Override video refresh rate in MacOS X?

Discussion in 'Apple' started by Mitchell Spector, Oct 1, 2005.

  1. Rather simple question: I'm running MacOS X (10.2.8) and would like
    to set the video refresh rate to 85 Hz or higher. However if it's not listed
    in the 'Displays' preference, next to the resolution of your choice, the OS
    leaves you stuck with no option but what it provides (via auto-detect).

    In my particular case I wish to use 1152x870 at 85 or 90 Hz refresh.
    I'm only shown 75 Hz as an option (unless I increase or decrease the
    resolution, which I rather not do). Is there an OS X preference file I
    can edit to override the Displays setting? I know my display and video
    card are both capable of supporting 1152x870 @ 90 Hz, as I tested
    it on a PC to see if it syncs and it does.

    My setup is:

    - Beige G3
    - ATI Rage 128 (16 MB)
    - 19" NEC MultiSync FE991-SB (NO adapter used)

    Entering "resolution" into versiontracker's search box brought up a bunch
    of stuff, including these that look they do what you want:


    I haven't tried them myself.
