I'm interested as to how this happened:

Perfectly formed circles, after the monitor got wet (ok, my cat
"scented" it, which I assume is salty water) - why the circles? I can't
believe the "water" physically spread that evenly. And I'm unaware of
any connection in an LCD monitor activating a circle - wouldn't I short
out a horizontal band or something?
Dig out your polarized sunglasses and see if you learn anything.
Might have damaged the front polarizer.

I don't have sunglasses.

Is the polarizer replaceable? I can find a few people selling the film to
replace it, but I'm not sure how easy it is or if it's worth the bother.
A couple of Youtube videos on changing one make it look like a work of
art.

It still seems strange I'm getting very accurate circles. Although
they're gradually expanding, and not always exactly circular. One now
looks like a pacman shape, and another has little scrape marks next to it.


I suspect it is dffusion outwards from a small drop of solution. As to
what is diffusing, I have no idea. Presumably some chemical constituent
of the urine I suppose.
