While playing games, every time i enter a dark area, the brightness changes by becoming even darker. It becomes brighter once i enter a more bright area. I think it's my LG monitor doing this because this happens in all games. However the auto power saving mode turns out to be off already. I don't have a laptop btw.

I forgot what model it is, but it is an IPS screen. 1920x1080 resolution.
Reader function is off. Func menu says: SMART ENERGY SAVING. That's turned off. 5 picture modes; Custom, Text, Photo, Movie and Game. Last it says Color weakness, which is turned off.
