Hi and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.
For us to fix this we need to adjust the screen brightness:
Method 1:
Press Windows key + A to open the action center then you will see a slider bar for the brightness to adjust it.
Method 2:
Go to Settings> System> Display - then adjust the brightness from there
Let me know how does it go and I hope that helps.
