Evaluation of the Mitsubishi 2040u 4 x 3 Aspect Ratio, 22-Inch Diagonal Color Monitor

Abstract

NIDL certifies the Mitsubishi 2040u color monitor as being suitable for IEC workstations. Its performance significantly exceeds the 2020u color CRT monitor it replaces. Importantly, it exceeds the IEC specification for contrast modulation by 100% in the monoscopic mode. Accordingly, NIDL rates this color monitor as "A" in the monoscopic mode. We rate it "C" in the stereoscopic mode for the Image Analyst and Cartographer applications, principally because its refresh rate of 55 Hz per eye does not meet the 60 Hz per eye IEC specification; otherwise it would have been a "B". The Sun Creator 3D driver card in the IEC workstation is limited to about 55 Hz per eye so stereo performance may be acceptable. With the NuVision 21 inch shutter panel and passive eyewear similar to that used by the IEC workstation, we measure an extinction ratio of about 10.4 to 1. With Stereographic wireless CrystalEyes, the stereo extinction ratio at screen center measures 17.5 to 1 and exceeds the IEC specification determined with CrystalEyes of 15 to 1 for a color monitor.
