[Help Wordpress] Fullscreen responsive Projekt on my Site

Hi Dmitry,

thank you for this wonderful peac of software, I like tthe bakend and the clearnes of it.

But I am little bit overwhelmed to find the right configuration for my projekt.
You can see the state here http://147535.webhosting55.1blu.de/wprogerkrebs/

My goal is it to fit the slider in this responsive templat so that it looks similar on a normal screen and also on the smartphone.
See my screenshots, but its difficutl to find out how it works.
The bigest challenge is it in the horizontal view.

My idea is it to set the slider in the center fullscreen and then set the collor from the backround of the slider as to the backroundcollor for the site, so nobody can see where the slider ends.
Or have you a better idea or sollution?
But how can I thell the slider to fit in every screenresolution the right sice.

I am happy when you can help me a little.

Thank you and all the best Roger

PS: Is the Slider influence the backroundcollor? Normally I can change this in the Design menue of the Slider
