What's causing the issue with your monitor?
You're experiencing recurring issues with your LG-UltraGear 27GN800P-B display. After replacing stuck pixels, scan lines reappeared, suggesting a potential problem with the LCD controller or LG's freesync implementation. The issue seems to occur specifically when playing Elden Ring in full-screen with freesync enabled, while it works fine in other games like Bayonetta. You're curious whether the monitor is failing or if LG's freesync is problematic. A video documenting this behavior is available here: https://vimeo.com/828155382?share=copy
The main concern would be during display mode transitions (like switching to fullscreen or adjusting resolution). It might point to a driver, cable, or GPU problem. I’d make sure drivers are current, look up any reported issues in forums, and consider replacing your video cable.
