Use the monitor then only blue and violet color show not show all colors

Question edited for clarity, and funky comma use and spaces.
Question moved to model category.

What happens when you change the monitors to the different ports? Does the violet monitor stay violet when it is plugged into the other video port?
I am guessing that the monitor that is violet is using a VGA connection

The most common cause of a monitor displaying a pink or violet color cast is that one of the RGB conductors in the VGA cable is broken, or the plugs are not firmly seated in the sockets, leading to one color not firing on the monitor. Try a different cable. Try plugging it in with DVI instead.

All branded car stereo system color cods are same. FR-speaker:brown,brown with black. FL-speaker:white,white with black. RR-speaker:violet,violet with black. RL-speaker:green, green with black. Yellow:battery. Red:key main ( acc). Black:ground. Blue and blue with white: amp remote or power antenna. Thanks.

You might have "color filter" settings. Turn the digital filters off. Here is what manual at p72 says. "You can take pictures using digital filters. The filters consist of color filters such as red, blue and green, a soft filter that produces a fuzzy effect. Color filters Eight colors, black-and-white, sepia, red, pink, violet, blue, green and yellow, are provided for the color filters. When you select a color filter in the Digital Filter mode, the display on the LCD monitor is filtered with the selected color, and the pictures are taken in that color."
