LG UltraFine 5K monitor 27" webcam choppy working with new MacBook Pro 13" 2020

Hi,

I have two LG UltraFine 5K monitors 27". The integrated webcam in both LG 5K monitors was working as expected (smooth) with MacBook Pros from 2018 and 2019. When connecting a MacBook Pro 2020 to the LG 5K monitors integrated webcam is choppy and freezes constantly.

We have tested the two LG 5K monitors, with 3 different MacBook Pros, from 2019 and two 2020. We can confirm that the issue only happens with the MacBook Pro 2020. We have also tested with FaceTime, Zoom, and Skype and the same issue appears in all apps, so it is not an app issue. The MacBook Pro 2020 webcam works fine with the apps.

There is an issue with the new MacBook Pro 2020 and the integrated webcam in the LG 5K monitors. Does any one have similar configuration and can confirm the problem? Does any one has a work around?

Thank you,

Aldo

I've had multiple second-level chats with Apple Support (I have sent them data via the Capture Data app) and they have stated that the case is known, and they are working on a fix. What's interesting is that they said they have evidence that it is also an issue with the MBP M1's too. Odd right?

It's also more than just webcam performance (stutter, freezing, choppy video, audio) problems. When the MBP Intel is tethered to the LG 5K during Zoom calls, and I am presenting/screensharing from the LG, even when using the webcam on the MBP (and not the LG) poor audio and video streaming occurs on the Zoom (irrespective of the webcam video).

I can't use my LG any longer for Zoom calls that I need to present on (and of course you don't always know when you need to screenshare), I just use the MBP Intel freestanding, which is frustrating, unproductive/disruptive (disconnecting the devices multiple times a day), and not why I purchased the LG 3 years ago.

Hopefully a fix is in the works and will come soon.
