How pixel clock is defined there? With ~300 kHz steps? > Pixel clock is defined as a number of picoseconds. > What modelines got you 60.02 and 59.98 Hz? > The modeline for 60.02Hz is: "3840x2160" 594.18 3840 4016 4104 4400 2160 2168 2178 2250 Though it should be noted that the clock value in modelines (594.18 in the line above) is actually converted and rounded to a picosecond value as ROUND(1000000 / [modeline clock]). In this case the actual pixel clock is 1683ps. > Btw, if they are really close to 60.02 and 59.98, than one step down > should be around 59.94. > None of the nearby values result in a good refresh rate: 1682ps - 60.05Hz 1683ps - 60.02Hz 1684ps - 59.98Hz 1685ps - 59.95Hz 1686ps - 59.91Hz It would be a bit strange to create recorder that can synchronize to 60 > and 59.94, > but cannot on other +-0.5% errors. > Conforming to SMPTE standards is the norm for recording / production equipment.
