monitor, but the Monitor does display any image - not even a "out of display range" error. The monitor will briefly turn on, then dispaly "no signal." Both adapter and cable work independently of each other when attached to my TV. Is this a problem with the tablet, cable configuration, or my monitor?
Is there anything I can do to check/adjust the signal out from the Tablet? I am using the OG Samsung Dock w/HDMI out. Please let me know if I can provide any additional information.
[Edit] Currently running Tasks 14 Full Rom with Pershoot's latest kernel. And I have the WiFi only version.
same issue
I have a samsung galaxy 10.1 tab in the office and I am trying to do HDMI mirroring. I do not have a dock but I have HDTV Adapter. I do not have a HDMI monitor at office. So, I used a HDMI to DVI converter. When connected, nothing happens. no errors on the monitor just like you said.
So, does it require a TV/Monitor which has a HDMI input?
Or does it simply require a media dock?
[Edit] Does HDMI mirroring requires rooting?
Any help is appreciated.
Thanks
I would assume HDMI mirroring is built-in, as they sell addons for HDMI output. Semi glad to see someone else has the problem... but now its two of us with the same problem lol. Later this week I'm going to try an ICS build, see if there is any difference.

Well, I was glad I was not the only one with this problem
I did some Googling, search Android HDMI to VGA. Should turn up some links exposing the issue. Basically, android cannot natively do VGA. Need a HDMI to VGA converter, possibly powered, but there isn't much information. Dealextreme sells one for $38... and it may not work.
Sucks, seems like a decades old standard would be something engineers would think to maintain compatibility with.

give up
At this point of time, I am giving up and tell my boss to buy a new tablet. This is my office one.
I have Coby Kyros - bought it for cheapness. Will try rooting that.
mHDMI Connected to HDMI>DVI Cable = No Output on Monitor?
I have exactly the same problem with my XOOM and my Samsung T220 DVI-D monitor
I note that noboby has actually answered the questions posed by the previous posters.
Is that because no one knows??
The HDMI and the DVI-D signals are both fully digital and according to info I read on the web are pretty compatible.
I have aslo seen implied that a 5V signal which the DVI-D requires is maybe not available on the HDMI output.
How about some of you clever tech guys on the forums letting us less well gifted folks know if this is really a no-no and maybe why this is the case.
Thanks in advance for your help
Sorry folks have posted this in the wrong place ooops
While looking to find a HDMI cable solution for my Moto Z, I came across a solution for the Galaxy S7.
- purchase this cable: http://www.ebay.co.uk/itm/272686294141?clk_rvr_id=1297701036148&rmvSB=true
- enable USB debugging
- go to display in settings and set it to the highest resolution
- connect your phone to this cable using your original USB power cable
- Job done.... now you have a solution for connecting your Samsung Galaxy S7 to any TV via HDMI (works for the Moto Z as well using a usb C power cable)
Listing at ebay was already removed...
Try this:

Any displaylink hardware could send the image to the HDMI o VGA port. I have the Targus Multi Display Adapter and I'm able to connect my S7 to a VGA port or HDMI Port without any problem. You can connect a USB keyboard and mouse too! You only need to install the diplaylink app for android
There are many hardware with this technology
Does the ethernet port work with the Targus and S7?
I looking for cable for Samsung S7 it's even possible?
MHL (the primary hdmi to usb micro protocol) does NOT work with S7 or S7 Edge as of at least Nougat. They lost MHL on the 7 line actually, S6 DID support it. Unless MHL support was added in Oreo, I am highly suspect of the claim that this cable "works". I have a rif6 cube projector and this is one of my few phones/tablets that I still can't use on the included MHL microusb-hdmi cable (which works with numerous other Android devices). DisplayLink may work but is an entirely different premise. DisplayLink uses proprietary protocol to send encoded video over usb or wifi. With the display link app installed, yes you may be able to wired/wirelessly output your display but this is similar to screen casting and encodes the video, not a raw hdmi out video cable. DisplayLink also assumes you actually have a DisplayLink capable display or device to cast to (which I sure don't haha)
Can anyone confirm this is still working on latest oreo firmware?
Also, allebay.amazon links are dead, what should we search for?
I am interested in getting one of these until Christmas!
I second that. Can anybody confirm any of these work?
Seems plausible
I cant be sure, but I'm pretty sure you need the microusb to OTG connector that came with the s7....it allows you to plug in standard USB devices such as flash drives, game controllers, etc. You then purchase a VGA displayLINK (not displayport) external USB graphics card....plug vga from USB graphics card to tv/monitor.
USB device handles graphics control..
App acts as linux/android driver so no need for MHL anything....android is an OS...
Sounds workable.....
worth a 30 - 40$ RETURNABLE purchase.....
Looking for VGA displayLINK external USB Graphics card
Would love to try the below suggested solution. I have the Micro-USB to USB OTG adapter that came with the Samsung S7. I've got VGA cables and a tv that will accept VGA. What I don't have is the USB to VGA adapter that is described below. Can you point me to where I can buy the correct item?
I see some USB to VGA adapters on Amazon, but not sure if they'll work with this set up. I'm new to this forum so I can't post links to outside sites, but just search Amazon for "USB to VGA Converter, USB 3.0/2.0 to VGA External Video Card Multi Screen Display Converter Support Resolution 1080p for Win 7/8/8.1/10 Desktop Laptop PC Monitor Projector HDTV [No Need CD Driver] " and you'll find what I'm talking about.
I thought displayLINK was way to wirless mirror my screen. That's not what I'm looking for. I can already do that with Chromecast, ClickShare, etc. I want to have a cabled connection to have in places where I don't have an internet connection at all. This is for business presentations, so I'm not concerned about lag for gaming, nor am I concerned with perfect resolution or even audio. I just want to display screen of my Samsung S7 on a larger display with a cabled connection that doesn't require internet.
