    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.

    Nice monitor, but slows on screen recording even w/latest MacBook Pro

    • Written by John G from WABAN

    I like the 27" monitor, I have poor vision. It's beautiful, but I also need to record screencasts for students. Have tried Quicktime and Screenflow, both have jumpiness, like cursor hops from location to location instead of smooth transition. No problem when recording on just the MacBook Pro retinal display. Activity Monitor doesn't go above 30% total usage. Display settings don't help - prefer Scaled, Larger Text (for vision) and a big cursor, but any setting gives cursor jumpiness. I'll be returning this simply because I need smooth screen recording.

    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.

    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)

  • 3.0 out of 5 stars


    • Written by J.P. P from Torrance

    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...

    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.

    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.

    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.

    It's alright and the audio levels are annoying

    • Written by Jason M from Denver

    It's a monitor. It works, but the audio controls are awful. The step between the first bar and the 2nd bar when changing audio levels is huge, so don't expect to listen to music quietly at night. The docking experience isn't great. It's a disappointment for the money. Much like the MacBook Pro with Touch Bar, buy it if you need it, but don't expect to be delighted.

    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.

    Great wen works... there are issues...

    • Written by Phillip I from DUBLIN

    I bought 2 of these to go with a new 2016 15" MBP. When I first plugged in 1 worked and 1 didn't. Did some research and found that if it is near a WAP it will go black. I have moved my WAP and it started working, but it shouldn't do this. Since then I have had a number of times where all 3 displays start flickering and I have to restart my computer. I love having 2 5k displays, but there are several kinks that need to be worked out with these. I'm still deciding if I'm going to keep these monitors.

    Wonderful screen, but lots of issues

    • Written by David S from Bloomington

    First, the screen is amazing. It is by far the most beautiful, bright, crisp, colorful screen I've used. This is the reason I kept the display to go with my MacBook Pro 15 with touch bar.

    However, this is clearly not an Apple device, because there are a host of problems with it:
    1. My computer regularly becomes non-responsive or restarts when I connect or disconnect the monitor, especially in clamshell mode. (I'm hoping that Apple can fix this in software.)
    2. If the cord on the back of the monitor is touched at all, the image flickers off and on again.
    3. USB devices connected to the back of the monitor sometimes don't work, and they need to be unplugged and plugged back in again (which causes issue #2). I'm also hoping Apple can fix this in software, but it might be a monitor issue that LG would need to address.

    So I'm going to buy a new cord that I hope will fix the flickering in #2, and hope that Apple or LG can fix the other issues. This is definitely NOT an Apple product or experience, but at least it doesn't have an Apple-like price tag. Overall, though, it feels like a downgrade in quality from my previous Apple display in every way expect the screen. I would have gladly paid to get the Apple experience, but this is the best option for now.

    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.

    Beautiful picture - unreliable behavior

    • Written by Douglas F from Rehoboth Beach

    The screen image is amazing! But, we returned it because it caused a 2016 MacBook Pro to crash when it woke from sleep while connected. The only fix (suggested by Apple support) was to keep the MacBook Pro plugged into an external power supply - this did prevent the crashing. Since neither Apple nor LG could offer a fix (except the possibility of a future software update for the monitor) we returned it -- for this money, the inability to use it via a single cable as advertised makes it too expensive for a compromise.

    MBP 13" (late-2016) crashes when plugged/unplugged from monitor

    • Written by Geoffrey K from New York

    As others have noted, my MBP crashes and is forced to reboot if I unplug it from the monitor when it is in sleep mode.
    If the MBP is open and working, I can unplug/plug it without issues.
    This is clearly a major nuisance/bug and is hopefully fixable with a software update (either to MacOS or to the LG monitor software).

    The lack of a button on the monitor is also a minor annoyance, as is the fact that it automatically goes into clamshell mode if I close the MBP to put it to sleep. I now have to remember the added step of putting it to sleep manually before I close it. Maybe this is intentional but not entirely desirable for someone not using the MBP in clamshell mode.
    All in all, these are minor and completely acceptable in the face of my MBP crashing when I unplug it from the monitor!

    Halfway there

    • Written by David M from South Haven

    The most critical parts for me: the color and the sharpness are unsurpassed. I would not be able to go back to my Cinema Display after spending time with this screen. Yet, I miss the design and build quality of my old monitor. There are plenty of details that point to sloppy design and manufacturing.

    The monitor cable does not sit snug, instead it sticks out a millimeter. The lack of ethernet and legacy USB ports is inexcusable, especially after using my old monitor as a hub.

    The volume is touchy as many people have pointed out.

    I've also had sleep/wake issues that have forced me to unplug and reboot my macbook.

    Using an i7 13" Macbook Pro 2016, I get stuttering when playing videos full screen when using Chrome.

    The light bleed when viewing black images is pretty bad.

    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.....

    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. :(
