I had a simulator issue when trying to figure out why 1 of the 3 monitors (all this model) was not as clear and crisp as the others. The more I tried to fix the worse the issue became, hence the black/blank screen issue... What solved all problems is Below. On the monitor Itself using the button below the Lg logo in the middle. I went to the menu settings and clicked on the restore to factory or default settings. Once I did that and it restarted it came up with a screen saying that the monitor was not being used in the correct resolution and MHz configuration. It gave the specs which I can’t remember right now.then it tells you to go to your computer to adjust. When doing the display settings in windows it didn’t have the option for that particular resolution the monitor was calling for. So I had to go into the advanced Display setting. That’s when I realized The computer was trying to run it in 59mhz and not 60mhz that the monitor required. So in the advanced drop down list I was able to choose the correct resolution and MHz combination the monitor wanted. Once I did that it fixed the screen blanking out issues and became perfectly crisp and clear like the rest. At that point I used the lg screen splitting software to adjust the picture to fine tune the contrast and brightness to my liking. (Lg doesn’t send the software with the monitor anymore I just know about it from when I bought the 29” model a few years ago. Takes a min to find but once you do and download it, it’s amazing if you want to split your screens and Unlock the true potential of these monitors. The monitors are great by themselves but that software is what really makes them great and that’s why I now have 6 of them!
Sorry, there was a problem. Please try again later.I've had a similar problem with my LG 34" same resolution different model. The problem ended up being my radeon graphics driver. It was solved by downloading the latest driver from AMD and just before the install use the option below the button to install to restore factory defaults. This removes the old driver, restarts your computer, and then installs the latest version. Since doing that it works perfectly.
Sorry, there was a problem. Please try again later.I had the same issue as of today, January 18th, 2023. I was using a USB-C dock which provided HDMI. After changing cables and monitor frequency etc, I had no success. I bought a USB-C to HDMI cable and all is well, and it now works as intended.
