Is there a way to stop my LG 55" C7 4K Ultra HD OLED from dimming the screen when displaying Web content from my pc? I'm using it as a monitor and just want it to stay at a constant brightness the same as a normal monitor. Currently it dims if left on the same image for a few minutes. Also dims when scrolling down a YouTube page and brightens when you scroll to the top. I've disabled smart dimming but it still does it.
