    From a picture standpoint, the monitor is great... when it's working. I have all sorts of problems when connecting to the monitors from my late-2016 15" MacBook Pro. Often the laptop will crash, the monitors won't turn on, or the monitors will turn on with some really nasty flickering that continues for awhile. The only fix seems to be to restart your computer. Also, the monitor often fails to power my Microsoft Sculpt keyboard after awaking from sleep, but that's fixed by unplugging and plugging in my keyboard again.

    DO NOT buy this monitor if you have epilepsy or are sensitive to flashing lights. Almost every day I see something from this monitor that makes me thankful I don't have epilepsy or else I'd be suffering seizures.

    In theory this monitor is great but LG really failed executing.

    Stay away from these monitors

    • Written by Jon T from RICHFIELD

    I have had clients buy these monitors and have worked with 4 of them, and they all exert the same issues:

    - Constant kernel panics when waking up the machine
    - USB ports on the back are not always recognized, requring you to unplug and plug back in whatever USB devices (not a problem if you are using wireless keyboards and mice)
    - Display turns the brightness of the computer all the way down when plugging it in.
    - I've also seen the flickering issue when close to a wifi router, and even the fixed model LG sent us back had the issue.

    While these displays are gorgeous and for some they may work fine, but I've seen issues on all four I've seen, and can not recommend them at all. Too buggy.

    Unstable and poorly tested - avoid like the plague

    • Written by Tony A from Mayfield

    The good:

    - Picture quality (when it works) is amazing!
    - Built-in charging of the 2016 MacBook Pro means less cables
    - …it doesn't look awful

    The bad:

    - Unstable mount means the display wobbles whenever you bump your desk. Or write with a pen. Or walk near it.
    - It makes your Mac unstable. I don't know how this is even a thing, but leaving this display plugged in during macOS updates results in there being no picture, and the software update never completes.
    - It forgets how bright you've set it to be when waking from sleep, or restarting
    - It causes connected USB audio devices lose their volume levels when waking from sleep, or restarting. Mine sets the left output to 100% and the right one to 0%.
    - It's unusable with anything but a MacBook with Thunderbolt 3.
    - The in-build Ambient Light Sensor (used for setting auto brightness) doesn't work, isn't recognised and all mention of it has been removed from Apple and LG's site, despite it being a feature advertised before I bought it.

    Oh! And to boot: the model they shipped out to early adopters like myself is broken (insufficient shielding, and poor connections).

    ***Don't buy this screen. Don't even look at it.***

    I should have returned mine a week into owning it, and now I am stuck with this boat anchor of a display. Nobody is going to buy it from me for anything near what I paid, and while LG say they'll repair the shielding (which leaves me without a display for a week) I have no faith that anything else will get better.

    Apple should never have advertised this display alongside the new MacBook Pro. In my eyes, advertising this display has damaged Apple's reputation, and left me with a piece of hardware that's unreliable and unsellable.

    Sending it back! NOT good!

    • Written by Marry J

    This display has nothing but problems, CANNOT believe that Apple sells this display, I had it for only 3 days and already tons of problems like others have said. Too many problems to even list.

    Very good

    Image quality is above and beyond. Really happy with the performance of this monitor. The only downside is the steep price.

    24 Hours of Frustration - Called FedEx - Goodby!

    • Written by Michael K from Boca Raton

    Received this monitor for our office to use with iMacs.

    Monitor is beautiful but thats where it ends.
    Every time my staff logs off their imac or the machine sleeps, the monitor will not awake upon logging back in.

    What a total waste of a day trying to figure out what the issue is.
    This thing is not merchantable for it's intended use.

    Buggy and unreliable

    • Written by Ink G from London

    LG clearly didn't spend the time they should have done to get it right. Half the time it won't turn on with the laptop (MBP15"2016) and I either have to reboot or unplug the Mac, the USB ports don't always work either, and sometimes the screen comes on with no brightness.
    While some of this could be macOS related I suspect most is to do with poorly written firmware in the LG monitor.
    I also have a cluster of dead pixels which is very annoying.
    Finally, I have found no way of getting this monitor to work with Windows 10 on BootCamp. It just does not work! (I work in IT and have tried everything.)

    works as expected

    I bought the display in March 2017 and have been using it with MBP 15 mid 2014 (connected via a conversion cable USB-C to Thunderbolt) without a glitch ever since.

    Does not work reliable

    • Written by Guido H from Kuhstorf

    I have problems getting the display back after wake-up of my MacBook Pro 13" with touch bar. I have to plugin in and -out connection resetting all connected devices to the monitor, interrupting TimeMachine backup disks and so on ...
    Furthermore sometimes I have a short flickering of the image, that is very strange and last but not least the system 13" Macbook i7 16 GB RAM and LG Ultrafine 5K is really slow. Switching Desktops or even windows takes a while to long to support fast work.

    I really regret, that I bought this monitor for almost 1400 €.

    Pretty but not functional

    • Written by Sterling C from Ogden

    First things first, the display looks gorgeous. Both the design and the quality of the picture are great. However, this display does NOT function well with a mac. Around 20% of the time, disconnecting or connecting my brand new MacBook Pro will completely bring my system to a halt. The screen(s) will glitch and you will be forced to restart your computer. DO NOT BUY.

    Very problematic Display

    • Written by Raj S

    This Display has caused me nothing but grief. I got the revised one sold in Apple Stores and its having all kinds of problems. I have never had so many problems with a display, ever. Especially one that Apple endorses.

    From random power on/off/blackness, to USB connectivity problems, to just LG bad support. I wish Apple would start making displays again because the Thunderbolt Display was the best. This one is horrid.

    Stunning display

    • Written by Evan G from Menlo park

    You know, I don't know why there are so many low reviews of this thing. The price is high, but aside from that, it really is the perfect monitor if you have the new MacBook Pros. It's awesome hooking up just one cable. The speakers on this monitor are superb for a monitor, and it has a built-in mic and camera.

    And the screen resolution/quality has been amazing. I couldn't find anything else with all of those features on the market today. I've been loving the 5K, personally.

    Reliability Problems Persist - Blank Screen, Screen Brightness (Continued)

    • Written by Stephen G from Ashburn

    So many problems with the monitor. It just doesn't work reliably. It is better than it was back when I purchased; but patches fixing their numerous defects aren't being released fast enough.

    I am also annoyed that it isn't compatible with my AppleTV (the product review never said it was). Limits my ability to do presentations in my office.

    Faulty and neither Genius Bar nor LG can correct!

    • Written by P J G B from CAMBRIDGE

    Display is fine, but the hub will not start up with a disk which works fine directly in my MacBook Pro. The Genius Bar could not get it to work – neither would another LG 5K Display tested – and LG technical support simply want to blame the disk, ignoring that it works with the MacBook and also on unplugging and replugging.
    I had to exercise my Sale of Goods rights to return it, as it does not do what is stated.

    This monitor STILL has problems (after "fix" from LG)

    • Written by Christina W

    Just picked up the revised LG Ultrafine 5K display , and this one still has a LOT of issues. I made sure it was the "fixed" version, which it is, but certainly not fixed.

    As many of you know, this monitor was recalled due to cabling problems. Anyway, I can certainly attest to this monitor still having problems and bugs. Randomly, the monitor will auto-shut off on its own, black screens, and kernel panics are all very common with this monitor. I upgraded from an Apple Thunderbolt Display, and ended up just going back to it, because it was Apple and tried and true.

    "Fixed" version still riddled with problems

    • Written by Justin S from Canadensis

    Despite having a "fixed" model (SN beginning with 703) each time I use the display with my 15" TB MBP I have to unplug the display and plug it back in to get it to work, but then the USB-C ports on the back don't work, so I have to unplug it again. It often takes 5-10 minutes of fidgeting with it just to get it to start working. After that I can use it for an extended period but it'll sometimes flicker off for a few seconds and come back on, or just flicker off and not come back, leading me to repeat the 5-10 minute "plugging in" procedure. I bought this for the promise of a single cable solution. This is far from it.

    Brightness constantly drops to zero on wake

    • Written by Michael C from Newark

    Although the monitor looks great and has good color, it's brightness drops to zero whenever I wake my MacBook Pro (2013). The backlight is completely off, although the faint image of the desktop is still there. This means that now my wake up sequence involves opening the Displays system prefs panel, squinting as I move the mouse around the darkened screen trying to locate the brightness slider, then sliding it all the way back up again. It's tedious. It shouldn't happen, and it negatively impacts my productivity. Hopefully this is something Apple can fix from it's end fairly quickly.

    Beautiful display. Works perfectly. No issues whatsoever!

    • Written by Dmitriy G from Rockville

    Bought this monitor despite the bad reviews since the RF issues have been fixed and the bulk of the bad reviews spawned from that. I've been using it for about a week now with zero issues. I have it connected to my 2016 MacBook Pro 13" with a touchbar via the thunderbolt cable that came with the monitor. No wake up issues, works great as a hub ( I don't care about the slower speeds ), fantastic image quality and the brightness is simply amazing. 500 nits just like my retina MBP display so the transition is seamless. I am glad that I pulled the trigger and didn't let the bad reviews dissuade me. I will say that the people that applaud the speakers have not heard decent speakers. Sure, they are better than my MacBook Pro speakers, but I wouldn't call these speakers good (loud doesn't equal good...) I am using Audio Engine A2+ hooked up to the back of the monitor and they sound amazing.

    Defective Display, buyer beware

    • Written by Jenn M

    I bought this display just a month ago and goodness, it has problems. The problems start by everything I plug in USB, does not recognize, to random screen blankness. Sometimes, at random, the screen will just go black. I called LG and they have no solution. This is not an Apple branded display, yet sold by Apple, so I trusted that it would be good. It clearly, clearly, has issues.

    Beautiful but defective monitor.

    • Written by Douglas H from Brandon

    The display is very beautiful and easy on my eyes. The idea of having a USB-3C bus where I leave my backup drives and other devices plugged in and just have to plug in my laptop is a great idea. The problem with this picture is that my unit is defective. It hangs my Mac sometimes when I plug it in or when Night Shift kicks in. It sometimes comes up with a super dim display with no way to increase the brightness in a well lit room. The USB bus fails and requires me to disconnect my devices and reconnect them to get the ports functional again.

    So the question is "Is this a defective unit or a defective product?" The jury is still out, but LG says that my unit functions as expected after I confirmed the problem in the Apple Store with a floor model and after I shipped it back to LG three times for repairs. I hope your mileage is better than mine. Oh and by the way, my monitor got the extra shielding the first time they repaired it, so the original WiFi bug that was affecting everyone was not my problem.
