Say wha? You bumped the LCD SCREEN up to 100Hz and it changed something!@?? I have always been under the impression ALL LCD screens were locked at 60Hz. Even changing the value wouldn't modify anything visually for the end user. As it is mine only gives me options for 60 or 70Hz :/ How did you get 100Hz set for the LCD? I have noticed some slower response times than other users have - but I have no idea how refresh rate could fix this? Any more info would be appreciated. Perhaps you just think 100Hz makes a difference.... I know its happened to me before with other things!
