External camera laggy - low frame rate

Reply I have this question too (112)

Hi there,

We're having the exact same issue. Hardware:

• LG UltraFine 5K
• 2020 MacBook Pro 13-inch Catalina 10.15.7
  • 4-port, 10th-gen i5 2GHz, 16 GB RAM
  • Intel Iris Plus Graphics

The video lag using the monitor's camera occurs in MS Teams and FaceTime. We have done all suggested Apple troubleshooting (with Apple Support) like going through the SMC reset, reinstalling the OS, trying it on another user account. Does anyone have any suggestions? Would a different system (Mac with different specs) resolve this? What about the I/O and how the systems are connected, any advice?

Same here. Very disappointed.

I did recently speak to someone on support and they gave me the option to return the computer (it was purchased several months ago, well beyond the 2 week window). Makes me assume Apple has no plans on fixing this issue.

LG has repeatedly promised call backs, but I've never reached anyone in their support department that could help with monitors, and I've never received a call back. I've even tried "Share your voice with the LG President" with no luck (see: https://www.lg.com/us/support/email-to-president). At this point I've written off the older 5k Ultrafines ever working.

Dave in SVC, would you mind sharing which 5k Ultrafine you have? The model number is printed under the lower right corner of the monitor. Actually would be great if everyone could do that when posting.

Hi Sean1234, I have an OG, original. 27MD5KA. It says (REV02) after the serial. S/W 3.04.1.13,5237,3.04,0.1e

Hope that helps. Also, I bought my 2020 MacBook Pro 13 in Late May. So I doubt Apple will do anything about it. Even though I bought LG Ultrafine 5K through Apple, based on what I'm reading, I may be stuck with it.

Ok, so after a good start it appears that Big Sur DOES NOT fix the issue.

I just got off the phone with Apple Support. They pointed the finger at LG. I showed them this thread, and explained there were several folks with the same issue... but they still pointed me to LG, who won't fix the issue.

Very frustrating.

Very pleased to report that after months of waiting and a lot of research I have decided to ditch the LG and awaiting a fix from either Apple or LG (and in future any collaboration with Apple) in favour of a monitor that I did much research on. Delivered today. Expensive but not as much as the LG many years ago. Works beautifully (just need to work out the volume on the speakers). The Phillips 329P9H! Note to self.... beware collaborations between two big companies with their own agendas. I am going to get one for work too. Integrated camera, speakers and microphone. Does everything the LG did and does not crash nor need your MacBook to be restarted every time you disconnect and reconnect.

Funny how Apple is finger pointing. That is a sad approach they are taking. There are two management styles when it comes to solving problems; one is to look for a solution, the other is to assign blame. Clearly Apple is choosing the later. I'm a huge Apple fan but will never follow their advice on third party solutions again. They have abandoned loyal customers by not resolving this issue. I wonder if it (the LG) works on the new M1 MacBook Pro 13". Would be very interested to hear from anyone on that. Anyway, thanks @sabitau for the Phillips recommendation. Looks like a nice monitor.

I'm not sure which specific model I have, it was a refurb from Woot, but I just got it about a month ago. Know how I can tell, by serial # or otherwise?

About the same for me, yeah: 2016 13-inch previously and it the camera was fine, new 2020 13-inch is having the issue.

You are welcome.

Excellent. This will help many out there, as they receive more feedback.

Yep - exact same problem here

Keep an eye on the Recall Link everyone - maybe something will popup.

That’s useful info, thanks. Is there a way to disable the AMD GPU at all? Would be very useful to know whether the same Intel graphics crap out on the 16” when the AMD isn’t handling processing.
