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.

I did the same, attached a C920. Other issues I have however include:


  1. USB devices attached to monitor come and go. So my Ethernet and C920 do not reliably get presented to the MBP.
  2. Microphone on LG monitor has poor quality - folks on the other end of my video calls complain.


So I have had to use the LG monitor for monitor only. Speaker, mic, webcam, ethernet all from the MBP or direct-attach to MBP. So the hub concept of the LG monitor is mostly dead. I get video and power through the TB3 cable.

Hi Supermanfan,


Thank you for your workaround suggestion of buying and adding an external webcam. Great idea!


I do want to make sure that we stay focused on the fact that we paid $1,299 for a LG UltraFine 5K monitor with an integrated webcam, which the integrated webcam does not work with the new MacBook Pro 13" 2020. I have three LG UltraFine 5K monitors, so I am extremely frustrated.


I hope this thread will put pressure on Apple to fix the issue as soon as possible.


Thank you,


Aldo

The external webcam was relatively inexpensive (<$100) and actually better than the internal webcam from LG, for both video and audio. So I see it more as an upgrade and for that I am happy. As for the quality of the monitor itself, it remains stunning after three years - no hedonic adaptation here!


As a developer, I have filed a bug report. If you have access to Feedback Assistant, you can refer to FB8002514 and FB7743077.

I have exactly the same problem with an LG UltraFine 5K 27" monitor (purchased August 2020) and a MacBook Air 2020 (purchased July 2020 and running 10.15.6).


I'm running the LG UltraFine 5K 27" display in "default for display" resolution, so this is not a problem related to using "scaled" resolution (which takes more processing power from the MacBook).


Purchasing a separate Logitech webcam is not the solution to this problem (in fact, it creates other problems with having the sound input via the webcam microphone and the sound output via the laptop/screen).


The choppy video doesn't always happen immediately... sometimes it runs fine for 5-10 minutes and then it jams up the whole computer.


Anyway, I purchased this expensive screen so that I would have an all-in-one solution for webcam/microphone/speaker but it simply doesn't work.


Hoping that Apple get a fix on this really soon...

The LG Ultrafine 5k webcam continues to be laggy to the point of unusable on my new MacBook Pro 13" (2020), even after upgrading to MacOS Big Sur. I'm forced to use an external Logitech HD 1080p cam.


It's disappointing that this thread has so many people repeating the same issue with brand new Apple hardware, and there's no solution or response from Apple. LG support is not helpful.
