Most "Smart" TVs use Automatic Content Recognition (ACR), essentially taking snapshots every 10+ms of what you watch and hear, then forwarding & selling that data to companies for ads, etc. I now feel it's only a matter of time before this "feature" finds its way to our ever "smarter" PC monitors.

LG with the help of Windows is already installing adware when the right Device ID is detected.

wonder if they could bypass it by laying the ads directly (hardware level) over any screen input haha

They can, they would just need an excuse to make people connect the monitor to the internet to get new ads to be worth the trouble of implementing it.

HDMI and USB C are used in monitors. Both can transmit more than just the image data, e.g. tunneling an Ethernet connection. Not sure if Display Port also supports that

HDMI supports ethernet, but very few devices actually implement it. Even if the monitor and GPU support it, there would be no internet connection unless the PC bridges it to your LAN.

DisplayPort does not carry ethernet.
