I have a Mitsubishi diamond plus 93SB, which came with my MESH. But there are 2 faint lines exactly where when playing a widescreen DVD . was this caused by me watching a DVD when i first purchased the PC or just because it is flatscreen.
and they're essential - they prevent the very fine wires that form the aperture grille from vibrating and ruining the display quality. What you can see are in fact the shadows cast by the damper wires. Some people (I'm one of them) find these shadow lines irritating, others seem able to ignore them after a time.
There's nothing you can do about them, and they're perfectly normal with this type of display.A couple of years ago this question used to crop up very often, but I can't remember having seen it for a while.
