The LG UltraFine 5K Display was compatible and then it wasn't. Will I be able to use it with new 2021 MacBook Pro 14"?
I've spent a lot of time investigating this issue and I can comment on compatibility. There are some... issues.
My Setup
What Does Work
The only way I can get the monitor to establish a connection is by first plugging it in, and then turning on or restarting the MBP.
What Does Not Work
Conclusion
To make sure there was nothing wrong with the monitor, I tested it using my iMac and an Apple Thunderbolt 3 to Thunderbolt 2 adapter and Apple Thunderbolt 2 cable. The monitor worked perfectly at full resolution. It was hot-pluggable and the LG Screen Manager also recognised it and checked for firmware updates, which there were none.
So either LG needs to release a Firmware update for Monterey/M1, or Apple needs to update Monterey, or both need to cooperate. In any case, having to restart my MBP every time I want to plug it into the UltraFine is UltraAnnoying.
Hi Automatt, thank you so much for the feedback. Have you checked if if there are any issue with the usb-c hubs behind the two LG Ultrafine5k? are all of them working while connected to the m1 max? Can you confirm?
I haven't done much testing on the USB3 hubs, but one monitor has both a ethernet adapter connected to it via a USB3 dongle, as well as an SSD drive running Time Machine backups, and everything seems to be working OK.
Thank your for the info. Please keep us updated! Just bought an ultrafine 5k, and new macbook pro coming on Feb. Hopefully the firmware update comes out by then and resolves this issue
Happy to help. There's also a lot of info in this (rather long) thread: https://forums.macrumors.com/threads/lg-ultrafine-5k-owners-thread.2023452/page-103
