I absolutley hate this feature about my laptop, and I think Windows 8 is behind it. Anyways, when I am plugged in, my colour brightness is perfect on my laptop. But when I unplug my laptop, my colour brightness goes to hell. Mostly white though, when I go to facebook, the colour white makes reading everything unreadable due to the massive amount blare. I feel like I am staring at the sun. Please help! I have windows 8.1, and ASUS laptop.
