I need the information about my monitor for xf86config, do you know of any software that can run in windows or a slackware console, to get this?

i don't think that running a software prog will give
you that info, mostly they say what rates are you using
at the moment the proggie runs. Or it would be a kind
of fronted to a hardware database
You better give your monitor brand and type
feed it to www.google.com or www.google.com/linux
and see what comes out use words like spec etc.
Or pay a visit at the manufacturers site

I've done both. And it hasn't helped.

some other possible things todo
put the brand/type in your next reply,
maybe someone has the same and knows what to
put in your XF86config.
Does the monitor have an OSD? if yes does it tell
the refresh rate? Then you should try different resolutions
in windows and write them down.
Or do you have the monitor floppy or cd, then
check your inf file edit it and see what resolutions
are used with the freq range.
if it is a common 17 inch, a vert rate of 75 or 85 will
do fine and is most likely not putting it over the edge but then
again i could be so wrong

Well if you have simple hardware you can just run the command:
XFree86 -configure

It should create the file ~/XF86Config.new
You can then test the config file with:
XFree86 -xf86config ~/XF86Config.new

If you see a gray screen with a working mouse then it should be working. You can then use this as the configuration file and maybe edit a few things.

If you really want to fine tune your monitor/graphics card then you might want to read the following document which describes it in detail:

OSD? I don't have any disks, or manuals.
I have two, a 1425 and 1525, I believe they are both 15 inch.

hmmm didn't know they were a little dated
they are compaqs right ? if yes then check these two links.

I think 1024x768 at 60 Hz for the 1525 maybe the possible highest to
use but that can be sore to your eyes . You can test it at
a higher rate but may risk some damage it starts sqeeking
at you,then you have overdone; hit ctrl+alt+backspace for X kill
the 1425 seems a 14 inch so 800x600 should be max

found these links using go.com this time
google brought a little to much commercial reselling crap

XFree86 won't work, I get a bash telling me the command doesnt exist.
I found out that 75,72,70,60 and 56 non interlaced will all work for the refresh rate, but I need the horizontal and vertical refresh rates for a 15 inch monitor.

seems your X server is n't installed
check it do: rpm -qa|grep -i xfree in a console

mine (on a mandrake box ) produces;

XFree86-4.2.0-10mdk
XFree86-75dpi-fonts-4.2.0-10mdk
XFree86-xfs-4.2.0-10mdk
XFree86-server-4.2.0-10mdk
XFree86-libs-4.2.0-10mdk
XFree86-100dpi-fonts-4.2.0-10mdk
XFree-devel-4.2.0-10mdk

for configuring X on redhat use Xconfigurator (be root)

since you're on redhat, use Xconfigurator: i believe somewhere along its interactive menus, it'll give away your monitor refresh rates(can't remember for sure... it's been some time since i touched Xconfigurator) among other things. take the opportunity to take it down if it does. it'll help in the long run.
