    Very Disappointed!

    I have a MBP 15" late 2016 1 of these monitors. The problem is it is an unusable combination. I need to write documents that reference other documents to being able have both documents side by side is critical, i.e. cannot see both on the MBP’s monitor. Each time I plug in this monitor it is hit or miss if it will come on or if my machine will crash. Even if I can get it working it is only a matter of time before my machine crashes and I must start over. This was a horrible waste of my time and money. I have reached out to LG and have not heard anything back to date.

    Beautiful Display But Issues with Camera and USB-C Hub

    The picture quality is amazing, however I am having problems with the built-in camera and USB-C hub. I have a powered external hard drive, keyboard, iPhone, Belkin Ethernet adapter, and Apple keyboard plugged into the back of the monitor. Whenever I make a video call (Skype, Google Hangout, etc.) using the built-in camera, mic and speaker, they stop working and everything plugged into the back disconnects (though the display stays on). I've had better luck when the external hard drive is disconnected or plugged directly into the MBP. The closest WiFi AP is at least 15ft away.

    For $1k, these issues are a deal-breaker for me. Just as it was hard to go back to a non-retina display when the retina MBPs come out, it will be hard to go back to my Thunderbolt display, but I will likely be returning the monitor. Hopefully the versions with upgraded shielding won't have these issues.

    Not up to snuff

    Well it obviously works, but the little niggly things need to be fixed. As others have mentioned the sound level only has two options off and wake up the neighbours. Another one is RF interference from nearby WiFi access points. I don't have this problem as it's in another room. However, my screen goes haywire and takes the MacBook Pro screen with it when my iPhone is on the table near the monitor. It just keeps switching off and on and flickering until I move the iPhone away.

    All Good!

    Just got lg 27inch 5k monitor and its just great. Picture is amazing. Using with two 30inch cinema displays. Makes the cinema displays look very dated and not very bright.

    1. Connected to Mac Pro 2013. IT DOES allow 5k resolution! Just hold option key down when looking at the resolution options and you CAN select 5k. Text is too small to read but yes you can use 5k!!!

    2. No flickering. Router is far away.
    3. Connection to mac pro is using a usb c to thunderbolt 2m cable. 90 dollars in cabling.
    4. No sleep issues.
    5. Very bright.
    6. Great price for a 5k.
    7. There is NO reason not to get this monitor.

    Annoying technical issues

    The picture is great, however the display has some major connectivity issues with my MacBook Pro (late 2016) with File Vault turned on.

    - It crashes macOS when unplugged in clamshell mode. You can usually avoid this by opening it before unplugging the display.
    - The display won't turn on. You might have to plug/unplug the cable a few times until the display turns on. Make sure you're logged into macOS as well.
    - The sound volume is not calibrated. The range is 1 to 16 and 1 is too quite and 2 is way too loud. 3 is unbearable. You can kind of use option + shift to use go in 0.25 steps.

    I don't recommend buying this display, until Apple resolves these issues.

    Sound issue

    Sound on level 1 is so soft you can't hear anything. Sound on level 2 blasts right in your face. Something is definitely wrong.

    Potentially near perfection but flawed.

    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.

    Aha moment

    With considerable trepidation, I ordered the LG monitor for my new MacBook Pro. "It had to be a software problem" I thought, reading the highly variable reviews on multiple sites. For those of us "of a certain age," we have accumulated software glitches that even multiple clean downloads fail to catch. Having seen (severe) monitor problems with MacBook Pros with dual graphics capabilities in the past, I figured that an interaction between old, loaded at launch, persistent software and the graphics switcher would be the likely culprit. This has been the root of many of the solutions mentioned in the reviews. Having cleared both the "Launch Agents" and "LaunchDaemons" folders, and turned off the graphics switcher, the rapid screen "fluttering" I was experienced quickly abated. I also cleaned out a lot of old software, some of which I would rather have kept, but we'll see going forward if I can live without them.

    As others have noted, the detail at 5K is incredible. For these old eyes, it is a revelation, a savored boon with the granite of "the very old man" glowing red and alive.

    Bottom line, the monitor is cheaply built and does not work properly. The problems started right out of the box. Video switching with the brand new MacBook Pro 15" was hit or miss, either crashing the laptop or forcing a process of unplugging the usb-c cable, opening the lid, closing the lid, waiting a while, on and on.
    Then any peripherals attached to the usb-c ports on the back of the monitor would lose power when waking the laptop from sleep, forcing an unplug/replug cycle to get things to work.
    Last straw was the interference with bluetooth peripherals. If the laptop is placed close to the monitor, bluetooth items like a mouse or keyboard, lose connections in a seemingly random pattern, making them basically unusable. If the laptop is placed as far away from the monitor as the cable allows, the problem disappears. Was able to reproduce this behavior at will over a 3 day period, and Apple confirmed it was an issue. Then the news broke about the interference with routers.
    Not worth the price of a cheap Dell monitor.

    Unreliable, unusable, unstable, plagued with serious problems

    These displays cause random kernel panics on my macbook pro... even after a reboot both displays are still flickering... unusable... usually require several SMC resets to get back to normal. The USB hubs are also defective, every time I reconnect the monitors I have to unplug all of the peripherals, then plug them back in, before they will be recognized. No exceptions. Sometimes they also suffer from a brightness bug, where reconnecting the display sets the brightness set to 0 and it is nearly impossible to see the system preferences window you need to bring it back up. I have 2 of these monitors, both suffer from the exact same problems using the latest software. Do not buy.

    Causes MBP to Crash, crash crash

    Monitor looks good, and I don't have my router near it so I'm not getting that problem.
    BUT - it causes my MBP to crash when coming out of sleep all the time. I get 3 crashes per day if the computer sleeps while connected to the monitor.
    Called apple about 10 times and they want me to reinstall Sierra. Except we have FOUR computers and two monitors and it happens with all of them.

    Pass on this one - buy something else.

    Awesome Image, not so awesome performance

    I have this display. The display image is amazing, crisp clear picture. Brightness and color are fantastic.

    Down side is...

    Almost every day I have to re-log into my MBP because "Your Macintosh was restarted because of an error". When unplugging my external SSD from one of the USB-C ports on the MBP the LG display goes dark. I have to exercise (unplug/plug) the display cable and sometimes the Mac crashes so hard I have to hard power cycle the computer to bring the MBP back to life.

    The issues reported with the Audio are completely true. I have my computer volume set to 1 and if I hit the volume up key just once it's blaringly loud. Tonight it wasn't recognized in the Sound pref pane. I had to power cycle my MBP to get it back.

    Removing software from my computer that functions perfectly when the display is not attached is NOT an option. Sound drivers and Video drivers are necessary and I'm not going to cripple my MacBook Pro to use a display.

    Every day I go to the App store and check for updates in the hopes Apple can fix it. I keep launching the LG software in the hopes that it will show a firmware update for the display, but to no avail.

    LG's main focus is manufacturing cheap TV's, refrigerators, washing machines and dryers to market to stores like Wal-Mart, Lowes and Home Depot. They really don't care whether Mac users are frustrated or not. They sucker punched Apple, and us in the process.

    Frustrating that Apple would let something like this happen...

    Works as advertised

    Works as advertised with my 2016 MBP 15"

    Other then not having a 3.5mm audio output jack, the display is what I need.

    Terrible connection issues - doesn't play audio

    The display is beautiful. Bright and sharp. The problem is that when connected to the new macbook pro, it doesn't play the sound through the speakers. Occasionally if i restart i can get it to switch to the monitor speakers, but most of the time it just continues to play through the macbook. Selecting the output devices in the menu bar or system preferences does nothing. I'm past my return date, but would definitely return this if I was still within the date. Avoid this product until these issues are resolved.

    A lot of people have been having issues with these monitor staying connected with the new MacBook Pro. Especially when going in an out of sleep mode. Many people also have issues with the monitor going in and out while connected. I had the exact same issues. I was furious. After spending about $6K on the new MBP and 2 5K monitors, I could not get anything to work and spent many hours fiddling with it. After finally getting someone at Apple who was committed to helping me, we figured out the problem. These issues were caused by driver conflicts with programs I had installed such as "Duet" and "log Me In" . After removing the programs and removing them from my list of login items, everything is working beautifully without issue. It was a painful process but now I am loving the monitors. Find any programs on you machine that deal with multiple displays and remove them. Apple also recommended turning off virus protection if you have it. They said Apple never recommend using it on Macs.

    Hope this helps you. This is a great monitor if you can resolve the issues.

    Doesn't work with a Mac Pro!

    As I was going to use this with a Mac Pro, I discounted the laptop issues. After getting it delivered AND going to the Apple store to buy a Thunderbolt 2 cable and 2-3 converter for an extra $80 to connect it to the Mac Pro, nothing happens. Black screen. No sign of life. After extremely frustrating interaction with Apple Care, I did more online research and found this on the Apple site-

    "*Apple recommends that you use the LG UltraFine 5K Display as a second monitor with Mac mini and Mac Pro, as the display might not turn on until you boot into macOS. As a result, pre-boot features such as Boot Picker and macOS Recovery might not be available on the display."

    Great Picture but with Issues

    I use the LG 5K monitor with my new late 2016 13" MacBook Pro. Upfront the picture is gorgeous but there are issues which is just poor quality on Apple and LGs parts. Here is what you can expect.
    1. Volume issue - at the 1st volume level (minimum level before being muted) the sound coming out of the LG display is at a whisper. One level up and the volume is blaring loud and there is no way to adjust it to somewhere in between. This is a major design bug I'm hoping that Apple or LG fix via software or firmware update and soon - as from the user forums it seems that everyone is experiencing this problem.
    2. Thurnderbolt 3 port on the back of the LG monitor is flimsy. So if I move the wire in any way it affects the connection!
    3. Interworking between MacOS and LG monitor is buggy so things like awaking from sleep or rebooting result in black screens and weird behaviors requiring another reboot.

    I Must Have Got the Good One

    I was pretty scared reading everything in the press and in the reviews here after I ordered this display to use with my new MBP. But apparently, I got the good one. ;-)

    I'm sitting right next to a WiFi router and am seeing no flicker, no black screen, no signs of interference at all.

    My MBP goes in and out of sleep plug into, plugged and unplugged from the display without issue.

    Sound is great. Controls work great. Hinge and adjustment post feel solid yet easy to adjust and hold firm.

    The outer case design is beautiful and solid too. It's plastic but solid plastic with a bead-blasted texture to it. Looks as great from behind as it does up front.

    And, of course, the screen image is amazing - Cinema Display level amazing, and beyond. Colors. Pixels. It's pure digital joy.

    Count me as 100% satisfied!

    Screen goes black intermittently

    While the display panel itself is just as good as Apple's own 5K iMac screen, the rest of the monitor feels like Dell on its worst day. It's plasticky, unstable and for some strange reason goes black every now and then. The MacBook would disconnect when the screen goes dark, causing a few seconds freeze as the Mac try to reconfigure itself, followed by the screen switching on again, and therefore another few seconds freeze of the Mac. Occasionally the monitor would freeze my MacBook entirely, and the only way to get it out of its coma is by unplugging the USB-C cable altogether.

    Under normal circumstances I would have just returned the monitor for a refund. But the lack of choices (as Apple has chosen not to release a display of its own) means I'm stuck with this flimsy, cheap looking and poorly engineered product for now.
