I'm not sure what just happened but this webpage literally damaged my monitor.

There is now some flickering over the whole screen (it's not my mind, I filmed and checked my mind with another screen)

Given that people recommend pages like this to try fixing stuck bad pixels, makes sense that it could also break them.

I've been having problems with my Mac M1 laptop display (4 years old), and this kicked them back in.

But to be clear: display was already having issues and i have a service appointment to get it replaced
