Please note this is talking about an on-going issue with multiple monitors, multiple computers, multiple installations of Windows, etc. dating several years back (and of course, thousands of files). While some combinations of monitors, computers, graphics cards, and codecs have been better than others at dealing with this issue, I don't think it's just an issue with matching refresh rates.

try 60 hz plus smoothmotion for this file. this file is very strange with a refreshrate of 23.810 hz this is not part of the blu ray or dvd spec.
and nearly all movie have a refreshrate of 24000/1001 so the right refreshrate for these is 23p

I can't use 60hz with 2160p with this 4K monitor. Also, smooth motion usually makes this problem worse when the refresh rate of the monitor is already approximately at the source refresh rate, partly due to how very taxing smooth motion is at higher resolutions --- it's almost the equiv. of doubling the frame count in terms of processing power required from my experiments.
Anyway this problem was worse with a different 24Hz-capable monitor, and still occurs at 48Hz, while getting significantly worse at 60Hz with or without smooth motion.
Note that the judder isn't bad, it's just noticeable at times --- some files more than others --- and I want to see what I can do about it.
