How good are Sony monitors?

Trinitron is Sony's brand name for its line of aperture grille cathode ray tube televisions and computer monitors. Sony invented the design in the 1960s and held the patent until the late 1990s. "Trinitron" is sometimes used as a generic term for CRT monitors equipped with an aperture grille tube. Because of the expiration of Sony's Trinitron patent, manufacturers like Mitsubishi are now free to use the Trinitron design for their own product line without license from Sony. However, they cannot use the Trinitron name; for example, Mitsubishi's are called "Diamondtron." With the emergence of gas plasma and liquid crystal display monitors and televisions, Trinitron and similar brands have been in decline.
