I have an ASUS Transformer and a ShowWX Classic Laser Projector. The laser projector comes with a VGA dock that allows you to connect it to a VGA device. I purchased an ASUS branded adapter/converter for HDMI and VGA (specifically, mini HDMI to VGA). It connects to the device fine, and the projector seems to recognize that something is there...but it says unsupported video.
This may be because the resolutions are wrong. The projector supports WVGA (848x480) resolution. I think the transformer's resolution has to be set to this, and force it out of HDMI somehow. My device is rooted.
Any advice? Thanks.

In troubleshooting this, here's the next step I'd take:
1) Instead of connecting the projector, connect to a VGA monitor. Usually, VGA monitors have a bit more range in supported resolutions. If you can get a picture on the monitor, you are on the right track. You can fiddle with the resolution to get something compatible.
One thing that's important to remember is that converting HDMI to VGA is a signal-conversion process. HDMI is digital and VGA is analog. Converting from one to the other is not a simple physical thing like using a gender-changer, coupler, or y-adapter. The signal needs to be processed and converted. There is no such thing as a passive (i.e. unpowered) signal converter. Just because you can get a physical adapter that allows you to connect one to the other is most often NOT sufficient. Some laptops that have only HDMI also put out an analog signal on some of the HDMI pins. This is to be used in conjunction with a passive HDMI -> VGA adapter. Remember that this only works because the device has been built to support a passive adapter. To my knowledge, the Prime does not fall into this category.

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.

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?

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 ..
Well.. I haven't this one untill now. But i want to know if there are any body has the same idea with me.
A simple cable adaptor will not work, because for that to work, Asus has to specially support outputting a compatible composite analogue signal through their HDMI connector, which I don't think they will. However, they have announced a standard VGA adaptor, with that you can connect an analog TV with a VGA input. If you have an even older TV, then you'll have to use a HDMI to RCA converter box like this.
Like above, you'll need an active digital to analog converter cable (it either is a box or requires some batteries with a bulky part in the middle), since the Transformer only outputs digital signal (speculated). With the VGA adapter becoming available, you can go VGA Adapter -> VGA to RCA and it should work (I'm assuming the VGA adapter will also output sound with RCA or 3.5mm jack)
there must be a build in analog signal within the HDMI output, because the adapter is only a cable. and i dont think there isnt any converter in the HDMI VGA cable.
i think these two will perfect match for our problem:

HDMI only has digital signals for both video and audio. You will require an active HDMI to Composite video box. Search Amazon for "HDMI to Composite video".... can't post links yet

Yes, a standard HDMI output is purely digital, but I think Transformer's HDMI output is designed to be reconfigured to output an analog VGA signal as well (a port is just a set of pins, you can output just about anything as long as the underlying hardware supports it; like some phones can output a HD video signal through a USB port etc.. ). I say this because photos of the announced mini HDMI to VGA adaptor is too small to be an active converter.
I have a hdmi to component and VGA converter at home,
So can test this for you tomorrow when I get home,
There isn't any reason why a adapter won't work,
To get a analogue signal then the VGA adapter for the transformer connects to the data port at the bottom,

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.
micro hdmi to vga converter
i bought a Accell J129B-002B Micro HDMI (Type D) to VGA Adapter to use with a dell 1200mp for presentatins.my problem is that when i plug it the tablet shows down at the bar that hdmi is connected but nothing shows on my projector. i also try on my viesonic monitor and my vizio tv and nothing.however i am using a vga male to vga male cable since the accell vga is female.i am wondering if that is the problem and i need and vga male to vga male adapter instead. any help will be appreciated
No, you have the right cable. I just bought one myself, and used a long microHDMI to HDMI cable for a presentation. Did you remember to plug in the adapter to a USB port as well? The adapter requires power because it's doing a digital to analog conversion.
I'm using the official ASUS hdmi to vga adapter that works perfectly without issues. Used it for two presentations already. It was quite cheap as well (~25 Francs = ~25ish $)

yeah i tried connecting the usb to the dock and also using the power adapter that came with the converter. im wondering.... what did u use to plug it to the projector a male to male vga cable or a male to male vga adapter.because the accell converter is hdmi to micro and the other side is a female vga plug so it wont connect directly to the projector so i usea vga male to male cable from a computer.the hdmi part i tried using the one that came with the converter and a media bridge 6 ft micro to hdmi cable i own and nothing. when i plug the converter it turns a green light

you are on ics?maibe my adapter is broken.when i use the micro to hdmi to my tv or pc it works.so i know is not the cable.
i just pluged my computer to my hdmi monitor using the accell adapter from computer hdmi to monitor using vga and the accell converter worked.also my micro hdmi works when connected directly.so i guess the micro hdmi on the prime and the accell converter works.so im out of ideas as of why it dosent work.any help will be apreciated.

I think the prime will only output 720p (1280x720) but i havent checked since the new update .21 they seemed to have changed something. Will check later if there are more options now.
Its certainly possible though, this is only a matter of software. The tegra3 GPU is more or less a low energy version of what we have in our Desktop PCs. They can output all kinds of resolutions but you need a tool to tell it what to output.
[e] you now have some options if you want to scale or crop the image. No actual resolution change. One thing i noticed though you can output 3D content to a 3D tv or something if you have one, there are settings for this now This Tablet is so awesome^^
I saw does features.I wonder why everybody's hdmi to vga works but mine.

Having sort of the same issue, I have a microHDMI to HDMI, plugging the HDMI into a DVI-? adapter (the one without the pins around the horizontal plug inside the male end). Shows HDMI connected but nothing displays, and iirc the DVI is digital. I very well could be wrong but there's no way to power that adapter.
Haven't bought a VGA adapter for this reason ;p
I saw that adapter but I went VGA bcz of all the good feedback and this crap dosent work.I wonder if d Asus one is any better

The prime CAN and WILL output 1080p to HDMI if the source content supports it. If your video can play 1080 and the player supports it, it will work. Confirmed by dozens of people in various threads.
As to adjusting the VGA resolution... VGA is limited by the technology it uses, to a maximum resolution of around 800x600 with limited colors (think 16 bit colors). With the color depth were used to you are limited to around 640×480. Nothing i have found anywhere has suggested that they can use standard VGA to output anything higher. Even HD video players (hell, a blueray player) with a VGA connection on it is only outputting at 640x480. Limited by the technology in the cable and the architechecture of the cable. Keeping in mind, VGA is ~30 years old, older than most of the people on the forum i dare say
Long story short: no VGA adapter i know of will do anything higher than 640x480. Use HDMI or DVI for higher resolution.
I guess mine is bad or something,so bottom line is im going to return this thing and maibe by the asus one or something else.
I have to beg to differ, pileot. I'm an A/V tech, and I have used VGA cables for much higher resolutions than you mentioned. As I said before, 1024x768 is standard resolution for most LCD projectors, and VGA cables have no problem passing that signal.

I think it may be helpful to clarify some terminology here. "VGA" was first introduced on the IBM PS/2 back in the late '80s, but in modern computer terminology it has come to mean two different things: a video resolution of 640 by 480 pixels, or the 15-pin D-sub connector designed to carry that signal. If we're taking about hardware, then we're referring to the latter. So, I have the Asus VGA adapter connected to my Prime, and I have a 22" Dell monitor connected to that. The Prime's screen is displayed on the monitor at a resolution of 1280 by 720. If I plug that same monitor into a computer using the same 15-pin D-sub cable, it can handle a resolution of up to 1680 by 1050. If I connect my Prime to my flatscreen TV at home with an HDMI cable, I can get even higher resolutions, up to full 1080p HD. So, the VGA adapter does seem to limit the output resolution to a degree, but 720p HD still looks pretty decent. It would be interesting to try a micro-HDMI to DVI adapter, and see if you could get full 1080p HD that way. Since HDMI and DVI signals are electrically compatible (no conversion required), it should work.

+1. I'm using monitors at 1920x1080 with VGA, I even had my 360 outputting 1080p and 1080i using the VGA cable to my television.
VGA supports high resolution, it's difference is that it's an analog signal and not digital

Lol, guess were both right, in a way, depending on how you look at it. Thanks for the education!
Theroetically, DVI and HDMI should both do 1080p no problem. In fact you can get HDMI to DVI cables usually used from going from a computer into a tv... only issue is it does not pass through the sound.
well i went a head and contact accell and they told me to return the unit as it seems is defective.i went and bought the asus micro to vga converter and it worked right away when plugged in.so it seems that the accell converter was not working from micro hdmi to vga but from hdmi to vga was.im happy since i need it for tonight for a church presentation.so amazon here it goes back this accell defective thing.
I wanted to connect my samsung s3 to an old viewsonic 19'' lcd monitor (VX922) which has vga and dvi-d inputs. To do this i bought following :
1. MHL adapter (which works fine i connect my S3 to my sony tv with hdmi in)
2. HDMI to VGA convertor
3. HDMI to DVI-D convertor
I have tested each individual components and they work fine. However, when connected to this monitor i do not get any display neither in the vga mode or the dvi-d mode either. Monitor too works fine otherwise but would not work with this setup for some reason. In vga mode with the mhl/vga convertor in place it simply shows a green screen but no pictures. I checked the cable with the same monitor using my laptop and that works fine. Then i tried the mhl / dvi-d convertor option but in this case my s3 continuously shows hdmi connected / hdmi disconnected and does not work either.
I have been working on finding the issue and it seems like to me that the max resolution currently supported by the monitor is the issue. Max resolution it supports is SXGA (1280x1024) and it seems that is not compatible with S3. I wanted to know if there was to lower the resolution which is coming out of the mobile? Has anyone else tried something similar outputting video to a vga or dvi port in the past?
