What people are saying

Rated 1 out of 5 by from Failed at not even 3 years old While the picture quality has been very good, form a usability and durability view this screen is extremely poor. I have always used it with the out-of-the-box cable and still, many times it would not connect properly and now, after 2 years and 10 months completely failed. Only power supply but no more picture. With not even a single button, there is no reset or trouble shoot. I just get an error message, that I the used cable is not supported? Also tried other supported cable, same error message. Service is not helpful at all would recommend to have repaired and send in at my own cost. Would be ok for a $200 screen but not this. I don't care too much about the design, yes, larger bezel on top is odd but otherwise it has a clean look. Sound issues as described by others, either too low or too high volume. Running it with both a 2016 and a 2019 13" MacBook Pro.

Rated 1 out of 5 by from Was great until it stopped working after 14 months Beautiful monitor that worked almost flawlessly with my 2018 Macbook Pro. Occasionally the screen would flicker back for a few seconds every now and then, but it was a pretty rare problem. Then about 14 months after purchase (just past the end of the warranty period) the screen flickered back as I was adjusting the height, then went totally black and never came back. The LG-approved repair place in my area now wants $600 just for the price of the replacement "mainboard."

Rated 3 out of 5 by from Good monitor no controls I really like the display, clean clear and the USBC connection works great with my Mac Book Pro. I am very happy with the color, sharpness and ease of connectivity \. But with no controls it makes it really frustrating. I cannot find a way to make the thing stop blinking short of shutting off the power it goes in to a "sleep mode" that is annoying. After a few mins no mater what screen saver settings I have it starts blinking a white screen. IS there a driver or something I am missing?

I have a mac book thin air, it does not have a usb , I am looking for a &quot;55&quot; monitor to use with this, do you have one compatible with Mac book thin air?

Asked by: rhome
Your MacBook Air should have a Thunderbolt 3 (USB-C) port that can be connected to the Thunderbolt 3 port or USB-C ports on the LG 27 inch UltraFine 5K IPS Monitor with macOS Compatibility, Model # 27MD5KL-B. Regrettably, we do not have any 55&quot; monitors in our Consumer division. YOu can visit our Business Division for Commercial Displays of that size or use our 55&quot; consumer TVs as a monitor...^IFV

My Mac Pro has a DVI output for monitor. What cable would I use? Would this LG monitor still OS compatible with my Mac Pro?

Asked by: Chris T
Ivanf is not correct. There are no DVI to USB Type C adapters &ndash;&nbsp;only USB Type C to DVI. In this case, the Thunderbolt protocol is used to transport the underlying DisplayPort signal over a USB Type C cable. DVI, like HDMI, cannot be adapted to DisplayPort, either (unless the conversion is active), although the inverse is possible (DisplayPort to DVI/HDMI). Even if such a conversion were possible in the case of this monitor, your Mac Pro would not support the resolution of this display. Dual-link DVI supports a maximum resolution of 2560x1600 (~2K), well below the 5K of this display. You will also find that it is nearly impossible to adapt dual-link DVI to anything above 1920x1200 resolution using a DVI to HDMI cable, despite the fact that it IS technically possible to do so with HDMI revision 1.4 and later. Depending upon the model of your Mac Pro, upgrading the video card to one that offers DisplayPort/mini-DP output would be the only viable option to connect to a 4K/5K display; keep in mind that it may not be possible to run a Type C-only display from such a card regardless.

I am buying this monitor to replace a failing 6 year old Apple Thunderbolt monitor. I have VMware Fusion on my Mac to run inspection programs that are only written for windows. Will this monitor work with those windows programs?

Asked by: Trophyfluke
Regrettably, we are not familiar with the specifications for your VMware Fusion. VMware Fusion gives Mac users the power to run Windows on Mac along with hundreds of other operating systems side by side with Mac applications so is should affect what your Mac outputs to the LG 27 inch UltraFine 5K IPS Monitor with macOS Compatibility, Model # 27MD5KL-B. We highly recommend that you contact the manufacturer for advice...^IFV
