Screen mirroring not working with my TV - help

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

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.

How does it work then? I am using wifi not wifi direct so surly all traffic on the wifi network is sent via the router?

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??

Cast screen option in display settings

Hey guys I just noticed yesterday in the display options is an option called cast screen. When pressing this option it says no devices found.
My question is with this option available does this mean I can mirror my tablet to my tv? And if so will chromecast support this or do I need a miracast adaptor?
I have the first nexus 7(2012) model on 4.4.2
Thanks in advance

I have the same question. I noticed this option on my Nexus 5 but not sure if it was there on 4.4 or showed up on 4.4.1 or 4.4.2. Hopefully somebody chimes in.

I tried to get it working with my Netgear PTV3000, but it wouldn't work. I'm assuming it only works with a Chromecast adapter.

Just Google. Android display setting cast screen
....the answer is there...forthcoming screen mirroring for Chromecast.

I read two sources stating that chromecast will soon have screen mirroring but how reliable are the sources? I have ordered one anyway so hopefully mirroring does come to chromecast. Until then I'm happy to view what's available so far

Cast screen works perfectly between Nexus 5 or Nexus 7 and Sony 42W650A... Sometimes, the connection fails while casting but hey, it works
It is supposed to be Miracast. If you have a receiving device that supports it, it should work.

Cast screen isnt only for Chormecast, its for all Miracast devices. I have 2013 Smart Tv from Samsung and SGS4 i9505 with CM11 and still cant get it working. I managed it only one times, and I dont know how :crying: (I had in developer options turned on Wireless display certification, and then in Cast screen option have many more options, but i dont know working combination now)
Anyone can help?

New Cast Screen option (4.4.2) replaces the Wireless Display option which was there (on Moto X) before KK. [Settings/Display/Wireless Display]...
It works on my Nexus 7 2013 to cast to my LG Smart TV 42LN575V....the screen is mirrored perfectly, in Miracast mode, not Chromecast, direct mirror of phone screen on TV.

Cast not working on Vivokat 4.4.2 (Incredible S)
My Incredible S with Vivokat 4.4.2 build #4 can't see my WiFi dongle (T516 from W2Corp). This dongle works with DLNA, Airplay and Miracast. The phone can't see my computer with Airplay server running as well. If I use any application such as iMediaShare or Streambels, Airplay works as it should, both to the computer and to my dongle. I am not fully aware of what Cast ought to support. Is it only Miracast or is it both Miracast, Chromecast and Airplay. Can anyone help clear this and have any good idea on how I get Cast to see my devices?

Did it work with Chromecast? That's the only reason why I want to get one.

Just an fyi for anyone looking at this thread or the OP this is now available after the chromecast update yesterday

I didn't realise this was supposed to be working with the n7 2012, bit it worked for me this evening! Anyone else?

Chromecast Mirroring support didn't work for me on my Nexus 7 2012 that I upgraded to 4.4.4 last night. It does work on my Note 3 phone however and works well.
The google support page says that it has support for the Nexus 7 2013 version though. I don't know anyone that has one though to see if that is true.

The Wireless Display/Cast Screen under Display Settings is MiraCast only. I just tried it with my Chromecast and it doesn't work. You can only mirror your screen to Chromecast by using the latest Chromecast app.
On some devices, screen mirroring is disabled in the Chromecast app, but you can use this app here to enable it

Miracast Support

So it turns out, the Nexus 6P no longer has miracast support which is pretty disappointing since that's how I would mirror my screen in the car, without needing that WiFi hotspot that Chromecast requires.
Does anyone know a way that may be able to get miracast working? Is it a hardware thing or software? Somehow via wifi direct maybe?

You need root and it's a build.prop edit.
persist.debug.wfd.enable=1
Add this line using root explorer or something then save and reboot. Should work. Wireless on my Nexus 6 with Android 6.0

I'm looking to do this. I would be interested to know what screen you use and did it work on N5? (I can't get new nexus til next year )
#WhiteUIMustDie

I just edited my build.prop and now I see the option to enable wireless display. I will test it when I get home from work to see if it actually can see my miracast devices.

So while I have the option to enable wireless display now, I still don't see my miracast devices. Looks like I'm going to need to pick up a chromecast stick
Edit: there was a power dip at my house today and it restarted my miracast device. After restarting, it works!

This works (tested on Rocketfish and Netgear 'cast dongles) but Google apparently did not get the device certified for HDCP. This means any protected stream on your phone will only send the sound. (The video only shows on the phone's screen.) For instance, Netflix won't cast its screen over this connection.
I purchased a Chromecast dongle and it will cast the phone's screen and most content but it too does not support casting HDCP screens. Another extremely critical difference, the Chromecast dongle is not peer to peer like Miracast. It and your phone have to be connected to wireless networks (either the same AP or at least two APs connected to the same network or a network whose clients can route to each other.)
If someone from Google reads this, please offer an update that matches phones that offer Miracast -- Sony, LG, Samsung, HTC and even Blackberry and Microsoft. This is a very handy feature for travelers who can take a carry a small dongle, plug it into a hotel screen and cast videos from their phone.

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:

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?

Chromecast wont work

When I try and cast apps using Chromecast, my V20 will either say it cant connect or connects but doesnt cast anything. This has never been an issue using my other android devices. Anyone else having this issue? Ideas of what might be going on?

Hi there, I just tried it and it worked fine for me.

It works fine with all three of my devices. Try rebooting the Chromecast and rebooting the phone.

Off topic, but no. Chromecast is still Chromecast. The app for it (which itself was never called Chromecast, but rather Google Cast) was redesigned and renamed Google Home with the introduction of Google's Google Home device. The app is now there to serve any "Google" device they release.

On my Sony Android TV the app is called Google Cast that's built in and I can cast from my phone or tablet like you normally would with a Chromecast dongle. It seems Sony broke the ability to cast with a recent update to the TV, which is unfortunate because Sony updates are few and far between. I'll just invest in the new Chromecast and bypass the built in app all together. It isn't the phone after all.

I have the same problem. I rebooted the Chromecast receiver and my LG V20 and it doesnt cast, even to a Chromecast 2.0 device. I tried with my old Galaxy Note 4 and it works fine.
I wonder if this has something to do with Android 7.0 Nougat?

I have h990ds and chromecast 2.0 and everything works well ?

I just got my LG V20 and was having the same issue with Chromecast. One day it would work and then the next not. I found it only works if I have my wifi on my LG set to the 2.4mgz. It will not cast if logged on to the 5mgz. I assume most of us now have dual modems. When in my office my phone goes on the 5mgz. So have to change it to 2.4 to cast. has been working every time so far.

Works like a charm for me, both in ChromeCast and Nexus Player.

I have 3 Chromecast, and 3 Chromecast audio, some on 2.4GHZ, some on 5GHZ and they all work fine using my v20 no matter if it's connected to 2.4GHZ or 5GHZ.

Not an issue with Android 7+. Works perfectly for me and many others. If you're still having trouble try some of the troubleshooting steps mentioned above, like rebooting your v20 and rebooting your ChromeCast. You could first try turning your WiFi on & off, as cycling your data connection often helps with connectivity issues (Either WiFi or carrier, depending on the situation. Though obviously it's Wifi in this scenario)
