4K?

Before purchasing, I read on a few review sites that FBX can record in 4K. I don't see a 2160p option here.

There IS an "original" option in the resolution dropdown though. What is that?

'original' will make a recording in the native game resolution, so if the game is being played in 2160p, 'original' will make a recording at 2160p.
