My first 21-inch CRT


Great monitor for its time -- extremely durable -- has served me well.

Very heavy, bulky, outdated

Product Specifications

The Professional Series displays from Sony provide demanding CAD/CAM, desktop publishing and graphics professionals with a new class of image quality and consistency. A Trinitron CRT, higher scan rates, advanced onscreen digital controls and dual video inputs make the 21-inch GDM-500PS a lot of monitor for the money. Image performance sets this monitor apart from its competitors. The Trinitron CRT has a new design that makes it almost 50% flatter than other aperture grill CRTs for even less distortion. The super fine .26mm aperture grill pitch and anti-reflective coating yield superior images. Sony's Elliptical Correction System improves image accuracy and clarity out to the corners of the 19.8-inch viewing area. The Active Signal Correction circuitry makes quick work of centering and sizing the screen image. The GDM-500PS supports a maximum resolution of 1600x1200, with flicker-free viewing at that high resolution. Digital on-screen controls provide for comprehensive adjustment of screen properties such as pincushion and raster rotation, key and pin balance and moire cancellation, and the color temperature controls ensure color accuracy. An added feature is dual video inputs for 15-pin mini D-sub and 5xBNC connectors. This monitor is designed for graphics professionals who require crisp, clear, consistent images in a multi-featured, graphics monitor. Engineered to take up less room on the desk, the GDM-500PS features a short neck CRT and new compact cabinet design for reduced monitor depth. The detachable tilt base with wide angle swivel lets viewers easily adjust the monitor's position. The GDM-500PS uses Sony's Digital Multiscan Technology to support multiple Mac and PC resolutions, including Windows NT. It is also plug and play compatible for easy setup and operation under Windows 95. To ensure safe and energy-efficient use, the GDM-500PS meets tough TCO '92 emission level standards and power management functions comply with International Energy Star requirements.
