Evaluation of the Orwin Associates DEX 2102L, 4 x 3 Aspect Ratio, 21-Inch Diagonal Monochrome Monitor (a.k.a DEX 2101L in NIDL Report)
Abstract
The Orwin Associates DEX 2102L (NIDL had previously misstated the model number in its report as the DEX 2101L monitor) Monochrome CRT Monitor is an excellent 1600 x 1280 pixel, 21 inch monochrome gray scale monitor. The monitor easily passes all the IEC monochrome monitor specifications for both monoscopic and stereo viewing. We have separated the monoscopic from the stereoscopic viewing for grading, but both modes receive an "A" for performance for the Image Analyst and Cartographer applications. This COTS monitor is an excellent display for NIMA Imagery Exploitation Workstations. Accordingly, NIDL certifies the Orwin Associates DEX 21 02L Monochrome CRT Monitor as being suitable for IEC workstations requiring a monochrome monitor. The monitor passes all stereo specifications with a Nuvision panel and its associated passive glasses, or with StereoGraphics wired active glasses. We calculated the dynamic range for various amounts of light falling on the face of the tube for monoscopic operation based on our measurements of reflectivity. Thus, we would expect the Orwin DEX 2102L monitor to have a dynamic range of 398:1 with 3 fc, 158:1 for 10 fc, and 117:1 for 14 fc falling on the screen. The amount of light falling on the screen can be minimized by using a shield to block strong overhead light to thereby increase the contrast ratio.
