Hi Nigel,

Thanks for the info. This is desktop computer and I am using 17"
samsung SyncMaster 753DFX CRT monitor. Previously I noticed that
fedora used to set it to 85Hz at 1024x768. I guess internally its set
to right values because I don't have flickering problem in my monitor.
Only KDE is reporting a wrong value. May be its just have something to
do with KDE Desktop and Power management feature.

Thanks again
