    2nd monitor works great

    • Written by Jerome F from Hermosa Beach

    The first one I bought on September 2017 worked for 3 months and then decided to never turn on again. I was really annoyed. I took the monitor back to the Apple store, and they replaced it with a new one.
    I've had this second monitor for almost a year, and this one hasn't given me any issues. I plug in my MacBook Pro, and it just turns on every time.
    Maybe the first batch of LG monitors were defective?? Who knows. Just keep your receipt!

    Yes this monitor had issues with sleep mode on a MBP. Finally that is not longer an issue, I'm running 10.14.1 Mohave and all is well. The picture is fabulous . . go look at one then decide . .

    nice display, Apple stands are better

    • Written by Stephen P from Glendale


    Works fine for me. Connected to touchbar Macbook Pro. Great to have the high resolution (I have 5K) screen.

    Vertical position adjustment (a feature which is not important to me, but am including for completeness).


    Wobbles. Whenever I bump my desk, the display wobbles and takes about 6 seconds to damp out and stop. Very annoying. Never had this problem with Apple displays (same desk).

    Horizontal tilt alignment. Yes, you can adjust, but a solid stand would solve the problem with zero user participation. Again, Apple stands are better on this.

    Edge to edge glass Apple display cleaner.

    Heavy. Hard to move from side to side to point screen sideways to adjust pointing or show displayed content to others. Easy to do with Apple displays.


    I held off getting this, waiting for an Apple design alternative, but finally gave up, suspecting Apple/LG arrangements limited customers to this LG version.

    Nice screen display, but wish Apple had continued the Apple display tradition for its superior mount.

    Display wobble continues to be annoying.

    not as "plug and play" as you'd think. Here's how to make it work

    • Written by Kimberly R from Vista

    Once I finally got it working, it seems to work quite well, but I had a heck of a time getting it set up. The "plug and play" feature isn't quite true, there is a key setting you need to configure before it will work properly. I'm sure experienced macophiles would know it intuitively, but it took me quite a while to figure it out.

    When I first plugged it in I was quite frustrated because it displayed my background screen but none of my active windows, and the menu bar at the top of the screen was grayed out.

    I discovered quite by accident that if I set my display to "airstream" to AppleTV it would magically also display on the LG, but that was quite odd and as long as I was using it I couldn't watch Apple TV. Plus there seemed to be a weird delay if I was trying to make a video conference call, as it seemed to be going from my laptop to my appleTV to my monitor.

    In desperation, I started clicking on every option everywhere on my system preferences. I discovered that there is a tab under display called "Arrangement." Under "Arrangement" was a check box under "Mirror Displays."

    Duh. After clicking that, the monitor immediately popped up and all was well.

    I'm sure this was obvious to many people, but to me it was a headscratcher, and even calling Apple Support didn't help, as it didn't occur to any of them, either.

    So, if you buy this, just be aware that plugging it in will not alone make it function. You need to go to System Preferences/Display/Arrangement/Mirror Displays. There are no instructions provided anywhere with the monitor or online either at the apple site or the LG site other than "plug and play," so knowing this is quite helpful.

    Arrangement. Seriously? That's one heck of a non-intuitive command.

    Really great display! Just wish it didn't flicker

    • Written by Jennifer J from Houston

    I purchased the LG UltraFine 5K (27MDKA-B) in ~mid-March of 2018, so I've had it for a while now. It's a gorgeous display, I love the quality and how amazing videos look on this thing.

    My only issue is that my screen flickers. I know this problem was supposed to be fixed but I don't know, I guess I got unlucky or something. Anyway it's still a stunning screen and I'm for the most part happy with it! Maybe one day I'll buy another :) (or go super duper ultra wide, whichever comes first)

    Beautiful picture and better than expected usability.

    • Written by Augustus F from Great Falls

    I'm a seasoned IT professional and I read all the bad reviews and was hesitant. I figured that Apple would not release something defective and rolled the dice.

    I plugged it into my 2018 MBP and it was perfect. Then my WIFI broke and I found I had a lower case network name of my connection. I deleted the lower case network name entry and have had no problems since. Picture is amazing. I think the sound is good. When I put the MBP to sleep it starts up fine. Shutdown your MBP and you will have to open up the MBP to start it up again. All the LG monitor patches were previously installed on the monitor so I did not have to update anything.

    The LG also came with it's own recommended USB C cable and Apple sold me one by default for no reason for $40. LG said to use their cable so I may return the other one.

    I have no new complaints but I'm used to problems.

    Great display, but with minor flaws

    • Written by John T from Fresno

    This display is absolutely beautiful, there's no denying that. I was hesitant to purchase due to all the negative reviews on here, but I have not experienced any of the issues people have written about. User error perhaps? I decided to purchase it because it's the only TB3 monitor that has a glossy display and highest peak brightness of any 5K monitor currently available in it's 27" form factor.

    Here's my current, 100% functioning-as-expected setup: LG 27MD5KA -> Included TB3 Cable -> Elgato TB3 Dock -> Apple TB3 Cable -> 2017 MacBook Pro 15". I also have the LG 4K 22MD4KA connected to my MacBook Pro, in portrait orientation. This non-matching dual display setup is working without hiccup. This setup allows for the "one cable" simplicity that I've wanted, or if I need to use my second LG 22MD4KA monitor, then I just attach a second cable straight from that monitor to my MacBook Pro. I can use this setup in any combination of 27" + 22" + Built-in MacBook Pro display. I typically keep the MacBook Pro in clamshell mode and just utilize the two LG displays. I have no problems just using the single 5K display, or all three displays available to me. This versatility is exactly what I hoped for and expected. I can control display brightness of all three displays using my Logitech Craft keyboard independent of each other by simply clicking on the desktop of the display, and pressing the specific brightness control keys on the keyboard. When I change display setup combinations, MacOS is intelligent enough to remember how the desktop and open windows were set up, and it reverts to that configuration. In MacBook Pro clamshell mode (lid closed) I can sleep the displays, and wake the system up by just tapping any button on my keyboard. My system can go to sleep automatically as programmed, and I can wake it without opening the lid, as well.

    As for the 27MD5KA itself, the flaws I mentioned are:
    1) Ambient Light Sensor is still unsupported through MacOS. After being out for this long and being jointly developed with LG, you'd think Apple's software would enable the use of such a handy feature.
    2) There's no reason a premium monitor like this could not have a stand with a swivel and rotate mechanism. You can adjust the display in the vertical and tilt axes, but that's it. I have it mounted on a fully articulating arm, same with the smaller 4K display so it's not an issue for me but it may be an inconvenience for some.

    To summarize, (and perhaps if you spend top dollar), this display behaves in the usual "it just works" Apple philosophy. I should also note that my 27" monitor firmware did not need updating when I installed the LG Screen Manager software.

    Hopefully I got a good one!

    • Written by Lawrence M from seaview

    So in reading all these reviews quite honestly it freaked me out to even think about buying on of these. So I did the next best thing and bought 1 27" and one 22" of these refurbished by a place in LA. So far I have to say the screen is amazing. I have had every Apple Monitor including a 5k Mac but really liked th eidea of plug and play and I completely get the comments about it not looking Appleish" but as a designer I am super focused on the screen and it is great. I like the telescoping because it really can line up nice. Even put the 22 and 27 on the 15" MBP and it was great. Again it could blow up tomorrow but I really like it. One 27" in the studio is amazing and the 22" for travel is a great size and the box can be carried on a flight. Combine this with the new Wacom Intuos that has has the bluetooth finally working and a trackpad and it is awesome sauce! I would give it 5 stars but all these bad reviews are making me think I might have lucked out? That's it. Happy Branding and Designing!

    Works with older Macs with some limitations

    • Written by Chris T from San Francisco

    FYI, this display does work with the 2013 Mac Pro (as advertised) at reduced resolution and looks pretty good without distracting jagged edges, but it also works with the 1G 2012 MacBook Pro Retina at further reduced resolution (2560x1440). Other models may be compatible at similarly lower resolutions, though it's far from ideal, as text appears noticeably pixelated.

    The build quality leaves something to be desired as the display wobbles left-right if there's any vibration at all transmitted from keyboard to desk. The picture quality is good, with a slight black crush, but excellent color gamut. The audio at moderate volume causes internal parts to vibrate, I wouldn't use this for music playback or any audio-based work.

    There is a reason Apple is getting back into the display business. It's unfortunate that this collaboration didn't work out better.

    Great Clarity but...

    • Written by Ross Y from Aptos

    The monitor's clarity and crispness of text is excellent. However I cannot get the white to match my IMac 5k. Then monitor presents "warmer"colors not matter how I adjust it. Otherwise great and I like only having a single cable to my macbook for the monitor and power.

    Fantastic Image Quality

    • Written by Ryan W from Walker

    The UltraFine 5k is truly spectacular, despite, the many online reviews, I find the build quality to be great. The height adjustment is one of the best features. The often criticized 'chin' is really nothing to worry about in person. The P3 panel is breathtaking. It makes looking at any other display (aside from Apple's own 5k iMac) a waste of good eyes. As a designer, the color accuracy of this panel is truly amazing. I liked it so much, I picked up a second LG 5k! They connect wonderfully to my Late 2016 15" MacBook Pro. The only thing I wish? More connectivity on the back...It would be nice to be able to connect these wonderful displays to my eGPU. Even 4k/mDP ports on the back, in addition to some USB type-A, would have really rounded out this model.

    LG UltraFine 5K Display

    • Written by Mark N from Yonkers

    I tested this with my new 15" MacBook Pro (configured with the absolute top specs for late 2017) and my new Time Capsile 3TB.

    The display works just fine so far, although I have owned it for less than a week. Using the Thunderbolt 3 (USB-C) hub on the back of the monitor, internet downloads were slowed approx. 50% (about 35mb, which is about what you would get on wireless AC), uploads, not so much at all, about 65-75MB vs 80-85MB when plugged directly into the laptop.


    I would love to have had my monitor match my new MacBook Pro!

    Otherwise, its a great monitor.

    Not as bad as these reviews would have you think

    • Written by Kevin J from Malvern

    I've had this displays since it came out and have experienced some of the issues that others have mentioned. After waiting a loooong time to get my hands on the monitor it was a little disappointing out of the box. When I initially setup the display my MBP wouldn't recognize it, but after doing a full reboot it was fine. I think it was more of an issue with my OWC USB-C dock than anything with the monitor. I never encountered the WiFi interference issue, but did have a problem with image retention on the display. The image retention got so bad that it was affecting my work, so I started a support session with LG to get the problem resolved. One quick online chat later and they issued a service request. I received a box to ship my monitor back within a few days and sent it back. I think the repair took a little over a week. My display is perfect now, despite having it returned with a very small crack in a non-visible part of the casing. I'm dealing with LG to resolve that, but it doesn't impact my review of the display, only LG's service team.

    I can see why people are frustrated. This display was flawed when it was initially shipped, but the improvements they've made seem to have helped a ton. The design of the monitor is a bit lacking, but the black bezel seems to disappear when I'm actively using the monitor so I don't mind it. The base is solid and heavy so the display isn't moving anywhere.

    At the end of the day, this is a killer monitor. You can certainly spend less money on LG's 27" 4K display (4K UHD 27UD88-W), but this thing is quality and having the extra pixels is very nice — especially when working in things like Sketch and Illustrator all day.

    * It's 5K
    * USB-C so you only have to deal with one cable to your Mac
    * The color of the display is awesome

    * Would have loved some other connections on the back other than USB-C to avoid buying a dock
    * They probably could have made the bezel smaller, like the 4K UHD 27UD88-W
    * It's a bit expensive, but 5K ain't cheap

    Great monitor - LG needs to fix the firmware

    • Written by Ilias P from Trondheim

    Its beautiful working on this monitor. It is paired with a MBP15 with TB. Some issues at first (March 2017) when waking up etc do not exist any more. After some update everything was fixed (I dont remember when though).
    At home I have a 27 iMac and I use this at work.
    I love that everything is at the same place for a seamless experience when working - but I now I can see pixels on the other monitors, including the one at home.
    - A negative issue is that it gets a bit wobbly depending on the desk which is annoying - especially when you type aggressively.
    -LG's firmware is extremely poor quality, offers nothing and doesn't do what it is supposed to do (known issue until now October 2017)

    Superb clarity and colour

    • Written by Frank M from RUNDLE MALL

    Overall the monitor is fantastic. It is very clear and the colours a very natural. Performance is good.

    I did have some issues with the monitor initially with disconnections of devices attached to it and failing to turn on at times but these issues have all disappeared with the only negative that occurs occasionally is that it will start in a dimmed mode requiring to increase the brightness. I have not determined the sequence that causes this but I use the monitor with my Mid 2014 MacBook Pro 15" with a Thunderbolt 2 to 3 adapter and I believe this has happened when I start the MB and immediately close it.

    I am also using my original Thunderbolt Display (5 years old) which still works very well and I always thought that it was great but having the LG next to it, I can see how much better the LG actually is. The LG is clearer, text is easier to read and the contrast and colours better.

    Deserves more respect

    • Written by Scott F from Atlanta

    I bought this in late March 2017. I was very much predisposed against buying it for aesthetic reasons, but bought it given there were no other 5K MacBook Pro display choices. I heard about the forthcoming Apple displays in time to return it, but did not--who knows when they will ship and what the specs and pricing will be?

    I've ended up really liking this monitor. No, it's not as sexy as a Thunderbolt Display, but it's classier than a typical PC monitor, and three of the four bezels are actually noticeably smaller than the ones on a Thunderbolt Display or iMac, which adds a sort of elegance to it .

    The picture quality is incredible and it works as advertised.

    So, I've been pleasantly surprised with this display and recommend it, even keeping in mind there's an Apple-branded display coming at some point in the future.

    Great but (sometimes) Glitchy

    • Written by William M from Arlington

    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.

    Good but not worth the money

    • Written by Steven F from Marietta

    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].

    It works now

    • Written by LORENZO P from MIAMI

    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.

    Revised version usable but flawed

    • Written by Nicholas E from SAN FRANCISCO

    The addition of WiFi shielding makes this display usable, albeit with a couple caveats:

    1) I crashed my mac when unplugging the monitor while it had its lid closed.
    2) Backlight bleeding/glow is a bit more than I expected, though totally passable.

    On the positive side, the monitor has incredibly vivid colors and it's amazing to have a desktop sized retina display. So, I will be keeping mine. Hopefully Apple can fix the crash and this monitor will be rock solid.
