I wound up returning it to my job, and getting a different monitor. I got fairly good at locating 1x1px windows and restoring them. It was so slow to wake up that it apparently cycled through several low resolutions in the wake-up-and-connect process, which regularly resulted in all my windows being resized – including to impossible sizes. The issue was the monitor being really slow to wake up when connected to my 2018 MacBook Pro. This included sending it into LG for service, and my laptop into Apple for service. Never had any issues.Ī word of caution: I had a LG 27UK850, through my job, and spent several months trying to make it work right. Would you care to offer any comment on how you think the LG 27UK850-W compares to say a Dell P2721Q? IMHO Dell is an awful company, but their quality screens have in my experience always delivered. I’m not sure I like the stand and I have to admit I really don’t like having to put up with another power brick under my desk for something as large as a screen. So in that sense this LG seems to offer an interesting alternative. OTOH the UltraFine 5K is just too expensive IMHO for those extra pixels. I’m sure the LG UltraFine 4K is nice, but I don’t feel like stepping down to 24' for a whopping $700. Is anyone else having this issue? Between that and now the computer's wifi signal issues I am ready to rethink buying another apple computer.Thanks for that very nice review, in the market for a 4K monitor myself as my trusty old 27' Dell U2717D is just 2560x1440. Upon further research this seems to be a common issue. They couldn't find anything wrong with that other computer. During the second trip to the genius bar the tech mentioned that another mac mini 2018 had come in with the exact same issue. I took it in again for another issue and the tech mentioned that there was another mac mini 2018 brought in with the same issue. The first time they rebooted the system and re-installed Monterey. This has been extremely challenging and I have taken it into the apple store twice now to have it looked at.

Switching back and forth seems to get the computer to recognize the monitor. My understanding is that there are two 'hubs' with two ports being on one and two being on the other. I have noticed that if I unplug the cable and replug it into the other USBC ports on the Mac mini it will sometimes recognize it but it can sometimes take me doing this multiple times. Sometimes when shutting down it displays a green screen. When booting it sometimes works normally and other times doesn't recognize it. After upgrading to Monterey 12.3 the computer no longer consistently recognizes the external monitor. I use a high-quality USBC to DisplayPort cable. External monitor not recognized Monterey 12.3 I have an intel mac mini 2018 that I have been connecting to a 4k monitor since I purchased it.
