I'm planning to buy a AppRadio 3 headunit for my Jeep, and use the ARLiberator app to unlock it so it mirrors my Z1 on the in-dash screen (I'll provide a link to a YouTube video below for clarification). It mirrors it using an HDMI cable into the back of the headunit (full size HDMI).
This Sony HDMI Cable is what I plan to buy, and do what was stated above, however I've seen mixed reviews on something. The Phone is cradled directly beside the headunit. Does HDMI Mirroring (the basic function, not the ARLibereator app) keep the screen on at all times? Or if I hit the power button on my phone, will it keep mirroring to the "TV"?
The ARLiberator app downscales everything, and transfers touchscreen actions and what not via Bluetooth, and then uses the HDMI Mirroring to show me the screen, as well as charge the phone.

@Wiltron That's a cool idea man.
From my experience if you turn the screen off than you will see a black screen on your receiving device.
Note that this is my experience with miracast but I'm sure that hdmi will work the same way.
Hi,
With my experience with Nexus 10 and Xoom HDMI, the screen will be on until the screen timeout reaches, if you turn off the screen, HDMI will be black too. But there are some apps that can turn the screen black, but still on, like Screen Standby . That's a good idea man.

You can "turn off" yoir display using this app: Screen Standby ♯ Root (sorry I can't link it I'm newbie). Root permissions required

i find it quite annoying when i HDMI mirroring to my TV, the phone itself also remain screen on. is it possible to screen off it without stop hdmi mirroring?
no - mirroring (or cloning) means "the same"
Everything you do and see are the same on both displays - you cannot select one option for the phone screen and another for the external display. They act as one and the same display, not 2 different displays. If you turn of the screen, it does so on both displays. Thats the whole idea and meaning of the term mirroring
The only exception on the O2x are when playing videos - then it actually doesnt do mirroring, but instead swithces to dual display allowing to output 2 individual signals, one to each display - and by doing so it can output the video signal in full HD resolution natively on the external display, while having the phones display showing only the controls in the lower resolution phone display.
But in everything else, the phone only does "mirroring" - and that term simply dictates both by meaning and by technical funtionality of the term that everything are the same.
What you want could offcource be achieved by not using mirroring, but rather only use single display and having an option in the menu to switch between which to display to use (completely bypassing the internal display) - but this option is not available.
So I got my Smart Dock and also have a HD TV adapter from Samsung with the 11 pin adapter tip. Both units act the same. If I plug them in from my home screen the phone locks up with an unresponsive screen and a solid green display on my TV. I have to pull the battery to restore phone functions.However if I load a movie trailer or a YouTube video first and THEN plug in my adapter or dock the "HDMI connected" script comes up on the screen and the TV shows the phone screen the way it should. At that point I can navigate away from the videos to home screen and the display continues to operate properly. Any ideas anyone?? Thanks!!

Ok, so my television is an Emerson. It does not have CEC that I know of. In the settings I don't see an option to disable CEC or anything like it. However, chromecast seems to change the input just fine, although it does not turn the TV on. The problem I'm having is, as long as the chromecast is plugged in, it changes my input. If I decide I'm done casting and change the channel to a regular tv channel, chromecast just changes it right back. Even if its just on the "Ready to Cast" screen. Is there a way of disabling chromecast that I'm not aware of? Or do i actually have to reach behind my tv and unplug it whenever I don't want to cast?
Also, is it good to just leave this thing plugged in and powered up indefinitely? I hear it gets hot after a while.
I got the device when it was released and it hasn't been unplugged for long. Their engineers design for the heat. Min has been on for a few hours and is at 110F. My phone gets hotter during a call. The back of the t If Google thought it was going to catch on fire they would have taped a unplug warning on the device.

So this is my problem, every time I switch from the chromecast to another HDMI port and then I go back to chromecast it takes like a minute to show after all the display flashing https://www.youtube.com/watch?v=V9GYcIZz7gQ&feature=youtube_gdata_player

I had a similar issue with my chromecast, and for me it turned out that my little HDMI cable extender thing it came with was broken. When I connected my chromecast without it, the display feedback went away.
I'm not using the extender, but if I power the chromecast off and on it will show instantly.

It could be that your TV is just having trouble with the HDCP negotiations needed to get the HDMI connection working. My DVD player always takes 10+ seconds to register with my TV over HDMI.
But a faulty cable could be part of it too - a bad HDMI cable may sabotage the HDCP negotiations, resulting in multiple failed attempts.
I've had this issue a couple of times. Turned on Chromcast and it booted ok. The TV shows the wallpaper and then turns to snow, back to the wallpaper then snow again in about the same rate as your video.
Rebooting the chromecast fixes it. While annoying it only happens once every 20+ boots for me.
I use the little HDMI extender, but I don't replug it, just reboot the device itself to get rid of it.

Snow is a symptom of failure of the HDCP decryption - the devices will need to renegotiate the handshake. Rebooting either/both devices should fix it, as will unplug/re-plugging the HDMI connection.
If your Chromecast and TV are both on wall power (ie, Chromecast doesn't get powered down) it should stay synced.
For me it started happening when I switch the image Zoom options to Automatic.
Figured I would post about my issue. I just bought a 2017 Hyundai Elantra. I tried connecting my Galaxy Note 2 to it using the USB cable provided with my phone. Once I run the App, the screen of the car shows nothing but fuzzy white snow (like the old analog TVs showed when there was no reception from the antenna), and then the snow pauses after a second. If I touch the car's screen, it reacts to my input by the snow moving again until I stop touching it.
I was first trying to connect with a CM12 Tesla build (Lollipop). I then flashed my phone with Resurrection Remix 5.6.4 (Marshmallow) and got the same thing. I've tried many tricks I've read from others who had blank screens (not snow, haven't seen anyone report that). I've also played with the Developer options, debug, HDCP and nothing made a difference. I did read that the phone has to be on MTP, but every time I plug it in it switches to USB Charge. If I select MTP after being connected, the screen on my phone refreshes itself (goes totally black for a half second) and goes back to USB charge and the car's stereo goes back to the home screen.
Anyone have any ideas on how to get it to work? Or do I need a new phone?
Same here, have you found any solutions?
