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.

Screen mirroring crash

I was trying to screen mirroring to my samsung smart tv, but every time that i try to do it the phone crashes, no response from the screen or or lock buton and after a minute or so it rebots
Does anyone have the same problem? Any help, thanks

I too face the same problem

If someone could port the screen mirroring stock app from samsung mobiles...It would help us...

[Q] Screen On or Off when HDMI Mirroring?

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

Screen timeout

Hi.
I have the following problem when watching long videos such as films, sports etc. on my p30 pro.
Other phones have a feature where they can tell that you are looking at the screen and while you are looking the screen will remain on, however the p30 pro doesn't seem to have this as far as I can tell. At least I am unable to find it if it does.
The maximum setting for the screen timout is 10 minutes. So, if I am watching a long video I actually have to touch the screen every 10 minutes to stop it from turning off!
This is going to get pretty annoying if I can't find a fix.
Is there something I am missing here or does anyone have a workaround?
Thanks in advance.

Try removing the video player you're using from battery management so it doesn't get put to sleep, maybe that will prevent screen timeout

Does your battery saver settings are off?
Settings-Battery-saving mode off (all)
When they are activated there is a leaf in the battery icon.
When it is activated, my screen turns off also automatically while playing games or others and not touching the screen for a while

screen view

Guys, I am new to Samsung phones and I need an answer to a question regarding smart view. When mirroring content from my S10 to my TV, after a few seconds the display on my S10 turns dark and then I get something like an AOD appear on the screen till I press the power key. Is there a way of disabling it, as it just stays in the same position on my S10 display??

Anyone have any ideas?
