[Ari Torhamo <ari.torhamo@xxxxxxxxx>]

Public bug reported:

Binary package hint: xorg

Driver:              Nvidia 185
Graphics card: Nvidia Geforce 8800 GT, Nvidia Geforce GTX 275
Monitor:           Hitachi CM823F 21" CRT, 19" CRT

Expected behaviour:
Open the regular display configuration tool (not the one supplied by Nvidia) and have reasonable refresh rate options available for my monitor, which can handle 90 Hz @ 1600x1200. Typical options might be something like 90, 85, 75, 70, 65 and 60 Hz. Also expect the selected refresh rate and the one the monitor is using to be the same.

What happened:
Opened the regular display configuration tool, and found that available refresh rate options were seemingly very low. When I actually tried them, the refresh rates were different from what the numbers suggested. Here are the presented numbers on the left column and the actual refresh rates on the right:

64	60
63	65
62	70
61	75
60	85
59	90

Steps to repeat:
 - Go to System -> Settings -> Display
 - In Display Settings, open the drop-down list
 - Observe the available refresh rate options. If the bug manifests, they are too small.
 - Compare the selected refresh rate with the actual refresh rate of your monitor. If the bug manifests, they are not the same and the rate goes smaller when you choose a larger one.
