The 5K monitor model number and presumably the actual monitor has been updated a couple of times. Any chance the most recently updated design actually has corrected those issues?
I've been researching this for a couple days before this post and am close to pulling the trigger on the LG 5K. The consensus from Googling and Twitter seems like with the M1 and newer at least people are saying the issues have been resolved. I'm still torn though because if they are coming out with a new monitor in the next few months that also has some dedicated graphics processing and better display, that will be really tempting. The resell value of the 5K will go down pretty quickly as a result after purchasing (< 6 months).
How is the contrast and BLB on that panel? The other LG panels in this area seem to have sacrificed basically everything for low reaction times. Also, just one input, and that being Thunderbolt on top, won't work for a lot of people.
Edit: Oh I see, that's one of the LG-but-really-for-Apple-only displays.
Sadly the firmware is flaky, the webcam sucks, it has huge bezels, and is very thick.
Rumor is apple might have a new consumer priced external display next year. Let’s hope it’s true.
