Thin black line on monitor What is the thin black horizontal line on my monitor? The thin black horizontal line visible about two-thirds of the way down some 17" and larger CRT displays is a restraining wire characteristic of some Trinitron screens. Most PC monitors use "shadow mask" grills with tri-dots through which the colored phosphors emit their light. (This is where "dot pitch" comes from: a measure of the proximity of these dots.) Trinitron monitors use a vertical wire grill instead. The proximity of the wires to each other is the "strip pitch". This technology produces a conical screen shape, which appears flatter to the eye than does the spherical shape typical of shadow mask monitors. The cost of this screen flatness is, however, the visible restraint wire. In practice, it is usually only noticeable against a white background. The KDS monitors that we sell use Trinitron tubes, and thus have the thin black line. |
