For Nexus 7 (2013) owners:
Lets discuss <any> working methods for using Display Settings, Wireless Display, on Android 4.3+ with Nexus 7 (2013).
1) I want to explore what happens when Wireless display is turned on - and what it takes for wireless displays to be found.
Fine if you use Google Chromecast, or any other devices as wireless displays.
2) What types of data can be pushed/streamed by "wireless display" - e.g. video, audio, VNC, RDA, files, etc?
You get the idea.

Check this post below. The Netgear PTV3000 works on new Nexus 7 (2013) out of the box.

Good info. Thanks
I *assume* the feature does *something* in Android 4.3+, and maybe *something* specifically on the Nexus 7 (2013).
Of course this assumption might be wrong, e.g. I'm not sure what Wi-Fi, three dots menu, Wi-Fi Direct accomplishes either. LOL
So please inform us if anyone has knowledge of what happens with Wireless Display turned on, or how to make it work.
I'm assuming it's for Miracast. I don't have any Miracast receivers though.
I was hoping it would work with my Apple TV but when I switch on wireless display, it finds nothing.

You are likely correct. I just found this article with some info:
https://en.wikipedia.org/wiki/Miracast
The Wi-Fi Alliance maintains a current list of Miracast-certified devices, both source devices and display devices. The technology and certification is fairly new with the first devices being certified in September 2012. As of January 19, 2013, only just over 100 devices in total were certified.
Nvidia announced support for it in their Tegra 3 platform,[8] and Freescale Semiconductor, Texas Instruments, Qualcomm, Marvell Technology Group and other chip vendors have also announced their plans to support it.[9] Support for Miracast was added to Android in version 4.2 on October 29, 2012.
Both devices (the sender and the receiver) need to be Miracast certified for the technology to work. However, to stream music and movies to a non-certified device there will be Miracast adapters available that plug into HDMI or USB ports.[10]
On 29 October 2012, Google announced that Android version 4.2 (updated version of Jelly Bean) will support the Miracast wireless display standard, and by default will have integrated features for it.[11] As of January 8, 2013, the LG Nexus 4 and Sony's Xperia Z, ZL, T and V officially support the function,[12][13] as does HTC One and Samsung in its Galaxy S III and Galaxy Note II under the moniker AllShare Cast. The Galaxy S4 uses Samsung Link for its implementation.[14]
Microsoft also added support for Miracast in Windows 8.1, and announced this in June 2013. This functionality first became available in the Windows 8.1 Preview, and is available on hardware with supported Miracast drivers from hardware (GPU) manufacturers such as those listed above.

PSA: Nexus 7 and Nexus 10 do not support Miracast wireless display
There’s been an ongoing discussion over on Google’s mobile support forum and after much debate, a Googler took the time to weigh in on the issue confirming:
Just wanted to confirm that Nexus 4 is currently our only Nexus device that works with Miracast wireless display on Android 4.2. There was a reference to wireless display on our Help site for Nexus 10, but we’ve since removed that reference. Our apologies for any confusion that may have caused.

How to connect Google Nexus 4 to PTV3000?
If anyone has the PTV3000 it would be great if you could test on new Nexus 7 (2013) and/or any device running Android 4.3.
The latest firmware update to the PTV3000 is now PTV3000-V2.2.16
From PTV3000_V2.2.16_FW_Release_Notes:
Supported Intel Wireless Display platforms:
Windows 7, Intel Wireless Display V3.1.29.0, Wifi driver V15.1.1
Windows 7, Intel Wireless Display V3.5.41.0, Wif driver V15.3.1
Windows 8 (systems upgraded form Windows 7), Intel Wireless Display V3.5.41.0, Wifi driver V15.3.50
Windows 8 (with Win8 preinstalled), Intel Wireless display, V3.5.41.0, Wifi driver V15.5.7
Windows 8 (with Win8 preinstalled), Intel Wireless display, V4.0.18.0, Wifi driver V15.6.1
Supported Miracast platforms:
Samsung Galaxy S3 (Android 4.1.1 or above)
Samsung Galaxy Note II
Samsung Galaxy Note 10.1
LG Optimus G (Android 4.0.4 or above)
Google Nexus 4 (Android 4.2.1)
Sony Xperia (various models with Android 4.0.4 or above)
Enhancements & Bug Fixes:
Preliminary support for WiDi Gen4 low latency mode. A new option should appear in the WiDi application for prioritizing speed over quality. The “AVSYNC” uboot variable also has new functionality, though it is still currently set to “1”. Change customer_pre_script.sh appropriately if you would like to change the default behavior.
NOTE-1: AVSYNC automatically changes from 1 to 2 when entering “low delay” mode in WiDi, and similarly from 2 to 1 when exiting “low delay” mode.
NOTE-2: Audio is currently not working in low delay mode.
AVSYNC = 0: Disabled.
AVSYNC = 1: Video FW uses Audio PTS for AV sync operation
AVSYNC = 2: Video FW uses STC, System Clock, (ignore audio and decode as fast as possible) for AV sync operation.
AVSYNC = 3: Combined mode. AVSYNC = 1 for DECODER_LATENCY > 75, AVSYNC = 2 in the rest of cases.
Nexus4 Android 4.2.2 compatibility issue – Fixed a rare connection issue related to RTSP.
Improved low power usage for EU region, by suspending to DDR. DC power usage was measured at 290mW. With a 70% efficient A/C adapter it should be around 440mW.
Fixed incorrect setting of decoder latency which was causing video to be early by a couple frames (A/V Sync issue).
Known Issues:
Audio does not work with WiDi 4.x Low Delay mode.
Samsung S3 occasionally does not connect. We are working with QCA on the issue. It appears to be a WiFi driver/firmware bug.
Nexus4 streaming issues:
Phone stops sending data abruptly while streaming high definition video. Air sniffer captures show phone stops sending video packets and goes back to scanning. As result dongle waits for at least 10 seconds for the phone to respond and goes back to ready screen if the phone does not respond.
Samsung Galaxy S3 4.1.1 phone bugs:
Connection will fail if this is done: Start Allshare cast app on phone. Lock the screen and let the phone be idle for 10 minutes. Unlock the screen. Remedy: Toggle WiFi switch on phone settings.
Connection halts after playing a video from Video Player application.
Sony Experia Tsubasa (version 7.0.A.3.185) the mirrored video does not show up until there is activity on the handset screen. Fixed in 9.0.D.1.126.
[Intel] Win8 WiDi 3.5.40.0 application hangs sometimes on reconnection, requiring a laptop re-boot..
Installation Procedure
Push and hold the WPS button on the side of the PTV3000 unit for more than 5 seconds.
PTV3000 goes into firmware update mode. Firmware update procedure shows up on TV screen (also shown below on steps 3 to 7).
Use your PC or mobile device to navigate to http://support.netgear.com/product/PTV3000 to check for and download the latest firmware.
Once you have downloaded the latest firmware zip file, please unzip it and locate the ".sbin" file that it contains.
Using the wireless network manager utility on your device, search for "Push2TV" wireless network name (SSID) and connect.
Open a web browser on your device and type http://192.168.3.1 into the URL bar of the browser.
Follow the steps on the web page to upload the firmware image and complete the installation.
Working Device (Netgear Push2TV PTV3000)
Found a working device. The Netgear Push2TV PTV3000.
Plug the PTV3000 into a mini-USB 5v for power. Connect the HDMI to a TV or monitor. The device displays waiting status.
In new Nexus 7 (2013) go to Settings, Display, Wireless Display. Turn on. Press SEARCH FOR DISPLAYS.
The Push2TV <serial #>-PTV3000 appears in the list of Available Devices. A few seconds after selecting the device the projector shows the entire Nexus 7 (2013) display on the TV or monitor screen.
Note: I took the PTV3000 out of the box and did not apply any firmware updates (yet).
I have lots more questions and things to test. My initial questions are:
1) How does it work with portrait and landscape orientation?
2) Does sound get broadcast to the TV or monitor?
3) Since it works on new Nexus 7 (2013) will it also work on 1st generation Nexus 7 (Android 4.2.1 through 4.3)?
4) How do movies look on the TV?
5) Verify this really Miracast, or is there a second mode on PTV3000?
6) What is the firmware level on PTV3000?
I don't have time to do further tests now. But, ask if you have further questions I can test.
Thanks for the suggestions and help so far... especially gksmithlcw
I tested with this over the weekend and it worked like a dream.
http://www.netgear.com/home/products/hometheater/media-players/PTV3000.aspx
I beg to differ on the PTV 3000
I find it to be useless. It projects an image in the middle of the screen. You could never really watch a movie or anything due to the black bars on the sides. It also does not pass through DTS or Dolby Digital Surround Sound. You are far better off using a media server app like BubbleUPNP to stream media. This is just a little toy. It is light years from being serviceable.

Nexus4 streaming issues:
Phone stops sending data abruptly while streaming high definition video. Air sniffer captures show phone stops sending video packets and goes back to scanning. As result dongle waits for at least 10 seconds for the phone to respond and goes back to ready screen if the phone does not respond.
but with bubbleupnp n7 works well to stream movie, pics or music. so with kitkat widi dosent work. maybe with another kernel and rom??

It scans for Miracast supported device whenit's turn on. If you have a Miracast device connected to the same network, it will show up and you can display your whole screen on the reciever.
Miracast is not Apple's AirPlay and they are totally different. Although they do similar things.
It's also not DLNA. Most of the time files are being sent through DLNA, so you cant see your contacts, messages, homescreen etc. through DLNA. Miracast send your screen feed to the TV.
Miracast need a Miracast sender and reciever to work just like DLNA needs a DLNA server and reciever and AirPlay needs a server and reciever too.
My Nexus 7 (2013) has Wireless Display (I think its Miracast) since 4.3. I think it will work if you have a reciever. I tried it before with Note 2 to my friend's TV which have Miracast support.(I never try it with N7 before because I dont have a reciever). AOSP have support for Miracast as sender since 4.3 (I think)
You need a very fast network to stream smoothly.
The display will change orientation when you rotate your device.
BubbleUPNP is a using DLNA not Miracast.
Miracast still can't work properly in real life.
ALL OF THIS IS ONLY MY THOUGHTS. CORRECT ME IF I'M WRONG
Does anyone else have issues with N7 2013 filling up the screen when connected via miracast? My moto x and N5 fill the screen just fine but the N7 is cropped around the edges.
this device has been working great for me, picked mine up at Wlally-World.
http://www.actiontec.com/303.html#soft
I am also trying to figure out how the miracast feature works or supposed to work with our Nexus 7 2013 model- 5.02 lollipop.
1)My miracast enabled tv (lg model) detects the device.
2)Under cast screen tab in notification panel, tv is not detected but if you enter the more settings options then lg tv is then detected.
3)trying to connect (either from tv menu or nexus menu) results in notification that there is an invitation for connection, then authentication and when the tv shows "miracast is waiting for connection" my nexus stop detecting the lg tv for a few seconds then shows up again but no connection is established. If i insist a couple of times to connect then nexus wifi despite being connected to my home network it cannot connect to the internet.
If someone has an update from miracast feature please post.
cheers
I'd like to use a tablet to display Power Point on a projector. I was thinking of using a Note 10.1 (2014) with a Chromecast installed in the HDMI port of the projector. Has anyone tried this? Did it work well?
Also, when displaying the presentation, can you write on the slides, such as circling or underlining certain words?
Thanks!

I haven't used the Chromecast for this (although with the latest app update, Android screen mirroring should be supported from the Note 2014E), although I have used Samsung's Allshare Cast Hub and Netgear's Push2TV to accomplish this. It works fairly well, provided the devices aren't set up on a network with high traffic.
Slideshow annotation will depend on the app you use to display it, but Hancom and Polaris should both support it.

I teach everyday using projectors. When the battery is low, I use the hdmi output with a cable, so that the device can charge during the lecture. When it's high, I use Netgear's PTV3000 so that I can walk around the students, and stream through wifi.
I have a chromecast at home too, but it works only with selected apps (Netflix and Youtube), and does not work that well: it disappears frequently from the network.
Some people managed to mirror their screens with chromecast, but it was through hacks. Only very recently I heard of it as an official feature, which does not show in my chromecast yet.
In short, if you are out to buy your gear, I'd suggest you to take the PTV3000, because I can confirm to you that it will work well, no matter how you will use it. Chromecast is cheaper, but might crash in the middle of your lecture. It's ok for home use, but for professional use, I'm not that confident.

Do the projectors you connect to have HDMI in, or are you using some king of digital to analogue converter? I also use my 2012 GNote to lecture, but the Allshare cast dongle stopped working with my VGA input only legacy data projectors. I assume this is because Samsung introduced HDCP to the dongle with a firmware update. If the PTV3000 works with ordinary D/A converters then I will get one of these. As it stands I had to purchase a "special" D/A converter that removes the HDCP handshake.
I use the HDMI connection. Have not tried it using a digital converter.
I use Tronsmart T1000 miracast device (it was around 30 EUR delivered) and it works just fine mirroring screen of my Note.
I also have HDMI2VGA adaptor box for the times when I can't connect to HDMI, it works fine and doesn't need any additional power.
Hey guys.
I have an hdmi port in my car which hooks up to my oem display. I also have power next to the port so I can power any 12v device.
I used to use a chrome cast with my HTC M8 but that required a screen casting quick setting as casting through the app was not possible when using mobile Hotspot. The whole setup was also very taxing on the phone, and the chrome cast and mobile Hotspot didn't work well together quite often.
So now with the Note 7, what would be my best option for an hdmi dongle that supports direct screen casting? Should I get a miracast device such as a roku stick? I really don't need any more functionality aside from the screen mirroring feature.
Thanks!

it's a bit old, but is made specifically for Samsung devices and relies on Wi-Fi-direct(no tethering, and no existing network required)
it works using the same system as their smart TV's and is confirmed to still work with the S7 edge, so the note 7 shouldn't have a problem either.
Damn, yeah it is a bit older. Also quite expensive compared to CC or rokustick. I do like that it's wifi-direct though. And there's a quick toggle for that on our phones too.
I know Google dropped Miracast awhile ago, but I really really need it. Chromecast just isn't cutting it. Via build.prop (additions below), I've been able to see the Miracast device but it won't connect. Occasionally I'll even see my homescreen pop up, but it will immediately disconnect. I remember having this problem with an HTC 10 and it had to do with the wifi setting being in battery saver mode. I'm currently unlocked with Magisk on 8.1.0.
Has anyone been successful in getting Miracast to work??
build.prop modifications:
persist.debug.wfd.enable=1
wlan.wfd.hdcp=disable
persist.sys.wfd.virtual=1
I've not heard anyone getting it to work on the Pixel XL 2. Other than I saw this post in the Nitrogen thread here
Just use All Cast. You will need to pay for it, I think it's like $5, but I've been using it for years. Works great and with Chromecast and pretty much anything that allows DLNA. I cast to two TV's, my Nexus Player, XBOX, etc. using it.

This might sound nuts, but is that Chromecast Ultra using a wired network connection? I have no idea the cause but i've had issues with some devices (a samsung tablet for example) connecting to the Chromecast Ultra when it was plugged into the wired connection, often just insta dropping, but it worked flawless when they both were using wireless. Other devices like a Nexus 6p connected perfectly in both network configurations.
Any idea which custom ROMs support Miracast besides Nitrogen OS Oreo? I really need the screen mirroring ability to a windows 10 laptop.
