Refresh Rate in Mac OS X Tiger (Mac mini)

in macOS edited January 2014

recently my LCD had broken down and I had to return it for some repairs. Unfortunately that means I had to connect my old CRT for temporary time being (LG Flatron F700B). But a strange thing is, that despite the fact that the os recognized the model of the display I can not set 1280x1024 by 85 Hz. If I set 1280x1024 resolution all i can choose from the refresh rate menu is 60 Hz. Is there any way to override this?

    Wouldn't that screen be 4:3, not 5:4, and wouldn't you thus want to use 1280x960?

    The common native resolution for any 4:3 17" LCD display is 1280x1024. This is the one I used with my 17" disp and that is the one I would like to use with the temporary CRT display.

    No matter even, becouse any resolution over 1024x768 works only in 60 Hz, and that sucks. This display is TCO '99 so every resolution works in 85Hz.

    1280x1024 is 5:4. 17-inch and 19-inch displays are commonly 5:4. Not 4:3.

    Your CRT is likely 4:3, ergo 1280x1024 would be stretched.

    Regardless, the real cause is probably that your CRT cannot display such a high resolution. I don't get how you come to the conclusion that TCO ratings have anything to do with that; they don't.

    This software might help:

    but as mentioned, maybe the display just doesn't support any higher.
