Unfortunately the movie monitor its self cannot display decomposed fields. It displays what is inside the FDTD simulation.
However you can choose individual field component to display (click "field component" tab and choose).
If you want to watch CW movie, then you can display the decomposed field, such as left or right circular polarization using Matlab. Here is an example: https://optics.ansys.com/hc/en-us/articles/360034915793-Making-a-CW-movie-from-a-frequency-monitor
