Not getting the highest resolution on my screen

I'm using a ViewSonic VP201b with a radeon 9600 xt 128 mb ddr Adapter. I booted fine and changed my resolution
to 1600 by 1200, but the screen goes black and I have to go into terminal mode, edit /usr/X11/xorg.conf changing
to a lower resolution to get going. It's a dual boot system and this monitor and adapter give flawless 1600 by 1200
under windows. How can I get the same resolution under Fedora core 3?

Thanks in advance...

Have you made sure to set the refresh rates, Vertical Refresh, Horizontal Sync
correctly, according to the monitor's specs?

Do you have a device section for the display adapter, and have you ensured the
driver and settings are correct?

I've set it up for the monitor and adapter, all that looks fine. I've also upgraded to the latest driver. xorg.conf has the correct settings for horizontal and vertical freqs. The only thing I see missing is the refresh rate should be 60, but I don't know how to specify it.

From the specification of ViewSonic VP201b:
http://www.viewsonic.com/products/desktopdisplays/lcddisplays/proseries/vp201b/
In xorg.conf, your monitor should be
HorizSync 30.0 - 92.0
VertRefresh 50.0 - 85.0

That's what I've got there. Do you know of any problems with that driver? I updated it from the viewsonic
site and it seemed to work. But I'm enough of a newbie at linux that I'm not sure. How can I check the
version number on it?

Thanks!

What version number do you mean?
