Alright, i have a HP laptop (DV9000) and i pressed Fn + F4, or the external monitor switch. Now everything is completely messed, Most things have turned black, the windows sidebar is now completely opaque, the wallpaper is now green with distorted hues, i can hardly see some things anymore. I've tried restarting, tried Google, tried going through display settings, tried everything. If anyone knows anything...please let me know, this is extreamly annoying, I just want to get my display back...
