Re: NVidia binary driver wrongly has been displaying 50Hz since 9xxx drivers
I've got basically the same problem, except; My computer is connected to the vga-in of the 27" Samsung lcd-tv, and when using any drivers 9xxx+ the refresh rate is 54hz. And the refresh really _is_ 54hz considering the flickering, so it's not just a problem in refresh rate reporting.
Using 8xxx drivers the refresh rate is 60hz and the flickering goes away. I haven't touched the xorg configuration, so the display mode is set to 1360x768_60. I've tried to use different modelines, but using them renders the 1360x768 resolution unusable by the xserver and forces the use of 1024x768 mode.
