does anyone else notice a vertical line when the montior is turned off for a long time and powering on? i notice it if the lcd is warming up....if the lcd is already warmed up and i turn it off for like 5-10 minutes and turn it back on i dont see it. it only appears when its been off for hours. im not sure if its the video card's fault or the lcd....it goes away in a minute or 2 by opening a window in front of the line...but i noticed as time goes by the occurance is much more frequent in the lcd. i dont want to go thru the hassle of sending it back and gettin a refrub but im past the 21 day gaurantee...i f**** hate dell and their robotic replies thru email and outsourced reps
