When I boot windows 10, problem has occurred.
That is, monitor brightness has low level.
I contact monitor company, they said we have no problem.
Maybe graphic card has a problem.
Not monitor problem, Not windows setting problem.
When I boot computer, brightness is good in BIOS menu.
But windows 10 is loaded, brightness is so low.
So, I turn monitor off and on, then brightness is recovered.
I do this behavior everytime...
What can I do?
