[Q] Preferred Wireless Display Adapter?

I recently upgraded my Nexus 7 and saw this in the "What's New" section:
Share what’s on your phone on the big screen.
Android 4.2 allows devices to enable wireless display. You can share movies, YouTube videos, and anything that’s on your screen on an HDTV. Just connect a wireless display adapter to any HDMI-enabled TV to mirror what’s on your screen quickly and easily.

I immediately went to Amazon and looked for different "wireless display adapters" per the announcement above, but I'm totally in the dark to which are going to be compatible with the Nexus 7. Does anyone have a recommendation?
Also, will I be able to connect to my Wi-Fi and still have an internet connection? I'm assuming I will be able to and it's more like they're all networked together (Computer, Display Adapter, Nexus 7, etc.), correct?
Lastly, I don't believe I noticed a new app on my phone to facilitate the connection once the Wireless Display Adapter is purchased and connected; am I missing something?
Thanks in advance for all of your help, you guys are the best!

Start with this thread: http://forum.xda-developers.com/showthread.php?t=1987695 Post 2 & beyond.

Thanks for the direction. Checked that thread out and found that Miracast is not compatible with N7, but is there any other hardware/software that would be?
For example:

The N7 currently does not support Miracast, and there is doubt it ever can since it does not support 802.11a.

ya gotta love it

I have scoured the internet for days and days trying to find the solution to not having hdmi capability and hopefully I'm on the right path. The wireless way sounds like it will be the only possibility so I was reading an article on engadget . Unfortunately I'm unable to post a link to it on here. But if you search nexus 7 WiFi media you will find the article I am referring to.
Any of you more intelligent people have any comments, sounds like a 100 dollar solution. Thanks

That's not screen mirroring. It's just DLNA/UPNP. And there are better and cheaper solutions. First look if your TV already supports DLNA/UPNP. If not, get yourself a raspberry pi and install raspbmc, openelec or any other distro that gives you XBMC. Then just enable it in the XBMC settings and get yourself a xbmc remote and a UPNP/DLNA app like bubbleupnp. That way you can even watch nearly any media you want on your big screen including avi(enable unsupportet mime types in bubbleupnp settings) and youtube videos(in the youtube app just press share and then share it via your xbmc remote).
But it is still no screen mirroring like miracast. I still have hope for miracast on the n7, since MIRACAST DOES NOT NEED 802.11a it is only optional for better performance in some situations.
And if that doesn't work, there is always the amazing open source community. Android Transporter just needs to be implemented into Cyanogenmod and given sound support and we don't need to wait for the big players to implement miracast on our n7.

Look at what asus has to say.

Can you use a Nexus10 as a PRIMARY laptop screen to replace a broken laptop screen ?

I wanted to know if the Nexus 10 can be used as a PRIMARY laptop screen?
A wired connection would be preferred, with a bluetooth connection being an alternative.
I cracked the screen on my Lenovo E420 laptop and I wanted to buy a Nexus10 and use it as a replacement for my primary laptop LCD.
Thank you.

Thanks for posting, Rally.
Unfortunately, the solution you provided requires a Wi-Fi network connection.
I need a wired solution preferably, or bluetooth solution at worst, because I will not always have WiFi access.
From the site you provided:
http://www.celiocorp.com/screenslider_faq
Q: I've installed the PC and Android apps but the two devices can't see each other in the "Find Devices" (PC) or "Connect To" (Android) menus.
A: Make sure that you enable Wi-Fi on your Android device and that the ScreenSlider for Android app is running on your device with the screen turned on,
Q: I've installed the PC and Android apps but the two devices, enabled Wi-Fi on my Android device, but the two devices can't see each other to start a connection.
A: In order for ScreenSlider to function properly both your PC and Android device need to be on the same Local Area Network (LAN and subnet). Your PC can be connected to the network via Wi-Fi or Ethernet but must stay on the same LAN and subnet. This should not be a problem for home use (and for some small businesses too) especially if you only have one wired/wireless router in the home or office connected to your incoming Internet connection (Cable modem, DLS modem, etc.). If your PC and Android device can not see each other on a complicated home network or in an office environment, please ask your IT administrator to see if both devices are on the same LAN and subnet.

But Why??
Why would you use the nexus 10 as a replacement screen when you could just simply well.... buy a replacement screen? Unless your intention is to use the nexus as it is intended as well but..... i don'y know i just find it odd to use a 350 dollar tablet as a replacement LCD.

You answered your own question.
If I have to buy a new "screen", I might as well get one that can serve 2 purposes:
1. A stand alone Android tablet
2. A replacement LCD for my laptop.

As nice and geeky as it sounds, it's never going to be practical. At best you could remote desktop into the laptop from the tablet, otherwise, not worth the effort, just get a new screen, or bin the laptop if you can live with just a tablet.

No problem,
Well, the device isn't designed to accept video on its usb port, and it probably lacks the bandwidth unless it supports some reverse MHL implementation.
As for Bluetooth, I'm pretty sure all Bluetooth versions lack the bandwidth by some margin to display decent quality video at a decent rate.
Unfortunately just the nature of these things, it wasn't designed for it, so it'll never do a very good job of it.... Remote desktop on the other hand over Wifi will probably work quite nicely.

bluetooth completely borked. fix it google!

I've been trying to get a BT mouse to work on my nexus 4.
i've now tried 2 different models, without success.
both are recognized, both pair and then both completely fail to work.
to add insult to injury, i tried one of those mice on a friend's samsung google nexus today -- also running jellybean -- and it worked perfectly.
could anybody running a BT mouse successfully SINCE THE LAST UPDATE (4.2.1) let me know what make/model they have?
EDIT: maybe they heard me ...

i understand your frustration, but just one question.. why are you using a bluetooth mouse on a phone? tablet, understandable but phone?!

take a nexus 4 + slimport adaptor + BT mouse + BT keyboard,
add an lcd TV with hdmi input (now common in hotels etc.),
and you have:
- a portable PC
- a decent home media centre (with armchair remote input)
- possibly a productivity tool for editing text/ photos etc. for which a touchscreen is too inprecise an input device.
understand now?

Instead of doing all that why wouldn't you just go wireless display and then use the phone as the remote at the sametime? Wouldn't that make more sense?
And AFAIK, bluetooth input devices weren't supported?

sorry, i typically use a laptop for those things. It would make a lot more sense btw. You can also use your phone as a bluetooth mouse/keyboard if you have a laptop that connects to a tv.

Wow, you are quite "the absurd man". If you're trying to find help in a forum, it's best if you be a bit nicer. We're both trying to give you better alternatives to what you're trying to accomplish. To answer your questions...
A/wireless display technology is built in with the n4 and jelly bean and it's not yet widely available to most tv's yet but achievable with adapters.
B/so you don't have to carry around a Bluetooth mouse and keyboard. It helps you with 2 less things you carry (unless you're using a combo).
C/this one I can't back him cause I thought it is supported. Maybe it is broken, but I don't use it so I wouldn't know

... perhaps more sense to you, not me.
i don't want to carry a laptop around when i already have a computer in my pocket.
and i'm not happy with touch input devices as they are too slow and lack the precision needed for heavy editing.
these are my (not i.m.o. unreasonable) requirements of the nexus 4.

getting the display to the TV is no problem -- i already have a slimport adaptor! why would i want to max out my wifi for that? it's bananas!
and i've already said that i don't want to use touch input as it's too slow and inprecise for my purposes.
my portable (igo stowaway) keyboard and notebook BT mouse are tiny (and inexpensive).
sorry to seem abrasive but you are not getting what i'm trying to achieve here.

i've heard other people making the tablet/ phone distinction before and i'm not sure it's a valid one. the nexus 4 surely IS a tablet, albeit with a smaller physical (not resolution) screen. what else distinguishes a tablet? i use my N4 in exactly the same way i used my asus transformer and playbook.

In your first post you didn't clarify that you were going to hook it up to a tv, so I assume that you were planning to connect a Bluetooth mouse and keyboard to your n4 and try to work from it's bit-smaller-than 5" display, which is highly unproductive.
N4 is technically a phone, not a tablet, by definition and specifications. I shouldn't have to explain the differences between a phone and a tablet (I'm sure there's a thread with detailed explanations)... just because it's running the same os doesn't mean it has the same hardware classification.
I understand that you want your N4 to replace your computer and the technology is very close, but not quite there yet... For simple tasks, it's good, but for anything editing, a laptop computer is highly more productive than a phone. Imagine you're doing something and you constantly receive phone calls and text messages.
Anyways, I will test this later when I get home and see if it's really broken. I know my Bluetooth moga game controller works just fine so I don't know why your mouse wouldn't.

i'd appreciate that, thanks.
my BT keyboard works fine, but no mouse that i've tried.

Bluetooth is pretty much borked in all versions of Jellybean for all devices. Some things work and some things don't its pretty hit or miss. Version 4.2.1 added some drivers for game controllers but not much else so that's probably why those work and things like mice don't. There is supposed to be another fix coming in the next version but all that's known to be in there for sure is a fix for A2DP streaming.

however, the (jellybean) samsung google nexus has no problem running a BT mouse, as i saw today.
i'd like to raise awareness of this problem with the N4 and get some more response from users, which has so far been sparse, probably because (as other posters in this thread have indicated) few see the need for a mouse.
for instance, somebody reported on another thread that they had been able to make a microsoft 5000 notebook mouse work. can anybody corroborate that?
i'm reluctant to shell out for yet another mouse considering that i'm currently holding 2 non-functioning ones.

not sure how much good it's going to do but i've opened an issue (#43918 Nexus 4 -- bluetooth mouse not working.) with the android development project:
https://code.google.com/p/android/issues/detail?id=43918&thanks=43918&ts=1359688071#makechanges
"bluetooth mouse not working on nexus 4 (jellybean 4.2.1)
i've tried 2 different models of bluetooth mouse. both are detected and pair, and are recognized in settings as input divices, but i get no on-screen cursor nor any mouse/ button input registed by the device. nothing.
the same mice work properly on a samsung google nexus."

i've had one response to my issue at google already.
could anybody else who is having this problem please add to that thread also?
https://code.google.com/p/android/issues/detail?id=43918&thanks=43918&ts=1359688071#makechanges
meanwhile i'm awaiting delivery of a microsoft notebook 5000 BT mouse which has been reported to work by another poster. i'll report back on that when it arrives

UPDATE:
at last i've found a mouse that works!

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?

Good to hear

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

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.

Mirror/cast content from Nvidia Shield TV to Nexus 6p

Hi. This is one of those things that must be so simple, but a Google search just comes up with pages and pages of totally unrelated nonsense. Hoping you guys can help me.
All I want to do is be able to mirror my Nvidia Shield TV to my smartphone screen. Not the phone to the NVidia Shield. Like a PS Remote Play but for the NvS TV. My room is within remote and gamepad range so an on screen pad is not necessary. Any help greatly appreciated.
Thanks
(P.S if anyone knows of any Kodi addons with 4k content...that would be awesome! - there were 2 but they have been discontinued)

Any luck or good leads?
"Allcast reciever"?
What app or apps are you suppose trying to get to your phone?
I've been looking into doing the same thing but to a note 4. I think I found a few ways that seems like they would work for media streaming if your Shield had root access or unrestricted app installation options. Things like allcast reciever and other casting options. They all seemed to have too much latency for gaming if that is what you were wanting to do.
I'm not sure if a chromecast can output audio and video using the HDMI port but that might work if it can do that?
The other issue with pulling this off os that I think the solution needs to be some sort of universal screen and audio mirroring, like googlecast, that doesn't care about what app it is mirroring. Otherwise you'll have to rely on the app that is on the shield being capable of casting, and the Nvidia Hub isn't as far as I know.
I search for terms like: Android to android screen mirroring, android remote display, android remote access, etc....nothing so far.
My most promising hope for doing something like this now are:
1. Making my phone somehow act as or emulate a display, TV, Monitor in a way that can utilize the output from the HDMI port of a SHIELD device. This would bypass all the various issues and complications with specific application capabilities and restrictions, though it is just a idea about how to work around the app issues, I have no idea if this would even be possible. I also don't know if anything that is coming out the HDMI port has any sort of HDCP protection. I would assume that some things would but I would also assume that most of those specific things are the kinds of things. I would just be casting via media players anyway.
2. I have a really REALLY fast LAN network, and I know I am able to remotely access my PC in various ways that are low latency and high performance as far as display and audio are concerned. So, assuming the latency could be kept low enough I have thought about working on getting what I want to access on an Nvidia shield device to my PC running Windows 10, then I can just access that from my phone.
I don't know if you're familiar with that saying about engineering which basically says: "It's not a question of what you want to do but how much you can pay to do it." I say that because there seem to be a couple of fairly good high end Headset based displays out there. One is called the "gylph" or something like that and I have looked fairly thoroughly into one or two others that seemed to be high quality and have reliable reviews and testing available to find online. Some didn't seem available for another year or two, and even then you are going to be dropping $500 to $1,000 for them.
3. Using something like Tridef 3d and a head mounted VR headset based display. I was able to get that working pretty well without too much effort from my PC. The Tri-def software creates a side by side view of the application that you tell it to from your PC. So I can basically get a display output from just about anything on my PC and use it with just about anything they can recieve display output from my PC or remotely view my computers display with low latency. I haven't looked too much to see if something similar to this software is available that can run on a shield device. I would assume they are powerful enough even if you had to scale things down just a little bit.
The kind of set up that could send from your SHIELD, to your PC, to your Head Mounted Display or VR headset could be have some interesting advantages if the overall network latency was low enough. Having the rendering of the initial source on one device and the side by side display conversion on another could have a lot advantages. I own a Samsung gear VR innovator edition headset that I can use with my note 4, but if I want to use it for more than 20 minutes I need to pre-cool my phone in the freezer and to get any significant amount of time I think I would need to develop fairly high performance cooling system. That obviously isn't very easy to do when you need it to interface with a phone you use daily and also be small and light enough to attach to something you're wearing on your face. The point is that doing anything more than receiving and audio and video stream on your phone is going to be very resource intensive for it to handle. Even maxing out the gigabit Wi-Fi on my land for my phone makes it really warm and consumes the battery at a very high rate.
Whatever you do if it is helpful I have connected a pluggable USB 2.0 to Gigabit LAN adapter to the shield portable and it more than doubled the network performance. I'm not sure what the actual LAN performance is on the SHIELD
TV but even if you didn't need to increase it you might be able to reduce latency by by separating the total network load between the internal Gigabit Ethernet port and a separate USB 2.0 or 3.0 lan adapter. I don't know enough about androids capabilities to use more than one network adapter simultaneously four separate purposes to know if that is possible.
Well, congratulations if you've made it this far into my post. I have obviously been exploring this kind of thing for a while but there is a lot potential out there and a lot things that I don't know about or understand thoroughly enough. It's nice to know I'm not completely alone in this specific ambition. Hopefully we can gather a few more people and make some progress with this thread!

...wow
Wow that is an indepth reply. Thanks!
I can tell you've put a lot of thought into this. You obviously have a better chance of pulling it off than I do! (I did read it all lol)
I'm basically wanting to be able to mirror the screen like the PS4 remote play. Not just specific apps.
The only reason I know it's possible is that the Playstation 4 handles it remarkably well. No noticable lag as long as you have a good wifi router. Those guys at Sony must be using some kind of black magic. Unfortunately, I'm not gonna be the one who figures this out. I'm in no way a software or network engineer....I am an electrical engineering student though.
Anyway it's also good for me to hear that I'm not alone here. I wouldn't be surprised if Nvidia were working on this right now or at some point in the near future. And I sold the 6P and bought a Note 5 by the way. Wasn't a fan of the 6P at all.

Anyone get this to work or find another solution?
Thanks
