Evaluation of the Cornerstone p1750 22-Inch Diagonal Color CRT Monitor for Monoscopic and Stereoscopic Imagery

摘要

Color monitors are more difficult to evaluate and their performance may not compare to monochrome monitors. Color monitors have three electron guns (k, G, and B) to focus and converge. They also have a perforated steel shadow mask that separates the colors on the screen and this adds complexity. Color lines formed on the phosphor screen may not be as narrow as for a monochrome, single electron gun-formed spot. The color monitor's light output may not be as high. The IEC monitor specifications for color monitors reflect this difference, and have lower luminance and stereo extinction ratio requirements than a monochrome monitor. In spite of these limitations, Imagery and Geospatial Analysts at a number of sites may do all their analyses on color monitors.
