Help: Monitor Frequency out of range


Could someone please assist. Linux RedHat 9.0
Followed all instructions to the letter no problems. As i am installing and it is running through the settings screen it gets to my monitor and all i get is
a blank screen with (Frequency out of range(50-60Hz)message)
TRIED ALL OPTIONS USING THE F-KEYS.
Monitor is: iilyama Model: s900mti 19" This is a standard svga monitor.
Graphics card is Chaintech FX20 128mb. nVidia GeForce FX5200, Checked to see if this card did not support Linux seems OK.
Processor AMD Athlon 2200.
Any assistance would not only be appreciated but i would owe you one.
Sorry its a bit long winded
Regards
Graham Walsh

You listed everything but the only thing that matters...

What is your monitor's vertical refresh rate? Look behind your monitor... it should state something like 50-60Hz or something similar.

After that use this value to be set in your /etc/X11/XF86Config file's VertRefresh configuration.

OK, now at the command prompt (as root) type pico /etc/X11/XF86Config

Look for a line looking like this (or something similar to it, the values may vary):
Code:
    VertRefresh 40-90
And change it to:
Code:
    VertRefresh 50-60
After that press Ctrl-X to exit pico, and choose Yes when it prompts you to save the file. Then try startx to see if it works.

In your XF86Config file there will be a Monitor section like mine below. Change your refresh rate to the ones for your monitor values.

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Dell M991"
DisplaySize 360 270
HorizSync 30.0 - 96.0
VertRefresh 50.0 - 160.0
Option "dpms"
EndSection
