Just got LG Ergo 32UN880-B monitor to be paired with Macbook pro intel running on Catalina. When I watch Netflix or any video media with subtitles, the screen dims when there is no subtitle on screen, and turns bright again when subtitles appear. I suspect it was the auto brightness setting, but there is no auto brightness setting. I tried turning off the SMART ENERGY SAVING setting, but the problem is still there. Then i turned off LG's DFC (Digital Fine Content) setting, still to no avail. There is no setting for it also on Mac's system preference display setting. I searched in the manual, explored forums after forums, still no answer. Any other people has this problem? Welp....
