What People Are Saying

Rated 5 out of 5 by from Outstanding image quality and connectivity An ideal combination of features for a great price: - Spectacular 4K HDR image (watching videos holds up even when compared side to side with my 65" OLED B6) - Great for coding environment, really sharp fonts - Excellent connectivity thanks to USB-C, so i can even charge my Dell XPS laptop with a single cable (provided) - Fast responsive refresh for gaming - HDMI/Displayport/USB-C Cable included (that was a great bonus that didn't realize)

Rated 4 out of 5 by from Great monitor, but macbook power issue Great monitor in all aspects but one ... if you use the USB-C to power your Macbook and then put the monitor into standby then it no longer powers the Macbook. Extremely annoying to open the Macbook to find the battery is run down ... come on this is a common sense fix surely?! The USB-C power and connectivity was one of the main reasons for my purchase to reduce 'lead clutter' at my desk.

Rated 4 out of 5 by from Excellent... after a huge disappointment. Depending on the results of the LG 'monitor lottery' you'll either be over the moon with your LG 27UK850 or frustrated and disappointed. I was sent four faulty screens before receiving two that were good enough to keep. One arrived from the factory with a scratched anti-reflective screen coating, another arrived with a stuck pixel, and the next two suffered from completely unacceptable and display ruining yellow light bleed (not IPS glow) which was financially costly and time consuming. The first two had no display calibration paperwork with them, the second pair did have calibration paperwork, but one of them was soggy and wet whilst inside the sealed box (seriously)! So it appears that LG have awful quality control in place. However, the last two monitors I was sent were far better. In fact one was excellent with almost zero light bleed and the other had only minor light bleed. Both displays provide a beautiful and colour accurate image that boasts a sharpness that looks almost as good as the MacBook Pro screen they are sat alongside. And because they provide USB-C connectivity they power the MacBook Pro (2018 15") and charge it whilst connected using the supplied USB-C cable. They also come fitted with 2 x USB 3.0 inputs which, so far, work perfectly with my external USB 3.0 to Digital Optical sound card. I'm confident the included HDMI inputs work well too. The monitor's built in speakers are ok, though the MacBook Pro speakers are noticeably better. The black bezels could be a little thinner and the monitor is a little plasticky, but the included stand is nice looking and supportive. The main issue with the stand is it doesn't allow the screen to twist left and right (it rises/lowers and tilts forward/backward) and in my case one of my stands was not straight (it leans constantly back by a few degrees). But I have my two monitors attached to a third party display bracket (Vesa 100), so the flawed stand is not a big problem for me. The pain of having to receive and test four faulty monitors before finally receiving two good ones was pretty awful however, but if you're willing to enter the LG monitor lottery you may be luckier than I was. When working as they should they do produce a wonderful picture that's sharp and focused with accurate colour reproduction that's good enough for my needs as a creative designer. I would recommend it in the hope other people don't get sent duds like I was.

Rated 3 out of 5 by from Looks nice..but buggy. I purchased this monitor to use with the 2018 Macbook Pro 15" via USB-C. I've had this monitor for about 3 months now and there are 2 very annoying problems, although I am 100% sure if the fault is the macbook or the monitor. 1. When plugging in the USB-C cable, the USB-hub on the screen works, but my screen does not get extended, it's just blank saying no signal. I have to unplug and plug the cable in multiple times until it eventually works. 2. I keep getting a message on the screen that it will power off if there is no action. Surely the screen should see that the pixels on the screen are changing and not to switch it off? I think this is a bug in the screen firmware.
