LG UltraFine 5K - Issues/bugs

Yes everyone I've tested has had some form of this. some more noticeable than others. Including a 5K iMac I used previously same exact locations.
But really only on a solid black background.
I've only seen it with a dark black background with corner spots showing light bleed, and with regards to white its either been bright (bluish tint) or warm with a yellow tint but not very bad....
I have a recurring issue where *all* USB devices (disk, audio interface, keyboard) will fail to mount when I connect my MBP to the LG. Pulling and re-inserting each cable then mounts each device. I have two MBPs that I alternate with the LG, not sure if that has anything to do with it.
Just me, seems like?
I have the same issue on my 13" Touchbar model. I found that rather that unplug and plug everything back in, you can just unplug the monitor power from the wall, then plug it back it.... and after that everything seems to connect fine when I connect the USB-C cable.
I only use my MBP as a portable once every couple weeks or so, so it is only a minor annoyance, but if I had to mess with it like this a couple times a day I would not be happy.
Good to know it's not just me.
Also, this one is funny: I like to use the LG display with my laptop closed. When the screen locks after inactivity ... I don't have the option to use my password to log in. Have to open the laptop to use TouchID.

You should be able to just move your pointer using mouse or trackpad and the password box should appear.
I recieved my monitor yesterday and are having the same issue. Just got of the phone with Apple and they would be happy to swap it with a new one, but I'm not sure if that will help anything. Most likely not, I guess...
I really don't want to return it for a refund, I like it a lot apart from this issue.
Just to report that I've been using the 5K since december (first batch).
Sleep wake issue - fixed
Screen brightness lag - fixed
Volume scale - not fixed
Ambient sensor - not fixed
Overall I'm happy with the monitor. Great display quality. I'm not happy that LG/Apple are not active in the product support. 4 months after product shipped I would expect all the issues ironed out. Yet LG hasn't even released a single firmware update. Abysmal product support.

Has anyone been able to mitigate the issues with the microphone dropping out? I cannot last more than 5 minutes on a FaceTime call without my microphone cutting out. I keep switching the audio source from one 5K monitor to the other, but it's about to drive me over the edge.
I just described my recent experience (which isn't too bad) with the display over in the owners thread. But there's one issue, which I didn't come across in any of the discussions here. Since using the display for the last 4 days (since unwrapping it) it happened twice, that I booted the MBP, and the brightness was set to the lowest possible value. First I briefly thought, there was an issue with the backlight, but then I vaguely saw the login and hit the brightness button and could turn the brightness back up. I will have an eye on the behavior, to see, if I find a pattern when it occurs. If it keeps happening, I might ask Apple for an exchange...
Did anybody experience that too?

My brightness sometimes changes itself for no apparent reason too. Sometimes it goes to max, other times min. Another little annoyance sent to test us...
I bought this monitor on the last day it was available for sale and recently took delivery of it. This thing is definitely not an Apple monitor, but OK, I can try to make it work. The picture quality is definitely good, so at least it has that going for it. I absolutely love having only one cable, sounds silly, but this was a big factor in me upgrading.
I'm still considering whether I want to keep it or not due to 3 issues:
I'm still considering whether I want to keep it or not due to 3 issues:
- The well known volume control issue. I find it puzzling that this is still outstanding after the monitor has been out for this long. It seems like it would be trivial to fix.
- The monitor is in my bedroom. At night, at random intervals, I'll notice the monitor turning on for a few seconds and than off again. At first I thought it might be due to notifications, but that doesn't seem to be the case. Is it what people refer to as the sleep/wake issue? I have enabled "Prevent computer from sleeping automatically when display is off" but I did leave Power Nap on, I assumed this was redundant, but maybe that's just what it is
- By default, Touch ID is on. I mostly use it in clamshell mode. I assumed that when in that mode, I would automatically have the option to enter a password, but that doesn't seem to be the case. Ideally, I'd like Touch ID when not attached to the monitor and password when attached.
When presented with the lock screen, just start typing your password - the password field will then appear.
I hate that on the day I took delivery of the monitor, Apple announced they were releasing a new monitor.
If that really bothers you then you can take advantage of the Apple 14 day return window and get a full refund.

It is hard for me to conceive what possessed LG to design a monitor without any hardware controls (e.g. On/off) on the monitor itself. That these fundamental problems remain unaddressed this long after launch and especially after the embarrassment of the inadequate shielding fiasco, is not a good reflection on LG, or Apple.
I think removing hardware controls is actually really nice and for me at least, is a positive design element. I certainly don't miss having one of those terrible display menu systems. However, LG really do need to issue a firmware update to resolve these silly issues as soon as possible. I expect they were tackling the shielding issue in the first instance but that was a hardware issue and the other issues seem more like software issues so you would have thought they could have dealt with them in parallel.
Since using the monitor on 10.12.4 for a couple of weeks, and having performed an SMC reset, a lot of my original issues seem to be have been resolved. USB disconnections don't seem to be happening anymore, random monitor wakes for Power Nap seem to also have stopped. The large cursor doesn't seem to be there any more. Even the general performance seems to have improved (but it still struggles if I'm not using the MBP in clamshell mode, which I'll just have to get used to - annoying since the Touch ID sensor is out of reach then).
What I do have though, is absolutely horrid mouse lag when night shift kicks in (at 22.00). I'm not sure if this just affects me when the LG is connected, but I always have to turn it on and off again.

I have a 13", 4-tb3-ports model and the 5k. I occasionally get high CPU use from kernel_task and console errors related to "invalid display" and another error "Driver reported mode info is out of sync with current mode". In these cases, the kernel_task is gobbling ~50% CPU and the frame rate drops ~4x. It's obvious because of the low frame rate and it's easy to stop the behavior by unplugging the monitor.
If you're an apple engineer & want my spindump or syslog hit me up in direct messages. I'd love to send the info over.

That did the trick thanks! I thought I had done this, but I could have been trying to get the password prompt with the trackpad.

I think if I hadn't also ordered a MacBook Pro 15" to go with it, I would probably just have returned it and soldiered on for a year with my MacBook Air, but as it is, I would also have to return the machine since it wouldn't be practical to use it with my old 27" LED Monitor. I think my best option is to keep it at this point since while the errors are really goofy, the image quality is actually pretty decent and the issues seem fixable.
First world problems, I know, I know.

Agreed, I think it made sense to not include the hardware buttons, especially since Mac users are now used to them and considering this was targeted for Mac users, which makes the volume error and the time it's taking for a fix the more puzzling.
