I came home after a trip, and I turned on my computer to see that the whole screen is darker than before. Its not happening repeatedly, one day it just became dark. Brown looks like black. I personally don't like this change, is there anyway to reset this again? I am using a Windows 7 32 bit

It is not only operating system but automatic setting in display. Could you check your computer with different display? If you have notebook, use external display. Hope you have latest video driver. Also look into list of power saving parameters. Regards Milos

If you are using laptop, please make sure it has enough power. Niki Han TechNet Community Support
