Evaluation of the Viewsonic P817 4 x 3 Aspect Ratio, 21-Inch Diagonal Color CRT Monitor
Abstract
The Viewsonic P817 21 inch monitor (20" viewable area; the selling price is $1600) is a color monitor with image quality and features that make it an excellent candidate display device for NIMA Imagery Exploitation Capability workstations. Based on results of our evaluation, NIDL certifies the Viewsonic P817 color monitor as being suitable for IEC workstations. NIDL rates this color monitor as a "B" (meets IEC requirements) for the Image Analyst and Cartographer applications. The "B" ratings, rather than "A", results from a slightly high halation value, and from a somewhat low, but typical of color monitors, stereo extinction ratio. In a light ambient, the monitor is calculated to achieve 158:1 dynamic range with 3 fc illumination, and 60:1 with 10 fc illumination falling onto the screen. NIDL evaluated the Sun/Sony 24 inch color monitor, gave it an "A" for its performance, and recommended its use for imagery analysts. We based this recommendation on its measured performance, analysts' preference for the 24 inch size with its greater area, and on its reliability. The Viewsonic P817 monitor is a very good color monitor, but the 24 inch Sony performs better in a number of areas but at a somewhat higher price.
