Laptop problem: White horizontal flash at the bottom of laptop screen?

Hey near,

Looks like your LCD screen is having trouble coordinating its outcome time uniformly all for all the pixels. I'd say it's time to replace the screen. If you've AN external monitor, hook it up and cheque the yield just to Be positive its not the video card (ne`er heard of a video card causing this though). Prospect your laptop's still under warranty.

Response Time
~~~~~~~~~~~
Within order to achieve the color on a pixel in an LCD panel, a current is applied to the crystals at that pixel to change the convey of the crystals. Response times consult the magnitude of time it takes for the crystals in the sheet to move from an on to off state. A improving response time refers to the magnitude of time it takes to turn on the crystals and the falling time is the amount of time it takes for the crystals to move from an on to off state. Swelling times tend to be very fast on LCDs, but the falling time tends to be much slower. This tends to cause a slight blurring effect on bright moving images on black backgrounds. The humiliate the response time, the less of a blurring outcome location module be on the eyeshade. Most response times now consult a gray to gray rating that generates a lower time than the traditional full on off say riposte times.
