Lenovo ThinkBook 16P Gen 4 - CES 2023 First Look

I'm not sure what the advantage is of this extra feature (that you didn't mention) - it also has a software feature that allows you to merge the video stream of the attachable 4k cam and the regular installed cam. So, whoever is receiving the video signal online (like in a conference call) will only see one moving image - but it will actually be merged live action (of you) from two cams at the same time.
