17" crt monitor, but not all refresh rates showed

Only some refresh rates are displayed as an option.
Look xrandr:

$ xrandr
Screen 0: minimum 320 x 175, current 1280 x 1024, maximum 1600 x 1200
default connected 1280x1024+0+0 0mm x 0mm
   1600x1200      50.0     56.0  
   1400x1050      51.0     57.0  
   1280x960       52.0  
   1024x768       53.0     61.0     62.0     63.0     64.0  
   800x600        54.0     67.0     68.0     69.0     70.0     71.0     72.0  
   640x480        55.0     76.0     77.0     78.0     79.0  
   1280x1024      58.0*    59.0  
   1152x864       60.0  
   896x672        65.0  
   832x624        66.0  
   720x400        73.0  
   640x512        74.0     75.0  
   640x400        80.0  
   640x350        81.0  
   576x432        82.0  
   512x384        83.0     84.0     85.0     86.0     87.0  
   416x312        88.0  
   400x300        89.0     90.0     91.0     92.0     93.0  
   360x200        94.0  
   320x240        95.0     96.0     97.0     98.0  
   320x200        99.0  
   320x175       100.0

The weird value rates are fault of the nvidia driver telling jokes.

But how can i have more refresh rate in 1280x1024 than 1280x960? My monitor is a standard 4:3 crt.

I tried disabling EDIDs and specifying the sync values according to the monitor.
The monitor is a samsung syncmaster 700p.

Any ideas? Thanks in advance.

HEre is my xorg.conf:

Re: 17" crt monitor, but not all refresh rates showed

I see you have a nvidia card. For nvidia users xrandr displays wrong value. If you want to check exactly what you're running, search some of the monitor options, it should have it in there. Also use the nvidia-settings, but for me at times it too reported wrong refresh rates.
