[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.

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

Have you modified the build.prop file to make it visible?

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?

Nexus 6P and miracast/mirroring

Does anyone know a way for me to mirror my screen of this phone without WiFi?
The phone apparently does not support HDMI over USB-C and I need to find a way to mirror my screen via HDMI.
My car has an HDMI input to the head unit and it was just recently found to have a bypass in it so that the HDMI will work while driving. I do not want to watch videos while driving but I do want Google maps/waze to be shown on my head unit screen as the car's standard navi is terrible.
I have tried using Chromecast but the Chromecast does not work unless the car is connected to WiFi. Using my phone as a hotspot was a workaround up until an update to the Chromecast was said to cause it to crash. So this option is out.
What I would like to do ideally is buy an HDMI miracast dongle to mirror the screen as it uses WiFi direct. If I go into settings>WiFi>menu>advanced I see the WiFi direct menu but it looks incomplete.
I did some searching and saw that there was a way to edit the build.prop on the nexus 6 to allow for miracast.
Does anyone know if this is possible with the 6p and do you think it would be a viable option?

I have asked the question about the build.prop modification, but have not got any response
I can use TCL_nscreen Pro, but I would like a stock option

It is exactly the same for the Nexus 6 as it was for the 6. There are a couple of threads in here already on it, but essentially it is the build.prop modification and then after a reboot, set the allow wifi setting in the setting of the cast screen.
persist.debug.wfd.enable=1
Chromecast can be made to work again by downgrading to the previous version and then switching off auto update.

You can cast your screen while using the hotspot feature. You have to cast using the cast button in the quick settings. I had to use a tablet to configure the chromecast the first time so it knows what wifi network to use (Which is the hotspot)

Has anyone successfully got this working? I have modified my build.prop without success. Screen mirroring to my Fire stick is essential to me.

Yes, I am using Miracast. As well as modifying the file, have you rebooted and in the cast screen gone into options and selected the wireless option?

It's working now. Thanks

Good to hear

What do you need to add/edit on your build.prop to use Miracast? Just add "persist.debug.wfd.enable=1" ?

Yes. I just added it to the last line.

Will miricast work through apps like YouTube or play movies? Or have they disabled it system wide?

System wide, only casting through Chromecast will work by default.

Chromecast still worked for me. I just switched to Chroma, which has it built in. Pure Nexus did not.

The mic problems I see reported in the thread make me a bit nervous, but it looks like a great ROM otherwise.

Hey guys. I am interested in casting from 6P. I have looked into casting using Chromecast and although i have all the equipment to set up today, I am a bit concerned about the casting dropping out if I were to lose data momentarily (BIG CONCERN). As such, before I install chromecast in my car (using with appradio) only to have to rip it out later, I would like to explore miracast. Can anyone recommend a reasonably priced miracast device I can purchase (say from amazon or wherever) to cast my 6P? I understand its easier to set up and does not require data to mirror.
Thanks

You need a second phone in order to use Chromecast unless you use an older version that lets you trick it into streaming from the same phone that is the WiFI hotspot. Google didn't not include Miracast by default so you need to enable it in the build.prop file. The Microsoft Miracast dongle works fine for me and has been rated pretty well. Regardless, you don't need a data connection for either if you are not streaming something from the internet, so I don't know what you're expecting to be different between the two options.

Wait. I thought that was the main reason why people are opting for using miracast devices and not chromecast. I have the original chromecast (not the newer ones). But I was under the impression that if you lose your data connection (from carrier), your wifi hotspot goes down, and your phone is no longer connected to the chromecast. I am fine not being able to stream content from the internet, as long as my phone is still mirroring to chromecast and is visible on what I have connected chromecast to. I have tons of content on my device that I can cast, I just need to be able to mirror if my data connection on the 6P goes out. Please confirm because this changes everything. Sounds like if I have the original chromecast there is not much difference between it an miracast devices.

I am talking about the Chromecast application that needs to be an old version, not the device. Otherwise, you need a second phone. I don't know if the mobile hotspot dies when you lose 4G even if you aren't using Internet directly, sorry. I didn't think it would, but I've never had the experience to be able to answer affirmatively. Miracast would be your choice if that is what happens, but again you need to edit the build.prop for the Nexus 6P to make it work with Miracast. Dimming the screen is also going to be an issue (the device is AMOLED so screen off programs will not work) in order to maintain a charge, so you should look into that before purchase as well.

LG V20 and Miracast problems

I can't get my LG V20 to connect to any of my Miracast enabled devices. I have a LG WebOS TV and a LG PH150G Projector and can't get either one to connect. On the Projector, the phone will find it just fine, but when it connects the projector will get stick at Signal Detection. On the LG WebOS TV it will just get stuck on connecting. Any solutions?
SOLVED for me at least! It is a conflict with the App 'AllCast' by clockworkMod. Once I uninstalled the app Miracast works!

I had the same problem trying to get the V20 to connect to a Microsoft Wireless Display Adapter. Suggestions would be appreciated!

That's odd. I have a 4k tv with chromecast integrated and also have an ezcast 4k dongle and both of them allow me to use DLNA and also screen mirroring. Currently using Weta Rom.

I think I can solve this one for u. Go into wifi settings and forget your home network(s). Restart phone. Now try to connect to dongle by selecting screen sharing from settings. Let me know. It always works for me

I had trouble with miracast too a few months back. Gave up and just used smart share to watch my movies on my phone. I could look into it again and see if I can figure it out.
Edit.. Just hooked up fine first try. Mines not a webos but it is an lg 3d smart tv.

What version of the phone do you have (Carrier)? I have tried to connect to 4 different TV's and Miracast devices without success.
I just tried using Miracast in 'Safe Mode' and it almost works, The status bar changes to blue, and my projector now gets to starting stream, but eventually disconnects.

T-Mobile. I'm on a custom rom but don't thik that is the issue. Have you factory reset your phone yet? I know no one likes doing that, but might solve your issue. It's definitely the phone though and not your other devices. I know the first time I connect it makes me enter in a code from the tv, but after that it remembers the connection. Try going into your tv menu and see if you can connect from the tv to phone side as opposed to phone to tv.. Should have a menu option for it on all your lg devices that are miracast equipped.
Ok never mind saw you fixed it.

did you guys try to duplicate your fon screen to an external display? if yes, you need to go to the home app on fon n from there you can find to duplicate your screen to an external display which is connected to chrome cast accessory. or else, if you just want without chrome cast device, external display need to be connected to same wifi n either of them should have installed home app so that they can talk to each other.
for wifi printing install printer specific app to your mobile. Make sure that both printer n mobile are on same network (wifi) then it should work flawless.
I have tested all above methods (except smart tv one)
