    It just works....not!

    • Written by Bernd A from Wiesloch

    I have a MBP 15" late 2016 and thought that 2 of these monitors would make a perfect setup.
    The monitor has a great resolution. This is definitely as good as I expected it to be.
    Here comes the 'but'
    Well .... it just doesn't work. Even after the latest macOS upgrade my MBP still crashes every time it tries to come back from sleep mode.
    In addition to that the external USB keyboard attached to one of the monitors is not recognized after power is cut of and turned on again.
    Solution here: unplugging the USB cable from the back of the monitor.
    Also the sound output doesn't stay on the selected monitor but always switches back to the other one.
    Overall a poor experience.
    Very sad.....

    I purchased 2 LG Ultrafine 4ks and 1 LG Ultrafine 5k. It's been a fairly problematic experience.

    The problems:
    (1) The 5k's color temperature doesn't match the MB Pro's screen -- these are supposed to be color calibrated, but the 5k is noticeably warmer
    (2) None of the LG's will turn on when I power up my laptop if they're plugged into the laptop -- Apple's answer: there's an issue if you have Filevault turned one... they're working on it (still) -- I can't give up encryption so I'm stuck with buggy hardware
    (3) The 5k throws the CPU into over drive when the screen saver turns on and the screen flickers red -- that just seems like a driver issue that they ought to be able to fix
    (4) Kernel panics -- I've had several instances when I've come back to wake up my laptop and it won't respond; eventually I get a forced reboot with Kernel panics.

    Tim - if you're going to promote a product geared towards professionals from the stage, make sure it actually works in configurations used by professionals... I use Apple throughout the day: Macbook Pro, iPad Pro, Apple Watch, iPhone 7+, Apple Tv... overall, the experience has been buggy and frustrating. I'm starting to feel like I'm hanging out with a bunch of fashion show debutants instead of working professionals... bring back the stability that made us confident to shell out thousands of dollars a year...

    Update, if possible needed.

    • Written by Stephan R from Abu Dhabi

    I don't care about design I need it functional and easy. Using just one cable is the best best solution for me. The displays resolution is amazing, the size brightness and clearness is stunning. But the functional issues are with a lot of problems. Example: The display has 3 USB-C ports on it's back. My configuration is one is using 4-Port USB 3 Anker Hub and one is using Belkin Ethernet adapter. If I reconnect the Macbook 15" to the display, both adapter don't wake up. as long as you reconnect each dongle on display's back again. That's not comfortable. Even the sound is just average but better than nothing

    Potentially near perfection but flawed.

    • Written by Douglas W from Glasgow

    When this monitor works, with my 2016 15" MBP, it is truly stunning in 5K image quality. Editing in Lightroom CC is a real pleasure. I like the minimalist unobtrusive black plastic design. The heavy base makes it stable and the height adjustment is superb. I use it to extend the display of the MBP and it adjusts so that the screen is just above the open MBP screen. The sound is reasonable given the slim design. On the downside, I have suffered the flickering if too close to my AirPort Extreme so I have moved that. I get occasional blackouts and freezes while using Lightroom CC. I have had to reboot both my own and a friend's similar MBP when connected to this monitor. I have problems with sleep and power off when connected to the monitor. After power off the monitor might not be recognised so I need to unplug and replug it. After power off or sleep my two Porsche design desktop 5TB drives which are plugged into the monitors USB-C ports might not be recognised and if awakening from sleep I get an improper disconnection message. When the monitor is plugged in I sometimes get a problem with my login password not being recognised and I have to reset it using my Apple ID password. Apart from the flickering I am not sure whether the problems are due to the monitor or the MBP software or both. A real pity that these minor glitches have spoiled it.

    Nice! Most of the Time. Alphanumeric letters sometimes look funny!.

    • Written by Thomas J A from MIDDLETON

    A Mac Product Thunderbolt Display IT'S NOT! I paired this to a 2016 MacBook Pro with the nice but gimmicky Touch Bar - nice but wouldn't do it again. I need a large screen as the years affect vision. The LG 5K Ultrafine Display provides a remarkable display, but it is not consistent! I've had the display for 2 months. Fortunately my 2012 MacBook Pro 15 inch is paired to aMac Thunderbolt Display in another room. Yes, the LG display is very nice, but sometimes the image does not display. The most bothersome feature is that alphanumeric characters sometimes aren't displayed correctly. I must reboot from time to time. I've said before: THIS IS NOT AN APPLE PRODUCT and if future software or firmware updates do not fix the reliability issues, Apple has lost a customer. A 3 decade Apple fan, I planned to be a "Customer for Life." I'm giving you a chance, Apple. Don't promote a sometimes unreliable product. That's why I left PC's.

    Great picture, dodgy firmware

    • Written by Christopher N from Thornton Cleveleys

    It's very disappointing that the monitor doesn't provide any standard USB sockets or other connections. I've already got 4 USB-C/Thunderbolt 3 sockets on the MBP, one is used to connect to the monitor and now I have 6 spare connections - (and loads of dongles).

    As most people report, the sound settings on the monitor are very dodgy. Anything above 1 "pip" of volume is loud, above 2 pips and it's distorting a little because it's so loud. Inclusion of a webcam and microphone is very handy but the large base protrudes out the front a lot which is a little annoying on a small desk (can't push the keyboard forwards enough).

    Also, not often, but once or twice, the monitor has suddenly gone black - after a minute or two it comes back but has clearly disconnected from the MBP during the period. I was in the middle of a skype call once and the camera, mic, etc, disconnected but the call continued.

    Great, except for one major flaw: light leaking

    • Written by William R from Copenhagen

    This is quite a good display. The extraordinary panel with 10-bit colors per channel, P3 colorspace is is gorgeous, and actually at a very good price for what you get. However, the major flaw has to do with light leaking around the edges of the display, giving the panel an uneven look. This is mostly visible with even black og near-black images. The build quality is definitely way below Apple quality. If you squeeze the bezels of the display you can see the panel light distorting. I wouldn't really mind this if it weren't for the light leaking.

    Good but has issues

    • Written by Robin H from Altrincham

    The display looks much better once you have it than the photos and the display quality/resolution is wonderful.

    I am having issues with it though when connected to a new RMBP 15 inch with Touch Bar - it sometimes does not connect to the laptop when plugged in. Also sometimes the display turns off to black for a couple of seconds then on again three seconds later.. it does this continuously until you plug it in and out of the laptop a few times. If it continues to do so I will probably have to return it though unfortunately.

    Bring back Apple Cinema Displays!

    Apple brand, high quality (and high margin) displays. Just make two needed changes - a smaller border bezel and the SAME HEIGHT as an iMac for a consistent side-by-side experience.

    Same "flicker" problem...possible solution?

    • Written by Trent S from Santa Monica

    I've been dealing with the same screen "flicker" issue that many others have reported. Right out of the box my UltraFine display was consistently shutting off and turning back on every 10 seconds or so...beyond usable. Thanks to the power of internet think, I narrowed it down to the WAP proximity issue. To clarify, I connect my UltraFine 5K to my iMAC 5K via Apple's Thunderbolt 3 (USB-C) to Thunderbolt 2 dongle...no issues there. Everything sits on a shelf with my Airport Extreme, cable modem and Sonos BOOST all directly below.

    After days of non-stop screen flicker, I tried messing with the Wi-Fi channels on my Airport. Jogging through various Wi-Fi channels did actually seem to affect the amount of flicker. In my case, the issue ceased completely after I separated my 2.4 GHz and 5 GHz networks and set them both to Automatic. (The Wi-Fi channels were manually selected before.) I'm now one week in with regular use and have experienced ZERO screen flicker/connectivity issues.

    Hope this helps - The 5K display is great otherwise.

    Beautiful screen that matches the MBP screen perfectly, but, screen flicker

    • Written by Larry P from Chilliwack

    The screen periodically flickers and cuts power to the MBP shutting down attached external drives and sometimes requires a reboot. Seems like it might be that the Thunderbolt 3 cable is defective, but am unable to find a replacement. The Apple online cable does not meet the operating specs regarding providing power to charge the MBP. However, when screen is stable it works well. The flicker and power drops is very frustrating and disappointing. So close yet so far from being a perfect work station. :(

    Issues using the Belkin USB-C to Gigabit Ethernet Adapter

    • Written by Carlos H from San Francisco

    Using the Belkin USB-C to Gigabit Ethernet Adapter doesn't yield the maximum speed possible. If I connect this adapter to my new MacBook Pro, I get between 850Mbps to 950Mbps. Connecting the adapter on this 5K LG monitor the maximum speed I get is 300Mbps. Another issue that I have is that the monitor suffers from wireless interference, specifically wireless routers.

    The screen itself is gorgeous, colors and resolution just pop. Not happy about the design though.

    Beautiful Picture, When It Works...

    • Written by Ryan M from New York

    I have to main issues. 1) Sometimes my MacBook (late 2016 15") turns psychedelic. Like, tons of random very bright colors and extremely difficult to see content on the screen. 2) Often, when I plug the monitor into the laptop, the monitor starts out on the dimmest setting, no matter what the setting was the last time the screen was plugged in. This seems to happen inconsistently, but typically multiple times per day.

    Not bad, but not impressive either

    • Written by Imran M from MISSISSAUGA

    The fact that this monitor was launched alongside the 2016 MacBook Pro during the keynote, I though it was Apple's seal of approval. My experience has been anything but. Having a 5k display is truly awesome. But the monitor does not impress. For starters, I've had nothing but problems with my machine crashing regularly when connected to the monitor. Apple suport's solution - work with the computer with the monitor unplugged. Huh? I eventually had my main logic board replaced - but still no resolution. I've just given up and live with the crashes.

    Then there are ghosting issues. Sometimes after I minimize a window, I can still see a ghost image of the previous window on my desktop. Not cool.

    Lastly, though it puts out power to charge your MBP, the charge is not the same voltage as the power adapter. Also not impressive.

    Overall, the 5k display will blow you away if you compare against other monitors that are not 5k, but it does leave a lot to be desired. I would not recommend buying this monitor.

    Quirky wake up, sound too loud

    • Written by Kevin M from MORRO BAY

    First off, the display quality itself is fantastic. That's the good news. On the downside as others have mentioned, it is a bit quirky when waking up. Probably one out of five times I have to reboot the computer or at least lift the lid of the MacBook Pro instead of simply touching the touchpad. Also some issues with the camera not being recognized from time to time. Never had these issues with the Thunderbolt monitor the LG replaced.

    But the most frustrating problem is with sound. It's way too loud, even with just one bar, so I can't stream background music through it without annoying people in the office next door - again, like I used to with the Thunderbolt. I've had to resort to using wireless headphones, which have other disadvantages in terms of using the phone, visitors, etc. I've tried adjusting the sound directly in settings, but no luck.

    • Written by Chris K from Laguna Niguel

    You would think the top of the line display in the Apple Store would work with the "top of the line" desktop in the Apple Store but you would be wrong.

    Nowhere is this incompatibility warned about. When I went to the retail store I even told them I was planning on purchasing both together and no one said anything.

    The upshot is that the Mac Pro is thunderbolt 2 and this display uses thunderbolt 3. The result of using Apple's TB2 -> TB3 adapter, for whatever dumb reason, is that the display must run in 4K instead of 5K. Well, 4K is still pretty good, you might say… but you'd be wrong because a display not run at its native resolution is not as sharp, which kills the whole reason of having a nice Retina quality display with the awesome gamut touted.

    You'd also be wrong because of the next two incompatibilities:

    (1) The display has only ONE thunderbolt port. That's the one you use to connect it to your computer. The rest of the ports are USB-C (not Thunderbolt). So you're not going to be able to connect thunderbolt peripherals to your monitor even if you purchase Apple's Adapter. Nowhere is this incompatibility stated either. I had to spend an hour chatting with Apple support staff before this came up.

    (2) On the Mac Pro, this display will not turn on until the OS is up and running. This means you are not able to access the boot screen, which means you're not going to be able to do things like choose startup disks, Boot Camp, recovery mode, or single user mode, etc.

    Add up all of these factors and it makes this display, which would be a great deal when compared to Dell's 5K display, an overpriced dud. You're better off locating a dedicated 4K display if you want retina-level graphics. Which, I've found, is surprisingly hard to do (LG has a 27" 99% gamut UHD IPS display available but it's selling out everywhere). So, failing that there are other decent sub 4K type displays that are still pretty good in the resolution department.

    Anyway, extremely disappointed they didn't even try to make this work with Mac Pro using two cables, which is supported in theory even if there are no actual displays on the market available to do that with.

    Other than that, it's a VERY NICE DISPLAY (if you have the latest MacBook Pro, is basically the only usable option)

    Great display, but no support offered

    • Written by Nils W from Konstanz

    I'm using this display with a 15-inch Macbook Pro. The quality is not what you would expect from Apple, but it works fine and the picture is great.

    I contacted Apple Support today about the volume adjustment issues that are mentioned in many of the reviews: using the keyboard volume controls, it is not possible to fine-tune the volume to an acceptable level.

    Apple first responded that they were not responsible for this product, and that I should contact LG. I did that, and got the same response from them (contact Apple). So here we are, with an expensive display and no support, neither from the manufacturer nor from the seller. This must be a joke.

    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.

    LG 5K & WIN10 under Bootcamp

    • Written by Peter T from PRAHRAN

    I have a late 2016 MBP 15" running in Bootcamp under WIN10.

    I have no idea how the AUDIO is supposed to be configured to use the LG Display as the OUTPUT DEVICE - any advice or assistance would be appreciated. The AMD drivers

    Resolution, when running Bootcamp and WIN10, is sadly limited to 4096 x 2304. Had I known this is would not have committed to this purchase.

    It continues to disappoint [as a decades-long business user of Apple products] how Apple continually 'dis-owns' issues when Bootcamp is mentioned - even though Bootcamp is developed as an Apple product. It is apparent that little training [at least insofar as the tech service I've experienced] is focused on the Bootcamp environment. I wish there were product specialists in this area.

    Generally, I feel the Display has potential. We are multi-media content creators and designers.

    The display's Gamma appears nowhere near as high as the Apple Retina displays - either MBP or iMac, so images and, in particular, text is not apparently as sharp - despite the fact that the LG Display has a glossy screen surface. I suspect that there is actually a dual layer surface happening on this display with the gloss surface acting more as a 'protective device'.

    Frustrating issues like the general "set-up and configuration" aside [which is very poorly documented, and mostly non-existent for Bootcamp users], I have hopes that Apple will put some effort into making good my ~$1,500 purchase right and up to Apple's expected high standard.

    Any assistance with the AUDIO would be appreciated.
