The problem is i always geting this resolution in windows... but i only get '800*640' maximum in redhat linux 9...
the i try to change (add the value 1024*780) the resolution entry of monitor in '/etc/X11/XF86config' to 1024*780... but after restarting the dispalay is not working. and also somthing like "HZ ?" is only display in monitor...
but i can enter into the system via non graphical mode (alt + cntrl + f1)...
how can i fix this problem...

This means that your monitor can't handle the mode that X tries to use.
1) See if you have the right horizontal/vertical resolutions
From what i get in google, your monitor support 30-55 kHz Horizontal and 50-120 Hz vertical
(

See in /etc/X11/XF86config if you have these values.
2) If you have these values then i guess the X server tries to use a "1024x768" (I guess you mean 768 and not 780)
that has a larger vertical resolution than your monitor supports. (your monitor supports 1024 × 768 @ 68Hz max)
You can make a modeline so that you can get the mode.
90% it is the first case. When redhat probed your monitor it put lower resolutions and you can't get decent modes.
