I purchased your nice product. How can I make a full screen slider?
Do you mean "full width" or "full screen"?
If you mean "full width", in Amazing Slider, step 4, Options dialog, there is an option "Support responsive web design". Check this option, the the slider will be responsive, and will automatically fit its container. So if its container is full width, the slider will be full width. In "full width" mode, the slider will always maintain it's aspect ratio.
If you mean "full screen", the slider does not support it. We have a jQuery plugin product which can create a "full screen" gallery: http://html5box.com/html5gallery/index.php. The demo is here: http://html5box.com/html5gallery/demo_fullscreen.php and the tutorial is here: http://html5box.com/html5gallery/responsivedesign.php
