I can also access the same thing you can. the point is as so many people have mentioned, once I put the screen brightness to 100% when the laptop is restarted, it goes to 50% automatically until you reset it back to 100%. This is a very common issue with
1809 build....
1809 would also not detect the Nvidia G force card, even after latest updates from Nvidia, and goes to black screen all the time.
Like I was saying if you read my hole message, they have already come out with like 4 or 5 different windows 10 versions now. 1507, 1511, 1803, 1809 and usually the Bios, and software will not
go over 4 builds, even if Bios is updated. Not sure what model your ROG is or what version of windows it came with, but ROG models are usually different, they have completely different main boards in them.
