I just got a new computer with a samsung 950p 19" monitor.. I've had the system for about 3 weeks now, and only now I just started to notice in the corners of the monitor there are some curved lines which bend outwards from the center of the computer.. they are only visible in the corners when there is a pure colour displayed on my monitor.. like a purely blue background or something like when booting up into win XP. Otherwise (like now) I cant notice the lines at all. Can't see them in games either. So the only time they are visible at all is when there is a pure colour on the screen and that is pretty rare.. but nevertheless I wanted to ask: Is this a common trait of monitors, or is mine defective? And if it is defective, do you think I should bother returning it for a new one? (I'm still on a 30 day waranty)..
