Technical information

1.1 1. Operation

IBM Personal System/2 Displays are analog displays with three to six

externally controlled display modes.

All displays have the following features:

 Tilt or lift tilt swivel stands

 Three to six operating modes (resolution controls)

 Brightness control

 Power-on LED indicator

 Power-on/off pushbutton

 Display self-test with a white screen test pattern

 For color displays, analog video inputs that allow an infinite number

of color choices

 Automatic degaussing

 Very low magnetic field (VLMF) characteristics

 Low electrostatic field (ESF) characteristics

 Very low electric field (VLEF) characteristics

 1.8-m (6-ft) signal cable with 15-pin, D-type connector

 1.8-m (6-ft) detachable power cord.

Additionally, 95xx display models comply with ISO 9241/3 standards to

reduce flicker

Besides the external operator controls, all displays include a cathode ray

tube (CRT) and a card assembly. These are enclosed in the two-part

housing consisting of the bezel, in which the CRT is mounted, and the back

cover, which encases the card tray assembly.

The card tray assembly is made up of an analog card and a video card.

These cards are mounted on an assembly tray which also mounts the signal

cable and ac inlet connector.

The functions of the displays and all of the components within each are

essentially the same, with some differences in the functional

characteristics of the unit -- higher resolutions or larger CRT-screen

sizes, for example.

Each display has various models available that conform to the voltages and

supply requirements found in different countries. Low voltage models are

typically available for the Unites States and Canada in the Northern

Hemisphere; high voltage models are designed for use in the Southern

Hemisphere and Europe, the Middle East, and Africa. Universal voltage

models are designed for use in many countries in both the northern and

southern hemispheres.

Parts lists for these displays include part numbers for each of the models

offered under the display type.
