[Q] Record in 1080p or 2160p? topic

So i had my S5 for quite a while but still don't know which would be the better option. I went to a rave a few days ago and recorded with 2160p, but when transferring onto my computer with a usb cable, I was unable to play it on Window Media Player. The question is, would it be better for me to record at 2160p or 1080p? I do not have a 4k monitor, just a regular 1080p. What are the advantages if I record with 2160p instead of 1080p? And also is there a way to play my videos recorded in 2160p on window media player instead of having to download VLC?
