John, I've never had this problem, but if I did, the first place I would look 
would be in the Monitor, Device, and Screen sections of /etc/X11/XF86Config.  
Start by doing a "man XF86Config" and try to get an idea of what it's all 
about.

Make sure you know the horizontal and vertical frequency ranges of your 
monitor and check them with the values in XF86Config Monitor section.  Check 
the device section to see it has the correct graphic card info.  Look at the 
screen section for combinations of your monitor and graphics card and see 
what resolutions are shown (800x600 or 1024x768, etc.).

Before you change any of the values in XF86Config, it would be wise to make a 
backup - cp /etc/X11/XF86Config /etc/X11/XF86Config.old so if you screw up 
something you can go back to fuzzy.

Have you tried cntl-alt-+ where the plus is on the keypad?  This steps 
through the available resolutions.

If you're not sure what resolutions you have, in KDE, use kruler.  Right 
click to adjust it.

Good luck, 
bruce
