External camera laggy - low frame rate

Getting the same issue after upgrading to a 2020 MBP 13", top of the line. I'm using the LG 4k monitor though, but I suspect since it is a MacOS software problem it's the same thing going on behind the scenes.

I have the most current 13 inch macbook pro with 4 ports connected to the most current model LG Ultrafine 5k monitor. When I use Facetime ot Zoom and switch to the LG monitors camera it is very laggy. I am unable to use. Any update on on this?

In case it's getting drowned out in the ever increasing thread length, I identified the problem (or at least, a likely candidate for it) back in this post:

Please quote Feedback Assistant case reference FB7743077 in any of your correspondence with Apple; so far there are no related cases linked to it.

That's disappointing for you, but actually very useful as an additional data point.

If there is a GPU accelerated application which can use the LG's camera and have the AMD GPU handle it, we can conclusively rule out the issue being specific to the Intel integrated graphics on the CPU, which would actually be a very good thing; it would prove that the issue is software rather than hardware related and therefore no recall is required, only a bug fix.

I feel the more Apple receives notices of this issue it will be fixed. Everyone spread the word the get Apple on it. Seems to be a software patch needed of some sort. It is a Apple collaberated/suggested monitor..not sure how Apple missed this issue, but I am sure they are already on it.

I posted at the beginning of this validating the problem. I’ve following the discussion and share in the frustration of an ongoing problem with no acknowledgement from Apple and no apparent resolution in the works.

That being said, I wanted to share a work around. Reincubate (https://reincubate.com/camo/) has created an app for both the Mac and iOS that allows you to use the high quality camera of your iPhone as a web cam for your Mac. The app is “Camo” and it works great. By using a tripod or mount for your phone, the video quality is superior to the MBP internal camera. Free version worked great on Zoom. Upgrade gives you helpful bells and whistle, but the free version does everything you need for video conferencing. Even if the LG external monitor camera was working, I would be tempted to use this Camo app instead. Just thought I’d share.

But still doesn’t make up for the significant oversight of a current, expensive, high quality, Apple promoted external monitor not working with Apple’s newly released MBP. I’m a longtime user of Apple products but this situation has negatively impacted my confidence in Apple. I’ll continue to follow this discussion in hopes a resolution is found. Any way to get further traction of this issue by having AppleInsider or 9to5Mac or other Apple news outlets and blogs do write ups about this issue?

bkorth nice idea but the software does not seem to work, at least with my MBP13-2020. It does not register that I am connected to my iPhone, either with or without the LG5K connected - though you can see my iPhone is connected.

I probably wasn't clear that you need to download both the iOS app and the Mac OS app. Open apps on computer and iPhone and should work. Just got don't using it for a call. Yes, need a way to hold it and tripod or a mount works great. Good luck!

Strange UX - there is no mention of the need for an iOS companion on their web site landing page. You can find it buried in the 'downloads' page. And - once the connection fails, there is no onboarding or hints to suggest that your iOS version is not installed.

Sorry to complain - I'm a UX designer and this kind of stuff makes me apoplectic.

In addition to the camera of the Ultrafine 5K being extremely laggy on my MBP 2020, I have now problems where the USB devices that are connected to the Ultrafine are often not recognized by my Mac. Replugging the monitor a few times fixes it, but also sometimes leads to a total system crash... Does anybody else have this problem?

Yes. I have LG 5k's at home and office, and computer has to be restarted each time I move from one place to other in order to recognize any USB devices plugged in to monitor. Often crashes just from getting plugged in before I even have chance to restart. I strongly don't recommend updating to latest generation MBP's if you have LG 5k monitors. I'll be downgrading to prior generation as soon as my old computer is back from repair. :-(

Is anyone having this issue with the most recent version of the LG 5k? The 27MD5KL model?

I'm really interested because I recently purchased this model and was planning on getting a new macbook in the near future - my window for return is closing so i need to know what to do. Any help / advice is much appreciated. Thanks!

My model is 3 years old and it works great. I has the camera lag issue with my new MBP13 2020 but rather than wait for a software solution, I solved that by getting a Logitech pro webcam. With a USB A-C adaptor, it just plugs into the USB-C port on my monitor and, from there, connects seamlessly to my MBP through the one Thunderbolt3 port.

Depending on which presentation software you are using, you may have to select a different 'camera.' I had to do this with Zoom though it worked automatically with Meet and Skype.

J Michael - doing the same and it "works", but it's also total BS to be dealing with on a $3k MBP using their recommended $1300 monitor. Support is impossible, so clueless. I asked if they had this logged as a known issue, and rep told me "they don't have a database like that". I'm sure they do, but just don't trust tier 1 support reps enough to let them see it. I'll be downgrading to my old MBP as soon as repair is done, and returning this one. Last support rep said it must just be my machine because Apple has really good QA people. I pointed out this thread, and it was like watching a computer glitch - that Apple might have a bug didn't fit his belief system.
