thanks fr reply. but i didnt get you how to make it work?

The note 2 and the s3 have different hml adapters. You will also need a converter.
On the monoprice link you posted, youll notice ab asterisk next to the s3. Same applies to the note 2.

I just got a Samsung HDTV Adapter Tip (5 to 11 Pin) Model EPL-FU10BEBSTD, which has micro-USB female to male; it enabled my TMobile "HDMI connection kit" that had worked with Galaxy S2 Hercules to work now with my Galaxy Note II. The connection kit was expensive, but has a 10' cable from the MHL adapter body to the male micro-usb plug, as well as a 5' cable to the TV HDMI, and a wall charger to power the adapter body. So the arrangement is quite flexible once installed.

I was hoping someone could help me with this problem also. I have a hdmi capable monitor that I would like to hook my note2 up to but for whatever reason the monitor will not detect the signal. i have tried rebooting and connecting it various ways but no dice.
the only thing i can think of is that its the rom im using which is myrom's latest version

Do you have 5pin or 11pin mhl cable? Note2 requires 11pin one.

I was told you need an S3 cable. Here's the one I use.

Yea you guys are right you need 11 pin for the note 2. the sgs2 used 5 pin so if you have one for your older phone you need a new one or I think they make a converter too. I would suggest getting right from samsung. it may cost more but you get what you pay for usually and samsung makes the best stuff when it comes to that. Also another thing to consider while you are on samsungs website they have a multimedia dock that is on backorder right now but for a 100 dollars it turns your note2 into a pc basically. It has 3 full size usb ports so you can hook up a mouse keyboard and external hard drive and it has the hdmi port and an auido port so you can hook it up to a hdmi tv/ monitor and multimedia speaker system. I was going to get a new computer but I found this thing. So basically I can have an android desktop. It dont get better than that. Now wit dropbox and mobile odin and this exynos exploit we really dont need to hook up to a pc to root so there is no real reason for it. Just something to think about.

This is really helpful. My question is will this charge your phone while you are connected to the tv? Also, I see some of the description on ebay says it might not work if you are rooted.

I am rooted; The MHL/HDMI system works well, if that is your concern. The charger that I use for the MHL adapter is much lower amperage than the one that came with the Galaxy Note 2, so I would guess that charging might be slow if you are watching a movie that way, or maybe not even keep up, but I don't have the patience to do the test (or watch movies that way).

Hmmmm!!!!
I just got the Samsung dock and can't connect with HDMI on rooted stock.
The phone detects the dock and charges up, but no signal to the screen. Also tried hooking it up with the TV and projector using two different custom rom and separate HDMI cables and no dice.
Guess the dock is defective.

[Q] Motorola Lapdock & Note 2?

Just curious if anyone has gotten the keyboard and mouse working on a lapdock with the Note 2. The HDMI works perfectly, but the keyboard and mouse don't work. I don't know if it is possible, but it would be great if someone knows how to make this happen.
Here's a picture of my set up. Everything is connected so it *should* work. I'm thinking that it is a driver issue.
(The lapdock keyboard & mouse work great with Ubuntu 12.04, & Windows 7, & Raspberry Pi (Raspian), so I know that my connections are fine.)
Thanks!

Hmm, guess I'll be able to answer my own question after a bit of research. It seems that the Note 2 (like the S3) can't provide MHL & OTG at the same time.
Not sure if there is a way around this. I wonder if Samsung's SmartDock works, but I don't want to spend $100 to find out.

I'm increasingly interested in trying just this, smart dock + lapdock. Hard to imagine that it wouldn't work, but I wouldn't mind confirmation if anyone has tried it. The impressive low prices on lapdocks in the secondary market kinda offsets (and also kinda shames) the ridiculously overpriced smart dock.
I wonder if the lapdock's battery can provide as much power as the smart dock needs or if I'd have to have an external battery too.

the lap dock should provide 1 amp which is what the atrix needed and the chargers it came with. the s3 has a smart dock and it too only has 1 amp chargers...
plus I don't see the smart dock pulling more than 200mA it has to provide the s3 with at least 750 mA for the charge to survive mhl.
regardless amp drain in android devices is adaptive. even if the dock needs a full 800mA the phone will try to survive with the rest draining battery of course but working none the less just like trying to charge our 2A monster with a Bluetooth 150mA charger. it will try but at best slow down the discharge

I don't know if an MHL adapter will supply both HDMI and OTG at the same time but I know the phone is capable of it because this is how the Samsung Smart Doc works. 3 USB ports with HDMI out.

I got it working. I have a Raspberry Pi that connects to the lapdock perfectly so I picked up the overpriced Samsung SmartDock and used the same cords that I'm using with the Raspberry Pi and it works pretty well.
Here's the info:

Here's some apps that make the lapdock work better with the Note 2:
Screen Standby - Need Root for this one.
Set Orientation
External Keyboard Helper

http://forum.xda-developers.com/showthread.php?t=1953061&page=7
It is working perfectly with my 24inch LED monitor and a USB hub containing 2 pen drives and one wireless keyboard & mouse
Now the next move i got atrix lapdock and try to connect the HDMI out from mobile to Lapdock (with necessary adopters) but i am getting only green screen.
Lapdock is working with other HDMI sources....
Any idea on how to get my note 2 HDMI working in my lapdock?...

I've never gotten a green screen so I have no idea. And, you already did the basic troubleshooting. Are you using the Smartdock or something different? If you aren't using the Smartdock, maybe pick one up to see if it works. If it doesn't fix the problem, you can always return the Smartdock.

Based on what you are saying, it sounds like the issue is between your lapdock & MHL cable. Like I said in my previous post, I'd pick up a Samsung SmartDock and see if it works. Just make sure that yo buy from somewhere that you can easily return it in case it doesn't work.

Dear wilbr,
Thanks for the reply.
Do you use the original samsung MHL cable?...
I am using Chinese version of MHL.
HDMI troubleshooting guide says the below....
The green screen problem could be due to HDCP non compliance or syncing problem..
anything to do with HDCP and chinese cable?...
I am trying to get an samsung official MHL or a smart dock to try out. (here in india smart dock is still not avaiable). My once route to get it is through china...

Any help or update?.
wilbr,

Is it rooted or stock rom?...

If you are using Aosp, mhl doesn't work with Aosp.

I've already got a Bluetooth keyboard and mouse. I'm gonna order a MicroUSB to HDMI adapter and go that route. It'll be cheaper and less to carry. When I travel I'll just be able to plug into the hotel TV and go wild!
There's a YouTube video of someone demonstrating it, just search YouTube for "Samsung Note 2 Mobile Desktop with a Bluetooth keyboard mouse"

i had a similar problem, its was a shotty solder job on the "Budget adapter" (HDMI PINS). i took it apart and cleaned it, works perfectly now.
Plug your phone in, WAIT 5 SECONDS, Then lift up.....If you still have a problem, push F11 on the Lapdock... that manual cycles the resolution modes...at least thats what the manual says....
As far as the USB key board goes, im currently working a solution.... you have to power the MHL THROUGH THE DOCKS usb port using a donated USB cable with the end cut, solder it in directly on the board of the adapter itself, then make a micro usb extension that has the power wires cut and D- D+ reversed... I have a motorola ATRIX and im looking at the board, it looks like they have been reversed....ill post up some pics if i find this to be true.
---------- Post added at 03:37 AM ---------- Previous post was at 03:21 AM ----------
Also, sorry to bring up and old post, but I have a reason to believe that the ZOOM bluetooth keyboard uses the same 30 pin connector thats inside the lapdock (connects everything together) all the connectors are the same, except on the ZOOM the other end is a BLUETOOTH module...this would solve the whole issue... im about to get one on ebay. Ill report back in a few days.

Dex Station to Usb C Monitor....

Hi. I'm on how to connect my Dex Station (with Note 8) to my new Asus Usb C Monitor.
I tried a Piaek adapter. No go. Seems like anything made to go usb to HDMI doesn't work the other way.
There are a couple of HDMI to usb 3 converters, like inogeni but theyt are really expensive
Anyone know anything about this?

Connect galaxy a70 to external monitor with type c to hdmi adapter

I would like to know if galaxy a70 supports connecting hdmi monitor via usb type c to hdmi adapter or with any usb type c dock to external monitor. I want to mirror via type c cable and i am aware that there is no dex support for a70.
Can any one tried this? I don't have usb type c to hdmi adapter or type c dock to try this and wanted to buy if this is supported.
Thank you.

yes, i tried just few minutes ago connecting my device to computer but it's not supporting it's very weird Samsung not makeing stable update now days and i have ghost touch problem

Ok. This is bad. I was expected at least screen mirroring via cable on a70 but didn't happen.
I got dell usb type-c adapter and tried connecting hdmi cable to external monitor.
Nothing shown and nothing was detected except saying some usb device has connected.
For this price, should expect these minimal futures in the phone.
I don't recommend this phone even for camera and samsung one ui. Still sony fan so installed xperia home launcher even though it is not working properly.
Bluetooth is breaking a bit with head phones.
audio for receiving calls is poor.
Overall for this price, it is not a good product.

Hardware of Software
Is this a hardware feature or can be fixed with software update???

Tried it too. Doesn't work
I bought a Type C to HDMI converter. It worked on a samsung a30, note, but not on the A70. I should have gotten the cheaper A50. Might have worked there!

Can anyone update us? Is this a software or hardware issue? Has anyone successfully got it to work?

I think get a chromecast device and use screen mirroring feature in google home app and you will get a more convenient wireless display !!!

I think everybody knows about chrome of course but u end up using urr mobile hotspot data which is never unlimited like the unlimited data u can get reasonable an the point is cellphone distributers should include Mhl because its free to watch anything on your phone an it doesnt use up ure wifi I think carriers are catching on and are fishneting with cellphone distributers n there trying to ban it or make it obselete because they will lose money think about it watching all the movies u want from your phone and mivie channels unlimited with Mhl hdmi.an it sucks itvreally does.cause u either have to spend a fortune getting a device with mhl or the mid range nice cell phones with bigger screens normally dont have mhl

Maybe you have to use the official Samsung one - https://www.mobilefun.co.uk/official-samsung-galaxy-a70-usb-c-to-hdmi-adapter-74551

A70 connectivity problem
That's because its usb C 2.0 only the mobiles with 3.0+ can connect to HDMI

Can you charge through a USB Hub though?

Queried this with Samsung, and this was their response. Sadly it's a no go!

For this price, they should have given usb 3.0 or higher.
Store keeper told that it is possible but later i understand that meant screen mirror.

Can a custom rom add support for this?

Hdmi screen mirroring via usb cable not working

Helped a friend buy this. We were watching movies via wireless screen sharing (miracast) and it was OK but kept stuttering and dropping WiFi.
So I suggested getting an hdmi usb-c cable with power charging (4k). I was very surprised when it didn't work! Tried everything including downloading dex to the phone.
Connected the same cable to my s8 plus and it worked beautifully (dex) !
So why not the Samsung a50? Never experienced this on any phone before and have been connecting to TV this way for 10 years.
Need a different /special cable? Or no go on this device and can only do via wireless?
Thx

I haven't ever used HDMI mirroring on a phone but as far as my knowledge of Type-C goes, you need USB 3.1 to support all the alternate modes including HDMI and DisplayPort. The A50 comes with USB 2.0, so there is no possibility of getting Display-Out from the USB port.

thanks for that explanation, I'm guessing this the same reason we can't use type c 3.5mm jacks?
by that respect, pretty much any type c 3.1 can output through hdmi?
Thanks,
Scott

Type-C as a standard is a mess. I don't think you are required to support alternate modes in USB 3.1, so I suppose there are USB 3.1 Type-C devices that still don't output video.
Regarding audio, there is Audio Accessory Mode for Type-C and the concept of active and passive headphones/dongles, so not all dongles will work.

samsung A50 simply doesnt support dex. only s8 s9 s10 and Note 8 9 10.
getting usb c to hdmi wouldnt solve your problem.
there is how ever one possible solution, which is the universal android usb to hdmi cable. it uses ezcast app (same app for wireless). mirroring your phone but wont display netflix etc on your tv.

Samsung A20
So, I know that the A-series doesn't support DeX, but I was hopeful that it might still have the capability to project to a lapdock (like the HP Elite X3 or Nexdock 2) via USB-C and display even crudely (so, not the fully optimized DeX-ified desktop mode, but maybe just a mirror?), ideally allowing for keyboard/touchpad input as well. Basically I'm trying to come up with a solution for my mom whose company is phasing out the laptop she's accustomed to working on in favor of these lousy Samsung A20s, which she's gonna have a lot of trouble seeing and interfacing with on such a tiny screen and without a full keyboard (she's in her 60s). The lapdock thing is the only idea I've been able to come up with (though, it sucks that the A20s don't support DeX), but I'm open to any other suggestions if you think the lapdock route is a dead end. Thanks!

The A50 doesn't support MHL(display out protocol) at all for some reason, which is quite disappointing. At least wireless display casting works well.
