SYSTEM OVERVIEW
1.1 Introduction
This specification describes a low-cost high performance 19" color auto-scan monitor which will operate with
high-end Windows and CAD/CAM applications. This intelligent monitor is microprocessor controlled with a
powerful memory base of pre-programmed screen and input configurations. It also allows users to place their
own settings into memory via external controls. It's setting status is indicated on screen. It is compatible with
various kind of computers and graphics adapters it synchronizes automatically with the signal from 30KHz to
98k Hz horizontal frequency and from 50Hz to 160Hz Vertical scan frequency. When it works on 1024 x 768
non-interlaced/70Hz mode, the refresh rate for flicker-free high quality image will help to reduce eyestrain. A
power management function has been designed to save power consumption and power management is
compliant with VESA & TCO. The monitor is available with two industrial designs: one for ACER and the other
for OEM.
It has the following features:
-With unique design of iScreen
-Auto range power supply
-0.26mm dot pitch CRT.
-User controls: Power switch, Auto Calibrating, Control keys.
-On screen control keys for user:
Enter key : enter sub-menus or select items
Exit key : Enter OSD or back to main menus (auto save), or leave OSD.
Left key : For left adjustment and enter contrast hot-key function.
Right key : For right adjustment and enter brightness hot-key function
-Power on/off indicator
-Power on auto degaussing
-20 seconds auto save function
-Total 20 modes for factory and user settings
