Hey, do you know what is the difference between the suggested one and https://github.com/Genymobile/scrcpy?
Thanks.

I use a Displaylink monitor and the Displaylink Presenter app to mirror my phone screen onto the monitor. Works well for me. Much more secure than giving a (less secure) PC extensive privileges over the phone by adb/usb debugging.

Its also possible to get Displaylink hubs to which you can connect a monitor

Displaylink presenter uses the casting functionality built into AOSP.

Ive been documenting my experiences over at -

I have casting to Chromecast working. But you need to login to Google

Install the regular Google tools via GOS Apps
Enable Network and Nearby devices for Google Play services and Play store (not sure if this is mandatory)
Install Google Home app.

Login to a Google account is mandatory to get it working.
It works for Netflix and Videoland (mandatory for the wife ;-) Have not tested with apps but it'll probably work.

BTW if you create an empty profile (Settings > System > Multiple users) with only these tools installed, Google only collects the bare minimal.

Why not just install those on your TV?

The security story for TV operating systems is grim. I have a "smart" TV made by a company that was caught deliberately spying on customers. Luckily it has never been connected to a network for even one second.

We have a few older (not smart) TV's which aren't connected to a providers tuner and/or don't have WiFi or LAN.
Chromecast is an ideal solution to get them connected.

Wi-Fi-to-HDMI dongles (e.g., Chromecast) do exist. Connecting a "smart" TV to HDMI is not a large increase in attack surface against the TV. Might the TV compromise the Chromecast over HDMI? In theory, but I'd rather risk that than just connecting the TV to my network. In a sense I'd prefer to trust Google's dongle firmware than the TV's firmware.

I think you missed the point of what I was saying then. The chromecast dongle is "your tv" in this context.

hansaplast You missed the point too. Install it to the chromecast, which IS THE TV.

BalooRJ does this require google play services to be installed? Also, can scrcpy be installed on a raspberry pi?

It does not require Google Play. If the Pi is running Linux, it should work. See the Github for more info.

Update: I can cast from VLC Google Chromecast when the device attached to a TV, but not to VIERA embedded into the TV

I appreciate your efforts in this regard.
I also would like to be able to cast from graphene pixel pro 7 to a Chromecast puck.
The Chromecast does not show, despite being on the same segment of the Wi-Fi, VPN, disabled.

I think I might do better with a remote controlled Linux media TV. Perhaps with its own keyboard and mouse.

sandfish786 Here's what worked for me to cast (assuming you're talking about casting and not screen mirroring):

I created a separate profile in which sandboxed Google play services and play store are installed - but I didn't have to log into Google at all. Using Aurora store I installed the castify app. Using that app, I can cast to my samsung tv.

(Regarding screen mirroring, that I've never been able to figure out, I posted my lament here but so far never got any responses: https://discuss.grapheneos.org/d/10820-bewildered-after-reading-about-screen-mirroring-on-this-forum .)

I found a slightly different way to screen cast / mirror without Play services .
I recently found out pixels support displaylink via USB C .
Plugable displaylink hub here
Using displaylink presenter app which seems ok as it doesn't use the network .
This isn't a cheep solution but it works . add a wireless keyboard and mouse to the hub for a desktop like experience.
