Hi tintin,
I think it's due to the electro magnetic fields attracting and repelling dust and particulates in the air around the monitor.
Care should be taken when turning on and off your monitor.Keeping your face away from the front, as dust can be ejected into your eyes and lungs when the screen automatically degausses. I believe this is what happens as I myself got it in the eyes once as I turned the monitor on.
I maybe wrong but it seems that that is whats going on, it could also be due to heat convections around the monitor.
Also just thought about the yellowing thing and wondered if anyone's tried whitening toothpaste ?
Might come out pearly white and smell minty fresh when it all heats up. ;-)
