    Erratic 4K dual monitor perf.. Sloppy for Apple.

    Sloppy execution for 2 monitor display. Only one of monitor wakes up from sleep. The monitors don't charge the Macbook pro 15 and the battery drains till the system shuts down. Lost unsaved work. The primary plug in cable is only USB c. Did not recognize belkin thunderbolt3/usbc sold by apple.

    What happened? After 3 years of waiting... We are still waiting. Needs more work either from LG or from apple

    Not just LG UltraFine

    Hi,
    I do have exactly the same problems of black screen, crash, not waking up, "plug-unplug-crossing your finger" game with my Lenovo Thinkvision X1 27" 4k USB-C monitor and MPB late 2016. So, I doubt that all of our problems are due to the poor design/quality/whatever of LG or Lenovo. This whole experience rather underlines the steady decline of quality assurances at Apple that at least I have experienced in the past years. I'm seriously contemplating leaving Apple behind (what a shame!!) because of reliability and quality issues and the lack of sufficient customer care, including warning, information, etc. Although I put only 1-star at the rating but I'm sure that this 1-star should really go to Apple and not LG.

    Looks great, when its running properly

    I will echo many of the concerns here that many others have. The big one is the random black screen and freeze waking up from sleep which is a problem losing work the use of open applications etc. The next is not having the ability to daisy chain to another monitor if needed. I was told to troubleshoot myself and unplug the USB-C chord before I put the new 13" mbpro to sleep. Really? I can't see myself unplugging the chord every time I put the mb to sleep. Also I find myself constantly having to adjust the settings for brightness as they seem to reset themselves. Overall its great to have the plug and play feature of just one chord, but not having any support and being pointed towards LGs site for firmware and software updates that don't address the big key issues here is a problem, especially for a 22" monitor that is over $600

    Cheap and buggy. Not apple quality.

    Buggy garbage. I expect better from Apple and was happier with my old thunderbolt display. Using two 4k displays with new 13in Macbook and often one or both displays gets corrupted or freezes after waking up the computer from sleep. Unplug...plug. Unplug...plug. Cross fingers. Plug...unplug.

    I expect better from my apple products.

    Love 4K - hate 5K

    I have had the LG Ultrafine 4K since receiving my MacBook Pro 15" (late 2016, touchbar) and it has worked beautifully. Decided to replace my Apple Thunderbolt display with the LG Ultrafine 5K for my 2 monitor setup. The 5K has been a disaster. Black screen, screen flashes, eventually leading to a locked up computer. My Ultrafine 4K on the other hand works perfectly. I did have the Apple Thunderbolt Cinema display set up, until I moved it to another location. Two monitors worked great - until I added the Ultrafine 5K and Ultrafine 4K together.

    So now I'm back to a single 4K while I work through or return the 5K situation. Interesting to me, that people here are having a problem with the 4K similar to my 5K problems. The 5K uses a Thunderbolt 3 cable, the 4K a USB-C. One monitor works, another doesn't. Hesitant to add a 2nd monitor as it seems many with 2 4K's are having problems. Don't yet know what I'll do.

    bad experience

    This display is ONLY compatible with the most recent macbooks that have a built in USB c port. I even bought a USB c to HDMI cable to try to connect it but since the display only turns on by plugging in the USB c cord, the display is completely useless. Apple should do a better job of specifying that it only works with USB c enabled macbooks, as most people do not own these yet. I'm sure it would be great but it doesn't work with most apple computers.

    The 5K Display....

    I have the 5K with a MBP 15"...Apple should be ashamed. The display wakes erratically, sound setting do not hold and just glitchy behavior. I bought this from Apple and while I know this is not an Apple product, Apple is promoting this as a strong display. I hope that software updates will occur...the display control panel doesn't work on Sierra fully and there is just so much wrong. I'm sorry I upgraded to a new MBP and this monitor. I've been a lifelong Apple user and fan, but some of this lately is causing me to wonder. That's big for me.

    Incredible screen and color accuracy - but has one major problem

    I bought two of these LG Ultrafine 4k displays and they are hands down the best display I have ever owned. The picture quality and brightness is incredible!

    The only problem so far (owned them for 2 weeks) is that it doesn't wake up after my 2016 Macbook Pro 15 goes to sleep. You have to unplug the USB C connector and plug it back in.

    Great when it works, incredibly frustrating most of the rest of the time

    I'll keep my review short. This monitor pretty good when it works with my 2016 MBP13 with touchbar. However, it is constantly causing crashes usually when waking from sleep. Very frustrating experience.

    The Perfect Companion to my new 2016 MacBook Pro!

    Having used Apple’s Thunderbolt display in the past, I was really excited for the introduction of an “Apple-sanctioned” display designed to work seamlessly with my new MacBook Pro. I also wanted to take advantage of the sale price since the UltraFine display is part of Apple’s current USB-C accessory discount program.

    Unboxing the display was simple. Open the box, remove a styrofoam block that keeps the display secure during shipping, lift the unit out of the box, and remove the soft wrapping that protects the screen and base. Then on to a small accessory box that contains the power and USB-C cables. It also has a sleeve containing warranty and instructional docs. A VESA mount is also included in the accessory box.

    Setup consisted of connecting the power cable between the display and outlet, and the USB-C cable between display and MacBook Pro. My mac immediately recognized the display.

    The screen is absolutely gorgeous. Bright. Brilliant. It looks identical to the Retina screens we know and love. And for practically half of the price of the recently-discontinued Thunderbolt display.

    I like the simple black design aesthetic. Very clean looking - no distracting LEDs or rows of buttons to mess with. I personally like the 21.5” size - not too big, not too small, either. Perfect for my needs. If you’re a graphics professional, you will probably want to check out the 27” 5K version.

    To be fair I will admit that the cable management could have been handled better. Perhaps in a future version they’ll add some type of channel or tie to hide the power and USB-C cables behind the stand. As other reviewers noted, it does not have a FaceTime camera. This would have been nice, but certainly not a deal breaker for me.

    LG UltraFine 5K locking up too

    I purchased the LG UltraFine 5K 27" monitor from Apple as soon as it was available. Received it today and I am having the same issues with it suddenly going dark (black). You can click the mouse a few times and it will intermittently come back on, but eventually just stays black. Then you have to disconnect and reboot your MacBookPro to get its screen to work. Spent time on the phone with Apple Support today, but all I got was a request to gather more data and they will get back to me.

    Too many problems w/ MacBook

    Bought this for my wife to connect to her late 2016 retina MacBook. The monitor itself looks beautiful and strikes a good balance of size and pixel density. Also I love how the monitor charges the MacBook with a single cable.

    Problem is, as many other users have noted, I have an issue where the screen flashes black (goes off and on), which happens once every 3 minutes or so, which is enough to be super annoying. No amount of support or troubleshooting has led to any solutions here. It's very frustrating since both the macbook and monitor are brand new and are advertised to work together.

    Another thing is that, contrary to a couple of reviews here, with the latest OS X there doesn't seem to be an option to run the monitor in 4k at 60 Hz (have to use 30 Hz which looks very laggy).

    Worst Apple endorsed product since the Motorola Rokr

    How do you get USB 3.0 speeds at all with a Macbook and this display?

    It is not possible to use the display combined with the USB-C Digital AV Multiport Adapter to get a USB A 3.0 connection. The display is just dark.

    You cant connect your Macbook to the display with any other USB-C cable than the black one provided in the box?? Apple ones leave the display black.

    The USB C connectors on the back of the display seems to have such very low power output that they barely can drive my Happy Hacking Keyboard, I get warnings.

    There is no FaceTime camera on the 4K one, I expected that.

    Speakers and screen are ok, but the display is a compatibility nightmare.

    Stability Issues with MacBook Pro 15" w/Touch Bar

    The display looks great, but I had SOO many issues with the display. It caused my MacBook Pro to crash repeatedly, especially when waking from sleep. Even kernel panics. The 10.12.2 update did help some, but my apps would still crash several times a day. I believe it even caused a corruption issue when copying data from my old MacBook Pro via target disk mode (over Thunderbolt using Thunderbolt 2 to 3 adapter). It corrupted both volumes on the old machine when it went to sleep overnight and I lost ALL my data. Weeks later, I'm still recovering from various backups. It has caused many headaches. Called Apple Support and they couldn't really help but suggested I try the MacBook Pro without the monitor, and sure enough, all my crashes went away.

    Returned it and got the LG UltraFine 5k. Works like a charm! Day 2, zero crashes or sleep issues! Presumably because it uses Thunderbolt and not USB-C. Seems like Apple has some bugs to work out (or maybe it was an issue with the display itself or the cable). If you have a MacBook Pro, get the 5k instead. Also keep in mind that the 4k can't charge your 15" Pro (only provides 60 watts vs 85) and has slow USB 2 ports, plus no camera or mic.

    If you are used to Apple displays, don't expect the industrial design to be nearly as nice. Both monitors wobble when I type and just don't look as good as Apple's Thunderbolt display did. But the panel itself is INCREDIBLE.

    Hope I helped.

    Does Not Wake From Sleep; Causes Macbook Pro 2016 to Crash

    I purchased a 2016 13" Macbook Pro with TouchBar and (2) LG Ultrafine 4k displays in November. Upon installation I was disappointed to learn that the monitors could NOT be daisy chained. Running (2) displays requires (2) connections (USB-C) to the MBP.

    Unfortunately having to utilize (2) connection was only the beginning of my disappointment. The LG Ultrafine displays and the Macbook Pro are NOT compatible. At least one of the displays fails to wake every time that the MBP goes to sleep. At times both displays fail to wake and the MBP becomes unresponsive and requires a restart. Further, several times a day the displays cause a sleep wake failure which crashes the MBP.

    I have been in contact with senior Apple support staff every couple of days for an entire month. Apple engineering even went as far as capturing my MBP and sending me a new MBP. I received the new MBP and have been experiencing the exact same issues for the last two weeks.

    I am a long time, loyal apple customer but this experience has led me to question Apple's Product Development and commitment to quality. It is inexcusable to market these devices as being specifically designed to work together seamlessly and then offer no support. After more than (6) weeks of frustration, lost data, and unproductive work days, it looks as though I will have to return all of the Apple hardware.

    Great resolution, one-plug use, random power on/off while working

    Resolution and simplicity of use are as other reviewers say. Mounted quite easily on an Ergotron wall-mount.

    Here's the rub: When I'm working, the monitor randomly powers off (black) for 2-3 seconds, then powers back on. Happens 10+ times per hour. Goes black just enough to interrupt thought processes.

    Worked with Apple support in mid-December. Reset PRAM & SMC. This has not fixed the issue. Support said they have no experience with the monitor. Maybe it's a firmware issue or OS issue. (MacBook Early 2016, Sierra 10.12.1)

    Fantastic Companion for 15" MacBook Pro with Touch Bar

    Works superbly with 15" MacBook Pro with Touch Bar. Color and resolution are fantastic. The stand is nice and sturdy, and lets you place the monitor high enough so that you can use the laptop below it without obstructing the screen. The speakers are also quite serviceable.

    It also provides plenty of power for the 15" model. Despite multiple reviews to the contrary here, the charging works just fine when you have devices plugged into the USB-C ports on the monitor. Specifically, I have charged an iPhone and another smartphone, plus run an external USB hard drive, while also charging the laptop via USB-C ... no issues.

    My only real wish is that the USB-C ports were USB 3.1 rather than USB 2.0, but that's just a necessary limitation since it does not connect with Thunderbolt 3.

    Overall an extremely good monitor, and the convenience of having all your connections via one USB-C cable is very nice.

    At a loss of words for the poor experience I'm having so far with these

    We ordered 3 of these at work, 2 of them being for my use. Today I finally got my new 15" MBP to hook up to them and check them out. Initially they looked pretty good, although I had the UI designs I was working on one of them, and it didn't take very long before I was feeling like everything was quite a bit greener than on my laptop or 5k iMac at home. Later in the day it really started to bug me, and I realized the colors on the 2nd display seemed fine, so I put up the same screen on both displays, and sure enough one has a much greener cast. I tried switching cables, checking profiles, even flipping monitors to see if its just an angle thing, etc. Nothing fixed it, the one monitor clearly just has a much greener cast. So I decided to borrow my co-workers and hook his up and see how it looked. Strangely enough it didn't match EITHER of the 2 I had, and was somewhere in between as far as the green cast. Now with all 3 monitors sitting on my desk , we noticed an even weirder thing. All 3 were physically different heights. At the max height on all monitors there was about a 4-5mm difference in heights from the shortest to tallest all lined up. All I can say is wow! Really feel like Apple has robbed me for the first time in the many years as a loyal customer. I'd actually like my old 2015 MBP and old monitor back. Better and more consistent experience, even if the "specs" weren't as high.

    Excellent display

    I chose this display over the LG 5k display based on price and availability for my new Macbook Pro 13. It's an excellent display; bright, even illumination, sharp colours and loud but not high quality speakers. The LG utility available on the U.S. LG site is pretty useless unless you want to divide your screen up into multiple screens. I like the way it's easy to adjust vertically. Would have been nice for it to turn easier, but no big deal. Comes with a reasonably long ~3' cable for the Macbook Pro so that's good. I also like that it charges the computer too. It's colour and saturation is a little different than the MacBook Pro screen. I was planning on adjusting the computer to match but after a couple of weeks, I have adjusted my expectations instead. Ennui wins out.

    I did not know that there is a big difference between Thunderbolt 3 and USB 3.1. They both use the same USB-C connector but USB will run over Thunderbolt but Thunderbolt won't run over USB. This monitor is USB, not Thunderbolt so I can't plug my Thunderbolt drive into it. The LG 5k monitor is Thunderbolt so I could have plugged my drive into it. If you want to plug a Thunderbolt drive into your monitor, buy the 5k version. You can plug a USB drive into either monitor.

    Great monitor highly RECOMMENDED

    I would recommend the 4k monitor to anyone who's looking for a stunning bigger display for their 2016 MBP. I have been using it with my 2016 MBP and I'm very impressed with it. I would recommend it all day.
