LCD Monitors from 6 years ago had about a 4 year life span. Unfortunately your has just ran out of life. Part of the screen going dark is indicative of the screen about to die.
LCDs work by having light strips going around the sites and top. When part of the screen goes dark, it means the light strip has died and the screen is soon to follow. There is nothing you can do to fix it, short of paying more money than it would cost to buy a new one.
Sorry.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
