We lost most colors except green and purple

probably the color setting of the monitor has been changed.
on the monitor panel press the menu button and go to the color option.
see if increasing or decreasing the RED GREEN and BLUE color options sets back the monitor to normal.
usually some monitors have a reset option also, by selecting it everything will get back to normal.

Get a new cable for the monitor.

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

your monitor is either going bad or your display setting are messed up.use the buttons on the front and mess with color option if that don't work then you need a new monitor

Sounds like a piture tube or internal video driver in your monitor. You probably lost the green channel. If the monitor is dated I would replace it.

Sorry time for a new monitor you might open it up and look at the capacitors and see if any need to be replaced the bad ones will be domed on top normal is completely flat

The monitor convergance adjustment is out . Is it a LCD or CRT

Replace D805 (?) Thermistor for permanent fix, manually
degauss with coil is temporary........T.

So your sure when you go into the monitor settings, and color, it is set to like 9300k or something? It probably isn't the monitor, because the video games you said display just fine.
