MHL to HDMI adaptor cable

Hello all,
Today I was excited to find a cable that I'd ordered last week from Hong Kong on ebay had arrived.
Micro USB MHL to HDMI Cable Adapter HDTV For Samsung Galaxy S2
Well if it works on the S2 then it probably works on the Note. Well I plugged an HDMI cable into my Dell 1920 x 1200 monitor, that cable into the adapter and then a micro USB power cable into the micro USB power socket of the device.
Doesn't work
Hmm. Its a pretty simple device. Well I tried swapping micro USB cables in case it works differently with MHL or non MHL cables. Still does nothing. Damn.
Maybe it requires particular software to drive the video. Well no joy yet. If anyone has some suggestions then I'm happy to hear them. It was pretty cheap. But I wish it worked...
In case you were thinking of getting one of these. Here is the one that I bought.

Are you aware that it needs power? In your case, your device needs to be connected to computer usb (as it said in item description)

Cable can't too long.
Sent from Taiwan.

I have a similar one to that from China or somewhere and works great, do need to plug in your mains charger for it to work though. Only issue I had was you I needed to screen fit on my telly because it wasn't fitting properly but after I ran that it fit to te screenproperly.

Good news that MHL is working on the note, especially after the news of the Pioneer AppRadio 2.

I wasn't clear enough in what I wrote. I plugged in the micro USB power cable into the devices micro USB power socket just like in that picture, so yes I gave that a go but still didn't work

I bought a Menotek brand adapter off Amazon, and it works great for me. My TV luckily had a USB port (for firmware updates), and it powered the device just fine.

i bought one off ebay and according to the seller it is the original one
it works great
but you need to turn off the data (3g) because it causes disconnects on the lcd

Looking for a micro usb to rca adapter for tv

Hey everyone, I unfortunately don't have an HDTV, so I can't use an MHL adapter. So can anybody recommend to me a good micro USB to RCA adapter that I can use on a TV?

Ummm wow. Uh you can pick up a MHL adapter and maybe try to convert HDMI to VGA (analog signal) then VGA to RCA.
The HDMI to VGA convert the signal from digital to analog required for what your looking to do.
I suggest monoprice for the adapters because it may not work. I think the phone requires some kind of communication from the TV before it will output at all.
Maybe go to radio shack and ask them. They work off commission and usually let you try the parts in the store before you buy it.
LTE EX Galaxy Nexus CM9
Asus Transformer Revolver

I was looking at monoprice and I couldn't seem to find one cable that would do it, and I was hoping that I didnt have to use adapters on adapters to get the job done.
I found this on amazon: http://www.amazon.ca/gp/product/B00...&pf_rd_t=101&pf_rd_p=463383511&pf_rd_i=915398

but unfortunately it goes from the headphone jack, which I would assume doesnt send out the picture quite as good as from the usb, but hey for less than a buck (canadian) what do i got to loose right?
But I would still like some suggestions on what I could use through the micro usb

Please don't order that you are wasting your money, the phone doesn't support analog out of the headphone jack. Also you can't convert a digital picture to analog via cables. There is no way to go from HDMI to RCA without expensive conversion in which case you should just buy a HD TV.

Damn not the news I was hoping for, thanks though for the insight!

Search Amazon for B0047PDBP0, you've looking for an HDMI to composite (not component) video converter. However, even a cheap one is ~$50 and the quality won't be great even with a good one. You may be better off putting that $50 towards an HDTV. Amazon also has a few cheap 720p models in the $100-150 range.

Really??????

this is true. i tried this one and it only does the audio...no video.

I hate to say it, but after all the crap you need to go from MHL to HDMI to component to composite, you'd be cheaper off with a 20" HDTV from your local electronics store.

you can get an HDMI to rca (component) adaptor without expensive conversion..
there are cheap ones on ebay.. i dont know if the phone outputs the required data for this cable to work, however.. has anyone tried? i'm interested because i only ahve composite video available on the screen in my car

Without d/a conversion the signal is still digital and not analog regardless of the plug(s) the adapter changes the HDMI cable into. If your screen supports a digital input, then it might work, but I doubt it does.

if you already have an MHL cable, then youre $50 away from getting what you want http://www.monoprice.com/products/p...&cagpspn=pla&gclid=CNiDrvDUmLQCFelDMgoduyAAtg

Questions about HDMI dock

First of all, I already ordered original Samsung MHL adapter, as it's much cheaper, and I will use it from time to time. I also got the audio dock for charging, and not use the usb. And ordered original Samsung OTG adapter.
Now for my questions, from what I know, the HDMI dock can charge, and use HDMI to connect to TV, but it's limited to videos only? or not?
and second question, what if I connect OTG adapter to the microUSB on the dock? will it work? or it same limited port, like in MHL adapter?

What, no buddy here have the HDMI dock?

I read something somewhere that running pre-4.0.4 stock would actually allow the HDMI dock to function as a mirror. I didn't have this with AOKP 4.0.3 however. My phone is limited to just video (Currently 4.0.4 AOKP). I'd love it if I had the option to use the dock for mirroring.
The OTG adapter shouldn't work with the USB port, as it's limited to charging, no data. Says so in the manual for the dock.

Ohh, I just not sure if to cancel the order of MHL adapter, sure it's more handy, and small, so if I go to a friend, I can get the adapter with me...
The thing is, that here: http://www.droid-life.com/2012/03/23/review-samsung-galaxy-nexus-hdmi-portrait-desktop-dock/
according to manual it say:

So they recommend to update the ROM to thelatest, but they also say it limited to video only. on other hand, pre 4.0.4....yes you guess it, there was no any dock settings in the ROM, but it worked just like the much cheaper MHL adapter, I already spent some cash on the Pogo Dock, so my microUSB stay still ,
I know it more good looking with the dock, but if it really limited, then **** Samsung.
P.S, can anybody here comment on latest stock 4.0.4? is there same limitation to video only? because, you see, I have HTPC in one room, and watch movies and other stuff with it, so spent money on some sheet I may use from time to time, is stupid, as the Pogo Dock at least save my microUSB port, and even have line out with an option to use optical cable, but the HDMI dock, only can show videos, so why the **** I need it then ? I do see it good with emulators if I not at hotel or something, but if MHL adapter can mirror, and it cost much much less, why buy that dock? also some aftermarket HDMI docks can mirror the screen, like that:
http://www.ebay.com/itm/Samsung-Gal...s_Adapters&hash=item2ebd72c665#ht_2529wt_1859
hell, that thing, can charge, sync, and mirror hdmi, and even can work with phone in a case, **** Samsung guys, aftermarket sometimes can be over 9000 times better that original, to bad there no pogo aftermarket one.

Bump

I have both OEM OTG adapter and MHL adapter for my GNex. I am running IMM76K deodexed, zipaligned. I can view files from flash drive, connect external drive, or do almost anything you can do with a computer using OTG adapter. And I can mirror phone on TV w/ MHL adapter w/sound and everything.
Sent from my Galaxy Nexus using XDA

The thing is, that the phone recognize the dock as a different accessory, not like regular MHL adapter, but most people I asked, on 4.0.4 it not mirror .
anyway I ordered the MHL adapter, and OTG, original Samsung BTW, I will need them just in case, but that case both cost less then that crap dock, but I could not resist not to buy the pogo dock , I know it not cheap, but it a cheap price for working micoUSB port
PS, check Kidigi docks, they support MHL, and even can charge second battery, sync, charge, and fit a phone with a case on it.

I bought the official pogo desktop dock from the Play Store for my GSM Nexus with CM9 nightly on it.
The dock's micro USB port ONLY works for charging!
If you plug it into a computer's USB, it will charge but will not connect, manually even says not to plug it into the computer because it may damage the dock, says to use a charger.
So not sure if OTG will work or not.

I just opened the box. Plugged in a USB drive in the back of the dock, no power is being supplied to the drive. I am not using an OEM Samsung otg cable. If undock and plug in the USB drive straight tot the phone it world no problem.
I will try with a powered HD and ill experiment with mirroring and non video outputs
edit: the dock does work with the OEM extended battery (w/ no case), it's a little tight, but actually fits pretty good

[Q] How can I run MHL adapter and wireless keyboard at the same time?

I don't want to shell out for the smart dock and I think this 4 port usb hub(non powered) would work. I would plug the USB OTG cable in to my note 2, then plug in the USB hub, followed by my Logitech K400 in to one of the four port, then a MHL adapter to one of the four USB port, run power to the MHL adapter, then an HDMI cable from MHL adapter to the TV when ever I want to surf the internet using my phone using wireless keyboard/mouse and displaying it on the tv. Will that work or will I need a powered USB hub?

How did I miss that! So if I get a female micro to male USB will it work? I mean will the HDMI signal still pass thru the hub out to the MHL adapter. Let me go watch the note 2 connectivity where that guy hooks half a million thing thru his powered usb hub.

no, the mhl adapter for our phones is the reason we have 11 pins in the micro usb port. the mhl adapter uses the 6 extra pins and thus the phone doesn't transmit hdmi signal through the 5 normal pins... also the mhl adapter only works if your phone is being charged through the extra usb port on the adapter itself.
I know you next question will be well then can I connect the usb otg adapter to the port on the mhl adapter. well for that you would pretty much have to build yourself some converters. you would need to supply power to the phone while at the same time supply power to the usb items you are trying to use. this presents a peculiar problem usb otg relies on shorting the grounding wire. if you make it shorted no charger will allow current through, if you don't short it the phone won't recognize that it had to become a usb host controller. you might get away with using some diodes to make the phone think it's shorted while the chargers think it's not, but I don't know enough about the whole process to know if the software on the phone would utilize that correctly... bottom line is I don't think it's possible.

I was hoping I could use the logitech 400K while using the MHL adapter to TV. I guess I need to spring for a bluetooth keyboard or get the smart dock for 50% off while it is still on sale.

you could however take apart a dock and see how it's built (the Samsung dock allows for both usb and hdmi)

Inserting multiple USBs at the same time: possible?

Hello there, fellow members!
Last night with a friend we were discussing some stuff about the Ouya, and the next idea came into my mind: I would only purchase one because of the emulators and being able to connect it via HDMI. But wait, I can actually do that with my phone. What if I plug in an HDMI cable, a PS3 joystick and the charger into my ZL? It would be a nice way to play PS1 or N64 games. But yes, then I realized that the phone only has one USB entrance, which is the same for any of the above mentioned pheripherals.
So, what brings me here is the following question: are there any USB adapters with multiple slots compatible with our phone? If I tried a generical PC one, would it work? Or using three different functions in a hole that's made to support one at a time could damage the phone?

One of these, for example (combined with a mini-usb adapter on the cable), would work?
Thanks in advance, and best regards =)

I don't know if our ZL can handle multiple USB devices. But if you want to try it, you would need a USB Hub with external power supply because I don't think that our phone can put out that much power.

I think the Ouya has several device-exclusive games, but the ZL can play indeed Android games and emulators.
However, I think the only way to do what you have in mind is to:
1) Connect the PS3 'joystick' via Bluetooth. That way, you won't have to use the MicroUSB port.
2) Have an MHL cable for the MicroUSB to HDMI.
However, with point #2, powering the device will still be uncertain. The MHL (2.0) specs allow for powering your device when connected, but
A) Your TV will have to support MHL as opposed to HDMI.
or
B) Your MHL-to-HDMI adapter works as backward compatible HDMI, and requires external power to work.
In both cases I don't know whether the phone will charge and if it even does, whether the power will be sufficient to compensate for the (added bluetooth) power usage of the device.
It is for this 'contraption' that I initially wanted a device with both MicroUSB and MicroHDMI port, so more connectivity would be possible.
Anyway, I ordered all accessories I need to test this (but I don't have an MHL-supporting TV), expect info on this as I find it out.

The concept is interesting but the problem with the ZL is the battery life, if the battery will not be able to get charge, you only be able to use it for around a hour or hour and half playing games or watching videos from a 100%.
Sent from my C6506 using xda app-developers app

I hooked up my ZL to my monitor yesterday, using MHL to HDMI. Output worked when I supplied power to the adapter, sourced from the monior's built-in USB hub. The ZL was charging while the MHL cable was connected.
I streamed a 1080P MKV movie over local WIFI , other services(data connection/bluetooth/NFC) were turned off. After the movie was done, I checked the power usage and the battery level had remained pretty much the same throughout the movie.
So I think with MHL to HDMI, the device is only able to retain its battery level, rather than charging it to full. Having said that, the screen was turned on the entire time throughout the output; if I can turn off the screen while viewing, this could save the battery some more.
I'll perform more tests this weekend; I want to use Bluetooth as input device (I've somewhat given up on having Infra Red controls) and have audio played through the ZL speaker rather than over HDMI to my monitor (that has no speakers built in). Ideally I would want to combine this with my USB Host / OTG 4-port USB hub, but alas MHL and USB Host are mutually exclusive on this device.
