It seems that last time I tried that, though, I still had some stuttering. Does the "Actual" refresh rate field need to say 71.928hz?

That's what ReClock is for: http://www.videohelp.com/software/ReCloc...how-Filter

Even without ReClock, it should be very hard to notice stuttering at 3x the refresh rate, even if the refresh rate is slightly off. It's mostly a problem when the frame rate is close to the refresh rate, like 59.94 FPS at 60 Hz.

The "actual" value is there because the EDID can only store the pixel clock in MHz to two decimal places, so it shows the refresh rate with the pixel clock rounded up to the next possible value. The actual refresh rate is the pixel clock / horizontal total / vertical total.

I have a calculator that can figure out the pixel clock and totals needed to get a certain refresh rate: https://www.monitortests.com/pixelclock....=72&rate=1

The hardware might also have limitations that can affect the actual pixel clock rate, like the horizontal values might be rounded to multiples of 8, and I don't know how precise the pixel clock can be controlled on different video cards.
