    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!

    Get a Thunderbolt Display instead!

    • Written by Chris D

    This is the worst monitor I ever owned. Nothing but problems and issues...I ended up just buying a Thunderbolt Display on eBay for $650 and its pure Apple quality. The LG just kept turning off and on all the time on its own and the color on it wasnt very good. Recommend to get a Thunderbolt Display instead, works great no issues.

    Ghosting / image retention

    • Written by Lisa L from Lafayette

    Initially, I really loved this monitor. But, after 1.5 years the ghosting is so bad, it's almost unusable. Expected more given the cost.

    i don’t think you should buy this monitor…

    • Written by Todd L from Farmington Hills

    i never write reviews, and i LOVE everything apple (i even love apple products with some flaws)… but i bought this monitor and:

    - it was tilted to one side, and could not be straightened, so it was replaced, then…
    - it had a very strong green cast to it, which could not be fixed either by calibration or by a factory reset. the apple business team members who helped me (they’re great!) even checked this same monitor which was set up in the apple store and confirmed the strong green cast.

    maybe you don’t care if there’s a green cast (assuming you don't first get one with a permanently-tilted screen) but i do desktop publishing and design and i need a monitor that can represent at least fairly accurate colors… so i bought another brand.

    I have never taken the time to review a product on the Apple site before, but am so disgusted by what's transpired, I felt compelled to share my experience with others.... Beyond disappointed with my purchase. This hunk of overpriced junk does not work as described. First, you have to purchase a different cable.... the one that comes in the box does not work properly, and is incapable of transmitting data at the required speeds (20 vs 40gb/s)... this was something that was recommended to me by an Apple Genius when I complained that the screen wasn't working as promised (she also said that it seems to sometimes work better if you use the ports on the right side of the computer, but that doesn't seem to make a difference for me). Second, it works sporadically... at best. Sometimes, you plug in your computer and it works just fine (maybe 2 out of 5 times). 1 out of 5 times, it doesn't work on the first go, and its a game of plugging and unplugging until the monitor decides in wants to work. Probably 2 out of 5 times, there is nothing at all. No image, no connection, no nothing. Restarting the computer *occasionally* makes a difference, but usually not. So 2 out of 5 days/week (I take my laptop to and from work every day) I am wholly unable to use this monitor.... completely unacceptable for a $1300 screen.

    Works great

    • Written by Peter M from MOntreal

    Not sure why all the bad reviews. Unboxed, plugged into my MacBook Pro, works just fine. Insanely crisp text, love this being a graphic designer. There are clearly more colors visible. 4K video looks insanely good. Running this monitor with another 4K monitor. 2 wires, MacBook in clamshelll mode, wireless keyboard and mouse. A thing of beauty. Thick top bezel a bit different looking but I like it. The base is nice and heavy. Love that I can adjust the height. No more starting up at my iMac which puts extra strain on the eyes.

    It took time

    • Written by Mark R from Derry

    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 . .

    Wobbly, single input

    • Written by David B from Concord

    No one can responsibly buy one of these without seeing it in a store. It wobbles if you breathe on it. I've seen better constructed stands on $180 monitors. This was not a one-off abused floor sample. Many reviews say the same thing.

    This monitor only has a single input. That was also a deal-breaker for me; I maintain other machines.

    I'm buying the just-released LG 32UL950-W 4K monitor at this same price. My one reasonable fear, having seen that LG can sometimes build junk, is that this will also have a wobbly stand. Some LG stands are fine; I'm playing Russian Roulette.

    Not compatible with (almost) anything

    • Written by Matheus V from Corvallis

    It uses a non-standard Thunderbolt 3 port that carries two DisplayPort signals. This means it's not compatible with anything but a recent mac, and only when connecting directly to it. There are no adapters out there to use this with eGPUs, for example.

    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!

    Don't buy it

    • Written by Paulo M from El Cerrito

    Six weeks ago, I bought the top of the line 13in-MacBook Pro, a Blackmagic eGPU, and the LG UltraFine 5K Display. Two days ago, the monitor went blank, so I contacted customer service. The call lasted over one hour, and we tried all possible combinations to fix the problem but eventually we gave up. After that I did a careful internet search and I was surprised by the large number of people having similar problems. I hope that I can fix the problem soon by going to the Apple store but I suggest that you avoid this pain.

    Took Mine Mac Mini to Another Level

    • Written by Domingo M from South Elgin

    Own a Late 2014 Mac mini using a Asus 2540x1440 display. Hated the picture quality and sound. Forcing to invest on a pair of external speakers, taking desk space.

    During the spring, while visiting the Santa Barbara Apple Store, noticed a LG UltraFine 5K Display being hooked up to a Mac mini and was very surprise. Asked if the Mac mini will be able to drive the LG. The answer was, "We'll see." Man, did it drive it. Even the Apple tech was surprised at the picture quality and sound coming out of this set-up. Right there and then, my thoughts was, "I want one!"

    Well, it took a few months, but I finally have it and it meets all my needs and expectations. Outstanding display.

    The picture and sounds are both outstanding. The speed of moving data onto my external hard devices are just unbelievable. That's using the Thunderbolt 2 that the Mac mini provides. Can't wait for the new 2018 Mac mini with Thunderbolt 3 that HOPEFULLY will be coming out next week!

    Honestly, if the new 2018 Mac mini is NOT a giant leap, I may just keep my $$$ and stay with this set-up because how satisfied I am.

    Bought it in August of 2017. 14 months later it starts sprouting vertical always on lines. comes with a 12 months warranty so the solution is nothing but replace.

    Never had a monitor that went out so quickly or came with such little support. Never again

    DEFECTIVE PRODUCT w/no help from LG to fix it for good

    • Written by Susan F from Thousand Oaks

    I have had nearly all the problems everyone has reported from long time to connect to my MacBook Pro and the screen going black, to the monitor working 50% of the time And, during the time it is working, I hold my breath that the amount of time it flickers is less than the time I need to jam on work. The unit never worked without issue since the get go, and finally 2 days after the year 1-year warranty expired, the combination of a bad cable and a damaged C plug forced me to send it in to LG service. It took several weeks to get back. Fortunately, I could afford to buy another 5K monitor while waiting for the other one to come back. LG replaced the port/plug, but then the replacement cable they sent me went from working to working intermittently to dead over a period of 9 months. I am probably worse off now, as the stiffness and weight of the cable has once again damaged the C port on the monitor; and possibly on my MacBook Pro. Tomorrow, I plan to buy yet another monitor replacement and have an appointment with the Genius Bar to determine whether or not there's port damage on my MacBook Pro. I would not recommend this product, but realize that it is better for my eyes given my heavy use and project demands.

    Not conpatible with Mac Pro!

    • Written by David B from Fairfax

    The old and much nicer Cinema Display works better with Pro systems and look much better doing it. This display can't even run at 4K yet alone 3K resolution with Apples best computer. I wish Apple would update the specs to mention this display does not work correctly with Apple desktop computers.

    UPDATE! Does not work with 2018 Mac Mini either

    Interferes with Internet Connection

    • Written by Rod W from Teignmouth

    I would love to say I love my LG monitor - the picture quality is amazing!

    However, mine appears to have a major flaw and I'm not sure if others are experiencing the same thing. Since installing my monitor next to my MacBook Pro I've been having increasing internet connection problems with my internet freezing. I've been blaming BT and my ISP. I upgraded my router and even tried changing channels on my router and multiple other 'fixes'. Nothing worked and the problems grew progressively worse until it's reached a point where I couldn't work! But here's the weird thing - I realised that the connection problems were isolated to my home office. So I started investigating further. And here's the really weird thing - if I turn off the LG monitor, my internet connection problems are instantly resolved. Nothing else impacts performance - but the second I turn my monitor on, internet crashes. Online support were of no help and just said I'd need to take my MacBook Pro and screen a Genius Bar. It'll be interesting to see what happens...

    Beautiful, but...

    • Written by Alan H from Auckland

    The display is gorgeous and the functionality is perfect. The fact that a single cable powers your MacBook as well as handling display data is great. You can control brightness for both the LG and the MacBook from your keyboard.

    However. The plastic casing that some complained about has proven to be a problem for me. The plastic started to crack and crumble on the bottom right corner after 6 months, and the other corner joined the fray a month or so later. At this eye-watering price level we should expect better hardware.

    Kudos to Apple though, I called them this morning and they agreed to a refund with zero hassle.

    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.
