cast screen help - Nexus 9 Q&A, Help & Troubleshooting

So it seems that I can't cast my screen with my nexus 9 to my smart TV without my Chromecast. That is really very disappointing. Is there any way to cast the screen without using the Chromecast?

[Q] cast screen to my toshiba android tv

Guys want to get my n9 LTE tab screen displayed on my Toshiba android TV.
With my Samsung note 2 the screen mirroring works superb by which I can view my phone screen on the TV whereas with my n9 when I use cast screen in the settings it shows no devices available.
I have installed this app called localcast But still no luck.
Plz help.
Sadly Nexus 9 support screen casting (miracast) to smart tv only if you have Chromecast and configured wifi connection. I'm in same situation,, my nexus can't cast screen to tv only sends videos from YouTube app

Borders left and right when mirroring from Nexus 9?

I wasn't sure if this was just a problem with my device, but I'm running my Nexus 9 on marshmallow and whenever I use the Chromecast to mirror to my TV, there are always borders left and right. This doesn't happen when I'm actually casting video or any apps only when I'm mirroring the Nexus 9 screen. Has anyone else experienced the same issue or can test on their device? Or does anyone know of a solution for this?

The bars are because the N9 has a 4:3 screen, and your TV has a 16:9 screen. Your don't get bars when you cast video because the video plays directly from the internet, not from your N9 screen.
I do recall reading somewhere here on these N9 forums that you can adjust how your screen gets mirrored, but I don't remember if that was just for miracast or also for Chromecast.
I think if you search for CC or MC screen mirroring, you'll find it.

Ah, I found it. It's called SecondScreen

The app requires root, but it works with Chromecast and Miracast.
It sets the resolution of your tablet to match that of your HDTV, so it will completely fill your TV screen. It also let's you adjust the DPI, so text and images don't look so big on your TV.

Screen mirroring through Chromecast or Samsung smart TV problems

Has anyone had any success screen mirroring to either Chromecast or a Samsung smart TV? If so, are you rooted or stock? If rooted, what ROM?
When I try screen mirroring through my Samsung smart TV the video comes through, but the sound does not. When I try through Chromecast, it disconnects immediately when I try to connect.
So...no one can reply after all this time?

I would test, but my 3 year old, in the past week in a half, broke both my chrome cast (not waterproof) and my 55" Sammy (die-cast Lightning McQueen)... My panasonic and LG are both stupid TV's... Sorry I can't help... But I do feel better now that I've vented a little...
I have been able to cast to my Chromecast on both my Sony 46" and my 32" Emerson with no problems. I have an older Chromecast(purchased just 2 weeks before the new ones can't out). Will try mirroring to my Sony when I get home. I can also cast if the Chromecast is connected directly to our Skny home theater system.
I am able to Miracast to my Samsung Smart TV. It occasionally disconnects and has some noticeable delay but otherwise works fairly well. Haven't a Chromecast to test with though. I am rooted with the stock ROM for the record.
no issues here.. try this..
be sure phone is in portrait mode when you initiate screen mirroring. Once connected, than turn landscape. Regarding chromecast, once connected DO NOT use home button 2 escape, just hit back button a few times..

Can't cast to Nvidia Shield TV

I've tried both smart view (which I believe is only for Samsung smart TVs) and Google home app. I'm trying to cast to my Nvidia shield through the Google home app on the tablet. All I get is a blank screen on the tv. Seems like everything is connected. Home app sees the tv and I hit cast to it and the tablet shows that its casting but all I get on the tv is a blank screen. Anyone else having this issue??

I am able to cast via Smartview to my Sony smart TV, Chromecast and Microsoft wireless display adapter on my desktop Monitors. The casting is a little finnicky when my Smart TV is running an app, e.g. YouTube video, otherwise it works fine for me.
Have no luck to do the reverse casting to the tablet via Smartview though.
I'm having issues as well.
Can't cast from my Tab S6 to the Shield.
The screen goes black but nothing happens.
After a while "screen casting has ended" is shown on the tablet.
Casting from my S10 works just fine though.
No idea what's going on.
I am also unable to cast via the google Home app, just black screen then a message saying casting has stopped of something. I can still cast content from the tablet to the Shield such as video from a streaming app,
Connected
I too was having the same exact issue. All was working fine until recently. What I did was used my phone to connect to Shield via smartview. Once connected I opened smartview on the tablet and was able to connect. I only tried once, however I searched rebooted, etc... Still couldn't find a way until today. Good luck I see it's been awhile since last post.
Yep. Also cannot cast screen to my Sony TV - Neither with Smart View nor Google Home. This is either a problem exclusive to the Tablet, Android 9 or root.
My Galaxy S10 can cast to my TV without any issue, running Android 10 and NOT rooted.
What firmware ect is everyone running? I'm on Pie, SK1 and rooted.
Are you guys using a VPN? If so, try disabling it and try again.
