Help Screen mirroring

Are you using one of these?

Mine works fine with my Galaxy Nexus, but no luck with the N3. I see a different version on Samsung's website in the list of compatible accessories, but I have no idea what the difference would be. Other than the color and shape, obviously.

Samsung site; MHL adapter for GN3

The MHL 2.0 is the one I have which I think is the latest. It's the one at the end of your link. No luck with getting it working. :(

The Note 2 smart dock will work with the Note 3. Look it up in Youtube. ;)

If the connection is not working, try to remove and reinsert the MHL adapter. If there is still an issue, remove the MHL adapter, reboot the phone and try again.

If that still doesn't work, then there could be something wrong with the adapter. Make sure it is an 11-pin connector and not the 5-pin connector. The 11-pin connector head is different in shape. It should not look like a standard microUSB head. If it does look like a standard microUSB head, then you have a 5-pin which will not work and the cause of the issue you are experiencing. In this case you will need a 5-pin to 11-pin adapter. You can find one for cheap on eBay.

I have not had any real issues using the Note 2 with the 5-pin to 11-pin adapter+MHL+HDMI to PC Monitor, TV and HT projector. As well as the Smartdock. Granted, there are times where it will flake out on me, but a simple reboot tends to fix that.

That means you have the standard 5-pin connector. It is not an 11-pin connector. You will need a 5-pin to 11-pin adapter if you want to have the Note 3 mirror the screen.

Here's an image of what the heads look like. As you can see they are different.



And for those wondering why: this 11-pin configuration allows both USB OTG and MHL to work together simultaneously (ie. Samsung Smartdock). The 5-pin only allows you to connect MHL or USB OTG only. They cannot be used simultaneously together. I find this a much added benefit as I can use it as a mini backup system (keyboard, mouse, USB hub, external HDDs, flash drives, etc with output to a monitor).

The drawback is that the 2A charger is not sufficient to charge the Note 2 (powering the MHL connection/USB though Smartdock). Even with a powered USB hub connected, the Note 2 will still lose charge when connected. Albeit not a huge drain, but it will still drain the battery good.
