I got my MHL-HDMI cable from Amazon for $10, it's the one listed in the ultimate accessories thread in this forum. It is not working well for me at all, lots of flickering and going blank.
As I understand it, MHL should mean that the phone should be in USB Data/charging mode so it can pass data to the MHL adapter, am I right in assuming this???
If so then the problem may be that the adapter isn't communicating properly with the phone and it's bouncing back and forward between AC Charge and USB mode which would cause all kinds of problems.
Can anyone with a solid, non-flickering MHL adapter check their battery status in 'About Phone>Status>Battery Status' and tell me if it reads AC or USB mode for charging when they are mirroring over MHL HDMI??
Mine reads 'AC charging' and plugging it in I get horrible screen and audio flicker and the screen resolution seems very low. I have the AC power plugged into the MHL adapter and I plug that into the TV first THEN plug it into the phone.
It's pretty much unusable like this, seems like a lot of people are having the same issue with many Samsung phones and tablets.
Anyone resolved this on their note????

Did a little more testing and noticed something that I think may be odd, wondering if others can confirm.
I checked my battery charge status while plugged into the MHL adaptor and watching the picture flicker on and off on my TV. It read that I was charging in "AC mode". If the phone is in AC mode then surely the data connection to the MHL adapter wouldn't be working and the phone may be pulling too much power away from the adapter for it to work right??
Just wondering if you figured this out. I got the mhl adapter yesterday but the screen flicker makes it unusable.
Figured out that the flicker only happens when wifi is on. When I switch it off its smooth.
Is this the same for you?

I have the ATT Version of the Phone ... and it didndt come with the MHL Adaptor
http://www.google.com/products/cata...=X&ei=zczLT8GLCIOG6QHJhpjtDw&ved=0CJABEPMCMAA
The one I am using is from my older Samsung Infuse - ATT phone also!
I had that working BEFORE with Infuse , and works just as nicely with NOTE
I have the cheapest HDMI v1.4 cable - nothing fancy ( pack of 3 = $5.00 - free ship) ....
The only thing I am P*** about is the in INFUSE - all video's you can load ( 1080p) in mp4 ( borrowed from Itunes etc) with DIRECT TRANSFER ie the infuse didnt go thru any 'conversion' before addin to phone.
In NOTE - the same file - note wants to convert to 'mv' - and in my view = this making it NON 1080p format. Since my NOTE is rooted& unlocked , i can and able to by-pass that conversion C***..
.NOTE = does go into "charge mode' when you stop playing videos/ movies ( I have 64GB sd card ( formated for 32 apps +etc and other 32 GB for movies /videos
Ausmike or anyone else: does your note only charge when using this adapter and not streaming video? mine eats up battery when playing video and streaming and it pisses me off. Why couldn't samsung just used a simple mini HDMI or something similar
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...

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.....

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.

Another bug i noticed is the OTG. I noticed that there is a limit in terms for power draw a USB-C OTG device can receive from the USB-C port of the Mate 20 Pro. USB Power automatically shutsdown depending on a certain current draw and the scenario is somewhat random. This error has been persistent until now with the current version of the F/W (.126)
Although from the phone notification, "Supplying power to the connected device over USB" is present, you will notice from the LED indicator of device attached to the USB port shuts down right after you plug it. If you attempt to re-plug it, usb power is randomly restored.
I am using a USB-C usb hub with HDMI port as the OTG device. I tested this device with another phone (P10, Samsung, etc), power is stable.
I actually have the some problems reading my otg with a USB drive connected. The connection is intermittent. Sometimes it can read the drive and sometimes it can't. I tried it on my P20 Pro and it's working fine. It will be great if others can try it out and review it here.
I'm on version 9.0.0.183 (patch05). Thanks
No otg problem hdmi desktop mode
I am on emui 9.0.0.198 and I have no problem connecting my television through hdmi without extra power. Although at first the connection failed (tv screen showing red stripes and intermittently switching to black screen) and I had to change hdmi cable. Desktop mode worked fine after that hdmi replacement. Maybe just hdmi does not draw much power.
Mate 20 pro.
I bought a usb-c to hdmi cable, it connected to my new LG PC monitor a few times with no problems. But recently (no sure when or why) it will not connect to the monitor but it will connect fine to my Samsung series 7 TV.
The phone notification says the phone is supplying power to the usb device.
I have a ugreen 16gb USB/usb c flash that I used to use on my p20 lite and it worked fine. I tried it with my mate 20 pro and it does not work. I also have a hdmi/usb c for desktop mode and that works with no issue.
I purchased USB c / female USB adapter and when I plug in my OTG USB memory (that does not work when plugged into the phone) now works perfectly.
Hello Everyone. I have a Mazda 3 with Android Auto that does not natively support FLAC files. So I figured out a Solution where using Android Auto I am able to use MD Player to play the flac files on my phone. Now before anyone says that I am streaming over Bluetooth so it doesn't really matter. I am also able to go into my Mazda Bluetooth settings and Set Bluetooth to only be the source for Phone calls. This forces Android auto to send the Sound over USB. And there is a huge difference in Sound. For example over Bluetooth I have to crank up the sound to 3/4 to hear what I want while over USB Audio i get the same volume at 1/2. There is also a clear difference between Flac and MP3. Especially at higher volumes.
When I discovered I could do this I thought to myself let me order a USB C Hub, connect my Phone to the HUB, Get a USB male to USB male cable for Android Auto and a 256gb Thumb Drive to fill up with Flac Files. This is where my problems start. Connecting the 256gb Thumb Drive to Hub works perfectly, except that I have to use FAT 32 which is fine, since I wont be using this for movies. When I connect the Android Auto cable to the Hub though it does nothing I tried a USB 2.0 and a USB 3.0 cables to see if that would make a difference. I also tried using a USB OTG adapter without the HUB to see if that launches Android Auto and it does not work either. I tried using my old phone a Nexus 6p and it also did not work. So now I'm thinking Android Auto does not like USB OTG. Could this be Kernel Related? Or am I wrong to assume that something like this would even work on a Phone.
Additionally I bought a USB C powered hub so I can charge the phone while in the car. But when I connect power to the device it charges the phone just fine but it will no longer see the Thumb Drive. If I disconnect power it will not recognize the thumb drive until I restart. So far I have tried 3 hubs. The first one was the cheapest one I could find so I thought that could be the problem. I then tried another Hub I had lying around with the OTG Cable. This did nothing, finally I ordered a nice Anker Hub that works just fine with my wifes Macbook Air, but not with the phone. Any help or Guidance would be appreciated. I am open to installing a custom Kernel if this will solve the problem. Thank you.
Did you ever find a solution? Looking doing the same thing with my pixel 3 xl and either a thumb drive or ssd. I think it has to do with the way the otg cables are wired. The data pair might be the same for the drive as android auto. The otg cables dont have all pairs wired as a true y cable.
Thanks
Has anyone been able to get HDMI video output working via a usb-c dongle? I have tried three different dongles that work on every other phone I own and the display does nothing. Hope it's not disabled in the firmware etc.
Usb 2.0
I can confirm that IS possible to output HDMI from Find N but only if you use an DisplayLink adapter. I tried some USB Type-C adapters with HDMI (I have 2 and use then on a Samsunt Tab S6) and they didn't work on Find N. It's possible to use the USB ports but HDMI doesn't work.
For the DisplayLink adapter, I tested with an Targus model DOCK110 and after installing the DisplayLink program from Playstore, I was able to output via HDMI. Also, the USB ports are working. The only problem is that you cannot charge your Find N, using this adapter. Also, you will need a USB Type-C to USB type A adapter with this dock.
Ok but displaylink is ****. You can't really use it. Huge lag low quality. The same as wireless output

When I tested it, it didn't look too bad. Of course, there is some lag but not too much. If you watching a Youtube movie, it's not very bad; I almost didn't noticed any difference. But if you want to play games on the big TV and if it's a fast pace game, surely you will have some difficulty.
