Incidentally, I have a dell inspiron with a TFT display that for the first time is not giving me headaches (installed linux on it). Not sure what is different on it since iv'e tried several other similar displays. I thought my eyes are maybe too sensitive since they are light green when maybe brown eyes have more shade to them.
I envy people with better eyes!
Also iv'e noticed that amoled phone screens don't give me any headaches while TFT phone screens do. Amoled uses phosphors similar to CRT, so they are compatible technology other than the fact that CRTs have a gun that lights up the Phosphors whereas Amoled lights up the panel more directly.
Weird world.
