I see two very fine horizontal lines across my display. KDS AND SONY both say its normal for All models under the KDS Avitron brand are based on Trinitron CRTs manufactured by Sony. This type of CRT
uses aperture grille technology, rather than the standard shadow-mask technology, to distribute and focus
electron beams to the screen.
Shadow mask tubes have a thin foil of metal, perforated by a grid of small holes, attached to the inside of the screen. Aperture grille tubes instead use an array of
vertically arranged wires.
Depending on the size of the tube, these wire arrays require 1, 2, or 3 very fine suspension wires across them to stabilize the wires in the aperture grille. Without
these, the display would be very sensitive to any shock or vibration and result in visible shimmering or rippling. (In fact, even with these stabilizing wires, you can
usually see this shimmering if you whack a Trinitron monitor.) The lines you see are the shadows cast by these fine wires.
The number of wires depends on the size of the screen. Below 15" there is usually a single wire; between 15" and 21" there are usually 2 wires;
above 21" there may be 3 wires.
Only you can decide if this effect is serious enough to avoid the use of a Trinitron based monitor. Some people never get used to the fine
lines. Most users really like the generally high quality and rich depth of color that Trinitron-based displays offer. They become accustomed to the lines, and they
cease to be a concern.
THIS kinda sucks, but its not that bad
anybody having problems with the lines?
