Got it!!!
Just remove some parts from style.css, 960_24_col_responsive.css, and slider-styles.css
Remove all sections like:
@media only screen and (min-width: 480px) and (max-width: 767px)
@media only screen and (max-width: 480px)
Just keep:
@media only screen and (min-width: 768px) and (max-width: 960px)
