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 521 displays are 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.

Notes:

-The P45 phosphors produce rather bluish images, whereas the P104 phosphors produce more yellowish images.

-A video input terminated to 50 Ohm requires an imaging board with an impedance of 50 Ohm. A video input terminated to 75 Ohm requires an imaging board with an impedance of 75 Ohm.

-The type of CRT phosphors and the video input termination are indicated on the label at the rear of the display.

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

MediCal can be ordered separately.
