1. INTRODUCTION

The BARCO MGD 221 is a high resolution, greyscale portrait display.

Its outstanding visual performance, combining a 2 MegaPixel

resolution with a high brightness, makes it ideal for medical imaging

and many other medical and scientific applications.

The MGD 221 is compatible with any AC power system worldwide

and automatically synchronizes to a wide range of sync frequencies.

Its high-speed video amplifier supports pixel clocks up to 250 MHz.

The internal memory system can contain the adjustments for 8

different scanning formats, the so-called scanning modes. Each

scanning format is characterized by its sync signals. The display’s

internal micro controller continuously samples the connected sync

signals and compares them to the scanning modes already stored in

the memory. If the connected signal has already been stored, the

micro controller adapts the image to the corresponding adjustment

values in the memory, and further adjustments are unnecessary.

Image conformity and consistency are the keywords. In our factory,

the MGD 221 displays are perfectly adjusted and calibrated before

they are shipped to the customer. Internal circuits, like the TrueGrey®

and Automatic White Stability (AWS) systems, ensure display

consistency over time.

Conformity with the original image quality is guaranteed by the

automatic calibration, which can be done by means of an optical

sensor, connected to the Sensor connector on the display. The

sensor is not supplied with the display.

The conformity calibration, as well as the complete adjustment of the

display, can be performed by means of the remote, user-friendly

MediCal® software package. MediCal, is especially developed to

adjust and check BARCO’s medical displays.
