How to center slideshow in header position

Hi,

I need to center a slideshow in header position but I have some problems.
In my monitor (1920x1080) I can see ok, but in others resolutions the images are not centered.

This is the website http://is.gd/vLHS2B

Hi

How do you center the slideshow to lower resolution when your slideshow have 1920px width?
My suggestion is to set background-image to header and them add your slideshow with lower size. For example 1000px width.

Cheers
