Nope. I successfully connected my Nexus 4 to my 55' F6500 last fall. After i updated to Kitkat (vanilla and CM11 tested) screen mirroring stopped working.
Same with my Sony Xperia Tablet Z. Worked with 4.1.2 - stopped working with Kitkat.
It seems liek samsing TV's don't like Kitkat right now.
Allso a Slimport cable will do.

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.

Flashable Build Prop to enable Screen Mirroring ??

Wondering if someone has it to flash on my 6P so that I can Screen Mirror to my Samsung TV's with out needing Chrome Cast .. Thanks
Sent from my Nexus 6P using Tapatalk
You will need to tell us the type of samsung tv it is and what casting it uses natively. As in does it have a app built in that is for casting/mirroring
Without that information we can't really help you to be honest.
Isn't casting native on the nexus ? Settings , display, cast ?
If you want to enable miracast mirroring just add this line to your build.prop
persist.debug.wfd.enable=1

It's a Samsung 5500 series smart TV. And the option on the TV is called Screen Mirroring it worked great with my M9 HTC Connect but with this 6P on my network it doesn't show the TV in Cast..
On the Samsung remote I click Source and the on the TV I scroll over to Screen Mirroring.

Yes I found this out while googling but still if I add the edit I still need to purchase a device to Cast. I'm wanting to Cast directly to the TV to play website videos to it without having to buy cables or another device.
Thx

Have you tried casting to the tv with the modified miracast option?
I use allcast from play store to cast to my Samsung TV

No BC it's my understanding that once I do the Build.prop edit that I still need to buy a device for Miracast to connect to to Cast to my TV..
Unless I'm wrong

Doing the build.prop edit will most likely work for you. Miracast is more of a streaming protocol that most tvs (most samsung tvs) that have screen casting/mirroring built in, use. Your HTC had it by default but the n6p technically does not. But can be easily enabled via the aforementioned build.prop edit.
OK I did the Build.prop edit and now when I open Cast I now have Enable wireless Network which I checked it but still doesn't see the TV ..grrr
I even downloaded AllShare app by clockwork mod and it doesn't see the TV either...
But the kicker is that my wife's Note 3 has AllShare / Mirroring built into it and it doesn't see the TV either on the network..
Surely I don't need internet on the network for it to work ?
It's a att uverse router maybe I orta ditch it and hook up my Belkin gaming router n C if it's the att wireless router causing the issue...

You've tried connecting Mirrorcast with the 6P's Wi-Fi Direct?

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)
