Dark video

I have a Android box. Xgody R-BOXPRO TV BOX that uses a S912 chip.

Searching through I managed to solve an issue I had with my dark video that wouldn’t allow the brightness slider to work.

However, every film or TV show I fire up I have to increase the brightness slider from 50% to 60% everytime. TV brightness is fine for everything else, just KODI video.

Is there another setting I need to tweak or any way of setting the brightness default higher ?

Thanks
