    It would be amazing, if it would only stop flickering.

    I waited until after the shielding issue was resolved. I even moved all wireless tech (save for the 13" MacBook Pro) away from the monitor. My unit still flickered and pegged the MacBook CPU close to 100%. I did everything Apple tech asked me to to debug. They blame the monitor. This was December manufactured, with black dot on label, so shielding retrofitted. Badly it seems. I have placed a second order. Fingers crossed that works out and I can update the review to five stars.

    Would be a beautiful thing if it worked reliably

    Had seen these in my local Apple Store and was blown away by the image quality (it’s absolutely stunning). I initially held off buying one based on previous bad reviews. However, once the shielding issues were reported as fixed I decided to give one a try. Three days later, I’m returning it, as it keeps disconnecting itself randomly from my MBP. The screen goes black, the connected hard disk gives a disk not ejected properly error and the all windows revert back to the MBP (just as if the monitor had been unplugged). I have had no such issues with either my Apple Thunderbolt (Thunderbolt 3 to Thunderbolt 2 adapter) or Dell (USB-C to DP cable) displays. The LG’s S/N started 0701 (Jan 2017) and the circle symbol was present on the box (indicating a unit to which shielding has been retrofitted by LG).

    Mixed feelings

    This display has unbelievably crisp picture quality. Build quality is also good (better than a typical LG display, at least).

    However, the image retention / ghosting / burn-in effect is terrible. It took me a while to realize what was happening — it's so bad that at first I thought it was a transparency setting in macOS itself.

    It's also been EXTREMELY flaky with my 2016 MacBook Pro. Minutes after plugging in, my CPU temperature and fan speeds skyrocket, even when the computer is totally idle. Unplug the display, and after a few moments the CPU/fans go back to normal. The monitor itself also pumps out a noticeable amount of heat.

    There are also frequent issues when plugging in or unplugging the display from my MacBook Pro. The screen glitches out, sometimes the camera doesn't work, other times it won't wake from sleep and completely bricks my laptop and I have to force restart it.

    (I know there are reports that being near a WiFi router can cause these issues. However, I'm very far from the nearest router so I don't think that's the root cause.)

    Even though the picture quality is great, I don't think this monitor is a good purchase. It's just too expensive given the constant issues.

    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...

    if it didnt have issues it would be good

    The screen itself is nice, color is good, but it is a headache owning it.

    Reasons not to buy this monitor

    1) Every time I unplug my mac book pro with touch bar from the monitor while in clam shell mode it causes my mac book to crash.

    2) sometimes when using the product the USB ports will just shut off

    3) sometimes when using this monitor the screen will just turn off

    4) if the mac book pro with touch bar while in clam shell mode comes into contact with the bare metal it will put the mac book to sleep. This means you have to put some paper to something in between the monitor and the macbook so they do not touch.

    Best and Worst Monitor I've Owned

    Beautiful monitor that is nothing but trouble. Mac crashes at least once a day when waking while it's connected to the monitor. I have to remember to unplug it before trying to wake it up every time. I don't know if it's the MBP, its stupid touchbar, or the monitor, but I can't remember ever owning a setup this unreliable since Windows 98 was a thing. Would happily give this 5 stars if it "just worked".

    Fantastic image; 2nd best stand; good speakers

    I'm switching to this from an Apple Cinema 27" display. It's really a great display: the image quality is outstanding. Brilliant. Clean. Crisp.

    The speakers seem just as good as the (USB) Displayport 27" Apple Cinema display I had. I'm using it with a 2016 MacBook Pro Touchbar.

    The stand is really pretty good; it does allow raising and lowering it, and has a slight tilt adjustment. It was packaged very similarly to the Apple Cinema display (which I just repackaged after ~5 years of use).

    The black bezel with my space-grey Macbook Pro really matches stylistically, too.

    Plug and Play right out of the box

    Exactly what I expected. Simple and understated with an incredible display. The aspect ratio is perfect especially if you run windows as a virtual machine.

    Almost Perfect - What's the fuss about from others????

    Crystal clear, true 5k, perfect companion with my Macbook pro 15 inch, and with the most recent update from Sierra 12.4, no delays from brightness control.
    I now use Lg 5K as my primary display when my macbook pro is docked. Needless to say, nothing I expect more from this almost perfect product.
    In the future, if autobrightness could be added to the screen, it would be perfect.

    Most satisfied costumers won't come here and write a review. Get a life complainers!

    Revised version usable but flawed

    The addition of WiFi shielding makes this display usable, albeit with a couple caveats:

    1) I crashed my mac when unplugging the monitor while it had its lid closed.
    2) Backlight bleeding/glow is a bit more than I expected, though totally passable.

    On the positive side, the monitor has incredibly vivid colors and it's amazing to have a desktop sized retina display. So, I will be keeping mine. Hopefully Apple can fix the crash and this monitor will be rock solid.

    I have had the monitor for 2 months. It has been nothing but problems. I sent it back to have the shielding fixed. However, it still has issues with the USB-C connection. Almost every time I hook up my Macbook Pro, it won't properly wake up. I have to reset my Macbook everytime I connect it to the monitor. Save yourself the headache.

    Everything I have been waiting for

    Lets start out by saying its simple, with clean lines and has a smaller footprint than former Apples monitors. Its not up to the Apple style but the image is supper. The first monitor I have found that has perfect scale. I have come to love this monitor. It was easy to mount and comes with the mounting hardware.
    I have it paired with a new MacBook Pro

    Better than expected

    I admit I was worried about the performance of this monitor based upon the reviews….but it was the only option to work with my new Macbook Pro using the new Thunderbolt 3 connection. All worries were put to rest when I set-up the monitor today. The monitor set-up required nothing more than plugging it in. The monitor looks good and operates flawlessly (i.e. stand adjustments, picture, sound and camera).
    I just wanted to let others know there is nothing to be worried about provided you are connecting the LG monitor to a newer MacBook Pro.

    LG 5K & WIN10 under Bootcamp

    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.

    Wish it was an Apple designed product, but overall I'm satisfied...

    From a design standpoint, I wish this was an Apple product. The design is ok, not great. But from a usability standpoint, I'm satisfied. My main monitor is a NEC PA322HD, a highly color accurate reference monitor I use for high-end color correction and pre-press accuracy. But for sitting at my "writing" desk I needed something smaller, yet still bigger than the 15" display on my 2016 MBP. Got the new, fixed, version. So far no issues.

    (Please Apple, make your own displays with your own brilliant industrial design. As a trillion dollar company, not every single product has to be a profit center.)

    It is sad that Apple exited the display business. This LG display looks hideous on my desk. Aesthetics still matter.

    Beautiful display when it works

    What a disaster this monitor has been. Mine came with the Wi-Fi shielding issues and the way our office is configured there's very little room to place the router further away, so the monitor flickers or sometimes just blacks out. Then often times the monitor won't wake from sleep and worst of all the BMP will freeze up when connected to the monitor causing you to have to reboot the MBP. There are other issues as well, but those are the most egregious. I purchased the monitor from Apple and they won't return my emails or calls and when I call LG they want me to ship it back and go without a monitor for 2-3 weeks so they can fix their defective product. Remember what it was like when Dell equipment and Windows had problems and both companies would say it's the other's fault... well welcome to the new Apple and LG.

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

    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.

    Bottom line, this monitor is not good

    I have really tried my best to work with the problems with this monitor, but ended up returning it. It just has too many issues. The picture quality is nice, but if it wont work right, its useless, especially for the price LG is asking for it. I expect, for $1000.00 this machine would be great with no issues at all. Mine has a sound problem, blue and red hues are off, and also would shut off completely all by itself, at random.
