Here’s what my LG C1 panel looks like after three years of heavy use (8+ hrs/day), used exclusively as a monitor. Primary tasks include gaming, watching YouTube in a window, and full-screen music production and video editing.

I’ve disabled the burn-in protection in the service menu (TPC & GSR) because they dim the screen too much and make text difficult to read. The only preventive measures I take are autohiding the taskbar and setting the wallpaper to randomly cycle every 30 minutes. I consider burn-in a non issue.
