How do I change the brightness and contrast settings on my Marshall ML-503 Triple 2RU Rack Mount Monitor?

[DeGarrett]

Adjusting the brightness and contrast on your Marshall ML-503 Triple 2RU Rack Mount Monitor is straightforward. Begin by pressing the MENU button located on the front panel to access the monitor's menu. Navigate to the "PICTURE" menu using the arrow keys and confirm your selection by pressing the MENU button again. Within the "PICTURE" menu, select "Brightness" using the arrow keys and press MENU to confirm. Use the arrow keys to adjust the brightness level; the factory default setting is 50. Increase the value for a brighter display or decrease it for a dimmer image. Press MENU to save your brightness adjustment. Repeat these steps for the "Contrast" option to modify the range between dark and light tones in the picture, also with a default value of 50. Finally, press the MENU button to exit the menu system. For optimal picture settings, consider adjusting the backlight level first; this setting can be found in the "SETTING" menu under "Back light."
