So, I've got a geForce 650 Ti Boost, on a CRT monitor. My ubuntu is the latest, and I use Nvidias propietary driver. I've tried all the things that I know of to set my refresh rate to 85 hz. I'ts a old monitor, but it serves me just right. I've tried to set on nVidias control pannel, to no avail, and to use compiz manager, again to no avail.
Can you help me to find another way to set the refresh rate?
