Displayed colours way off

[filiboss123]

Hello there;
An issue has come up in my desktop. I was working in eclipse (java programming work for university) when, suddenly, the image started to get pretty messed up. It started to have some sort of ghosting (text was not well defined at all) and, in addition to this, the contrast and colour accuracy just went to hell.
I have been trying to fix this for a long time now and I do not know what else to do. I have checked cables, monitor, however, I do not think it is a GPU derived problem has I tried to run Overwatch and everything became normal again, even the colour, despite this as soon as I left the game it became worse once again. I have also tried to reinstall windows with no results. The screen ghosting has disappeared, however, the colours are still not right (the black seems grey, and colours have very low contrast) and I do not understand how I might correct that.

Can you help me, please?
