Mhl - Nexus 4 Q&A, Help & Troubleshooting

Hi guys,
Anyone know if the n4 has mhl support like its predecessor?
Cheers

It does.

Actually, it doesn't. It uses a different technology called SlimPort HDMI which is very similar but doesn't require having your phone connected to a power source like MHL does.
It also supports Miracast which is a wireless solution.

Great, thanks. Was always disappointed that my nexus 7 didn't have any way to connect to HDMI. Well my desire s is on its way out the door on the 13th.

So does this mean that it will use the same adapter, or will there be a different one that is required to get HDMI out?
Miracast does look cool, but isn't that useful until more devices include it in or I buy a receiver for it (which I will).

I'm interested in this as well, SlimPort looks nice, except the price ($30) is way higher than MHL adapters. Are we sure that it won't work with MHL?

[q] mhl hdmi

Has anyone seen definitive proof that an MHL hdmi adapter will work with the Razr M? I guess I'll know for sure when my girlfriend picks hers up but thought I'd go ahead and ask becuase I'm bored as hell at work.
Not saying that this is final, but I just picked up an M this morning and tried plugging it in to my MHL adapter. Unfortunately, the TV continued to show no signal

Right there with you no HDMI though MHL just tested it a few minutes ago.
Thats too bad, if this phone had HDMI even if I had to use MHL and ICS webtop it would be perfect. Its the first phone in a while with a pocketable size screen and decent specs.
I don't use my phone for HDMI output so I have no experience with it. There was a thread on the motorola forum saying the device does support DLNA in response to similar questions. Not sure if that helps. I looked through Target and BestBuy, just curious, but didn't see any TVs that listed DLNA support.
Allot of Samsung internet TV had Dlna

[Q] what's the difference between MHL and slimport?

(moderator: could you please move this to the Q&A section)
----------------------------------------------------------------------------------------------------------------------------
Just read this on endadget: http://www.engadget.com/2012/10/30/nexus-4-boasts-slimport-support/
Questions:
(1) What's the difference between MHL and SlimPort?
(2) Does either one of these two option allow us to charge N4 while connecting to an external display?
If yes to (2) I'm 95% for getting an N4, and if yes to (2) with SlimPort then I'm up to 99.9% (engadget claims that there will be SlimPort-to-VGA adaptor -- yes some of still needs to give presentation using VGA...)
so does that mean that mhl will not work? -=X
http://www.analogix.com/products/slimport.html
I guess it's not compatible with MHL, but apparently it allows mirroring without external power, and it apparently also supports OTG, so i guess it's basically a "better" version of MHL.
*coughs* http://xkcd.com/927/
It also has a pass-through USB port to allow it to be charged whilst being used. I wonder if it would allow it be a USB host and SlimPort at the same time.
Here's how I think it works after trying to research it. I could be wrong about some of this so don't take it as fact.
If your TV specifically has built-in SlimPort support, it means that when you connect your N4 to the TV using a SlimPort cable or adapter, the phone will actually be charged by the TV through the HDMI cable. If the TV doesn't support SlimPort directly, then the cable/adapter will still work, but it won't charge the phone, and as a result your N4 will lose battery over time. In that situation, you can connect a separate power cable (in the same way that MHL works) if you want to charge simultaneously.
more recent version of mhl should do usb OTG at the same time as Video
According to all knowledgeable Wikipedia... MHL can power devices too, so I don't see what's different between it and SlimPort.
The HDTV provides power to the connected device (5 V DC/500 mA with MHL 1.0, 5 V DC/900 mA with MHL 2.0).

Too bad... I just ordered a 2013 Nexus 7 and a slimport adaptor and I thought, perhaps this adaptor would work with my Xperia Z, too...

does this multimedia dock work with nexus 4?

i found this dock on amazon http://www.amazon.com/Samsung-Galax...id=1378589679&sr=8-1&keywords=multimedia+dock i was wondering if anyone here thinks this dock would work for a nexus. i want to connect a portable hard drive, wireless keyboard, charger and hdmi all in one. this seems to meet my needs.
I've seen a lot of comments about the Nexus 4 not supporting usb OTG devices, so it will probably only work for charging, & maybe not even that.

No, the Nexus 4 does not support USB OTG. The HDMI output probably uses MHL for USB A/V while the Nexus 4 uses SlimPort for USB A/V. This will only be useful for charging; even then it might not charge it due to the MHL chip in it.
www.androidcentral.com/android-advanced-usb-otg-nexus-4
OTG is supported in CyanogenMod's 10.1 M2
Now the question is Will CyanogenMod's 10.1 M2 support the Samsung Galaxy Smart Dock?

MHL support?

I recently put a new deck in my car, and the ONE reason I spent the money I did on it is because of the MHL capability. Now it seems all these new phones don't support MHL. None of the newer Samsung do, and it seems if I'm trying to get one of the top competitor phones, MHL is no longer an option?
Did anyone see/read/hear of MHL being a thing on the 6P? If it turns out that MHL isn't an option stock on this phone, is MHL a thing that can be added via a custom rom, or is it purely hardware?
Thanks for ANY and all help guys!!

Haven't seen any news of it, but can confirm there's hardware required as the USB port is different (at least on regular micro usb phones, NFI with USB-C). I can't even plug an MHL cable into my S6, whereas friend with Note 4 it all works easily.
M.
That's kind of what I was thinking as well. Apparently they got rid of the MHL support completely in the S6 and Note5 Line. I read that they don't even have MHL in the Nexus 6.... So I'm really afraid they might not have it here either.... Kind of sucks I guess.
I am about ready to tuck a Miracast adapter behind my dashboard. Then there's no fussing with cables or anything

An alternative solution is chromecast has screen mirroring support. Tested it last night with the new chromecast app. Worked very well.
Chromecast needs the phone to be a hotspot and have internet connectivity at start up. Works if the conditions are right, so depends on where you live.

Only bad thing about that is there won't be a way to charge the phone at the same time.
and it does not work. Apparently google took the easy road and implemented only USB2.0 with USB Type C.
This means faster transfer speed - bull
Fast charge only because of qualcomm quick charge 2.0
No alternate modes (MHL, HDMI)

They mentioned in their Q&A, that the usb is 2.0 because it's always on and 3.0 takes more power apparently.
Not sure if correct, just relaying info

From what I understand, this phone does not support Qualcomm's QuickCharge. Every Google page on this phone says "Fast Charging". That's freaking bogus, too. It's part of the Qualcomm 810 processor. Why the heck not??? If the hardware is in there, its possible it could be enabled through a kernel tweak. No guarantees though.
And for that matter, that processor supports wireless charging through metal. Just give me DISPLAYPORT!

Uhh yes it does support quick charge. 10 mins charge give it 7 hours of use if I remember correctly. This isn't the Oppo OnePlus that tries to sugar coat things and sell you garbage.

Will either the Nexus 5x or 6p support HDMI via the USB-C connector?

DB> Nope. But Cast mirroring to ChromeCast or Android TV has got really good. And Chromecasts are only $35. And we have new ones announced yesterday.

MHL and HDMI will not work on the 6P. The direct answer from the devs:

Unfortunately, it does not support "Quick Charge" Everything Google has said is "Fast Charge" which is not the QC standard. All your chargers you have now, are slow and useless to the 6P.

So far Sony is doing a really good job with keeping the Xperia line with the MHL connections.

I was doing some research and found this thread. That CRUX looks interesting, but seems like Chromecast may be the way to go for $35.

Possibilities of USB C on Nexus Devices?

We have seen that on Macbook air 1 USB type C port has been utilized not just for charging but also being used as display port as well using an external adapter.
Will Nexus 6P/5X have such functionality using an additional adapter or directly may be to connect to HDMI TVs or connect OTG drives?
No. Disabled.
OTG should work, HDMI will not. I'm interested to see if the Pixel C has HDMI enabled. I would expect it to.

It does, and Google even sell a C-HDMI adaptor for that (only listed in the 'works with Pixel' section, though - not the Nexus sections).
Otg works... They confirmed and sell it on the store

It's not "disabled", just N6P doesn't have USB Type-C 3.1.
Could you please explain more?
In the Type-C spec (.zip found here http://www.usb.org/developers/docs/) it defines what pins and wires are used for what. In a Type-C port or cable there are 2 dedicated pins/wires for USB 2.0. For USB 3.1 communications there are dedicated shielded twisted pair wires used for high speed communication. To support Display Port/HDMI, the Type-C port switches the use of those high-speed data wires over to that kind of output. (I think they called this alternate mode.) Anyway, the Nexus devices only support the USB 2.0 mode. It is unclear to me which of these is the case, but it basically means that either the USB controller in the phone can't support it, or the physical pins in the port are missing to connect and use those high speed wires. (Or both.)
It is possible it is just disabled in software, but that doesn't quite make sense to me. Why include all the hardware you need to enable USB 3.1 speeds, HDMI output, and a slew of other features such as USB-PD... But simply choose not to enable them? Seems far more likely to me that the lower cost of the USB 2.0 only mode (less complex controller and port) were used instead.
Hope that helps.
