Change monitor refresh (RH9)
I just installed Redhat 9 last night and it went without a glitch. I then tried so set a different monitor (from the generic one that was suggested by the installer) and unfortunately chose the wrong one (too high refresh rate). During boot when the graphic mode is switched on, the image goes blurry because of the too high refresh rate.
How/where can I reset my monitor change? I do not have rescue disks or something like that. Do I have to reinstall the whole thing?
