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.
