Unfortunately, there are no width settings on it. It will default to the width of the module.
If that is what you want - you will have no problems. I would have liked to have been able to set the width independently.
As I wasn't able to do this I'm no longer using the Flexslider on the site it was originally bought for.
That said, their support was responsive and they got back to me with answers very quickly.
Unfortunately, though they weren't able to fix my issue.
