You sir might be correct, but have you considered this?
*) I didn't see the lines at first either, noone at my office saw them under fluoroscent lights.
*) I only managed to see them at home in a dim environment, and after they become visible you will see them all the time. I then took it to work today and asked coworkers whether they saw the lines when I pointed out where to look and then people DID see them! These are graphics artists, and THEY DIDN'T SEE THEM AT FIRST EITHER, but after a more thorough examination they DID see them.
*) People who can see the lines, to my knowledge, has not seen a SINGLE SCREEN WITHOUT THEM!
*) People who can't see the lines, to my knowledge, has not seen them on a SINGLE SCREEN!
I honestly think it is just a matter of right viewing distance, lighting and proper image on the screen. If you look at the screen from far or under a lamp or look at a very colorful image you won't see them.
