Problems with the display in Internet Explorer 10 - http://pcname not work. http://localhost works!

I have created a website in jquery mobile. I have the webserver (iis) on my local pc. I call the page with the ie10 via http://localhost, everything is displayed correctly (round buttons, the positioning, ...). If the Web page is accessed through http://pcname, the representation is reset to a minimum (square buttons, the positioning does not fit, ...). Can I änderrn? Is there an approach that appears to me it is also about http://pcname in "jquery mobile style"?

JQM-Version: 1.3.1
IIS 7.5


Thank you
