No webcam or microphone in the LG displays. Well the 4k at least. I assume the 5k is the same. It does have speakers. They're ok for the price point but not notable. It's also basically unsupported as far as software is concerned. You can't connect an iPad to it for example. Or at least I can't anymore. Sound would play but not screen mirroring.
Interesting. Thanks for the info. I guess I should have been less lazy and just looked that up before posting. When I was looking at both the 4k and 5k it was completely lost on me that it had those features. Dang! I don't need 5k (or 4k really but w/e) but would have liked to have had the webcam and mic.
