Evaluation of the IBM T221 16 x 10 Aspect Ratio, 22.2-Inch Diagonal 3840 x 2400 Pixel LCD Color Monitor

摘要

NIDL evaluated a 22-inch diagonal 0.12 mm pixel pitch IBM 3840 x 2400 pixels (9-megapixels) color digitally-addressed LCD monitor Model T221 purchased for delivery to NIMA. IBM has recently reduced the purchase price to $8,399. We find that images and Briggs patterns at 2X (1920 x 1200 pixels) look excellent. The monitor exceeds the NIMA IEC Working Group specifications for monoscopic mode color applications. Accordingly NIDL gives it an A' rating and thereby certifies the IBM 9-megapixel monitor for color monoscopic IEC workstations. LCDs generally cannot refresh fast enough to do stereo at the 120 Hz vertical refresh rate needed for StereoGraphics ZScreen or CrystalEyes based stereo. We found that the ability to roam quickly is a function of the computer the display graphics card the image manipulation software and the display itself For the T221 using a low-end version of Remote View the smoothest roam of three graphics cards tested was observed using a Radeon 8500 single-DVI digital display graphics card at 1920 x 1200 pixels at 41Hz. We achieved 100 to 300 pixels per second.
