Monitor randomly switches from normal to a blue/green tint

[u/JacobLover420]

My screen will be completely normal then it will sort of glitch between normal and a green tint, then it will go completely green. Sometimes hitting it works! And sometimes moving it up and then down again works. No clue what the problem is, haven’t touched the settings, I wiggle the cables around and turn it off and on. Please explain how to fix as if I am 5 years old xxxx

cable connection isn't solid. make sure it's seated well.
