How to find out unknown CRT's frequencies

I'll be installing Slackware 12.0 on my brother's computer this weekend, but he's got a CRT display about which I have found no information anywhere on the Web.
He's currently running Windoze 2000 on it and it's set to 1024 x 768 at 16K resolution, so I know I can set up the X11 conf file for that at least, but I'd like to see how far I can push his CRT without blowing it up.
Is there some clever Dick out there that can tell me how to either:
- get the maximum Vertical and Horizontal scan frequencies of the CRT from some structure in Windoze 2000 or:
- have Slackware somehow test for the maximum frequencies automatically, i.e. without doing it manually?

Any clever solution will be highly appreciated.

Thanks in advance...

If Slackware includes the hwinfo utility, run this command:
/usr/sbin/hwinfo --monitor

That should tell you the maximum resolution and the vertical/horizontal frequency ranges.

Thanks for the reply bigrigdriver, unfortunately Slackware lacks that particular utility.
