Proview Technology

Proview Technology’s PT-580 is a 15” thin film transistor (TFT) flat panel LCD monitor. Designed for use with either PC or Mac systems, the monitor is multimedia-ready, complete with a built-in microphone and attachable speakers. Its horizontal frequency of 30-60 kHz, vertical frequency of 60-85 Hz and bandwidth of 85 MHz enable software and Internet-based multimedia applications to appear as sharp as on a CRT monitor and with similar reaction times.


A single-knob on-screen display user control provides easy setting adjustment. A maximum resolution of 1024 x 768 pixels, dot pitch of 0.297 mm, and a maximum video refresh speed of 72 Hz ensure flicker-free image quality. The sharp image is further enhanced through a typical contrast ratio of 200:1 (light to dark).


The PT-580’s 2” thin paneling and 9.5” base allow for a wide selection of viewing angles through both height and tilt adjustment. Schools can purchase these monitors in volume through Proview authorized distributors. Proview Technology, Inc., City of Industry, CA, (877) 377-6843,
