I think there's missing details here. Some have ECO settings or something else. WIthout a make and full model number I can't look into this one.
Also, that 1060 based laptop would be new. Tell the maker that won't answer basic questions like this. I don't want their products either.
I have a laptop, with a Intel HD Graphics 530 and a GTX 1060
the display brightness changes according to the color of the page I load. If I load a white page the display gets brighter, if I load a dark page or software, the display (the screen) gets darker.
I can't find the option to disable that.
Do you have any idea?
