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

Me too! How can we raise the awareness to apple about this? I'm thinking an issue with the thunderbolt integration on the new MacBook pros. I have read they route directly to the CPU rather than through a controller? Something like that. Anyway, my 5k screen worked perfect with older MacBooks and continues to do so - it's definitely the new MacBook!

I have the same problem with a brand new UltraFine 5K Monitor (2020) and brand MacBook Air 13" (2020) running Catalina 10.15.6

I spent extra money on this screen to get the integrated camera/mic/speakers (rather than using an external webcam, etc) and so I really do hope this is a software fix...

Anyway, just confirming another person with the same problem here...

I'm having the exact same issue. For the past 4 years, I ran a 13" 2016 Macbook Pro and connected it to my LG Ultrafine 27" 5k monitor. The webcam worked perfectly. Exactly same frame rate on both my Macbook webcam as the external monitor's webcam.

Last week, I upgraded to the 2020 Macbook, and the Macbook's webcam works fine. However, the LG Ultrafine's webcam is now essentially unusable. It's incredibly choppy.

Would really like to prioritize a fix for this. I spent a lot of money on this monitor, recommended by Apple, and I shouldn't have to buy an external webcam to make this work like it used to.

I don't have a new MacBook Pro, but I can confirm that the issue also exists with a new Dell XPS laptop. Yes, it works for beautiful 5k resolution on Windows! Bummer that the webcam is choppy And Flutters. I found this board searching for Windows drivers due to the choppy video feed.

I've got the same problem. Upgraded from a 2016 13" MBP to a 2020 13"MBP and the problem started. Worked perfect with the 2016 model. Seems to be a driver issue that needs to be resolved for the new model. I upgraded to Big Sur on both the 2016 and 2020 MBP but the issue remains with the 2020 model. Hope they get this fixed once Big Sur is released to the public because this is really poor for video conferencing.

I just upgraded from a 2016 MBP 15" to a 2020 MBP 13" and am having the exact same issue. This is deeply frustrating. I have the LG 5k display, and if I use the built in webcam on a Zoom, FaceTime or any other video chat, my video is super choppy and will occasionally freeze. I do not want to buy an external webcam. It is crazy to me that a laptop that is 4 years newer would have this problem. You shouldn't need a dedicated GPU for smooth webcam video.

I'm using 10.5.6.

I too started this year with a new MacBook Pro 2020 and just recently got a brand new LG 5K monitor so I could finally have a good work space setup but - the only time I got the LG camera to even start was with Photo Booth, one pic taken and then it froze never to start again. For all applications it basically says "camera is starting" and the camera view is completely black. The green light is turned on though, indicating the camera is on.

I tried turning it off and on again, changing USB outlet, installed latest Big Sur on the Mac, used a sudo killall command and have now run out of black magic to try. Great screen, but would be nice to have a working webcam/integration to MacBook 13" 2020.

Same issue here with an 3 year old LG 5K and a new Intel MBP. It worked well with my old one now I'm forced to use the MBP Cam. If I would install a external webcam and connect it to the monitor would that work better? Any experiences?

Is this confirmed? Are they both on the same OS? Big Sur?

I just got a good condition used Ultrafine 5K, the older A-B version, and have this exact same problem with my 2020 MBP 13" with 4 Thunderbolt Ports. Super frustrating, slow webcam performance. I'm currently still on Catalina. I want to go to Big Sur and M1 but we're in the middle of a big project and I can't easily risk downtime.

Happy 2021 everybody! This thread is the gift that keeps on giving. I can also confirm the M1 MacBook Air works with the LG UltraFine 27". I picked up the base model M1 (MacBook Air (M1, 2020), 8GB, Big Sur 11.2). Zoom and FaceTime are both fine. Auto brightness is unfortunately not working with the LG (never has on any Mac). Maybe Apple can add that in the M2 chip in a few more years. It's pretty wild that a $1k Mac that costs less than an iPhone can drive the 5K LG monitor in 2021.

Having the same issue, tried 2x 5K LG monitors and 2x 2020 MBPs, all combinations have the same issue. All updates installed but no improvement.

I have a 13" 2020 MBP running both a LG4k & LG5k and the webcam on the 5K works perfectly - the 5K is connected via a Blackmagic eGPU, the 4K directly to the MBP.

Regards

I have 2x LG5Ks, one connected to 2020 13" MBP and one connected via Blackmagic eGPU. Both screens have the same choppy webcam issue.

I'm on 10.15.7 and I still have the same issue of lag
