The app is called Vysor from Koushik Dutta and it is in early beta, but I tested in on my Chromebook Pixel 2015 and Nexus 6 and it works. It is not perfect, but I find the app functional. Touchpad and keyboard worked just fine, touchscreen registered taps, but not swipes and multitouch gestures.
How I got it to work:
Note: Root is not required for the android device and developer mode is also not required for ChromeOS.
Enable "Developer Options" on the Android device by pressing the "Build number" in Settings-->About phone a few times.
In "Developer Options" enable "USB debugging" option.
Connect your Android device to the ChromeOS device via USB.
Start the Vysor app on the ChromeOS device. You should be able to select the connected android smartphone from the app.
That it! You should be able to see the android screen on your desktop in ChromeOS.
Not sure who this may help because people hoping to use their second monitor for the app don't seem able to use the app... BUT, there's a new Android app called Vysor by the Clockwork Mod folks that streams your Android device (Lollipop and up I believe) over USB through a Chrome Web App.
You can resize the window and control the app with the keyboard and mouse. I used it briefly last week with the Ground Zeroes app just to check it out. The picture quality drops sometimes (I think this is using some kind of video streaming) but for the companion app it probably won't be too bad. It IS a beta though and people seem to have wildly different experiences with it.
Just wanted to put that out there though since it came to mind!

It runs really well for being in beta, but your input touches will be seconds behind. Still really cool to check out if you're interested.
You also don't need to be rooted
Seems it can get your account banned. I wouldn't chance it until there's something released that Com2us endorses or publicly announces they're OK with. I wonder how they feel about Vysor... It'll let you play on your computer screen but from your android being plugged into it (so you're still eating battery). http://www.vysor.io/
If your device is not rooted then it is impossible for the phone itself to do this. It would be better for you to download scrcpy or Vysor if you're on Windows, and then use a macro/scripting program on your phone through scrcpy/Vysor while it's connected via USB and click on the phone screen that way.
I highly recommend using SteamVR, Zephyr, and Sidesync. With this combo I can get notifications and can use my phone from VR directly. I use it to control my galaxy s7 and it's awesome! I can get notifications, reply to texts, and even make calls using the headset's integrated mic.

If your phone isn't compatible with sidesync you can use Vyzor - http://www.vysor.io
I use Zephyr to get notifications in an overlay in my Odyssey once I'm in steamvr: https://www.reddit.com/r/Vive/comments/4p27c3/zephyr_mirror_android_notifications_to_vr/
It gets me part of the way there. I am able to see the notifications in an overlay in VR, but I couldn't respond to them. With SideSync I am able to respond to texts by just using my mouse on the Desktop view from within steamvr. The audio and voice goes through the computer and not the physical phone.
One thing that people may find useful: When connected via SideSync you should make sure your virtual keyboard still shows up even though it is connected via the computer. This should allow you to text with just mouse clicks using the Vive controller and the desktop view.
To do this click at the top to show the notifications. You should see one that says "Select external keyboard type". You will see an option under "Keyboard Assistance" that says "Show virtual keyboard" that you want to enable.
Try Vysor.
It's an application which runs as a chrome extension. It installs the Vysor app automatically on your phone when you plug it in. Then you can see your phone screen in the Chrome app and control your phone with it.
You might want to check out Vysor if you use Chrome. Personally I've never got it to work (Using Debian and Chromium) well but I like the concept so much I keep trying! I look very easy to setup.
I've never tried it, but maybe you'll have some luck looking into this.
Gives you control of you device in a window on your computer. I'm not sure if you'll be able to control the camera, but it's worth a look.
First off, your title is one question and your post text is asking something completely different.
Can you use a TV on a PC? Sure. A lot of TVs have VGA ports, and even more computers have HDMI ports. Plenty of people hook up an HTPC in their living room to their HDTV.
As far as how that relates to your second question, I have no clue.
If you're really just asking how to cast your Android screen to your PC, then you would just plug a Chromecast into your computer monitor. (assuming it has an HDMI port, otherwise you'll need to buy an adapter)
Even without a Chromecast, you can still get your Android screen on your PC's display by using something like Vysor. It won't be wireless, but you also wouldn't have to buy anything.
Now, we'll also have to ask why you want to even do any of this in the first place. You should know that there's a bit of a delay in packaging up your screen and sending it over the network to the Chromecast, so it's definitely not going to be useful for gaming. For sharing photos and videos on your HDTV, screencasting is pretty nice.
I just started playing around with Mobizen... and it seems like the best solution I've found to remotely control my Note 4 without having root. But looking into it a bit I also share your concerns.
Edit: I stumbled on Visor and I think it works well for me. No need to call back to china servers and you don't need to install anything on the phone. Runs as a Chrome extension and so far it works decently. Not as smooth as Mobizen, but feels a bit more secure.
Yes it is possible. With vysor you can mirror your screen. I've tried it and you will see two pictures, the left and the right eye separated. The quality sucks in the free version. It's much better with the paid one and you can also share the live stream over web.
This Article gives some advice
This is a link to bluestacks which is what i recommend. But i no nothing about how to use it actually.
Brandon Craft uses a samsung phone and there is something that emulates Samsung phones in particular.
Unfortunately this is something out of the current scope of the project as current focus is on improving the notification experience.
As an alternative, you could use a tool like Vysor to mirror your phone to your screen and then use SteamVR's desktop viewer.
What you need is something that also shares the desktop, so that either person can make edits. Something like this https://screenhero.com/
Also, check out Vysor for sharing what is on your device screen http://www.vysor.io/
The Core LTE (G386W) is the Canadian version of the Galaxy Avant (G386T). You can use the same root method as the Avant, instructions here.
As for screen mirroring, what are you trying to mirror it to? If it's your computer, check out Vysor.
I have a Nexus 5 which doesn't have an SD card slot, so I'm not too familiar with managing an SD card on Android, but you can run fsck on Android like this.
There was a update for mobizen on thursday maybe it breaked something. There seems to be a few problems since the update from what i read in the app review since the update.
You might wanna try vysor. Its in beta but i saw jewbagle using it since he also got problems with mobizen.

"Vysor" also can mirror your phone screen to your computer. It requires a chrome extension on the computer side. It is compatible with Windows, Linux and Mac.
Hmm... This is a long shot but perhaps try using something like vysor to control your phone from your computer?
You will need to connect it via USB and already have ADB drivers and USB debugging mode enabled. Like I said... A long shot.
I believe it could be feasible if you VNC from your computer to your tablet, but you'd have to install the VNC server on the tablet first, which could be impossible with the broken screen.
But performance wouldn't be stellar. If you'd like to try easily, give it a try on Vysor.
