Just recently, my computer's been getting different colored lines on the bottom 1/3 of the screen of my laptop. I'm using a Dell D530. I've noticed that if I push on the monitor in some places, the lines will go away. It used to be that if I moved the monitor closer or father away, it would disappear, but now it seems as if it's stuck and it won't leave. I'm not sure if it matters, but the colors seem to somewhat reflect what's on my screen (example: the colors change for my background as opposed to a browser being opened.) Any ideas what's up? Thanks!!
