    Bought July 30th, and didn't use it for the first two weeks. Now that I have been using it for the last two weeks, it has blanked out on me 5 times. It's getting more and more frequent. There is no power button on this so you can't power it on and off, the only choice is to pull out the plug and hope that causes it to flicker back on. I thought it was only when the computer went to sleep, but now it just happens while working. Apple top tech suggest shutting down the computer to get it to work every night, LG tech suggests change the power outlet it was plugged into. Forget it. Don't buy this monitor. This or the B version. Junk. LG tech support is a joke. Run away Run away. Mine is going back today.

    Leads to my audio constantly buzzing

    Ever since I started using this monitor I have crackles, buzzes and hums on my audio equipment as long as I am near the monitor. Even using my iPhone with some headphones near the monitor will lead to a buzzing on it. Great picture quality though.

    Worked ok for 16 months, now failing with crashing MacBook Pro

    I am working with a 2016 MacBook Pro 13 inch and all worked ok but now constant crashing when reconnecting after sleep mode. Restarts the computer with all the issues. Flickers for some time on/off after restart and then works until the next reconnect.
    The sharpness is really great, colors are very good, however, it could be brighter. It also had issues before with turning black while working and coming back immediately. No normal USB ports, only USB-C which means I had to buy additional adapters for standard devices that are not even offered as USB-C, yet. It is a shame that Apple is selling this for the high price but not offering any support and does not care for the issues. I would highly recommend staying away from this display.

    Still crashes MacBook Pro (2017) nearly every time it sleeps

    The monitor looks great, good real-estate, clear text etc. But it frequently crashes my MBP. If I go to lunch, I come back to a post-boot login screen. Can't believe this is still happening. No updates have fixed.

    Beautiful Panel but Terrible in Every Other Way. No support.

    I have two of these LG UltraFine 5k Displays that I use with a 2016 MBP.

    The good:
    -The panel is beautiful (I believe it is the same used by the 27" 5K iMac).
    -The built in camera and microphone work.

    The bad:
    -Thunderbolt 3 only (wont work with a PC. Apple only)
    -Causes sleep wake failures and shuts down my MBP. Apple replaced the logic board on my MBP because of this issue and with the new logic board I still experience the same problem when both monitors are in use. Really disappointing because Apple says my computer supports two of these monitors...I would not spend $2,000 on incompatible monitors...shame on Apple and LG for selling this garbage.
    -Does not support portrait mode.
    -Speakers are unusable. They crackle on both monitors.
    -Ugly design.
    -Glare from glossy screen.

    Apple should make a Cinema Display again so that their customers can avoid this nonsense.

    Poor Picture Quality, Glitchy Functionality, Limited Flexibility

    While this display can have a nice image, and it can be convenient, it's rarely so. The display suffers from severe image retention issues, leaving ghost images of your recent windows all over, the USB ports on the back are slow (USB 2.1, even though they use a USB-C connector), and have frequent issues, the display is often glitchy when restarting/waking from sleep/being plugged in. There also isn't a way to use an HDMI or Display Port cable with it, so external GPUs aren't an option, and you can't plug in an additional source. All this from a display that's significantly more expensive than the competition.

    Avoid this display! It's defective

    This display is defective and has not been fixed by LG or Apple. It's prone to flickering (left and right parts of the screen on and off) making it unusable. It's not the cable as I switched this out with others.

    Just avoid it and settle with a Dell 4K or like It's not worth the hassle.

    Failed after 14 months

    The fan on this monitor failed after 14 months, 2 months after the manufacturers warranty expired. This is an expensive monitor to fail just 14 months after it was made.

    Terrible Monitor

    I purchased a 2017 Macbook Pro with USB-C ports so I needed to find something to replace my really nice, lovable, Apple Thunderbolt Display, which worked super well with my old Macbook Pro.

    This new UltraFine 5K Display is really awful. I just purchased my 2nd one, only because the display itself is closest to what I had with the Apple Thunderbolt Display. The reason it's awful is that even though my 2nd one is the latest and greatest version, it still flickers. Brand new, and it just randomly starts flickering. No router nearby or anything like that. Secondly the thing I detest is the sound. It went backwards in technology about 20 years. The volume increments are laughable, and the sound quality is just awful.

    The display itself, is nice to look at. That's it's only redeeming factor. And if this thing didn't flicker on me, I'd probably give it 3 stars since I can always just purchase a good quality Bluetooth speaker. However, on my previous Apple monitors, I could always depend on them having really great sound.

    new MBP + 2 monitors = no good

    I don't know if it's my new MacBook Pro or if it's an issue with LG's monitors, but I can't plug two of these in to my MBP as promised and have it just work (and yes I'm plugging each onein to a Thunderbolt port on either side of the keyboard directly, not daisy-chaining them). If I restart after plugging them in, then they work, but if the laptop goes to sleep, only one of the monitors wakes up and I have to restart again to get the other one to respond. So disappointing. Also, the picture quality of these monitors is great, but the build-quality and design of these monitors looks like junk next to my MacBook Pro. They wobble a lot, too, just from typing. It's sad that these are probably the best available right now.

    Great picture, bad everything else.

    The colors, contrast, and clarity are phenomenal. Best I've ever experienced in a monitor. HOWEVER, the picture quality does not outweigh the glaring negatives about this product. To start with a big one, when waking my mbp from sleep w/ the monitor plugged in, there's about a 50/50 chance that my mbp crashes. Ridiculous! Another negative is the painful lag when working in adobe programs or sketch. My fully upgraded machine suddenly slows to a crawl when I'm plugged into this monitor. Apparently Apple didn't give the mbp's enough guts to handle their own monitors. The last major negative is the frequent static/fuzzy screens that flash on and off when waking up my machine. On the flip side this usually indicates that my computer isn't going to crash, however it takes about 30-45 seconds for the monitor to display my desktop after strobe-like static flashing.

    TLDR: Great image. Horrible user experience. Monitor must be unplugged at all times when not using your computer or else risk a total system crash and reboot.

    Don't expect much...

    This display is OK for what it is, but don't expect 5K resolution, and don't expect the internal USB-C hub to be particularly useful...
    I have had this display for nearly a year, and used it with two different 2016 MacBook Pro's (and three different motherboards between them). None of the MacBook PROs have ever offered me a 5K resolution option. The "default for display" is 2560x1440 and no scaled resolution better than 3200x1800 is available. This doesn't bother me so much as 2560x1440 is pretty adequate. However, more problematic is that the internal USB-C hub is terrible. One of the basic utilities of this display is that it can offer one-wire-docking for your MacBook, and if you're on a wired network this is accomplished by having a USB-C -to-ethernet adapter (I'm using Apple's) plugged into the back of your monitor so that you get networking when you plug your mac in as well as video, mic, speakers and camera. But if you actually *use* the network, the LG USB-C hub can't handle it. For me, this evidences itself in video conferencing. I can get on a video conference, but generally after a few minutes the network drops off, then the MacBook doesn't see the LG's camera, microphone or speakers anymore. I recently sent the LG display in for repair in the hopes of addressing this issue, but it has returned unchanged. (And the notes on the repair ticket don't mention the problem, instead saying I sent it in for "video problems". Apple takes no responsibility for this display and LG Tech support is not particularly useful.)

    Waste of good money - non-responsive customer support

    I have struggled with this monitor for several months to find a cure for the unstable and at times disappearing cursor or mouse pointer associated with my MacBook Pro 2016. The cursor actually works on the MacBook screen but not on the LG 5K display. I have tried LG and Logitech software, etc. and it is clearly an LG display problem. I have tried different mice brands, with the same result. I get no response from LG service when I try to contact them. It has made the screen virtually useless. I have now purchased a Dell 4K display that I use with no problems whatsoever.

    This thing is Junk

    Monitor will not turn off or sleep. Unplug my new 15 Macbook pro with Touch Bar and the monitor blazes bright white with no way to turn it off. Resolution os good its just not a functional piece of hardware.

    Great Display, but hangs my Macbook

    Apple thinks it is supposed to work great with the MacBook Pro 15 as seen in the launch keynote, but I can't say that's true. My MacBook Pro 15 freezes almost everytime I connect the monitor. Mind it, that I am using the OTB cable, I have tried all the video memory refresh tricks, Downgraded to MacOS sierra to see if I can correct it but NO. My only way out is a force restart. It's just annoying. When it works, the display is crisp, clear. But the glare, ARRGH. Dell does a better job at making work monitors.

    Do not buy!

    After a few months, the displays suffers from a major image retention problem. LG support states that this is normal and refuses to do something. Therefore, I really can't recommend to buy this display.
