Screen mirroring not working with my TV - help - Galaxy S 4 Q&A, Help & Troubleshooting

Hello,
I am trying to get screen mirroring working between my LG smart TV and s4. I am sure people will say it can't be done with non Samsung products, but check this link from YouTube. video
The problem I have is that the TV can find my S4, but the phone refuses to find the TV. Is there anything I have missed somewhere?
The TV offered to open a screen mirroring connection to the phone, but the phone never displays a dialogue and the mirroring fails.
Has anyone managed to screen mirror to a device other than Samsung? The TV fully supports dlna and miracast, but it's the miracast screen mirroring I am most interested in.
Thanks,
Andy

Yes, it does work with a LG Smart TV. I have it too. But only if you use a fully stock Rom or a Google Edition Rom like the untouched one from MakTail with it's default kernel. Also cm10.2 Roms are working great with then called Wireless Display. I love my AOSP browser on big screen

ok, so what am i missing? I have a fully stock (saudi arabia S4) and the TV just doesnt show on the S4. The tv can see the phone fine, is there any settings somewhere i might have missed?

It is the other way around. The phone screen should be visible on your TV.

Sorry i should have said it more clearly;
When i select screen mirroring on my S4 the TV does not show as an available to device to mirror to. They are on the same wifi network.
If i scan from the TV for mirror devices then the S4 shows up. The TV attempts to set up a connection but the S4 does nothing.

In you TV settings does the TV show the word Miracast or only WiFi Direct? It only works if your TV really shows Miracast otherwise you can only use apps on your TV like Youtube and casting button.

Ok, so assuming that connectivity works fine, based on the fact the TV can see the phone, why doesnt the phone connect with the miracast compatible tv?

Don't but many devices don't play well with others. Is your TV maybe a "draft" Miracast compliant one??

Sorry, but have to ask - does your TV support it? What is the model#?
If it does, you should be able to enable it then just turn on screen mirroring on your phone.
My Samsung TV doesn't have the option for screen mirroring built in, but I accomplish it with what I do have - the MHL HDMI dongle and the allshare cast. One is a direct connection, the other is wireless.
I'd imagine it works the same as the allshare cast hub. When it's on,all I need to do is turn on screen mirroring from the notification window and it automatically connects to it. If you share the model of your TV myself or someone can look it up. Or you can check out your manual first then go from there. Without knowing what you have, here's an example :
http://www.samsung.com/us/support/howtoguide/N0000058/6528/41579/UN55ES6500FXZA
AFAIK it has to be a newer model for the mirroring without the dongles. : http://developer.samsung.com/forum/thread/is-it-possible-to-test-screencast-using-eclipse-simulator/141/219986#post1
Hope that helps.
Can a rooted phone screen mirror? I just got a new 60in samsung but I cant get mirroring to work. It connects and then drops a few seconds after.

I had to update the ROM in my smartv before I could connect my phone to the TV and then toto the phone. Some samsung devices can mirror the TV as well as have the TV.

LN32D403E4DXZA specifications don't indicate built-in support for miracast. So you would need to get either the Allshare cast, or another miracast adapter like the netgear push2tv (PTV3000 or PTV2000) to be able to mirror your phone to the TV.

Certainly.
Personally, I find that short cable inconvenient, but that's just me. If the goal is to play movies on the phone and mirror to TV, sure. But I end up wanting to share pictures or short videos taken on my phone, on the big screen. For that, I would prefer the ability to have the phone with me (on the couch) and not have to stand next to the TV with that short cable connecting it to my phone.
For now, I'm using the Roku (juice channel) to share local video/pictures, but is not the best option because it doesn't let me share my pictures/videos from dropbox or other online storage sites. I have to download it to my phone first.
Waiting for the wireless mirroring options to drop further in cost

For sure! I prefer not to have it directly connected -but was more for the sake of informing the OP.
I use the mhl dongle it like you mentioned, if we're watching something that doesn't require me to babysit the phone lol.
I got lucky when Samsung was having a 50% off promo and I picked up the allshare hub then. None of my TV's are "smart" TV's, so it works well for my "dumb" TV's.
Also, a while back, I picked up a pogoplug for under $20 and I use that for storage- kinda like a "mini NAS". You can hook up usb drives (flash or harddrives) to it and right now I basically have a couple of flash drives to serve the media to phone, so it's cool for mirroring or just while out and about. Pretty cheap,quick and doesn't require much effort so it was well worth it for me...it comes in handy because it's set up so I don't have to do any transcoding for videos - I just use the mxplayer app and the phone does the rest.
There is one thing I have yet to try, just for curiosity's sake - to run xbmc on my S4 while it's connected to the TV with the wired MHL dongle, then use my wife's phone or my tablet with an xbmc remote app to connect to and control the videos to play from the s4 while mirrored...
That's cool with the roku. Have you tried just using something like couchyplay http://www.roku.com/channels/#!details/19661/couchy-play
or rodropbox http://www.roku.com/channels/#!details/18042/rodropbox so you don't have to d/l to your phone from dropbox?
You could even use something like the cloudpipes app https://play.google.com/store/apps/details?id=com.maximussoft.cloudpipes&hl=en to automate moving/copying files back and forth on dropbox while you're not using your phone (at work or sleeping ..or whatever)

Miracast works well on my F-Series Samsung TV. It won't connect with Samsung Allcast, even though both devices see each other, but the screen mirroring works through Miracast using Wi-Fi Direct.

Not even close. The process is buggy, but it does work . However, using a Samsung GN 2 with Allshare on the same Samsung Smart TV worked as it should, with no picture degradation. I use it almost exclusively with online broadcast apps, so various other factors are at work, like wireless signal strength.

[Q] S4 & LG Smart TV Screen Mirroring

Hello everyone,
I apologize in advance if it was asked before.
I have a 47LM6400 smart tv from LG with screen share function.
When I enable if and screen mirroring on S4, it finds my phone, but the phone does not find the tv.
S4 is on 4.3
Am I missing something?
Thanks in advance

On the remote press on setting and find mira cast or something along the lines, You just have to enable it.
If you still can't find it, I will take pictures and show it to you
Thanks for the reply. My TV has no Miracast support, it says it will use wifi direct, widi, etc...
Tried with my sister's Samsung TV and got the same behavior: the tv finds the phone, but the phone can't find the tv.

Well... after some time spent on the phone, it seems that only LG Smart TV's w/ Miracast support (which is not my case) can do wifi screen share. The functionality of mine is restrict to it using Intel's WiDi. Damn.

You need another device, usually a Miracast-supported TV, or a Miracast-supported HDMI dongle, to get the mirrored screen.

Screen mirroring over WIFI ?

Hello,
Just got the Nexus 6P , after years with Samsung note series... I was wondering , is there anyway in Nexus 6P to do screen mirroring over the wifi ? without any dongle?
I tried the Cast option , but it did not recognize my Sony tv which is connected to the same WIFI network, while the Samsung note had that "screen mirroring" option built in, is there anything equivalent in the Nexus?
Thanks, :good:
Roy
The cast option is designed to be used with a Chromecast. Some TVs and other video devices will register as Chromecast for some things, but not all. For example, my Vizio Smart TV shows up in the list of devices I can cast to in Netflix, but all it does is launch the Netflix app on the TV. I can't actually cast to it and control it from my phone like I can with an actual Chromecast.
Nexus devices on do Chromecast by default. If you want Miracast then you need root and to modify the build.prop file to enable it.
I can verify that if you root your Nexus 6P and add the following line to your build.prop, it will work with miracast devices. I just had it working with my screen beam pro that I bought to cast my Nvidia Shield Portable.
persist.debug.wfd.enable=1
Actually it is built in! I just hooked up to my Samsung TV. Go to "Cast", tap the three dots, check enable wireless display (make sure the mirroring function on your TV is on). Bam! your connected.

This is not available on Nexus 6P (and Nexus 6 too) on stock.
I wonder why Google removed this and made it such that users have to root in order to activate Miracast....
Because they want you to use Chromecast, which is very Apple Esq of them

I can only think of this being the reason.....
I think the main reason why it is disabled by default is because Wi-Di (as Intel likes to call it) requires "certified" hardware to allow you to mirror your screen over Wi-Fi.
Same for PCs... you need a certified Wireless Network Card to enable Windows 8-10 to mirror your screen to a Miracast Receiver.
TL;DR: Don't blame Google for this..!
Not really the excuse, LG had pretty much the exact same model as the N5 which had it on as default, so the hardware was certifiable in that case. Pretty sure other Hauewi devices are also certified. Far more likely to be Google pushing Chromecast.
Well that sucks that we have to modify build.prop to get Miracast mirroring to work. I was hoping to do the "systemless" root so I could take updates easier. I use ARU Unchained with my Pioneer NEX car stereo to mirror my phone, so I can use all the functions of the phone directly on the NEX. I have a Screen Beam. All works great with my rooted S5. I have not received my 6P yet, but I have a tracking number. Good to know in advance, I guess. Not sure if this is a show stopper for me or not, but I'm sure not happy about it.
I can confirm it works out of the box on a Samsung j series 4k smart tv. I just had to pair with the tv through the wifi direct menu.
I was able to connect using direct WiFi but how do you share screen after that?

I think you need Chromecast in order to simply mirror the screen. But you can actually mirror the content most content that is to most Smart TV's

I don't want to root it, I saw someone posted that it worked by connecting direct wi-fi so was wondering if there is anyway but looks like 2 options are chromecast or rooting unless someone can help suggest connecting using direct wi-fi.

Yes, those are your two options. And if you go Chromecast, you can't start mirroring without a data connection. That was the killer for me, I needed to be able to mirror in remote places with no data signal.
That cast is useless. How can google do that?
