Evaluation of the Hitachi CM814U 4 x 3 Aspect Ratio, 21-Inch Diagonal Color CRT Monitor

Abstract

The Hitachi CM814U 21 inch color monitor (20' viewable area, selling price $1200) has very good image quality and features that make it an excellent candidate display device for NIMA Imagery Exploitation Capability workstations. Based on our evaluation, NIDL certifies the Hitachi CM814U color monitor as being suitable for IEC workstations. NlDL rates this color monitor as a "B" for the Image Analyst and Cartographer applications. The "B" ratings, rather than "A", result from a slightly high halation and non-linearity values, and from a somewhat low stereo extinction ratio. In a light ambient, the monitor is calculated to achieve 158:1 dynamic range with 3 fc illumination, and 62:1 with 10 fc illumination falling onto the screen.
