Question Green tint on border of the monitor

[Atharva_2001]

Hi there,

I am using the monitor (LG 22mp68vq) monitor for about a year, and recently noticed that it started showing this greenish tint on all the edges of the monitor fading inwards about half an inch.

From front view on bright backgrounds the effect seems to become less noticeable but maybe its because of the background, So i tried seeing it on a complete black screen and the tint is much more visible, also it appears strong if I look at it from top.

My father who kinda know about such stuff a little says it might be due to the moisture, and It is raining a lot these days so the temperature is a bit low than usual.

Would be glad if someone could figure it out for me.

Update after an hour or so the green stuff gone, maybe it's due to the moisture
