Dell U2410 miserable colors

Hi,

I bought two U2410 monitors and both of them display miserable colors. I tried all presets except custom one. In most cases the blue color is a domination color, and there is to much backlight on black color. Before U2410 Ive been using 2408WPF, comparing those 2 models, 2408WPF had more vivid colors and almost perfect view angles. Both of my U2410 have also very poor view angles, image is quite good only when im sitting in front of the monitor. Default settings of U2410 are way to bright, im working on brightness set to 5, and contrast set to 50. Longer work with U2410 causes eye strain. Maybe both of my U2410 are damaged?

Could someone help me with the configuration of U2410?
