    Brightness constantly drops to zero on wake

    Although the monitor looks great and has good color, it's brightness drops to zero whenever I wake my MacBook Pro (2013). The backlight is completely off, although the faint image of the desktop is still there. This means that now my wake up sequence involves opening the Displays system prefs panel, squinting as I move the mouse around the darkened screen trying to locate the brightness slider, then sliding it all the way back up again. It's tedious. It shouldn't happen, and it negatively impacts my productivity. Hopefully this is something Apple can fix from it's end fairly quickly.

    Beautiful display. Works perfectly. No issues whatsoever!

    Bought this monitor despite the bad reviews since the RF issues have been fixed and the bulk of the bad reviews spawned from that. I've been using it for about a week now with zero issues. I have it connected to my 2016 MacBook Pro 13" with a touchbar via the thunderbolt cable that came with the monitor. No wake up issues, works great as a hub ( I don't care about the slower speeds ), fantastic image quality and the brightness is simply amazing. 500 nits just like my retina MBP display so the transition is seamless. I am glad that I pulled the trigger and didn't let the bad reviews dissuade me. I will say that the people that applaud the speakers have not heard decent speakers. Sure, they are better than my MacBook Pro speakers, but I wouldn't call these speakers good (loud doesn't equal good...) I am using Audio Engine A2+ hooked up to the back of the monitor and they sound amazing.

    Defective Display, buyer beware

    I bought this display just a month ago and goodness, it has problems. The problems start by everything I plug in USB, does not recognize, to random screen blankness. Sometimes, at random, the screen will just go black. I called LG and they have no solution. This is not an Apple branded display, yet sold by Apple, so I trusted that it would be good. It clearly, clearly, has issues.

    Beautiful but defective monitor.

    The display is very beautiful and easy on my eyes. The idea of having a USB-3C bus where I leave my backup drives and other devices plugged in and just have to plug in my laptop is a great idea. The problem with this picture is that my unit is defective. It hangs my Mac sometimes when I plug it in or when Night Shift kicks in. It sometimes comes up with a super dim display with no way to increase the brightness in a well lit room. The USB bus fails and requires me to disconnect my devices and reconnect them to get the ports functional again.

    So the question is "Is this a defective unit or a defective product?" The jury is still out, but LG says that my unit functions as expected after I confirmed the problem in the Apple Store with a floor model and after I shipped it back to LG three times for repairs. I hope your mileage is better than mine. Oh and by the way, my monitor got the extra shielding the first time they repaired it, so the original WiFi bug that was affecting everyone was not my problem.

    I bought this despite the bad reviews and am sorry I bought it. My biggest problem is the USB-C ports in the rear of the display. They only work 50% of the time, sometimes I plug my USB-C gear in and it doesn't recognize. I called LG Support, which was a waste of time. They told me that they are working on a firmware to fix it, and should be ready sometime in 6 months. I didn't pay $1299 to have something ready in six months. This display definitely wasn't ready to be debuted and if Steve Jobs was still around he would be very disappointed.

    1 Star.

    Despite little issues, satisfied overall. Easy to use with no serious issues for me on the single cable USB hub/monitor/charging connection to MBP15 2016.

    Little disappointments:
    -a block of four pixels were stuck on out of the box.
    -Intermittently the monitor does not come on if the cable is plugged into the Macbook with the thunderbolt symbol facing down.
    ( I just take it out and plug in the other way up.)
    -backlighting not as uniform as I would like
    -as an older person, I would really like a physically larger 5K screen (30 inch) so that I could work more comfortably will small font sizes
    -it's disappointing that the screen won't charge USB devices when the macBook is not connected
    -there are still some issues with volume control of the screen speakers

    little pleasures:
    -I haven't seen a better screen
    -one cable for everything is even handier than the previous thunderbolt plus magsafe.
    -The height adjustment allows the macbook to be open directly under the screen, so I can use both screens
    and the macbook keyboard, trackpad, touchbar directly in front of me without swivelling.

    Screen is great, everything else is bad

    Screen is gorgeous, but integration with macOS is terrible.

    - Volume controls are extremely sensitive
    - USB-C hub just does not work: 80% of the time accessories will not re-appear after you connect your MBP

    Stand is unreasonably large.

    Poor performance, poor customer service

    First I will say that the LG display is bright and sharp and makes pictures look beautiful.

    However it is very disappointing as a display for a MacBook Pro. To begin, it takes a long time, often a minute to "wake up" when connected to the USB-C port on the laptop--maybe that's the laptop's fault.

    Periodically during operation the LG display will go black. (My office space, like many, contains multiple wireless routers, but none within 8 feet which would exacerbate a known defect with shielding in the LG display.) After 5-15 seconds the display will usually resume, or not. Occasionally the it will remain nonresponsive and it is necessary to disconnect the USB-C cable, wake the laptop and then reconnect the USB-C cable. On at least three occasions after the LG display went black, my laptop crashed and rebooted.

    Beyond this, the customer service from LG is very disappointing and not at all what might be expected from Apple. Trying to get the problem corrected has involved many visits to the LG website, web chats, emails that don't get replies, and talks with LG representatives, who freely admit that LG has not fixed the problem. Apple should find a better partner. The current remedy is to ship the display to an LG service center where a technician will add shielding and return it 7-10 days later.

    I cannot recommend this display and would advising waiting until problems are corrected.

    Swapped LG 4K for LG 5K for my new touch bar 15" MBP

    Having just upgraded from a 2010 15" MBP with a Apple Cinema Display to the latest touch bar 15" MBP I chose the LG 4K display.
    I let the reviews sway me towards the LG 4K from the LG 5K.
    My wife (we both use the same computer) was not happy with the 4K as it was slightly smaller than our old Apple cinema display.
    So I was happy with Apple's 14 day return/replace option. They happily changed over the LG 4K for the larger LG 5K Display. Straight out of the box the new LG 5K Display plugged straight into the new MBP and worked perfectly. The new display is absolutely fantastic and a joy to use with the extra real estate, clarity, default colour and when used with a new Apple Magic Mouse 2... Wow!!
    This is my 10th Apple Mac, started with a SE Mac and a 19" Radius Monitor in the 80s and this new technology is fantastic.
    I think LG must have solved all the original faults with these displays so don't let negative reviews put you off.
    As for complaining about the Energy stickers on the front of the new display leaving smudge marks... Hello, the stickers only have 'sticky' on one half, just lift with finger nail, pull and no smudge. I have been retired for years and have no allegiance to any company.

    Great but (sometimes) Glitchy

    Moving from a 2560×1600 display to the 5120×2880 UltraFine 5K is amazing! Although I prefer the 16:10 aspect ratio, it is wonderful to have the retina resolution on a primary display!

    The colors are pretty good (not quite Eizo-level, but better than most). The glossy-finish is a bit annoying, but it's not the most reflective. It's not quite a true 10-bit display (Frame Rate Control is used to create the illusion of 10bit colors with the display's native 8-bit hardware).

    I love how dim you can set the brightness! When working in a dark environment, it's great to be able to drop the brightness all the way down to ~10cd/m^2 (or less)!

    macOS 10.12.4 thankfully fixes the lag when adjusting the display brightness from the keyboard (and, sensibly, removes the need to hold the Control key when hitting the brightness keys on an external keyboard). 10.12.4 also seems to have resolved some performance issues such as the system crashing when Display Mirroring was enabled with the 5K and external displays of other resolutions.

    The webcam is sub-par and angled in the wrong direction – I would rather they have left it off as I use a better-quality external one. (I keep the display at the minimum height and at 90º. However, in that configuration, the top half of my head is above the camera's field of view.) (720p is an acceptable resolution for a webcam, but the aperture is pretty narrow and those 720p images are subpar compared to 720p images from most external webcams which have larger aperture lenses and larger sensors.)

    At the end of the day, working on a 5K retina-class display is a amazing! This is an early adopter's display to be sure, but my list of gripes has been steadily decreasing with each update to macOS 10.12.

    Working beautifully with MacBook Pro Retina 15" mid-2014 - at full 5K

    Received this monitor today. I have a mid-2014 MacBook Pro Retina 15" with the NVIDIA GT 750M with 2 GB of graphics memory. I have connected the monitor to my MacBook using an Apple Thunderbolt 2 cable and an Apple Thunderbolt 2 to Thunderbolt 3 (USB-C) adapter. Everything is working great; monitor, USB-C ports on monitor, speakers, microphone and camera. What is more, although Apple state that my machine should only run the monitor at 4K it in fact runs it at full 5K resolution at 60 Hz! The monitor is 1m from my AirPort Extreme router and so far no glitches or other problems so it seems they have addressed those issues too. My one gripe is that the granularity of volume adjustment is not so great. Once you get to just 2 bars of volume it is plenty loud and going any higher starts to bring a little distortion. It would be better if there was more granularity to the volume control.

    Overall at the moment I am very happy with this monitor.

    Greate picture quality BUT... does not WORK AT ALL!

    Here's just a short list of my issues with this monitor I am going to return asap:

    - (probability: 60%) When connecting the USB-C cable to MBP, the screen turns on but there is no power, MBP battery does not start to charge. Workaround: disconnecting and reconnecting the cable several times.
    - (probability: 50%) Additionally on the monitor connected peripherals (keyboard and mouse) will not get detected once the USB-C cable is plugged into MBP. The monitor will correctly turn on but peripherals won't work. Workaround: reconnect peripheral cables
    - (probability: every now and then) Screen flickering. The screen shortly flickers 1-2 times, then runs fine again. This happens ~ every 10 minutes.
    - (probability: 10%) When connecting the USB-C cable, the monitor turns on but just with a brightness of ~ 30%, way too dark. It did not recover after reconnecting the cable multiple times. Workaround: Adjust brightness in System Settings -> Monitors

    All-in-all: A completely unstable product! Did LG ever test this thing? Their QA-team must have been on vacation while this product got launched.

    Best Display I've Ever Had!

    I bought the LG Ultrafine 5K display at the end of March and have had no problems with it. The screen image is outstanding. My S/N starts with 0701 (Jan 2017) with a circle on the box (indicates shielding has been retrofitted by LG). I have a 2016 MBP 15” TB, Mac OS 10.12.4, with a single HooToo HT-UH010 powered USB3 Hub plugged into the display using an Apple USB-C to USB Adapter. I had the hub before getting the display as I have 7 devices attached – I couldn’t hook them all up to the display without the hub anyway. The only cable to my laptop is the single TB3 cord that came with the display. Nice to have one cord plugin and not have to fuss with adjustments of any sort. Never had a problem with wake from sleep or not recognize USB3 devices – everything working on my system. If you’ve used other USB3 hubs you may have encountered a few that need to be unplugged and re-plugged to be recognized after sleep – I think this may be a USB3 issue not a display issue. I’ve never had a crash in the 2 weeks I’ve had the display. The speakers are fine for monitor speakers, but don’t match free standing computer speakers for sound (as I expected). They are good enough that I haven’t found the need to add a set and give up the desk space they require. I you want to listen to music, I’d Airplay them through another system (as I do). The volume does jump a bit from lowest to next level, but that hasn’t bothered me as there are usually volume controls on whatever app I’m using. The camera gives good images and it is nice to not have to open my laptop from clamshell when I use FaceTime. You must designate to use the display for both sound AND video in FaceTime – the default is to use the built-in camera and speakers in FT and it doesn’t change automatically when you plug in the display. Dimming works just fine from the keyboard in OS 10.12.4 on my system. The build quality of the display is fine by me. No quarrels at all. I’m not looking to make a statement about my taste with my display. To tell you the truth, I don’t even see the thing – it blends into the background and is super easy to adjust position. If you want to use this as a 5K display, then you need to have a mac device with TB3 ports (MBP 2016 only at present). If you use a TB2 -> TB3 adapter, it will run in 4K instead of 5K which will not be native resolution and therefore not as sharp. You could wait until Apple makes a new stand-alone monitor in 2018 or 2019, but I needed this for work now. I have no image retention/ghosting/burn-in effect on my monitor – I’ve set my monitor to sleep at 15 min of inactivity. I’ve had no laptop temperature/fan speeds issues or noticed any unusual amount of heat from a display of this size. I have had no occasion to force restart any of my devices, laptop or the monitor. If you have a system configured like mine, I suspect you’ll be very happy with the LG Ultrafine 5k. Never had or seen a better display. Not giving mine back.

    Love this monitor!

    I love this monitor, and it works as advertised right out of the box! Color balanced it for wide gamut, and it's even better. It's amazing having a "Retina" display at this size. I'm a developer and my wife is a photographer, and while we've only had this monitor a short time, it's worked perfectly. Read a lot of negative reviews and was concerned, but my experience has been very positive, and would definitely recommend. Purchased before the price increase, so even better. I've not had issues using with my 13" MBP with TouchBar except a few lags with large images or rapid scrolling. Haven't had much time using with our 15" MBP/TouchBar, but expect to be more than adequate. The aesthetics don't bother me, understanding it's a third party monitor, and doesn't detract from the experience of using the monitor. Yes, the sound could be better, but is fine for iTunes or Spotify, and certainly for FaceTime; a little mushy overall, the highs are not clear, and a little bass heavy, but not nearly as bad as many reviews indicated. The larger 27" screen, 5K resolution, and built-in camera and speakers were the deal makers in choosing this monitor over the smaller 21.5" 4K monitor for me.

    Excellent addition to new MacBook Pro

    I use this display all day at work in my office, along with my 15" MacBook Pro. The build and display quality are very high, and so far (after several weeks) the integration with the Mac has worked flawlessly. I have had no issues, it truly is plug and play. The fact that it is just a single cable to connect to my Mac makes using it that much easier. As with everything else on this display, the speaker quality is Bose-like in terms of crystal clear loudness. It really is amazing all that they were able to pack into this monitor, I can recommend it without reservations.

    Don't let the negative comments discourage you! This thing is INCREDIBLE!

    I was very concerned about purchasing this monitor... and I ended up buying a viewsonic... Which had a nice resolution, but didn't have the Retina display! It was simply not good (color, sharpness, controls, etc.)

    I decided to buy the LG Ultrafine 5K monitor... and let me tell you, this thing ROCKS! The image on the screen is as good if not better than my MBP with Touchbar. The speakers are SPECTACULAR! And the camera is FANTASTIC! The build quality is excellent... and the fact that there are no buttons... everything is managed through the software, it just the FUTURE! TODAY!

    I highly recommend this product. It works beautifully! All the negative comments are from previous version of the product and several software updates ago. They don't apply any more! Works perfectly!!!

    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)

    Horrible! Stay away from this LG Display

    Bought this a few days ago and ended up returning it. I could not stand the problems with this LG Display. From USB not recognizing, to random turn offs, I ended up just returning it back to Apple and buying a used Thunderbolt Display. The picture quality was superb of this display, but the issues were not justified to keep it. This display has many problems and should have never been released to the public.
