Let me first ask if you are using onboard graphics or a seperate card? If separate card, is it PCIe? Ver 2? Do you have a diagnostics program ( dxdiags ) built into windows. Should this pass, you may have an out of date driver for your video. If this is not the case, I would think some RAM is on the edge of crapping out.
All the colours on the screen are created by "mixing" the 3 "primary" colours (red, blue, green).
Once the production of "green" ceases, anything that should be "100% green" becomes "100% black",
and every colour that indicates some percentage of "green" becomes a mixture of just RED and BLUE, i.e., various shades of PINK.
First, try the monitor on another computer (desktop or laptop). If the problem persists, it's time to replace the monitor. If the problem vanishes, it's the video-card in your computer that is not generating GREEN, or it is the "data" cable between your monitor and your computer that is not transmitting the GREEN request. So, you can try replacing the data-cable, or try replacing the video-card.
If you have a LCD-screen, not an old-style CRT-screen, it is the data-cable, and its connections, that are not transmitting one of the 3 "primary" colours, e.g., mix red & blue & green to get white,
but mix only two of those colours, and you could get pink,
because the mixing is an "additive" process.
If you mix NONE of the 3 primary colours, you should get BLACK.
If you see GREEN, you're seeing ONE of the primary colours.
What you do is first get into tube lenses and wipe them clean.
Then turn down the colour to black and white.
The simplest way to adjust the three separate colours is to get to the hv splitter box and adjust every screen pot until you get a black and white pic.
Then turn your colour back up and you should see a good result.
