EDIDs only have two decimal places for the pixel clock. PowerStrip controls the video card directly through its own driver. I don't know any other program that can adjust the pixel clock with that much precision. I remember PowerStrip working with 5000/6000-series cards even though they're not officially supported. 7000-series cards won't work though.
So two reasons to change over from Powerstrip to CRU.
So what´s the problem? - As far as I can see, CRU allows setting the pixelclock frequency to 2 decimal places, that isn´t sufficient for a really accurate setting of the refresh rate for a movie to avoid framedrops/repeats. With Powerstrip there are 5 or 6 decimal places, that´s ok.
So, where sits the limitation of this within CRU and why can Powerstrip work more accurate?

Keep in mind that the hardware clock is not 100% accurate, so some adjustment will still be required to achieve an exact rate.
Is there an tool / excelfile / script to show combinations of the porches with corresponding pixelclock setting for a wanted refresh rate?
