These two wires re-inforce the shadow-mask ( not the screen :). Without them some deformations occurs and it become impossible to obtain a correct uniform color Red or Green or Blue because when the alignment of the mask is wrong, the beam which is intended for one color can reach the others. http://home.att.net/~RTRUSCIO/COLORTV.htm Aperture grills have one significant problem and this is what causes the horizontal lines you see. To maintain equal spacing between the vertical wires, the aperture grill has two (one on displays 14 inches or smaller) horizontal damper wires, which hold the vertical wires in place. These wires cast a faint shadow on the phosphor layer that is not normally noticeable, but when you have an image or application with a light background displayed on your monitor, you can see them. -- Pierre Jarillon - http://pjarillon.free.fr/ Vice-pr�sident de l'ABUL : http://abul.org/
