I read on the argyllcms release notes that the new version (1.5.1) supports measuring the refresh rate of the display. I was always curious to see if my TV supports "true" 24hz, or if it is instead doing a 3:2 pulldown and still running at 60Hz, so I tried to use the "spotread" tool to measure the refresh rate, but wasn't very successful.
I'm using a COlormunki Display (rebranded i1display2, pretty old), its listed as supported, but not sure what I'm doing wrong.
Did anyone happen to try to use this new function and know the correct command line? I simply tried spotread, and then "F" (also tried "f").
