Resolution:
A method to increase perceived brightness for MM50 and MM70 at retail outlets should follow the procedure listed below:
NOTE: Not all of these steps (in roman numerals) may not be necessary. Perform all sub-steps under each step and then re-evaluate the quality of the image. Stop once a satisfactory quality is achieved.
I. Physical connections:
1) Turn off the computer and the monitor.
2) Unplug the cable from where it plugs into the system unit. Examine the pins at the end of the connector. Some pins may be missing, however, none should be bent. If any are bent use a set of needle-nose pliers, tweezers, ball point pin, or some implement to bend the pin so that it is straight.
3) Re-plug the cable back into the computer, and tighten the thumb screws.
4) Examine the quality of the picture after the computer is up and running. If the brightness is not satisfactory precede to step II.
II. Standard monitor settings (contrast):
1) While the computer is running do the following:
2) Press the MENU button one time. This will bring up the "Main Menu" and CONTRAST will be selected by default. (Note: if more than 3 seconds elapses without a button being depressed, the menu item will go away.)
3) Press the SELECT button.
4) Increase the Contrast Ratio to 100% by pressing the plus button (+).
5) Examine the quality of the picture. If the brightness is not satisfactory precede to step III.
III. Standard monitor settings (brightness):
1) While the computer is running do the following:
2) Press the MENU button one time. This will bring up the "Main Menu".
3) Press the PLUS (+) button one time. This will select BRIGHTNESS.
4) Press the SELECT button one time. This will allow you to modify the settings.
5) Increase (or decrease) the brightness using the Plus (+) or Minus (-) button so that the value displayed is no more or no less than 50%.
6) Examine the quality of the picture. If the brightness is not satisfactory precede to step IV.
IV. Additional monitor settings (color temperature):
1) While the computer is running do the following:
2) Press the MENU button two times. This will bring up the "Color Control Menu".
3) Next, press the Plus (+) button so that the "PRESET COLOR" symbol is flashing.
4) Press the SELECT button.
5) Press the Plus (+) button so that the 9300 selection is highlighted.
6) Wait for the Menu to dis-appear.
7) Then, press the Menu button 2 times to bring back the "Color Control Menu".
8) Next, Press the SELECT button so that RED COLOR GAIN is selected.
9) Raise the value by pressing the Plus (+) button twenty (20) points if you have a MM50 monitor. If you have a MM70 monitor only raise the value by 15. NOTE: This will make your color change to a pinkish color. This is normal and the following two steps will correct it.
10) Repeat steps 7 to 9 but this time choose Green Color Gain and then Blue Color Gain.
WARNING! DO NOT ADJUST RED/GREEN/ or BLUE COLOR BIAS. ADJUSTMENTS TO THESE SETTINGS SHOULD BE DONE ONLY BY QUALIFIED PERSONNEL.
11) Examine the quality of the picture. If the brightness is not satisfactory contact technical support.
