What People Are Saying

Rated 3 out of 5 by from Good but.. Monitor is beautiful. But I get a lot of black screens for a second or so. Playing on Xbox and I’m not sure how to fix (if you can) this. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Excellent monitor for gaming and everyday use! I have been using this monitor for less than a week now, had absolutely no issues. I have this hooked up to a early 2015 MacBook Pro retina through the display port and it works flawlessly. I also have my Xbox one X hooked up, gameplay is very smooth, HDR games look stunning, FreeSync works as intended. I initially had some trouble updating the software on this monitor through the OnScreen Control, it wouldn’t recognize the USB-C cable with adapter (original accessories) on the mac. To solve this issue I just had to update my OnScreen Control to version 3.06 (downloaded from LG’s support page) and restart my computer, it immediately recognized that the monitor was plugged in and allowed me to update my monitors software to the latest version (3.14, 1.34). Overall I’m happy with my purchase.

Rated 5 out of 5 by from Best price for intense tech I wanted a 5K monitor but quickly found limited options in the 32" range. As a video editor I need accuracy, incredible quality, and scalability. This impressive monster of a monitor is advanced enough that even if I need 5K later, it's advanced enough to be on my A team for years. There are so many features for future usage that I have no fear that it will grow with me. And, the gaming features are there when I need them down the road.
