    Buy the newer version LG part number 27MD5KB-B not 27MD5KA

    • Written by Mark H from Roswell

    After extensive research it appears the issues are related to the first generation of this display which is part number 27MD5KA. LG has since rectified the issues and the updated monitor part number is 27MD5KB-B. I purchased the newer 27MD5KB-B for use with my 2017 MacBook Pro and it has work flawlessly. It's a gorgeous display that got off on the wrong foot.

    problems resolved?

    • Written by Tim F from Palm Springs

    I've had my 27" LG Ultrafine 5K Display for almost 8 weeks now, using it with my MacBook Pro 15". I've been mindful of the problems reported in the reviews here. To date, I haven't experienced or noticed any of them. Perhaps LG has been paying attention and making improvements accordingly? For what it's worth, my experiences have been nothing less than those advertised by Apple/LG. The display has lived up to my needs and expectations. No regrets with this expensive purchase.

    Love it! almost did not buy it, but I'm glad I did!

    • Written by Cesar C. E from Randolph

    I almost did not buy this monitor based on the negative reviews I have read on this site, but decided to give it a try, because I really needed a large desk monitor for my 15" MacBook Pro (2016). Just got it a few days ago, and everything works very well! sleep, reconnecting, volume, etc. Make sure you install the LG screen manager, which also allows you to update the monitor's firmware. And yes, the image quality (THE most important quality) is fabulous. Very happy with it. I only use one monitor, and connect via the supplied Thunderbolt 3 cable. Make sure you plug it in the correct port (it is marked)!

    I'd been wanting two of these monitors for some time, but the reviews had put me off. I have a new 15" MBP with touch bar, and I use disk encryption, so based on the previous reviews I'd read this was a recipe for disaster with regards to running these monitors.

    Prior to getting my new MBP, I had a 2013 MBP and when at home used it with a single 24" monitor via HDMI cable. This was great until I upgraded to El Capitan and from this point I had nothing but trouble running any external monitor or projector - and things were even worse when using with Parallels. To my dismay, these issues continued with the new 2016 MBP with touch bar.

    After reading about the issues people had been having with these monitors, I decided to wait given the price of one let alone two. Once LG formally announced they had issues and that new models built from Feb would have extra shielding, I decided I would bite the bullet and buy two once the new stock arrived. After having to wait for around 8 weeks, they arrived last week.

    As many people have said, the quality of the picture on the monitor is outstanding. I haven't had any issues with them when the laptop goes to sleep - everything wakes up again and returns to the state is was in before it went to sleep. I read somewhere that someone who had disk encryption switched on had issues until they switched this off - I still have this on and it's not caused me any issues. Some people reported Thunderbolt cable issues, I've not had any.

    I haven't tried using USB devices directly plugged into the monitor yet so can't report on whether these items wake properly after sleep as some people reported, however I think this is more likely an OSX issue as I have USB devices that don't wake from sleep properly when connected directly to the MBP via a USB adapter.

    It did take me a while to get the correct Graphics setting in Parallels due to the mode I'd been having to run it in with my previous monitor, but after changing this to the "Best for Retina Display" option, the setup is now perfect.

    If you're considering buying these then based on my experience you won't be disappointed.

    Take the Poor Reviews With a Grain of Salt

    • Written by David U from Denver

    This monitor is gorgeous! I have the newer 27MD5KB-B ("business line" model with the three year warranty, not purchased from Apple), and it works flawlessly with my 13" 2018 TB Macbook Pro (Mojave 10.14.1). Connects reliably everytime, and the display resolution, brightness, contrast and quality is as good as the 5k iMac I have at home, with slightly less reflection. Speakers aren't quite as good as those in the Apple TB display this replaced, but they're fine for conference calls and music while working. The camera is very high resolution (1080) and works perfectly too. Keyboard volume and brightness controls work seamlessly on the monitor. Granted the aesthetics of the monitor aren't quite as cool as Apple's products, but it looks better in person than in pictures. It has a nice matte black finish and the bezels don't seem as big as you might think. This monitor may have had a tough start, but it's working great for me!

    Best display I have ever used

    • Written by Philip R from Bethesda

    So many bad reviews I thought I would share. Bought this to work with my 2018 15" MBP. I am mostly running MATLAB for data analysis and software development, and Office365 for scientific papers and presentations. So far works nearly flawlessly. Occasionally a flash when the signal to the monitor seems to be momentarily interrupted - an off/on. I attribute this to software processing on the MBP and/or the Blackmagic eGPU. Absolutely the best image quality I have ever had. Expensive, yes, but I am much more productive using this ONE monitor alone than I am with 15" Retina display or 2016 iMac + Dell 4K. I actually see things in graphs and images I never saw before. For me at least worth the cost because of increased productivity.

    Outstanding Display

    • Written by John P from Hoffman Estates

    I bought this to use with a 2016 MacBook Pro, and I've had it for about year. I absolutely love it. During the course of the last year, using this on a daily basis, I've never encountered any issues with it. It powers my MacBook Pro so I literally have just a single power cable running down to the outlet and another that plugs into the MacBook Pro. That's it! It makes for a very clean setup.

    The real joy of this monitor, however, is the display. Better than anything I've ever used before. Colors are true and text is razor sharp and crisp. The more you zoom, the bigger the text gets but with zero pixelation. For someone like me who has not the best eyes anymore- I absolutely love it. I am totally pleased with my purchase of this monitor, and though the price is definitely on the high end, I believe it provides an equal amount of value.

    Love it, works very very well.

    • Written by Andy N from El Dorado

    I have been using this monitor for a year now as a daily monitor connected to my 2017 Macbook Pro 8-10 hrs/day (for video conferences 3-6 hour, email general office work. At first there were some issue with connectivity and random crashes, as expected as an early adopter of the best of the best, but as with all software-driven hardware the good folks at LG and Apple have been constantly improving both the monitor and OS software to work very well together. Using this monitor works precisely the same as my old set up (2013 MBP w Apple Cinema Display). Here are the keys to success: Open and log in to laptop before connecting the monitor, once connected you can closed the clamshell on the MBP. When stepping away, I have the screensaver set to come on after 10 min, and sleep set to 90 min, this way I can be gone for lunch and it wakes without issue. When leaving it for several hours or overnight, I put the MBP to sleep and then disconnect the monitor cable from the MBP. Following these rules, just like as I did with my previous all-apple setup, it works flawlessly and allows me to enjoy the best monitor on the market. Hope this helps.

    The best

    • Written by Sebastian S from Jacksonville

    I am not sure why all the negative reviews, I can only attribute it to user error or other hardware issues not related to the monitor. I have it hooked up to my Mac Pro. It's amazing compared to the Apple branded monitor. The picture is so unreal. I hooked it up to my MacBook Pro, no issues there neither. I am running the latest version of MacOS. If you want a the best monitor on the market, don't hesitate in buying this monitor. Don't pay no attention to the negative reviews. You have to tweak the monitor, you have to set it as your primary screen, etc..it's not a monitor issues, it's a user issue. So rest assured, this monitor is the tops of the tops.....but do yourself a favor, buy it open box somewhere and save a few hundred....great monitor. In fact, I am searching for my 2nd one currently....

    Great Display

    • Written by Peter H from Belper

    Don't be put off by the poor reviews of this monitor, although it obviously had some initial shielding issues, these seem to have been sorted out. It may also not be the greatest monitor in terms of style but actually it's not bad and you soon get used to it. The picture quality really is very good and it works a treat with a MacBook Pro via USB-C.
    My only negative is that I wish it had more thunderbolt 3 connections as my audio interface still needs to be connected the MacBook rather then the monitor. Yes it's expensive but can pick up recon ones for a lot less, I just didn't want to risk it.
    Go for it........

    Best Display For MacBook Pro 15" Users

    • Written by James K from los angeles

    Personally, I never encountered an issue with wifi, waking up, power, or brightness issues, not sure if this was a previous issue, but for me it was a non issue and I own a earlier and a later model of these monitors. The only issue I have occurred is when connecting a 3.5 audio jack speaker setup, they will pop for a few seconds upon waking up the MacBook Pro (clamshell with twelve south stand), and then turn on like normal. Needless to say, I own two of these monitors and couldn't be happier with them, one for the office and one at work, one MacBook to power them all, keeping it real simple, although I purchased this for use with the MacBook I wish this monitor could power 5k resolution with other models such as the Mac Pro (only 4k) or maybe even pc models for better off label use.

    Onto the review, the build quality is mediocre but with a metal stand, plastic bezel, nice camera/mic/stereo, it looks great and in person looks much higher quality than expected and the the tremendous amount of adjustability you get is also a plus. I didn't buy this for the style, mainly the display and the convenience of being able to power a 5k monitor, camera/mic, stereo, power, usb c hub with my MacBook Pro.

    Thank you for bringing out a solution for us MacBook Pro owners. Using this monitor, a bluetooth keyboard, and bluetooth mouse as made my life much more convenient.

    Very happy with this game changing purchase for my MacBook.

    • Written by Ryan H from Temecula

    I purchased this display on 8/29 and all I can say so far is WOW. The LG UltraFine 5K Display is a fantastic display that works exactly as I expected it to, so far. I had the Apple Thunderbolt Display for the past 5 years and loved it, and I was hesitant to replace it due to all of the negative reviews this display has received. However, I think most of that is from the early rollout and issues have since been corrected.

    After one day I was glad I replaced the Thunderbolt Display; this one has such a crisp picture that is so easy on the eyes because of the high refresh rate.

    I highly recommend this product, especially if you have a 2016/17 Macbook Pro.

    Beautiful 5K Monitor

    • Written by Sitthipong T from Denver

    I'm glad I bought this monitor for my MacBook Pro 2018, after having read all those bad reviews about the issues when it first came out to the consumer market. It's so beautiful, the image, colors, pixel density, etc. I don't have a single issue with the monitor, not even backlight bleeding, perhaps I'm lucky? It truly plug and play with my MacBook Pro, just use a USB-C Thunderbolt 3 cable. My monitor was made in Jan 2019 (901 serial no.) with the little square icon on the box and the back of the display. I believe it means the display has been properly shielded and fixed from the Wi-Fi interference issues when it first came out. It has the latest firmware version from LG, works perfectly fine with my MacBook Pro running MacOS Mojave. I bought an additional 3-year premium warranty service and support with LG just in case, since I'm planning to use it for at least 3 years.

    Picked it up from the Apple Store today. I have the latest 15" MBP, the maxed-out version with i9 and 32gb ram. Pulled it out of the box, plugged it in...my computer was sleeping and it immediately snapped on and has worked absolutely flawlessly in every way ever since. Beautiful picture and extremely simple to use for its primary function, which is what I expect from any Apple product so I'm glad this monitor from LG delivers there.

    I'm a software developer by trade and I just had a very productive 8 hour work session on this monitor. I did not experience any drop-outs, interference (I have some high-end audio gear right near the monitor and no issues so far), or light/dark problems like others mentioned (reading documentation on a light background and swiping over to my IDE with a dark background, it works as expected).

    I've gone through so many different monitors--the Apple Thunderbolt monitor, a pair of Dell 4K 24" monitors, and a BenQ 32" design monitor. I already love this one more than any of those because it's the perfect size and resolution and fits in really well as an addition to the 2018 MBP.

    I'm guessing LG worked out whatever issues the other people here were dealing with, or maybe it wasn't the monitor...

    Amazing 5K monitor...don't understand the negative reviews

    • Written by Larry M from Loudon

    I've been using a Mac for 15 years and this monitor, placed right beside a 27" Retina iMac, looks absolutely identical! Not close...IDENTICAL. Seriously, I do a lot of photo editing and regardless of what resolution you put this monitor on, its flawless. That said, you do have to do a quick calibration with the Color Sync Utility in macOS to set the whitepoint where you want it. You can set the whitepoint to match a MacBook Pro, if you're using one with the monitor, or you can simply set the whitepoint to where you'd like your whiteness to be. That's the ONLY adjustment needed on the monitor, otherwise it comes perfectly calibrated from the factory.

    I have absolutely none of the issues some reviewers here have complained about...literally everything works perfectly with this monitor. It charges my 15" MacBook Pro (2017) as it should (85W power supply) and the three USB-C ports on the back of the monitor serve a hub to keep your MBP free of cables and dongles.

    If there is one tiny thing to complain about, it's nothing at all to do with the performance of this monitor...it's how it's made. When compared with other monitors it's just fine, but a) it's not of the thin bezel design, it has a 1/2-inch bezel on the left, right and bottom and because of the camera and light sensor on top, the bezel is slightly larger. But the case is matte black so you don't even notice this. It's not a beautiful piece of sculpted aluminum, as if manufactured by Apple. But it's made to work perfectly with a Mac Pro, MacBook, or Mac Mini. Or any other Mac with a USB-C port.

    Honestly, this monitor is a class act! Yes, it's expensive...but so is that Mac you're using it with. If you have a

    A wonderful though expensive monitor

    • Written by Robert B from Beaverton

    Visually, this is an A+ monitor, a wonder to behold. It is very well integrated with current generation of MacBook Pros. I did not have any of the problems mentioned by the many unfairly negative reviews. When you plug in the monitor, be sure to use the port on the back with the powerbolt to connect to the MacBook. I DK how this does with other computers, but it works just fine with my 13" MBP...though I'm not trying to play video games. It's great having a substantially larger desktop. But it's expensive. The Dell 4K monitor that it replaced was around $500, so it's hard to justify $1200. On the other hand, Dell's 5K monitor goes for nearly $3000. I'm rating it solely on it's visual quality, not on how good a value it is.

    Works Great - no issues other people have noted

    • Written by Michael K from Houston

    I was hesitant after reading a lot of negative reviews about sleep, monitor brightness, connectivity/setup and other issues. Simply said, I have not had any problems. The monitor wakes and sleeps with my computer, brightness is always at my preset level, speakers and video are acceptable (it's a monitor, not a Bang and Olufsen home theater system).

    The picture is beautiful, the monitor size is perfect for work at home or tech/visual-heavy work, the icon and text size are precisely what they should be, the screen adjustment makes setting up an ergonomic workstation a cinch and the USB-C design means I only have 1 cable for display, sound and power for my macbook, finally free from the cluster*&#$ of cables past. Finally, the built in power converter also means no clunky junk on the floor.

    My only suggestions for improvement would be:
    1. Build feels a bit cheap for the price. The tradeoff - metal casing or a heavier build would make it heavy
    2. Minimalist on-screen controls (as in 0) can leave one feeling lost when looking to adjust screen settings like brightness and contrast (I never actually figured out where/if adjustment is possible)
