What operating system do you have on the PC/Laptop that you have connected to the LG UltraGear 27" IPS LED QHD FreeSync and G-SYNC Compatible Monitor with HDR, Model # 27GN850-B? Screen flickering in Windows 10 is usually caused by a display driver issue or incompatible app. To determine whether a display driver or app is causing the problem, check to see if Task Manager flickers. If Task Manager flickers along with everything else on the screen, a display driver is probably causing the problem. If Task Manager doesn't flicker while the rest of the screen is flickering, an incompatible app is probably causing the problem. The monitor is a Plug and Play monitor so the issue is more likely to be with an application or if the refresh rate isn't optimal, or is too low, flickering, lag, and other issues can occur. You can check the refresh rate on a Windows 10 PC by hitting the Windows key, typing "refresh rate" into the search field, and then clicking on View Advanced Display Info. From there click on Display Adapter Properties For Display 1 (or whichever number display is causing the issue). Click the middle tab, titled Monitor, in the properties window that appears and you'll see an area to set the refresh rate. A video card that isn't properly seated on the motherboard can cause a lot of problems, including a screen flicker. Turn the computer off and open the case. Find the video card and check to see if it's properly connected. If the card is seated on the motherboard properly but the issue persists, a faulty card is likely the issue. Testing this is easy, especially if the problem computer has an onboard GPU that you can plug into. Power down the computer, remove the video card, and connect the monitor cable to the onboard card or a second video card you've replaced the old one with. If the problem persists then the issue isn't the card--it's something else. It doesn't matter if you're using a VGA, HDMI, DVI, or DisplayPort cable to connect your monitor to a computer: If the cable isn't securely connected there are going to be issues. Check the cable at both the computer and monitor ends. If tightening it down or reconnecting it doesn't fix the problem try replacing the cable with a new one. If that doesn't fix the issue it's time to investigate something else...^IFV
Sorry, there was a problem. Please try again later.Make sure you plug into your graphics card and not your motherboard display port. That is what fixed the issue I had with flickering.
