I have an LG 42LK450 which I use only for gaming. At the corners and at the very bottom it appears the back light shows through. If I shift slightly the angle I am looking at the screen and it goes away. Meaning it will always be black when directly looking at the screen and there will be a slight discoloration or brighter area where I am not looking directly at it. If I sit further than 4 feet away it goes away, also when I have it on in complete darkness with the LG screen saver on it goes away. I also have an 32LD350 which has similar traits. Forgive my ignorance on this, I was just wondering if this is a normal trait of LCD screens?
