I notice intermittent incomplete white horizontal lines sometimes on my laptop screen. it flashes for a second or so and comes at irregular interval (minutes to hours). Secondly i was gaming alright at low settings with default predator sense (Fan control - auto, gpu - normal) till yesterday when my screen suddenly became purplish and ghosting occured. i immediately switched off my laptop and started again to notice more flashy desktop (like refresh rates visible) on screen. i switched it off again. I connected it to my tv to check if its monitor or gpu. but showed fine on my tv. after playing for sometime on my tv(10 min or so) i again switched it off and restarted. now my laptop screen looks fine. I dont understand why it happened. is there any problem with the lcd screen. or some wiring problem. i keep my laptop with utmost care.

In my opinion, this is a problem on edp cable or display! Have you checked that the problem also remains on an external monitor? Because if the problem manifests itself on the external monitor, this would indicate a problem on the graphics chip!
