A lot of adjustments can also be done on the monitor itself, by means of an extensive on-screen menu system, accessible from the rear panel controls.

Power saving system

The MGD 221 is equipped with a power saving system.

When left idle for a certain time, the computer, connected to the display, will power down the display in several steps. The power saving system can be switched on or off during the installation or adjustment of the display.

This system requires a computer imaging board that supports power saving management.

1.2 Versions and options

The MGD 221 comes in 2 different versions: With an anti-reflective panel in front of the picture tube, and without panel (No Panel version).

In both cases, the phosphor is a B4-L8 type.

The type of CRT phosphor and the presence of the coating are indicated on the label at the rear of the display.

The video input is terminated to 75 Ohm.

Important: It is absolutely necessary that the impedances of imaging board and display are the same. If not, the image quality will be inferior.

The MGD 221 can be delivered with the following options: Southern Hemisphere Compensation and Ambient Light Compensation (ALC).

The MediCal software and the X-Rite DTP92 sensor are not delivered with the display.

MediCal can be ordered separately.
