Screen resolution and refresh rate problem


Hi to all!

I used to use Gnome. There, I used 1024x768, had 85Hz refresh rate (=vertical something???) and quite a nice time.
When I started using more graphical applications, and installed KDE in addition to my Gnome, I decided to change the resolution to 1280x1024.
After a few nice minutes, I discovered that the display flashes, and when I checked the refresh rate, I found out it was set on 60Hz. Any attempt to change that has failed. It drives me crazy...

My questions are:
* Is there a way to allow bigger refresh rate? (when I open display options and choose 1024x768, it ONLY allows 85Hz, and when I choose 1280x1024, it ONLY allows 60Hz.
* If not: is it my only option, to stay with either 1024x768 or 60Hz? It seems a bit strange, because my screen (Compaq FS740) is quite new and good...

Note:
I've read several posts regarding this subject, but found nothing I could understand (I'm not good at configuring stuff manually).
I did see something called gtf, and when I used "gtf 1280 1024 85 -x" I got:
Code:
  # 1280x1024 @ 85.00 Hz (GTF) hsync: 91.38 kHz; pclk: 159.36 MHz
  Modeline "1280x1024_85.00"  159.36  1280 1376 1512 1744  1024 1025 1028 1075  -HSync +Vsync
If you could make me understand what this means, and what I can do with this, it would be wonderful!

And a little information, if it helps:

What you have run into is hardware limitations. This web page gives the specs of the various resolution-speed combinations that the Compaq FS740 will run at.
