True, 60hz is not good for a crt: now if only you had given the crt model #, brand name, people might have known the expected freq ranges available
And you have also not given your graphics card, which will also affect the frequency ranges available, nor have you said which driver you are using with this system
--the Ubuntu, Mint default seems to be the nouveau driver or a vesa mode driver, when the graphic card or the monitor is not known (in the hardware DB, Ubuntu set..)
Maybe you can start with, in a terminal
- Code: Select all
--to help us along with the problem
And yes, once the correct driver is running, you can set the resolution either directly in the /etc/X11/xorg.conf file or via the graphic card setup,: both ATI and Nvidia have a setup program which will create an xorg.conf file to match the monitor/graphic card, as well as possibly recognizing more monitor hardware types
