What people are saying

Rated 4 out of 5 by from Very good colors brightness and picture Product has a very good refresh rate, great color reproduction and working well for gaming, however my model came with a defect that made black pixels sometimes be white, also a down side is the fact that it doesn’t true my support hdr, and windows will refuse to display windows store games in hdr because of it

Rated 5 out of 5 by from Great value This monitor is a great value. My games look great and crisp in 2K at 140+ Hz with V-Sync and a Nvidia Geforce RTX 2070 SUPER. I noticed no dead pixels. My only issue is that I'm not sure that I can notice when HDR is active, but regardless, it slows down frame rates.

Rated 5 out of 5 by from Great Monitor I bought this 2 weeks ago when I got the new Xbox series x and the monitor performs beautifully. Games and movies haven’t looked any better

Hi, can this monitor have its resolution changed down to 1080p? Until I get a better GPU to run 1440p more effectively. Or will it automatically adjust? I have an asus 24inch 1080p @60mhz monitor currently, screen split/ tear is awful.

What is the difference between this model and the LG27GL850?

Asked by: Tam122
The L is 2019 the N is 2020. This is also $50 dollars cheaper because it does not have the USB hub that the 2019 model had.

Hello LG, Will is there be a release for the EU/Netherlands ?

Asked by: JoeyP010

What do I do if the monitor has no picture? When I plug the power cord, the LED light is red for a few seconds and turns off, and when I press the button nothing happens.
