I have an acer AL1717 LCD monitor and for some reason when its hooked to my desktop pc and i visit darker pages such as Gamerenders there is a flicker in the lower half of the screen, i have tried all refresh rates, all settings in the monitor menu and still nothing, i cant get rid of this flicker, when i hook it up to my new laptop there is still a slight flicker its not as major but still a slight one. Anyone have any ideas on whats going on?
