Why 24fps is not enough for HDR movies

[toad]

Hi people who want a crisp clear picture !,
I am getting delivery of a Sony KDL55-W955B , it's a replacement set due to my 46 inch W9 had a permanent vertical yellow line appear on the screen after only 5 months Doh ! .
Can anybody list the up to date calibration information so I can get a good set-up please ?
