OSD Contrast button not functioning

Probable cause: Nvidia direct access feature. Monitor displaying very low contrast, dark and dull colors. OSD contrast button is at setting "100", however it is not functioning to correct contrast value.

  • RE: OSD Contrast button not functioning

    I've solved the problem by entering monitors "service menu". To enter service menu:
    - press + buttons at the same time, screent will go blank and then will come back
    - open
    - bottom menu icon should display instead of normal
    - enter new menu, then
    - goto
    - press (incresase contrast button)
    - right bottom side of screen should display service menu
    - use arrow keys to adjust
    - contrast and brightness adjustments are and
    - adjust to proper values

    after doing adjustments, you may remove Nvidia's direct access functions. Follow these steps:
    - in windows explorer goto Windows\System32
    - delete or rename following files
    nvmccs.dll
    nvmccsrs.dll

    and, have a nice day.
