What People Are Saying

Rated 4 out of 5 by from Simple single connection to Macbook Pro On a daily basis, I switch between use of the Macbook as a laptop, and connection to the LG 5K monitor with the laptop closed so I can see two large windows side by side. Perfect for that, but, had to get a bluetooth keyboard and bluetooth mouse (hard to find, most mice now 2.4GH with dongle), to get the monitor and mouse to synch correctly every time. Sometimes have to wait briefly to wake the monitor. Very satisfying display, and screen size and proportions perfect for two large windows up on the screen.

Rated 5 out of 5 by from 100% RECOMMENDED! I will make this short and sweet. I have used many high performing monitors in my day and especially as of recent as I was deciding on what I should use for my primary monitor. I just purchased the UltraFine 5K today and calibrated it with DisplayCAL. The results? 100% sRGB (I've never seen 100% before). 87.5% Adobe RGB. 99.8% DCI P3. This monitor is INCREDIBLE. Ignore the bad reviews. I'm in love at how accurate and uniform this display is. THANK YOU APPLE AND LG!

Rated 5 out of 5 by from Amazing picture quality with a meh design I got this monitor for my 15" MBP 2016 and I love it, the design is nothing near the Thunderbolt Display or iMac but the display resolution is as good as my laptop and that's great. The integration of this monitor with MacOS Sierra is perfect and I didn't have any crashes during the installation or problems with my AirPort Extreme. The speakers are pretty decent for a monitor and the webcam works pretty well. I just wish that LG used a design similar to the 27UD88 with aluminum finishes for this monitor.

Rated 2 out of 5 by from When it Works its Great Monitor has a ton of software issues. First, you have to plug it in while the macbook is awake or risk it freezing the macbook. Second, must unplug it in sleep mode for the same reason. When plugged in the monitor one screen always starts off with the brightness on dim. But if you do the work arounds for these issues the picture is gorgeous. The most beautiful monitor on the market in terms of screen picture.

Rated 1 out of 5 by from Terrible! I am using the monitor with my brand new MBP 2016 13" with the TouchBar. The picture quality is fantastic; however; there are obviously tons of other problems with the monitor. In my case, when the monitor is connected to my laptop in clamshell mode, it crashes the laptop and none of my wireless accessories work on restart. The only solution I have found is opening the laptop, connecting the monitor, and then closing the lid once the display comes on. Likewise, if the laptop is disconnected while in clamshell mode, when you reopen the computer, the TouchBar is on but unresponsive and the screen goes black, and you have to restart the computer. As with the initial connection, if you open the laptop before disconnecting and then close it, then the laptop does not freeze when it reopens. Hoping firmware/software update will eventually resolve this, but its pretty ridiculous that things like this weren't ironed out before the product was released. Really wish Apple was still making their own displays.

i was confused by the apple store sevicer to use this for an mac air. so do i have any solution? or is there any way to change the output thunderbolt3 into HDIM without any influnse of the display?

Asked by: tq00i8e
The MacBook Air is not supported on a 27" display, because the MBA doesn't have the resolution support. Native resolution for an Early 2015 MBA would be 1440x900, for external display support it can handle a 3840x2160 which would be 4k.This 5k display is 5120x2880. So MBA is NOT compatible.

How do you get the flashing to stop, it's really annoying.  It only happens once in a while but it must stop!!!!

Asked by: MacUser1972
We regret the inconvenience you have experienced with this monitor. It is uncertain to what is being referred as flashing. Is this the screen changing brightness, or is it related to an indicator light blinking? Please contact our Customer Interactive Center at 800-243-0000 for assistance with this matter.
