HDMI out MHL 5v? - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi.
I'm reading contradicting information regarding MHL for the Note 4.
Can I get HDMI out without external power?
Some adapter say S4 and above can power the adapter (11 pin) without external power other say external USB power is required.
Also I'm not interested in paying $70 for an official Samsung Adapter, I want an ebay special... I just need 720p out but I can supply 5v.
Thanks.

why dont you just get a netgear ptv3000. works great and is completely wireless.

Bcos that's TOTALLY useless for my application.

If you're connecting to a TV, I found out a while ago that it depends on the TV and the adapter.
Some adapters have to have external USB power to work.
Other adapters can be powered directly through the HDMI cable but that depends on if the TV supports that feature, if it doesn't then you have to use the external USB power (You can use a spare USB port on the TV).
I hope this Helps

It's for a mobile solution, Video Transmitter which only accepts HDMI v1.4.
Do you know which MHL adapters don't require external power, or is it a cable/phone thing? I could get external 5v, but then I'd need a BEC or another battery.

The Note 4 has MHL v3; has anyone successfully connected it to an HDMI source without external 5v with an ebay cable? If so which one?
Thanks.

wow some really nice looking extras, im glad they decided to add them this time around, i believe the desktop dock shown also has an AUX output in the back to play music on large speakers, however if this is true, i dont see an AUX input on the dock, so it must stream the audio thru microusb, and then out through AUX, very interesting, but seems likely, since the implementation of MHL!
Nice find, thanks.
From what I've heard it sounds like Samsung are not supplying the MHL or USB OTG adapters in the retail box, which is a great shame and rather poor really. Can't say I'm surprised, because Samsung have tended to follow this practice with their previous flagships also.
^ Correct, MHL cable listed on Clove website as an accessory...
Let me ask this. This is an MHL port, meaning I can plug in a regular mini HDMI or mini USB(or micro, if that's what it is) like normal? Or do I need a converter cable?
On the SGS II, MHL runs over the physical microUSB interface. It can output straight to 1080p HDMI w/ audio (and charge at the same time) as well as use it as a USB host OTG device. You'll probably have to use the adapter cable to get HDMI working. If you want to charge over MHL, you'll also need an MHL-compliant TV but you can still charge normally using another cable while simultaneously outputting video.
So yes, chances are you do need some sort of adapter cable, at the very least microUSB to HDMI.
For outputting HDMI you need an MHL cable, thats all. If you want to charge and output at the same time you need a dongle (soon TVs that support charging over MHL will come out, and then the cable will handle both, in addition to letting the TV remote control the playback device).

[Q] A few questions about connecting the Galaxy Note (Int ver) to HDTV/projector

Hi, I have a few questions in regard to connecting the Galaxy Note to the HDTV/projector.
Q1: Is it true that no matter which adapter I use, I need to supply power to the adapter? If so, could you please let me know the reason? I guess this can be done by connecting the stock AC adapter which came with the Note to the adapter via a usb cable.
Q2: In a retail store, I found the adapter in transparent plastic packaging. However, in other stores such as the Samsung store, I found one in white paper packaging (like the one shown in the attachment. I know the one being shown is for the S3). What is the difference? I asked Samsung but they only asked me to buy from their store which does not offer any discount.
Q3: What is the difference between a HML Adapter vs. a HDTV Adapter?
Q4: In some postings, some people mentioned that they could connect the Galaxy Note to a projector by serially connecting the two devices via the HDTV Adapter and a HDMI-VGA adapter. Others said that the Galaxy Note cannot output VGA signals. I am a bit confused. Is there an adapter that is capable of connecting the Note to the HDTV and a projector (of course not at the same time)? An adapter that can do so without external power is the most desirable.
Thanks.
1. Yes u need the power adapter, as phone doesnt hv enough power to output hdmi signal.
2. Mhl cable outputs digital hdmi out for an hdtv/ digital screen.
3. I would buy the one in plastic box for s2 n note. Other seems to be for s3- and i hear it has a different pin configuration. Tho im not 100% sure. I can confirm s2 adapter - in see thru plastic box works.
4. You need an hdmi to vga adapter for analog projectors, this converts digital to analog- once u have that u can project via that. I hv a projector wit dvi, if u hv a simillar projector u dont need such a converter but a cable.

[SOLVED] MHl without adapter?

Hello,
my screen supports MHL out of the box - a cable followed along with it.
Do I really have to buy the S4 MHL Adapter for getting it to work?
EDIT:
Thanks for answers! Looks like it requires 11PIN MHL

Then it should work, you should try, if it's going through the micro usb then theres not high chance it will brick your phone

Well, it's a 5-pin MHL to HDMI, is that the problem?
Wikipedia said:
Connectors
As noted in the 'Features' section, the MHL standard is connector agnostic. The different types of connections, include:
5-pin MHL-HDMI adapter/dongle
The first implementations use the most popular mobile connection (micro USB) and the most popular TV connection (HDMI). Other than the physical connectors, USB and HDMI technology are not being used. It is exclusively MHL signaling through the connectors and over the cable.
11-pin MHL-HDMI adapter/dongle
The Samsung Galaxy S III, Galaxy Note II and Galaxy S4 use a connector that is similar to the original 5-pin MHL-HDMI adapter/dongle, but it uses 11-pins in order to achieve a few functional improvements over the 5-pin design.
It supports the use of USB and MHL simultaneously. (Note that the new Samsung 11-pin MHL-HDMI adapter also has a USB On-The-Go port).
Samsung’s Galaxy S III/ Note 2 can power the MHL-HDMI adapter (when used with a non-MHL-compatible-TV). Although this can theoretically also be done with the standard 5-pin micro-USB connector, the Galaxy S III's 11-pin connector is believed to be the first smartphone that supports this functionality.
The Galaxy S III was the first MHL device to use a different connector - one that is not compatible with all other MHL devices and accessories.[9]
MHL cable [edit]
Passive cables are also available at retail that allows consumers to connect an MHL-enabled device directly to an MHL TV.

If your 5 pin doesn't work then it will require any 11 pin version (I think)

what is the difference of these two micro usb to hdmi adaptor

Micro USB to HDMI for s4
below one is cable only
http://www.amazon.co.uk/HDMI-Adapto...Micro+USB+to+HDMI+1080P+HDTV+Adapter+Cable+s4

MHL/HDMI Adaptor for Samsung Galaxy S4 S3 Note 2 - comes with usb cable to plug into power source (generally the TV itself) as well as the HDMI adaptor to plug into the TV.
Samsung ET-H10FAUWESTA Micro USB to HDMI 1080P HDTV Adapter Cable for Samsung Galaxy S3/S4 and Note 2- White - doesn't supply the usb cable to connect to the TV BUT still needs it. It uses a micro USB to USB cable - the same that you use to connect to a PC or your charger... You also needa HDMI cable to plug into the box and TV...
Other than that it's just price...
aha, If I understand correctly, the first one is a complete set that usb/hdmi connected to tv and micro usb to phone.
The second one, i will need to have another usb2micro cable.
Dammed it, from the description of the product, seems like the one with more options. Indeed it is not.
Thanks for clarify it.

Reliable HDMI CONNECTOR

I've tried a couple of devices that claim to connect V20 to tv by wired usb c to HDMI connector. They work for a while then the picture is lost or the phone itself freezes up. About the longest play I've gotten successfully is an hour but usually something goes wrong within 15 minutes.*
The phone has been out over 6 months now so I thought someone may have found a really dependable HDMI connector? I don't mind the lack of power in because I can always change batteries but phone should be able to play through HDMI long enough to watch one movie. That's all I really need hut I don't want to have to screw around with it 10 times to watch one movie.
Thanks so much for your help!
I've been wanting to make use of this feature, but haven't extensively yet. I have though gotten to make fair use of a micro-USB to HDMI adapter. A few trouble spots come to mind here.
Sounds like you're powering the adapter/phone from an external power source? How good is that power source? My micro-USB to HDMI was distinctly less reliable when plugged in since I was merely powering it from a normal USB port. Try running it entirely from the phone's battery. If this works better then it could be you really need a higher power source when using the adapter.
How good is your HDMI cable? Depending on how strongly the phone/adapter drives the HDMI signal, a lower quality cable could break the camel's back.
I've been running into a different bit of trouble with USB-C to HDMI adapters. I've found several of these, but whenever they've got a USB-C pass-through, the pass-through is strictly for power and does not carry the USB signals. The MyDP specification allows for USB3 to be passed through if 1 or 2 pairs are used for the HDMI signal, but allows for USB2 to be passed through no matter how many pairs are used for the HDMI signal. There are adapters which also include USB-A port(s), yet none which include an external USB-C with the USB signals. Grr!
I use C to HDMI not micro usb. V20 doesn't use micro usb. It uses slimport. I have one adapter which allows simultaneous charging and one strictly slimport C to HDMI. Both behave the same way. I have a high quality 2.5 foot HDMI wire.
Power source was Samsung tv usb powered output 1 amp. Point is I have the same issue with pure slimport and no charging.
The one that allows simultaneous charging does in fact charge and work but always craps out but so does the slimport C to HDMI.
Hmm, entertaining what you find when you do research. I suspect the V20 is using the "MyDP" specification, which is the official specification name behind "Slimport". Seems there are at least two other video out methods for USB-C.
I haven't done enough with the video-out feature of my V20 to have much experience yet. With a V10 whenever an adapter was plugged in without external power there were no problems, but when an adapter with external power was plugged in video wasn't reliable.
I'm interested in reading if you find out anything.

Sorry I haven't tried, but its seems to connect smoother the a wifi dongle.
does anyone know if there's a compatible dongle for the V20 with not only hdmi but also power input and usb host?
Happening to me too - Any suggestions
Your situation's description fits my problem exactly. I have a USB C to HDMI that was vouched as working by several V20 owners. I plug it into my Dell monitor to play games on a bigger screen. It works well for a while, then disconnects and popup on my screen says something like, "LG Bridge has stopped working do you want to exit?". Once this happens, it's almost impossible to get the V20 to share the screen again. It's not a hub, just a USB C (male) to HDMI (female).
