Two lines when a video is in FULLSCREEN?

[Daylife]

Hey guys ive noticed that on my G75 when i put a YouTube video in fullscreen there are two lines that show up.....Screen tearing pretty much, also on netflix when i put the video full screen the same thing happens.

Is there any way of taking that off?

Set the vsync in the nVidia control center to either on or adaptive, and it should take care of that.

what is the difference between ON or Adaptive?
