    Works well....Sometimes

    Occasional it locks up, mouse pointer gets stuck on screen and have to unplug and restart my computer. Overall not great. Hopefully with software upgrades it will get better.

    Great but (sometimes) Glitchy

    Moving from a 2560×1600 display to the 5120×2880 UltraFine 5K is amazing! Although I prefer the 16:10 aspect ratio, it is wonderful to have the retina resolution on a primary display!

    The colors are pretty good (not quite Eizo-level, but better than most). The glossy-finish is a bit annoying, but it's not the most reflective. It's not quite a true 10-bit display (Frame Rate Control is used to create the illusion of 10bit colors with the display's native 8-bit hardware).

    I love how dim you can set the brightness! When working in a dark environment, it's great to be able to drop the brightness all the way down to ~10cd/m^2 (or less)!

    macOS 10.12.4 thankfully fixes the lag when adjusting the display brightness from the keyboard (and, sensibly, removes the need to hold the Control key when hitting the brightness keys on an external keyboard). 10.12.4 also seems to have resolved some performance issues such as the system crashing when Display Mirroring was enabled with the 5K and external displays of other resolutions.

    The webcam is sub-par and angled in the wrong direction – I would rather they have left it off as I use a better-quality external one. (I keep the display at the minimum height and at 90º. However, in that configuration, the top half of my head is above the camera's field of view.) (720p is an acceptable resolution for a webcam, but the aperture is pretty narrow and those 720p images are subpar compared to 720p images from most external webcams which have larger aperture lenses and larger sensors.)

    At the end of the day, working on a 5K retina-class display is a amazing! This is an early adopter's display to be sure, but my list of gripes has been steadily decreasing with each update to macOS 10.12.

    Greate picture quality BUT... does not WORK AT ALL!

    Here's just a short list of my issues with this monitor I am going to return asap:

    - (probability: 60%) When connecting the USB-C cable to MBP, the screen turns on but there is no power, MBP battery does not start to charge. Workaround: disconnecting and reconnecting the cable several times.
    - (probability: 50%) Additionally on the monitor connected peripherals (keyboard and mouse) will not get detected once the USB-C cable is plugged into MBP. The monitor will correctly turn on but peripherals won't work. Workaround: reconnect peripheral cables
    - (probability: every now and then) Screen flickering. The screen shortly flickers 1-2 times, then runs fine again. This happens ~ every 10 minutes.
    - (probability: 10%) When connecting the USB-C cable, the monitor turns on but just with a brightness of ~ 30%, way too dark. It did not recover after reconnecting the cable multiple times. Workaround: Adjust brightness in System Settings -> Monitors

    All-in-all: A completely unstable product! Did LG ever test this thing? Their QA-team must have been on vacation while this product got launched.

    Love this monitor!

    I love this monitor, and it works as advertised right out of the box! Color balanced it for wide gamut, and it's even better. It's amazing having a "Retina" display at this size. I'm a developer and my wife is a photographer, and while we've only had this monitor a short time, it's worked perfectly. Read a lot of negative reviews and was concerned, but my experience has been very positive, and would definitely recommend. Purchased before the price increase, so even better. I've not had issues using with my 13" MBP with TouchBar except a few lags with large images or rapid scrolling. Haven't had much time using with our 15" MBP/TouchBar, but expect to be more than adequate. The aesthetics don't bother me, understanding it's a third party monitor, and doesn't detract from the experience of using the monitor. Yes, the sound could be better, but is fine for iTunes or Spotify, and certainly for FaceTime; a little mushy overall, the highs are not clear, and a little bass heavy, but not nearly as bad as many reviews indicated. The larger 27" screen, 5K resolution, and built-in camera and speakers were the deal makers in choosing this monitor over the smaller 21.5" 4K monitor for me.

    Excellent addition to new MacBook Pro

    I use this display all day at work in my office, along with my 15" MacBook Pro. The build and display quality are very high, and so far (after several weeks) the integration with the Mac has worked flawlessly. I have had no issues, it truly is plug and play. The fact that it is just a single cable to connect to my Mac makes using it that much easier. As with everything else on this display, the speaker quality is Bose-like in terms of crystal clear loudness. It really is amazing all that they were able to pack into this monitor, I can recommend it without reservations.

    Don't let the negative comments discourage you! This thing is INCREDIBLE!

    I was very concerned about purchasing this monitor... and I ended up buying a viewsonic... Which had a nice resolution, but didn't have the Retina display! It was simply not good (color, sharpness, controls, etc.)

    I decided to buy the LG Ultrafine 5K monitor... and let me tell you, this thing ROCKS! The image on the screen is as good if not better than my MBP with Touchbar. The speakers are SPECTACULAR! And the camera is FANTASTIC! The build quality is excellent... and the fact that there are no buttons... everything is managed through the software, it just the FUTURE! TODAY!

    I highly recommend this product. It works beautifully! All the negative comments are from previous version of the product and several software updates ago. They don't apply any more! Works perfectly!!!

    You would think the top of the line display in the Apple Store would work with the "top of the line" desktop in the Apple Store but you would be wrong.

    Nowhere is this incompatibility warned about. When I went to the retail store I even told them I was planning on purchasing both together and no one said anything.

    The upshot is that the Mac Pro is thunderbolt 2 and this display uses thunderbolt 3. The result of using Apple's TB2 -> TB3 adapter, for whatever dumb reason, is that the display must run in 4K instead of 5K. Well, 4K is still pretty good, you might say… but you'd be wrong because a display not run at its native resolution is not as sharp, which kills the whole reason of having a nice Retina quality display with the awesome gamut touted.

    You'd also be wrong because of the next two incompatibilities:

    (1) The display has only ONE thunderbolt port. That's the one you use to connect it to your computer. The rest of the ports are USB-C (not Thunderbolt). So you're not going to be able to connect thunderbolt peripherals to your monitor even if you purchase Apple's Adapter. Nowhere is this incompatibility stated either. I had to spend an hour chatting with Apple support staff before this came up.

    (2) On the Mac Pro, this display will not turn on until the OS is up and running. This means you are not able to access the boot screen, which means you're not going to be able to do things like choose startup disks, Boot Camp, recovery mode, or single user mode, etc.

    Add up all of these factors and it makes this display, which would be a great deal when compared to Dell's 5K display, an overpriced dud. You're better off locating a dedicated 4K display if you want retina-level graphics. Which, I've found, is surprisingly hard to do (LG has a 27" 99% gamut UHD IPS display available but it's selling out everywhere). So, failing that there are other decent sub 4K type displays that are still pretty good in the resolution department.

    Anyway, extremely disappointed they didn't even try to make this work with Mac Pro using two cables, which is supported in theory even if there are no actual displays on the market available to do that with.

    Other than that, it's a VERY NICE DISPLAY (if you have the latest MacBook Pro, is basically the only usable option)

    Horrible! Stay away from this LG Display

    Bought this a few days ago and ended up returning it. I could not stand the problems with this LG Display. From USB not recognizing, to random turn offs, I ended up just returning it back to Apple and buying a used Thunderbolt Display. The picture quality was superb of this display, but the issues were not justified to keep it. This display has many problems and should have never been released to the public.

    Not a great product/New Apple monitors coming in 2018

    First the good- the panel is beautiful to look at. Ok done with the good.I bought 2 of them to hook up to buy 2016 MBP. The biggest problem is they crash my computer 75% of the time it sleeps and/or wakes... requiring a restart. Also crashes frequently when unplugging from the MBP. Not exactly plug and play.

    As a bonus I had to send both monitors in to LG for the shielding issue, so I was without each for 9 days or so.

    But here's the biggest kicker, I assumed Apple was out of the monitor business, that is why I purchased the LG's, however this week Apple announced they will be making stand alone monitors once again starting in 2018.

    Thanks Apple. I love you but this product has been a disaster.

    Unless you need a new monitor right away I would suggest holding out for next year's Apple display.

    Good but not worth the money

    If you're looking at this, chances are you have a 2016 MacBook Pro (or possibly a MacBook), because, well, this is pretty much the only game in town for said computers. And it's a good game. The display is beautiful as you would expect, build quality is sturdy and weighty, sound is decent enough (and very loud if that's your thing), and the single cable to carry everything including a charge is very nice.

    Everything's not rosy though, even after the refreshes. I don't have any issues other people were having prior to the production freeze, but there's still some inconveniences you don't expect out of a $1k 27" screen these days. For instance it advertises itself as a "USB hub," however every other USB must be unplugged then plugged back in after connecting the computer or it just won't register. The connection to the computer itself is fairly tenuous, and only works as expected if you do so when most things, especially things like VM's, are closed and the computer has just started. Try to plug it in before turning it on, or when waking from sleep, or with a VM running, and well, who knows what'll happen.

    It's a solid monitor with a great display, no denying that, but the only way it justifies its price tag is by being the only option for the 2016 MacBook [Pro].

    OK This monitor is in a class by itself. It was amazingly easy to install, plug and play, and the picture quality looks better than anything I have seen. Not a lot of 5K stuff out there at the moment but even stuff shot in 4K is amazing. My standard Sierra 10.12.4 screen saver looks so much better on this monitor than it does on my Mac Book Pro Touch. I could not believe the difference!

    Working like a charm

    Monitor works well with my 2016 15-inch MBP under OSX -> Runs 5k @ 60Hz with no problem.
    The only issue is it only runs 4k @ 60Hz under Windows using Bootcamp.
    My job requires me to work under Windows environment :(
    So Apple/LG/AMD please update your driver or firmware to make the monitor run 5k 60Hz under Windows 10.

    I think I'm returning it.

    The volume problems are definitely not fixed. Going from 1 to 2 is like going from 1 to 6 on any other device. The display also has some pretty bad backlight bleeding. Also my unit suffers from the same sleep/wake issues we have all read about. I bought this display on the last day it was on sale but it doesn't seem to be worth it to me. I'm using it with a 2016 MacBook Pro 15" with touchbar. I really want to like it and recommend it but I can't. I paid 1000 bucks for this, which is a lot of money for me to spend for something i'm not completely satisfied with.

    It works now

    I bought the LG Ultrafine 5k Display with my brand new 15" MacBook Pro with Touchbar, because as it was the case with most other reviewers, it was the only choice for it, and it was "endorsed" by Apple. I received one of the initial units, and was plagued with the same problems others were experiencing (problems waking from sleep, MacBook Pro crashing, etc), so after the announcement was made as of the culprit of these issues, I decided to contact LG directly and get my monitor fixed. Long story short, the process to get warranty service with LG was absolutely painless and very straightforward, but more importantly, the turn around time to get my unit back was exactly 7 days. I was impressed with the service as I am at the image quality and resolution of this unit. Although not in the same league as the Apple Displays in terms of design, choice of materials used to build, etc. the image quality and weight ( if you all can remember the 27" Apple Thunderbolt Display was a Heavy weight in this regards, literally), it is certainly a quality product. Sure, it has some shortcomings such as a lack of bi directional or faster USBc ports, but again, one of the main reasons we buy an external monitor is to be able to replicate the awesomeness of the MBP retina display. Well, this one does not disappoint in that respect.

    problems with waking up from sleep

    I use this monitor with a Late 2013 Mac Pro. Sierra 10.12.4 update has fixed the sound and brightness buttons issue - no more delays. However, I'm still having issues with waking up from sleep: during the 3 weeks that I've been using the monitor, it has failed to wake up twice. I had to disconnect/reconnect power to the monitor or unplug and plug back the USB cable.

    Overall, it's a disappointing experience: I could have picked a cheaper but excellent quality monitor like Dell's 4K P2715Q, but decided to go with Apple recommended UltraFine 5K, hoping that it would work better with Apple hardware and to avoid precisely the issue I'm having: waking up from sleep.

    Broken sound level, broken brightness

    Using with the new rMBP 2016. The sound level is broken like ALL other reviews stated here. 1 bar vs 2 is so vast, that it's either quiet or blasting insanely loud. Don't be fooled, you can't use the built-in speakers on this.

    The brightness is extremely delayed. When you press the brightness on your keyboard, the monitors reacts about 3 seconds later. That means if you press brightness down down down, it will do this for the next 10-20 seconds. If you dared pressed anything else during this time, it will take more time.

    I have no idea how this passed QA. "Just works" is now a bit of a joke. You've been warned. Feel free to buy (like I did, ignoring reviews) then return it when you get to the same issues everyone else here warned you about.

    Terrible software

    Panel is great, speakers appear to be ok. Power supply to laptop works well, but the software is beyond terrible.

    Speaker appears to be accidentally multiplied by ten, because it's too loud to make any sense at the second tick of the mac volume bezel displayed on screen.

    There are countless problems with waking from sleep: USB keyboard not recognized, sometimes the screen doesn't wake up, sometimes the laptop doesn't wake up, sometimes it causes a kernel panic. Occasionally, it will cause the kernel process to consume about 50% CPU and just sit there. I don't know enough to see what files are open, but it doesn't seem to be file-vault related.

    This product is a joint collaboration between apple and LG and the result is terrible. It's an embarrassment.

    Really Great Quality Display

    I've been using this display for about a month now, doing full-time software development (and more).

    If you want top of the line clarity and color quality, this is one of the best options available. There's just not much competition, especially for a Mac. I also used the latest 27" iMac, and this is indistinguishable in display quality. Fonts, especially, are super crisp and smooth--takes a load off when reading, and if you do that all day like I do, that makes a big difference.

    ALL THE PROBLEMS... that people have been complaining about have been fixed. The WiFi interference, the weird big cursor sticking, volume control (mostly), and it preventing wake on the MBP. They all seem resolved in the macOS 10.12.4 update.

    I can definitely recommend it if it's for the new MacBook Pro. If you are okay shelling out the $$$, then it's your best choice for display quality--and the a built-in powered hub, cam, speakers, and mic top it off nicely.

    If you have an older Mac, it's probably still a great display, but you might want to just find a used Thunderbolt display instead.

    If you have a PC, unfortunately that's a big fat NO until/if more PCs adopt Thunderbolt 3 for display and have software to power it. On Tom's Hardware. I can't confirm it at this point. But really, if you have a PC, just get a PC monitor with DisplayPort.

    Not a good display :-(

    As much as I LOVE, LOVE, LOVE Apple products and have always been a long time supporter ; this display is unfortunately junk. It has not met my expectations, and here's why:

    Random USB problems, sudden disconnects, sometimes the built in USB hub works, other times, not.
    Picture quality is just average, I certainly wouldn't say it is worth the cost - $1300 for a non Apple Display , remember, this is simply just a LG display, Apple is only selling the unit, not making it.

    No Apple Care. Can't buy Apple Care because it's not an Apple product. In fact, when there was a problem, I had to send the unit back to LG, not Apple. :-(
