After about 3 months of suffering from annoying stuttering and about 2 months of attempting to fix the stutter with new components and such, I finally set my refresh rate down to 100hz and found that the stutter has disappeared. I have a two monitor set up with an Acer GD235HZ being my main display. This monitor has a refresh rate of up to 120hz which is what I had it set on all this time until recently. QUESTION: All I would like to know is if the cause of the stutter is coming from the DVI cable or the monitor. I am also 100% certain that it's not any of the hardware in my ccomputer because it has all been replaced in the process of fixing the stutter.
