Since you said it was new, I'll presume it was purchased from an authorized vendor. The best advise would be to return or exchange it. Don't mess with it in any way that can void that warranty.
Bought my first LCD monitor, an AOC 2436Vh. The color varies a great deal from the top to the bottom of the screen. The desktop has a dark blue at the top, but it becomes quite light at the bottom. The task bar is hazy. If I bend my head way down, the haze goes away. If I back up to 3 feet, the effect is much less, but my old eyes can't read the text. The computer is a Lenovo K230,running Vista Home Premium and with just the Intel G33/G31 Chipset. Resolution is 1920/1080.
