Hi all, How can I set frequency of Monitor in XWindow? I found information of Monitor are specified in file /etc/X11/XF86Config.conf. In my RedHat Linux 8.0, Information of monitor are: Section "Monitor" HorizSync 30-85 VertRefresh 50-160 Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "Compaq V710 Color Monitor" Option "dpms" EndSection But, I can not found where to specify the frequency that Monitor works at. In Windows, I can choose any mode (Resolution and Frequence) of Monitor that Adapter supports such as: 1024 by 768, High Color (16 bit), 60 Hertz 1024 by 768, High Color (16 bit), 70 Hertz 1024 by 768, High Color (16 bit), 76 Hertz 1024 by 768, High Color (16 bit), 85 Hertz ...etc... by go to Start/Control Pannel/Display... but I don't know where in Redhat Linux to do this setting.
