Rated 5 out of 5 by from Great Monitor Screen is perfect size. No dead pixels. Black screens look perfect. No whitening on corners or edges. No pixelation or tearing so far. I have got it up to 120 FPS so far in games. I love it.

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.

Hi I was just curious I have this monitor and at Best Buy it says G-sync and freesync but the monitor itself only has a sticker for Nvidia G-sync so my question is with my AMD graphics card can I set up freesync

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.
