About viewing modes

The MDNC-3421 can be used in two viewing modes:

• Diagnostic: This mode provides the full calibrated luminance and is intended for using the display for diagnostic purposes.

• Text: In this mode, the luminance is reduced to approximately half of the luminance. This is intended for using the display with office applications such as word processing.

  Please note that text mode is not persistent, once powered off, the unit will restart in diagnostic mode.

Tip: To quickly switch the viewing mode without having to enter the OSD menu, touch the up and down key at the same time during normal operation.

Note: The diagnostic mode should always be selected when the MDNC-3421 is intended to be used in a diagnostic environment.

To select a viewing mode:

1. Bring up the OSD main menu.
2. Navigate to the Configuration > Calibration menu.
3. Enter the Viewing Mode submenu.
4. Select Diagnostic/Text as desired and confirm.
