Was just given a rather nice ViewSonic A90f+ monitor which seems to work ok, except for the fact that the color is way off. It seems like it's unable to show any green so all colors which use green are way off.
I know this because yellow isn't supposed to look red and Cyan shouldn't be solid blue. Overall it has a purplish hue. I checked the pins and all seems fine.
Info here -->

Anyway, anyone know what I can do about this?

Following the observations by and , here are focused, practical checks and brief explanations to help pinpoint why a display shows no green without repeating earlier steps.

Begin by isolating the problem source. Use the monitor OSD or any built-in self-test / color pattern: the OSD is generated by the monitor itself, so if its menus look normal (white/neutral), the monitor's color engine is likely OK; if the OSD is also missing green, the fault is inside the monitor. Look at the screen during BIOS or the PC boot splash (before drivers load): a persistent tint at that stage points to hardware, not software. Test the monitor on a different computer and test the computer with a known-good monitor to separate monitor vs source.

For analog connections note that each color channel has its own path (VGA DE-15 maps green to a dedicated pin). A failing contact, broken conductor, or bad adapter will remove a single channel while leaving others intact. Switching to another cable type or a different video output on the PC helps isolate cable/connector vs GPU. If diagnostics indicate an internal CRT fault, try degaussing first but do not open the case—CRTs have dangerous high voltage. When internal electronics are implicated, professional repair or replacement is the safest option.

I've tried two monitors on my system and the display is showing a pink hue and no green. I updated driver. and checked pins all seem correct. Help please.

My issue was a bad cable.
Being that you have two monitors that act this way makes me think the connector on the card is bad. Either check the card to see if one of the metal pins on the connector aren't bent or get another graphics card.
