    Great display that would be even better in an Apple enclosure

    • Written by Neil W from Calgary

    There are inaccuracies in other reviews. First, this is definitely a glossy display, not matte. It is quite reflective, more than the 5K iMac, however the gloss lends itself to a high level of clarity. I haven’t found the gloss to be an issue. I have had no issues with the display waking from sleep. The problems encountered by other reviewers may be from earlier iterations of this display as it seems that this model has quietly been updated since its original release at least once, as has the firmware. The display does wobble though, and I have had instances where accessories connected to the back have “cut out”, including external drives that then eject as a result.

    Overall, it is a terrific display with outstanding image quality. I am disappointed that this display is not sold as an Apple product though as it would look magnificent in a space grey aluminum rather than the black plastic. The display looks a bit tacky in photos and I will say it does look much better in person. I do love the height adjustability, a feature that was missing from earlier Apple displays.

    Not beautiful, but great

    • Written by Philip L from LONDON

    The case is boxy. But the screen is gorgeous and being able to link to a MBP with one cable is brilliant. Highly recommended.

    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)

    Amazing monitor - not perfect but almost

    • Written by Michael R from North Vancouver

    Not sure why everyone seems to hate on this display so much but here's my two cents

    My setup: 2017 15" MacBookPro + 2 of these monitors (wired ethernet + BOSE speakers in one and 3 4TB drives plugged into the other. Make sure you plug one into the top of one side and the other into the top of the other side, you can't plug two into the same side - won't work.

    - absolutely outstanding image quality, clarity (coming from a graphic designer and photographer)
    - good design, like the stand, simple and black - you're looking at the screen anyways, people
    - occasional issues with my BOSE USB Companion 5 speakers when plugging in, sometimes have to unplug and plugin to get them to work
    - CRAZY fast connection (able to get 150mbps on ethernet and full speed on all three HDs plugged in at the same time)
    - controlling brightness on the keyboard only controls one monitor, which is odd but not a big issue for me
    - LOVE the single cable to charge and display

    Overall, I love them not 100% perfect, but way better than everyone is giving them credit for.

    Amazing Monitor!

    • Written by Stuart W from Essendon

    Been using this monitor for a few weeks now, and it's been amazing!
    Haven't had any issues with the monitor to date, LG have been actively fixing the many issues this monitor had on release day.

    Colors are amazing, never seen anything like this in my life. (I believe it's the same panel as a 5K iMac)
    Sound from the monitor is okay, for the price I would expect something better. However, they’re the best speakers I have heard from a monitor.

    Using one cable to power a Macbook Pro and sent a video signal is very convenient when I’m not using the monitor and keeps my desk tidy.

    The monitor I have has minimal IPS glow, which is great!

    However, my gripe I do have is the ambient sensor still has not been enabled / being used. It has been nearly a year since Apple announced this monitor and it is still not able to be used to automatically adjust brightness.

    If you’re having issues with this monitor please update the firmware via LG Screen manager which is found on the LG website. This fixes most of the issues that people were having.

    Best display I have owned.

    • Written by Michael K from sarnia

    Saw in Apple store and could not believe the clarity. The black bezel and stand look fine and the single-cable connection to my MacBook Pro 2016 is clean ands keeps my MBP charged. Brightness and sound levels adjustable from my Magic Keyboard. Sound is adequate for causal use. Final Cut Pro shines with the extra screen space and stunning clarity of images and text. This replaces an older 30” Cinema Display and there is just no comparison. It might not look like an Apple product, but the build-quality, display quality and software have Apple written all over it. I would give 5 stars if the price was a bit lower. Otherwise, very happy with this purchase. Note: I have the most recent version of this monitor with all of the fixes and latest software update from LG.
