How is the monitor feeding this data back to the manufacturer if it is connected via HDMI or DisplayPort? From my understanding, these only have low bandwidth reverse communication for control signalling etc, and even if you could repurpose those there would need to be some sort of driver to capture that data and feed it back. Maybe a monitor connected with USB-C could do this.
It’s conceivable that a GPU manufacturer could capture everything you watch with a malicious driver though.
My LG monitor has app to manage it. Haven’t checked egress network activity, but was wondering if that’s how they could screen capture and phone home.
I guess if there is an app then there is a possibility that it could do something. I’m still using an oldish monitor that never had any sort of app.
If it has an app, it's spying on you, it's simply too profitable to not do it. It starts with crash reports and similar useful stuff and soon the MBAs and marketing asshats stuff in ACR ( https://en.wikipedia.org/wiki/Automatic_content_recognition ) and ads soon follow.
The screen can send data via wifi (if it has that) or bounce through your phone if it uses bluetooth.
