MVrefresh doesn't work? Don't know what that is. As I said, use [url=http://www.guru3d.com/rivatuner/:7f442]RivaTuner[/url:7f442]. If you have a nVidia card, recent drivers and Windows, it works. Look better: After having installed RivaTuner, start it. Click on the button next to the lowest bar which says 'Customize...'. Click on the icon with '60 Hz.' on it. Click 'select all display modes' (bottom left). Then, click on >> (Set maximum refresh rate bla bla). Click 'Install' and close/reboot. You're done.

If this doesn't work, then either your monitor doesn't support higher refresh rates, or your monitor driver, or both.
